The United States Environ- mental Protection Agency (U SEP A) Section 319 National Monitoring Program is designed to provide information on pollution control efforts by documenting water quality changes associated with land treatment. The Section 319 National Monitoring Program projects comprise a small subset of NFS pollution control projects funded under Section 319 of the Clean Water Act as amended in 1987. Currently, projects are focused on stream systems, but USEPA intends to expand into ground water, lakes, and estuaries as suitable project criteria are developed. The goal of the program is to support 20 to 30 watershed projects nationwide that meet a minimum set of project planning, implementation, monitoring, and evaluation requirements designed to lead to successful documentation of project effectiveness with respect to water quality protection or improvement. The projects are nominated by their respective USEPA Regional Offices, in cooperation with state lead agencies for Section 319 funds. USEPA Headquarters reviews all proposals, negotiates with the regions and states regarding project detail, and recommends that regions fund acceptable projects using a regional 5% set-aside of Section 319 funds. The selection criteria used by USEPA Headquarters for Section 319 National Monitoring projects are primarily based on the components listed below. In addition to the specific criteria, emphasis is placed on projects that have a high probability of documenting water quality improvements from NFS controls over a 5- to 10-year period. • Documentation of the water quality problem, which includes identification of the pollutant(s) of primary concern, the source(s) of those pollutants, and the impact on designated uses of the water resources. • Comprehensive watershed description. • Well-defined critical area that encompasses the major sources of pollution being delivered to the impaired water resource. Delineation of a critical area should be based on the primary pollutant(s) causing the impairment, the source(s) of the pollutant(s), and the delivery system of the pollutants to the impaired water resource. • A watershed implementation plan that uses appropriate best management practice (BMP) systems. Systems of BMPs are a combination of individual BMPs designed to reduce a specific NFS problem in a given location. These BMP systems should address the primary pollutant(s) of concern and should be installed and utilized on the critical area. • Quantitative and realistic water quality and land treatment objectives and goals. • High level of expected implementation and landowner participation. • Clearly defined NFS monitoring program objectives. • Water quality and land treatment monitoring designs that have a high probability of documenting changes in water quality that are associated with the implementation of land treatment. ------- Chapter 1: Introduction • Well-established institutional arrangements and multi-year, up-front fund- ing for project planning and implementation. • Effective and ongoing information and education programs. • Effective technology transfer mechanisms. Minimum tracking and reporting requirements for land treatment and surface water quality monitoring have been established by USEPA for the National Monitoring Program projects (USEPA, 1991). These requirements should be considered as minimum guidelines for those projects whose objective is to evaluate water quality changes at a watershed or subwatershed level as a result of land treatment implementation. These minimum reporting requirements for Section 319 National Monitoring Program projects are listed in Appendix I. This publication is an annual report on the ten Section 319 National Monitoring Program projects and one ground water pilot project approved as of July 31, 1994. (A report on the Warner Creek, Maryland, 319 project, which is pending Section 319 National Monitoring Program project approval, is also included.) Project profiles were prepared by the North Carolina State University (NCSU) Water Quality Group under the USEPA grant entitled Nonpoint Source Wa- tershed Project Studies, and by the Oregon State University Water Resource Research Institute. Profiles have been reviewed and edited by personnel asso- ciated with each project. The ten surface water monitoring projects selected as Section 319 National Monitoring Program projects are Elm Creek (Nebraska), Lake Champlain (Vermont), Lake Pittsfield (Illinois), Long Creek (North Carolina), Morro Bay (California), Oak Creek Canyon (Arizona), Otter Creek (Wisconsin), Pequea and Mill Creek (Pennsylvania), Sny Magill (Iowa), and Sycamore Creek (Michi- gan). The eleventh project, Snake River Plain, Idaho, is a pilot ground water project. The Warner Creek (Maryland) 319 project is pending Section 319 National Monitoring Program project approval. Each project profile includes a project overview, project description, and maps. In the project description section, water resources are identified, water quality and project area characteristics are described, and the water qualitymonitoring program is outlined. Project budgets and project contacts are also included in the description. The Appendices include the minimum reporting requirements for Section 319 National Monitoring Program projects (Appendix I), a list of abbreviations (Appendix II), and a glossary of terms (Appendix III) used in the project profiles. A list of project documents and other relevant publications for each project is included in Appendix IV. ------- REFERENCES USEPA. 1991.

There are two important steps which, when taken during project initiation and planning, can significantly facilitate the linking of water quality improvements with the imple- mentation of land treatment practices or changes in land use. The two steps are: 1) selecting an appropriate watershed project and 2) documenting the water quality problem. Many factors, including project length, watershed size, water quality problem, and type of NFS pollution (i.e., urban, agricultural, etc.), combine to affect the probable success of NFS pollution control projects. These and other factors should be considered in the project selection process. Once a project has been selected, the water quality problem must be properly identified and docu- mented so that the project team can: 1) select and implement NFS controls that effectively address the problem and 2) design a monitoring effort that will detect water quality changes resulting from the land treatment implemented during the project. The following draft fact sheets are included to provide information and guid- ance on selecting water quality projects and documenting water quality prob- lems. The fact sheets were developed from lessons learned about the control of agricultural NFS pollution from the Rural Clean Water Program (RCWP). The RCWP was the largest federally sponsored experimental agricultural NFS control program implemented to date. The basis of the RCWP program was the combination of land treatment and water quality monitoring to document the effectiveness of NFS pollution control measures. Due to the complexity and scope of the RCWP, a great deal of information on watershed-based manage- ment was collected. A portion of this information is included in the two draft fact sheets entitled, Selecting an Agicultural Water Quality Project: The Rural Clean Water Program Experience and Identifying and Documenting a Water Quality Problem: The Rural Clean Water Progfam Experience. Although the focus of these fact sheets is agricultural, the principles can be applied to both rural and urban watersheds. ------- Chapter 2 The Rural Clean Water Pro- gram (RCWP), a 10-year feder- ally sponsored nonpoint source (NFS) pollution control pro- gram, was initiated in 1980 as an experimental effort to address agricultural NFS pollution problems in watersheds across the country. The RCWP is im- portant because it is one of the few national NFS control pro- grams that has combined land treatment and water quality monitoring in a continuous feedback loop to document the effectiveness of NPS pollution control measures. The RCWP was adminis- tered by the U.S. Department of Agriculture Agricultural Stabi- lization and Conservation Serv- ice in consultation with the U.S. Environmental Protection Agency. The Soil Conservation Service, Extension Service, Eco- nomic Research Service, Agri- cultural Research Service, U. S. Geological Survey, and many other agencies also participated. The 21 experimental RCWP projects, representing a wide range of pollution problems and impaired water uses, were lo- cated in Alabama, Delaware, Florida, Idaho, Illinois, Iowa, Kansas, Louisiana, Maryland, Massachusetts, Michigan, Min- nesota, Nebraska, Oregon, Pennsylvania, South Dakota, Tennessee/Kentucky, Utah, Vermont, Virginia,and Wiscon- Appropriate best manage- ment practices (BMPs) were used by producers to reduce NPS pollution from their farm- ing operations. Since participa- tion in the RCWP was voluntary, cost-share funds and technical assistance, provided by the fed- eral government, were offered to producers as incentives for us- ing or installing BMPs. SELECTING AN AGRICULTURAL WATER QUALITY PROJECT: The Rural Clean Water Program Experience Restoring or protecting water resources from nonpoint sources of pollution is critical in assuring good water quality. Watershed-level projects are ideal for improving or protecting a water resource from a total watershed perspective. However, controlling nonpoint source (NPS) pollution generally requires funding from public appropriations. To assure the best use of scarce financial resources, it is important to select those NPS pollution control projects that are the most viable and can succeed in either protecting threatened or restoring impaired water resources. A successful NPS pollution control project does not happen ran- domly: nonpoint source pollution control project selection is a difficult and time-consuming task. Projects need to be selected carefully based on an analysis of the technical and social factors within the watershed of concern. Because encouraging feedback is essential to project participants, the watershed community, and policy makers, watershed projects that have a high probability for reversing a water quality use impairment, or that contain highly valued water resources threatened by NPS pollution, should be given high priority. The technical factors involve: • the correct identification and documentation of the water quality problem(s); • analysis of the appropriate types and quantities of land-based treatment in the critical areas; • selection of a water quality problem that can be treated within the project's time frame and monetary constraints; and • monitoring to document changes in land treatment and water quality. Social factors that influence the effectiveness of any NPS pollution control project include: • commitment by the community and producers to control NPS pollution; (DRAFT 8/1/94) ------- Chapter 2 Water Resource Impairment and Water Quality Objectives and Goals RCWP Project Examples A well-defined water qual- ity problem statement was used to select the Taylor Creek - Nubin Slough RCWP project (Florida). Lake Okeechobee (the water re- source of concern), a multi- purpose freshwater lake, received excessive quantities of phosphorus- (pollutant) laden runoff from dairy farms (pollutant source) lo- cated on the Taylor Creek - Nubin Slough tributaries. High phosphorus inputs (magnitude of the pollutant) from agricultural areas, espe- cially the Taylor Creek - Nu- bin Slough drainage areas, were causing eutrophication (water use impairment) of Lake Okeechobee. Lower dissojved oxygen contents and increased plant growth were affecting drinking water standards, recreational use, and habitat quality of the lake. Because of the well-defined water quality problem state- ment, an effective best man- agement strategy (BMP) was designed with a quantitative goal to reduce by 50% phos- phorus concentrations of the water entering Lake Okeechobee from the water- shed. After BMP implemen- tation, phosphorus inputs into Lake Okeechobee from the Taylor Creek - Nubin Slough drainage areas were reduced by more than 50%. Conversely, the Massa- chusetts RCWP project was selected without a well-de- fined water quality problem statement. Since the water quality problem statement did not clearly define the source of the fecal coliform contami- nation (dairy farms or on-site waste management systems), dairy farmers were reluctant to participate in RCWP ac- tivities. Because of poor pro- ject participation, there was no documentable change in the water quality of the estu- ary. • implementation strategies selected by the sponsoring agencies and the agencies' ability to work together; and • multi-year funding sufficient to offer technical assistance, informa- tion and education, and cost-share for best management practice (BMP) implementation to ensure a high level of participation in the critical areas. Many of the 21 projects that participated in the Rural Clean Water Program (RCWP), an experimental NPS pollution control project, were successful in reducing the impacts of NPS pollution (Gale et. al., 1993). Each of these successful projects was able to uniquely combine the necessary technical and social factors that comprise an effective NPS pollution control project. Specific examples and lessons learned from RCWP on the selection of workable NPS pollution control projects are presented below, along with examples of specific RCWP projects. Water Resource Impairment and Water Quality Objec- tives and Goals One of the most critical factors when selecting a NPS pollution control project is to choose a project that has a well-defined water quality problem statement. In order to write a problem statement, the water quality problem must be correctly identified and documented. A water quality problem statement should include, at a minimum, the following factors: • the water resource(s) of concern; • the water use impairment(s) or threat of impairment(s); and • the pollutant, pollutant sources, and magnitude of the pollutant(s) causing the water use impairment A water quality problem statement should be used as the basis for selecting NPS pollution control projects. If all factors of the water quality problem statement are not clearly delineated, then the project should not be selected. Clearly defined and realistic water quality objectives and goals improve a projects probability of success. The water quality problem statement should be the basis for setting objectives and goals for both water quality and land treatment. The goals and objectives should be directly related to the water quality impairment or conditions threaten- ing designated uses. ------- Chapter 2 BMP Implementation Strategy RCWP Project Example Bacteria, sediment, and nutrients from dairy farms in the St. Albans Bay, Vermont RCWP project were enrich- ing the bay, causing high bac- teria counts, large algal blooms, and prolific macrp- phyte growth. These impair- ments resulted in beach closings, decreased shoreline property values, and overall declining recreational use of the bay. Dairy production was the dominant land use. The land treatment strategy was to treat 75% of the critical area. The critical area was de- fined as farmsteads delivering excessive phosphorus and fe- cal coliformto St. Albans Bay and was based on the amount of manure, distance from wa- tercourse, present manure management practices, and manure-spreading rates. The system of BMPs placed an emphasis on reducing phos- phorus and bacteria from ani- mal operations and cropland. By targeting appropriate farms and applying the right BMPs, fecal coliform and phosphorus decreased in tributaries feeding the bay. Treatable Water Quality Problem Within Project Time Frame and Monetary Constraints RCWP Project Example In the Vermont RCWP project, the upgrading of a wastewater treatment plant improved the water quality, but made analysis of water quality improvements associ- ated with the NFS land treat- ment program more difficult. In addition, no documented reductions of phosphorus oc- curred in St. Albans Bay over a 10-year period despite docu- mented reductions of phos- phorus and fecal coliform in the tributaries draining to the bay. It is thought that a period longer than 10 years will be required to document changes because of the accumulation of phosphorus in the Bay from previous inputs. BMP Implementation Strategy Best management practices are essential for any nonpoint source pollution control proj ect. One of the criteria for proj ect selection should include the technical merits of the BMP implementation plan, which is integrally tied to water quality impacts and project goals. Proposed plans must include critical area delineation within the watershed. A critical area should be delineated to identify and encompass the major pollutant sources that have a direct impact on the impaired water resource. Planned BMP implementation should be targeted to the critical area and primary pollutants. The BMPs proposed for the critical area should be selected such that the most effective system of BMPs .to reduce a particular pollutant is chosen. The system of BMPs should address both source reduction from the major pollutant sources and pollutant delivery reduction by minimizing transport of the pollutant to the water resource of concern. Additionally, there should be some indication (a goal) of the anticipated percent of BMP implementation (coverage) that will occur in the critical area. Delineating BMP systems and coverage is important for two reasons: to estimate the effectiveness of the BMP systems to meet water quality goals and to determine if proposed appropriations are sufficient to fund the necessary types and numbers of BMPs. Treatable Water Quality Problem Within Project Time Frame and Monetary Constraints The size of the critical areas, sources of pollutants, extent of BMPs needed in the critical area, cost per participant, and the cost per acre establish the economic and technical feasibility to control water quality problems. The size of the selected watershed project should allow for a large portion of the critical area to be treated. Also, the water resource of concern should be able to exhibit a measurable improvement from the estimated pollutant delivery reduction over the project lifetime. In addition, the project time frame needs to be sufficiently long to allow for adequate comparison between pre- and post-project conditions. Multi-year projects (usually greater than 5 to 10 years) should be given priority. Small watersheds (e.g., critical area of roughly 30,000 acres or less) are easier to treat and monitor and should, therefore, be given special consideration in the selection process. Nonpoint source pollution programs restricted to addressing agricul- tural sources should avoid watersheds that contain significant non-ag- ricultural nonpoint sources or point sources because pollutant loadings from these other sources often mask water quality changes associated with NPS controls. Other approaches, such as total watershed manage- ment, which include both point and all major nonpoint sources of pollution, can be effective inadequate resources are available. ------- Chapter 2 Water Quality and Land Treatment Monitoring to Document Changes in Land Treatment, Land Use, and Water Quality RCWP Project Example The Rock Creek, Idaho, RCWP project had a good monitoring design for docu- menting changes in water quality in subwatersheds and entire project areas. Land treatment and water quality monitoring occurred through- out the 10-year project time frame with consistent sam- pling before and after BMP implementation at multiple sites. Project personnel were able to isolate the effects of water management and sedi- ment control BMPs by moni- toring explanatory variables including season, stream dis- charge, precipitation, and land use. Participation and Community Support RCWP Project Example Initially in Minnesota, only a few farmers volun- teered to participate in a pro- ject to protect and restore a trout stream (Garvin Brook RCWP project). However, when the focus of the Minne- sota RCWP project changed from restoration of a trout stream to protection of the drinking water resource (the ground water), many farmers chose to participate. Water Quality and Land Treatment Monitoring to Document Changes in Land Treatment, Land Use, and Water Quality Water quality and land treatment monitoring plans that can ade- quately document changes in land treatment, land use, and water quality are important selection criteria for experimental watershed projects, especially in projects that have a goal of documenting both water quality changes and an association between land management and water quality improvements. Water quality monitoring can provide important feedback to project participants, other citizens, and policy makers. The potential of the project for monitoring, including two to three years of baseline data and evaluation feedback, is important. Participation and Community Support Gaging participation and community support are important when assessing the probable viability of a NFS pollution control project. Adequate participation is essential for a NFS pollution control project to succeed. Community support helps to pressure potential participants to cooperate. To ensure project participation, people must have a vested interest in solving the pollution problem. A vested interest in a NFS pollution control project comes about because the water resource is valued, the pollutant source is understood, and finally, because partici- pants recognize that they are part of the solution. Public benefits from the project that would increase the public value may include decreased human health threats, improved recreational use, or improved habitat or natural health of the water resource. Predicting producer participation in advance of project activities, in order to select a NFS pollution control project, is a difficult task. One good indicator for predicting participation is how highly valued a water resource is by the community. Another good indicator of potential project participation is the pres- ence of ongoing grass-root efforts to protect the water resource. Community support is also important to the success of NFS pollution control projects. Thus, it is also necessary to evaluate the expected level of community support before selecting a NFS pollution control project. Funds for cost-sharing and technical assistance should be committed at the state and local levels to assure local support. 10 ------- Chapter 2 Participation and Community Support (continued) RCWP Project Examples Tillamook Bay, a shell- fish-producing estuary, was impaired by fecal coliform contamination, which led to the closing of the shellfish beds and subsequent reduced shellfish harvest. A citizen's group, comprised of dairy farmers, fishermen, and busi- ness leaders, was formed prior to Tillamook Bay RCWP project activities in order to protect the estuary. There was almost 100% par- ticipation of area dairy farm- ers in the Tillamook Bay RCWP project. Fecal coli- form was reduced by over 50% and the majority of the shellfish beds were reopened for harvest. Peer pressure from the community (fishermen, bank- ers, the dairy cooperative) was essential in obtaining and maintaining project participa- tion in the Oregon RCWP project. Institutional Arrangements RCWP Project Example In the Oregon RCWP pro- ject, working relations be- tween the Oregon Depart- ment of Environmental Qual- ity, the USDA (United States Department of Agriculture) Soil Conservation Service, the USDA Agriculture Stabi- lization and Conservation Service, Oregon State Uni- versity, and the local dairy co- operative were established before the project was started. These groups were actively cooperating with each other to solve the problem of fecal coliform contamination of Tillamook Bay. Part of the success of the Tillamook Bay RCWP project was directly attributed to the strong insti- tutional arrangements that were forged prior to the initia- tion of RCWP project activi- ties and then were maintained throughout the life of the pro- ject. Institutional Arrangements Institutional arrangements are important for selecting NFS pollution control projects. Projects that have a dedicated staff, positive interac- tion between groups, cooperative attitudes, well-defined organiza- tional strategies, and a long-term commitment to the project processes are generally more successful at gaining and maintaining producer and community participation and support. The organizational strategy should include strong interagency cooperation with clearly outlined roles for each agency. Although it is difficult to judge the effectiveness of institutional arrangements prior to project activities, pre-project institutional arrangements can be useful indicators of future interactions and should be investigated prior to project selection. Funding Availability of funds for the life of the project is an important criterion for the selection of a NFS pollution control project. Nonpoint source pollution control projects need sufficient funds for the size of the critical area within the watershed and the problem that is being addressed. In the RCWP, each project designated critical areas (those areas that contribute the largest amount of pollutants to the water resource) for treatment. For most of the 21 RCWP projects, there was sufficient funding, regardless of the problem, for 75% treatment of critical areas with BMPs. Reliable funding is needed for long-term planning and budgeting, both essential components of NFS pollution control watershed projects that often take five or more years to implement. A short funding cycle that does not ensure full implementation of project activities reduces the effectiveness of projects. Sufficient tune and funds should be allocated to pre-implementation planning for meeting project goals. In addition, the pre-project planning period allows for acquisition of pre-project data, development of compatible / consistent data manage- ment and evaluation procedures, and selection of the most appropriate monitoring and modeling activities that enhance project evaluations. Best management practices are often too expensive for most agricul- tural producers to implement. Cost-share funds ease the economic burden of adopting BMPs. Results from a farm operator survey showed that access to cost-share money was determined to be the primary reason that producers participated in the RCWP. Because cost-share funds are significant to producer participation, one of the project selection criterion must include funding for BMP implementation. Participants in NFS pollution control projects need frequent advice about what type(s) of BMPs to use and how to implement and manage them. Without a strong technical assistance component, which in- cludes information and education (I&E), NFS projects will fail. 11 ------- Chapter 2 Funding RCWP Project Examples Unlike most agricultural NFS pollution control pro- jects, the RCWP was funded up-front, for a well-defined period of time (10 to 15 years). If all other selection criteria factors are equal, the project with the most reliable, long-term funding should be chosen. For example, in Alabama, an extension agent was cred- ited with obtaining and main- taining project support from area farmers. Because techni- cal assistance and I&B activi- ties are necessary project components, it is important that potential NFS pollution control projects include suffi- cient funding for technical as- sistance and I&E. Although state extension and the Soil Conservation Service offer these technical services free of charge, the additional workload may require funding for technical assistance. Additional money may also be re- quired for I&E activities that inform and educate participants and citizens about the project. Funding of technical and I&E services in the RCWP made possible the technical transfer of large amounts of infor- mation and was often credited as being essential to a project's success.

The RCWP is important because it is one of the few na- tional NFS control programs that has combined land treatment and water quality monitoring in a continuous feedback loop to document the effectiveness of NFS pollution control measures. The RCWP was administered by the U.S. Department of Agri- culture Agricultural Stabiliza- tion and Conservation Service in consultation with the U.S. Envi- ronmental Protection Agency. (U.S. EPA). The Soil Conserva- tion Service, Extension Service, Economic Research Service, Ag- ricultural Research Service, U.S. Geological Survey, and many other federal, state, and local agencies also participated. The 21 experimental RCWP projects, representing a wide range of pollution problems and impaired water uses, were lo- cated in Alabama, Delaware, Florida, Idaho, Illinois, Iowa, Kansas, Louisiana, Maryland, Massachusetts, Michigan, Min- nesota, Nebraska, Oregon, Penn- sylvania, South Dakota, Tennessee/Kentucky, Utah, Ver- mont, Virginia, and Wisconsin. Appropriate best manage- ment practices (BMPs) were used by producers to reduce NFS pol- lution from their farming opera- tions. Since participation in the RCWP was voluntary, cost-share funds and technical assistance, provided by the federal govern- ment, were offered to producers as incentives for using or install- ing BMPs. IDENTIFYING AND DOCUMENTING A WATER QUALITY PROBLEM; The Rural Clean Water Program One of the most critical steps in controlling agricultural nonpoint source (NFS) pollution is to correctly identify and document the existence of a water quality problem. The water quality problem may be defined either as a threat to the designated Use of a water resource or as a total or partial impairment of the designated use. The designated use of a water resource is set by each state's water quality agency and includes categories such as human consumption, agriculture, aesthetics, and recreation. Proper identification and documentation of a water quality problem requires gathering existing data from past or ongoing water quality studies. If adequate water quality data are not available to clearly document the problem and its source, a water quality problem identifi- cation and documentation monitoring program should be initiated. Monitoring should include both storm and baseflow sampling over a 6-18 month period. Depending on the pollutant(s) of concern, water quality monitoring may require measurements of chemical, physical, and biological factors. The results of the water quality monitoring studies should be synthe- sized, sometimes in conjunction with a pollutant budget, in order to produce a water quality problem statement. Clear problem identifica- tion and documentation should lead to a water quality problem state- ment that: • defines the water resource of concern; • delineates the water use impairment or threat of impairment and identifies its location and history; and • states the pollutant(s), the pollutant sources, and magnitude of the sources. Assumptions about the cause-and-effect relationship between pollut- ants and impairments should be stated. In addition, any habitat attrib- utes found to limit ecological health should also be included. The water quality problem statement provides the basis for a strategy to effectively remediate the water quality impairment and enhance the designated water resource use. The strategy is used to guide the selec- tion and placement of best management practices (BMPs) designed to reduce, remediate, or retard specific pollutants. A well-crafted water quality problem statement is also essential to ensure community con- sensus about the water quality impairment. (DRAFT 6/1/94) 13 ------- Chapter 2 The Importance of a Well-Crafted Water Quality Problem Statement RCWP Project Example The Florida RCWP project is an excellent example of how effective water quality problem identifica- tion and documentation can lead to improvements in water quality. Lake Okeechobee, a valued water resource in Florida, has been stud- ied since the early 1940's by the U.S. Geological Survey. A 1969 study that assessed the nutrient status of the lake indicated eutro- phic conditions (Fredrico et al., 1981). High nutrient levels, par- ticularly phosphorus, were leading to excess water plant growth and depleted oxygen levels, which was impairing fish and migratory bird habitats. In addition to other lim- nological studies, the water quality of the tributaries that flow into the lake was monitored for seven years (1973-1980). One tributary, the Taylor Creek-Nubin Slough, was contributing 28% of the total phos- phorus but only 5% of the water into Lake Okeechobee (Allen et al., 1982). Animal waste and fertilizer run- off from the large dairy farms (av- eraging more than 1,000 cows per herd) in the Taylor Creek-Nubin Slough watershed were the primary sources of the phosphorus. Be- cause thorough and long-term monitoring of all the tributaries en- tering Lake Okeechobee identified Taylor Creek-Nubin Slough as a major pollutant contributor, this watershed was selected as a RCWP project. Land treatment consisted of an aggressive system of BMPs de- signed to reduce phosphorus runoff from manure and fertilizer. As a direct result of the BMPs imple- mented during the RCWP, phos- phorus concentrations in the Taylor Crcck-Nubin Slough were de- creased by more than 50% (Gale et al., 1993). Communities are generally unwilling to expend the money and time necessary to combat NFS pollution unless they are convinced that a significant problem exists and that it can be rectified. The Rural Clean Water Program (RCWP) (see box on page 13) was a national program that demonstrated the importance of water quality problem identification and documentation to agricultural NFS pollution control projects (Gale et al., 1993). Lessons learned about problem identification and documentation from RCWP are presented in this fact sheet. The Importance of Problem Identification and Documentation The diffuse nature of NPS pollution, and its spatial and temporal variability, make it a difficult problem to treat. Pollutant sources can be difficult to identify and impacts may be subtle. Therefore, without adequate water quality problem documentation, NPS pollution cannot be successfully controlled. Many of the projects selected to participate in the RCWP had thorough water quality impairment investigations prior to project se- lection and initiation (see opposite box). This allowed project teams to prepare well-crafted water quality problem statements that led to ac- tions that enhanced water quality. Gathering Existing Data for Water Quality Problem Identification and Documentation The first step in identifying and documenting a water quality problem is to gather existing data on the water resource and the watershed. Water resource information includes past or ongoing water quality studies and information from the state 305(b) report. Any additional water quality studies should also be reviewed and summarized. This existing information may be available from the state water quality agency, U.S. Fish and Wildlife Service, U.S. Department of Agriculture (USDA) - Forest Service, or U.S. Geological Survey. Watershed data should be compiled to evaluate land use, soils, and climatic information. A land use map is one of the most important tools for watershed managers. Land use classifications include agricultural lands, animal operations, residential areas, commercial and industrial facilities, mining operations, parks, forests, and wetlands. Basic climatic information can be used to evaluate the times of the year when pollutant runoff is greatest and when drought or other factors are affecting water resource data. 14 ------- Chapter 2 Monitoring Complex Hydrologic Systems RCWP Project Example The water quality problem of the Oakwood Lakes - Poinsett RCWP project (South Dakota) in- itially seemed straightforward. Lake Poinsett and East & West Oakwood Lakes were found to be hyper-eutrophic by the National Eutrophication Survey (U.S. EPA) in 1977. The hyper-eutrophic con- ditions had occurred due to excess nutrient runoff from surrounding croplands and animal operations. Algae blooms, aquatic weeds, dis- solved oxygen depletion, and fish kills were common. Nutrient- and sediment-reduc- ing BMPs and waste management BMPs were imple- mented on the watershed's critical areas. (Critical areas are those portions of the wa- tershed that contribute dispropor- tionate amounts of the pollutant(s) to the receiving water resource). A very comprehensive monitoring program was conducted during the RCWP to assess the water quality of the lakes, tributaries, ground water, and runoff from farm fields. BMPs reduced sediment and the nutrients associated with the sedi- ment, and nutrients from animal sources (Gale et al., 1993). In spite of a reduction in pollut- ant, there was no change in the tro- phic status of the lakes. Further studies revealed that phosphorus from ground and surface water is trapped and stored in lake sedi- ments. This trapped phosphorus is continuously released into the water column, thus promoting hy- per-eutrophic conditions. Even without additional phosphorus in- puts, this recycling of phosphorus will occur for many years and con- tinue to impair water quality. Al- though the project failed to reduce the phosphorus levels of the lakes, it did provide detailed information and documentation on the water quality problem and the eutrophi- cation process in these types of prairie lake systems. Data for the watershed analysis may be available from local health departments, county planning departments, USDA - Soil Conservation Service (state or local offices), USDA - Agricultural Conservation and Stabilization Service, Soil and Water Conservation Districts, or county or regional Extension Service offices. In cases where existing data are not adequate to identify or document a water quality problem, water quality problem identification and documentation monitoring will be needed. Monitoring for Problem Documentation Program Design The objective of problem identification and documentation monitor- ing is to locate pollutant sources and ecological conditions contributing to the problem. The monitoring program must be designed such that at its conclusion an accurate water quality problem statement can be written, stating the water use impairments), the primary pollutant(s), and the sources of the pollutants. The program should employ both baseflow and stormwater quality monitoring. Baseflow monitoring documents ambient water quality conditions and problems. Storm sampling is useful for documenting the magnitude of the hydrologic and pollutant impacts. Runoff from agri- cultural activities (such as agrichemical and manure applications, irri- gation activities, and tillage operations) should be monitored. There are four major categories of water quality variables: 1) physi- cal properties, 2) chemical constituents, 3) biological organisms, and 4) habitat (Coffey et al., 1994). The categories and individual variables monitored will depend on the suspected water quality impairment and the extent to which the water resource has already been studied. Chemical constituents and physical assessments are the most fre- quently sampled and easiest to measure of the water quality variables. Physical assessment monitoring includes such variables as water temperature, turbidity, and sedimentation. Chemical assessment consists of monitoring both inorganic (nitrate, orthophosphate, metals) and organic constituents (pesticides, benzene). Biological monitoring should be utilized to assess designated water use attainment for aquatic life and should include monitoring variables such as coliform bacteria, benthic macroinvertebrates, and fish. Habitat monitoring is important for characterizing the ecological integrity of the water resource as well as an explaining primary biologi- cal variation. Habitat monitoring variables include stream, lake, or reservoir macroinvertebrate and fish habitat. 15 ------- Chap iter2 The Importance of Pollutant Source Determination RCWP Project Example In Tennessee and Kentucky, Lake Reelfoot, which supports commercial fishing and sportfish- ing and migratory birds, is threat- ened by siltation. The water quality impairments and primary pollut- ants were identified and docu- mented correctly before the commencement of the Lake Reel- foot RCWP project. However, the contributing pollutant sources were not sufficiently quantified (Gale et al, 1993). The two primary sources of sediment in this watershed are cropland and naturally occurring gullies. A sediment budget, indicating the relative contributions of each of these pollutant sources, should have been completed prior to pro- ject implementation. A sediment budget would have been useful to the project team in selecting the most effective placement of BMPs for reducing erosion. Another study of Reelfoot Lake, conducted during the RCWP time frame, indicated that some of the small watersheds not originally targeted for BMP installation were contributing significant amounts of localized sediment and should have been included as part of the critical area. Later studies confirmed the need for winter cover crops that were not promoted as part of the RCWP project Finally, results of a pollutant delivery study indicated that dcchannelizing area streams and tributaries would have reduced sediment loading into Lake Reel- foot. Had the studies mentioned above been conducted prior to the implementation of the RCWP pro- ject, a more complete water quality problem statement would likely have been written, leading to in- creased accuracy in critical area definition and more appropriate se- lection and placement of BMPS. Depending on the water resource being studied, monitoring stations may be established at: 1) tributaries; 2) main-stem streams; and 3) estuaries, lakes, reservoirs or wetlands in order to determine the water quality impairment and the primary pollutant, and possibly thepollutant source. Tributary stations are often useful for identifying pollutant sources and the magnitude of the pollutant. Simply monitoring the main-stem stream (primary drainage channel or lake) is inadequate to identify sources of pollutants because the receiving water dilutes and assimilates tributary inputs, making identification of specific sources difficult. Tributary stations should be located immediately above and below suspected NFS pollution discharge areas to facilitate pollutant source identification. For example, in the Oregon RCWP project, tributary stations were used to document the type(s) and magnitude of pollutants entering Tillamook Bay from individual dairy farms. Data collected at main-stem stream stations provide an aggregate of the water conditions upstream. Main-stem monitoring is useful because it helps explain the pollutant dilution 'and assimilation that occurs in large streams. The water quality variables measured for the main-stem stream station should match those monitored in the tributaries. In the Florida RCWP project, for example, phosphorus, the major pollutant of concern, was carefully monitored in both main-stem streams and tributaries. Monitoring stations located in reservoirs, lakes, estuaries, or wet- lands can provide useful information about the amount and fate of pollutants reaching the water resource. These stations should be stra- tegically positioned to evaluate the impact of the pollutant on the designated water use. For example, in the Oregon RCWP project, estuarine monitoring stations were located in or near shellfish beds so that fecal coliform contamination could be precisely monitored. Monitoring Duration and Frequency Water quality problem identification and documentation monitoring should usually be conducted for 6 to 18 months. However, watersheds with complex hydrologic conditions may require more than 18 months of monitoring for adequate water quality identification and documen- tation. For continuous streams, baseflow monitoring of physical and chemi- cal constituents should occur with sufficient frequency to ensure detec- tion of water quality changes caused by climatic impacts and watershed activities. The tuning of biological monitoring should correspond to the type and stage of the organism being documented. Guidance on timing for biological monitoring should be available from the state water quality agency. 16 ------- Chapter 2 The Role of a Strong Water Quality Problem Statement in Assuring Community Support for a Project RCWP Project Example Another RCWP project in which the water quality impairment was correctly identified and docu- mented was the Tillamook Bay RCWP project. Tillamook Bay> lo- cated in northwestern Oregon, con- tains important commercial and recreational shellfish resources. Due to fecal coliform contamina- tion originating from dairies lo- cated near the estuary, shellfish beds were frequently closed to har- vesting. As part of the water qual- ity planning for Section 208 of Public Law 95-217 (The Clean Water Act), studies conducted by the U.S. Food and Drug Admini- stration, the Oregon Department of Environmental Quality, and U.S. Department, of Agriculture (USDA) Soil Conservation Service quantified bacteria counts and the timing of the contamination and de- lineated the major land areas that were the primary source of the bac- teria. Fecal coliform was reduced by over 50% in the estuary after BMPs were implemented on more than 80% of all dairy farms in the region (Gale etal., 1993). Detailed prob- lem identification and documenta- , tion was instrumental in the construction of a good water qual- ity problem statement. This state- ment was used to convince all segments of the community - dairy producers, concerned citizens, fish- ermen, dairy; cooperative execu- tives, lenders - that the fecal coliform water quality problem had to be solved by the dairy farmers, working in conjunction with fed- eral, state, and local agencies, to reduce contamination of shellfish beds. Timing of storm sampling is critical. Water quality samples should be taken during the rise, peak, and fall of stream level during runoff. Peak seasonal flows should be collected. For example, if snow melt is substantial, monitoring during this time is important. Pollutant Budget Existing watershed data and problem identification and documenta- tion monitoring may be insufficient to entirely clarify the exact nature of the water quality problem. In some NFS projects it may be necessary to quantify the relative proportion of the pollutant contributed by each source (create a pollutant budget). Pollutant budgets address only the pollutant that directly contributes to the water quality problem. For example, in the Tennessee RCWP project, where several sources of sediment contributed to the siltation of Reelfoot Lake, a pollutant budget was not constructed for the lake. The consequence of this lack of information about the relative proportion of sediment entering the lake from the various sources was that critical areas contributing the greatest amount of sediment were not correctly identified and the most effective BMPs were not implemented. The Importance of Preparing a Water Quality Problem Statement After all pertinent preliminary water quality information has been obtained, water quality data have been collected, and a pollutant budget prepared (if necessary), a detailed water quality problem statement should be written. A comprehensive water quality problem statement describes the water resource; the water quality impairment or threat to designated use; habitat limitations; and the type, source, and magnitude of the pollutant(s). The problem statement is essential because it clearly states the water quality impairment and its source(s). The problem statement can be used by the project team to guide in selecting and siting appropriate BMPs. A comprehensive water quality problem statement can also be useful because it provides a clear explanation of the water quality problem and its causes to community members. Consensus within the community about the water quality problem and the approach being taken to address the problem is essential to project success. 17 ------- Chapter 2 Keys to Water Quality Problem Identification and Documentation • Prioritize problem identifica- tion and documentation as a first step to designing an ag- ricultural nonpoint source pollution control project • Gather existing water quality data from past or ongoing water quality studies. This information should include a physical description of the water resource and the water- shed; a designated use of the water resource; and water quality data that indicates a water quality impairment or potential threat to the water resource. • Water quality monitoring for problem documentation should ensue if existing water quality data is inadequate to sufficiently identify and document the water quality problem. • Water quality monitoring for problem documentation should include both storm and baseflow. • A minimum of 6-18 months of monitoring is necessary for problem documentation. • The type of variable - chemi- cal, physical, and/or biologi- cal - will depend on the sus- pected designated use impair- ment of the water resource. • The results of the water qual- ity studies should be synthe- sized, along with any useful land-based data, to produce a water quality problem state- ment. • Well-crafted water quality problem statements should lead the project team toward the selection of the appropri- ate systems and locations of BMP. A good problem state- ment will also help solidify community support to reduce nonpoint source pollution. Sometimes the water quality problem statement is written correctly the first tune. In other cases, the statement may have to be rewritten as additional information becomes available. In the Illinois RCWP pro- ject, for example, the project team originally thought that excess lake turbidity was caused by general erosion (Gale et al., 1993). However, monitoring conducted during the project indicated that a particular type of soil (natric soils) was causing most of the turbidity because saline soil particles from the natric soils do not settle. Once the pollutant source was accurately determined, a new problem statement was writ- ten and land treatment efforts were redirected toward the natric soils. References Allen, L.H., Jr., J.M.

It drops approximately 2,700 feet from its source along the Mogollon Rim to its conver- gence with the Verde River. There are several gaining reaches that contribute to the perennial flow of the creek. The flows vary from a low of less than one cubic feet per second (cfs) to a high snowmelt-contributed flow of over 1800 cfs. The average annual flow within the study area, Oak Creek Canyon, is approxi- mately 13 cfs. The Oak Creek Canyon National Monitoring project focuses exclusively on that segment of water located in the canyon portion of Oak Creek, a 13-mile steep-walled area of the creek. Oak Creek Canyon is a narrow strip of deep- canyon land extending from the City limits of Sedona, thirteen miles northward to the Mogollon Rim. The canyon width varies from one mile at the northern tip to approximately three miles in the south. Although Oak Creek Canyon water- shed encompasses 5,833 acres, only 907 acres are considered critical. The major land use of the canyon area is recreational. The U.S. Forest Service and State Parks have developed campgrounds, parking lots, picnic areas, and scenic views along the Congressionally designated Scenic Highway, Route 89A. Pri- vate homes and businesses account for much of the remaining land use. The Oak Creek National Monitoring project focuses on the implementation and documentation of integrated best management practice (BMP) systems for three locations: Slide Rock State Park, Pine Flats Campground, and Slide Rock Parking Lot. The eleven-acre Slide Rock State Park is used by more than 350,000 swimmers and sunbathers each season. The water quality at this site has historically been characterized by large seasonal fecal coliform loads. Pine Flats Campground accommodates approximately 10,000 campers each season. Runoff from the campground delivers fecal coliform and excess nutrients into Oak Creek. Slide Rock State Park parking lot accommodates over 90,000 vehicles each season. Runoff of pollutants associated with automobiles drains into Oak Creek. The BMPs to be implemented at Slide Rock State Park and Pine Flats Camp- ground include enhancing the restroom facilities, better litter control through more intense monitoring by State Park officials of park visitors, and the promo- tion of visitor compliance with park and campground regulations on facilities' use, littering, and waste disposal. The BMPs to be implemented at the Slide Rock Parking Lot include periodic cleaning of the detention basin, promotion of an aerobic environment in the basin, periodic sweeping of the parking lot, and, if necessary, retrofitting the detention basin itself. A paired-site upstream/downstream water quality monitoring design will be used to evaluate the effectiveness of BMPs on improving water quality at Slide Rock State Park. Grasshopper Point, a managed water recreation area similar to Slide Rock State Park, will serve as the control. Water quality monitoring stations will be located upstream and downstream of both the Slide Rock (treatment) and Grasshopper Point (control) swimming areas. A paired-site upstream/downstream water quality monitoring design will also be used for 23 ------- Oak Creek Canyon, Arizona Pine Flats Campground and Manzanita Campground. Manzanita will serve as the control site while Pine Flats will serve as the treatment site. As before, monitoring stations will be upstream/downstream of campground sites. For these two studies, weekly grab samples will be taken on Saturday afternoons from May 15 through September 15 for seven years starting in 1994. The Slide Rock Parking Lot study will evaluate the effectiveness of a detention basin designed to limit pollutants from entering into the Creek. An event-based BMP-effectiveness monitoring scheme will be used. Automatic samplers, trig- gered by rainfall, will be installed at inflow and outflow points of the detention basin. Each one will collect samples of the first flush and composite periodic samples of the rainfall. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments Oak Creek cuts deep into the southern rim of the Colorado Plateau. It drops approximately 2,700 feet from its source along the Mogollon Rim to its conver- gence with the Verde River. The Creek averages around 13 cubic feet per second (cfs) at the study area, but increases to 60 cfs downstream at its conflu- ence with the Verde. The study sites for this project are located in Oak Creek Canyon. This portion of the watershed is characterized by steep canyons and rapid water flows with sharp drops forming waterfalls and deep, cold pools. Oak Creek Canyon is the primary recreational area in the watershed. Designated beneficial uses of Oak Creek include full body contact (primarily in Oak Creek Canyon), cold water fishery and wildlife habitat (primarily Oak Creek Canyon), drinking water (along the entire course), agriculture (the lower third), and livestock watering (lower third). Oak Creek is designated as a Unique Water, with very high water quality standards. Oak Creek was designated as a Unique Water by the Arizona State Legislature in 1991 on the basis of (1) its popularity and accessibility as a water recreation resource; (2) its aesthetic, cultural, educational, and scientific importance; and (3) its importance as an agricultural and domestic drinking water resource in the Verde Valley. Two other criteria contributed to the designation of unique- ness: (1) Oak Creek Canyon is susceptible to irreparable or irretrievable loss due to its ecological fragility or its location, and (2) a surface water segment shall not be classified as unique water unless such segment is capable of being managed as a unique water. Management considerations shall include techni- cal feasibility and the availability of management resources. Biological, nutrient, and vehicular pollutants pose the most serious and pressing current threat to Oak Creek water quality. Oak Creek water quality is impaired by high fecal coliform levels, probably resulting from residential septic systems and the high usage of the campgrounds and day-use swimming areas by over 350,000 people during a concentrated period of time extending from May through September. Excessive nutrients, particularly phosphorus, which ex- 24 ------- Oak Creek Canyon, Arizona ceeds the 0.10 standard, threaten the water integrity of two impoundments located well below Oak Creek that provide a major source of drinking water for the City of Phoenix. The third type of pollution impairing Oak Creek is associated with motor vehicles. Heavy metals (such as lead and zinc), petro- leum hydrocarbons, and total organic carbons, from the estimated four million vehicles traveling along State Highway 89A each year and from numerous parking lots in the Oak Creek Canyon area, drain into Oak Creek during rainstorms and snow melts, threatening all designated uses. Pre-Project Water Quality Water Recreation and Camping Areas Human pathogens (bacteria and viruses) contaminate the Canyon segment of Oak Creek. Most of the attention has focused upon Slide Rock State Park and Grasshopper Point, the two managed "swimming holes" in the area. Fecal coliform counts peak in the summer during the height of the tourist season. Fecal Coliform Levels by Season Date July 15 August 15 June September Fecal Coliform Count (# /100 mH 463.7 392.5 61.2 54.3 Nutrient levels, especially phosphorus, are also of concern, as shown below: Pine Flats Campground phosphorous (P) concentrations (the annual aver- age standard is 0.10 mg/1) Date June, 1993 July, 1993 August, 1993 February, 1993 March, 1993 April, 1993 P(mg/l) 0.14 0.28 0.41 0.12 0.20 0.12 .Slide Rock Parking Lot Preliminary data suggest that the Slide Rock Parking Lot detention basin (a large, baffled concrete vault) is contributing to rather than reducing environ- mental damage. Approximately four feet of stagnant water remains in the vault at all times. The data collected (see table below) indicates that the heavy rainfall cleanses the parking lot of pollutants and also flushes out significant amounts of pollutants contained in the detention basin. 25 ------- Oak Creek Canyon, Arizona Current Water Quality Objectives Project Time Frame Project Approval Water Quality of the Detention Basin Time DO(mg/l) pH Zn(ug/l) Before Rain 0.0 4.79 222 July, 1993 After Rain 4.5 6.6 38 October,1993 Water Recreation Project Objectives: • A 50% reduction in fecal coliform • A 20% reduction in nutrients, particularly ammonia • A 20% reduction in total organic carbons (TOC) corresponding with a reduction in biological oxygen demand (BOD) Camping Project Objectives: • A 50% reduction in fecal coliforms • A 20% reduction in nutrients Slide Rock Parking Lot Objectives: • A 25% reduction of automobile-related pollutants that enter Oak Creek 1994 to 2001 1994 PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorologic Factors The entire Oak Creek watershed encompasses 300,000 acres. The project area, Oak Creek Canyon, encompasses 5,833 acres. However, the critical area com- prises only 907 acres. Flow in Oak Creek ranges from an average 13 cfs, in the higher Oak Creek Canyon area, to 60 cfs at its confluence with the Verde River. Annual precipitation in the Oak Creek watershed varies from a six-inch average in the Verde Valley to 20 inches per year on the higher elevations of the Mogollon rim. The majority of rainfall occurs during July and August of the rainy season (July 4 to September 15). Summer rainfall storm events are short and intense in nature (rarely lasting for more than a half-hour) and are sepa- rated by long dry periods. In a normal summer season, over twenty rainfall events will occur. Perennial flow in Oak Creek is sustained by ground water flow. The main source of ground water is the regional Coconino Aquifer. The majority of aquifers in the Oak Creek watershed are confined or artisan. Within the Oak 26 ------- Oak Creek Canyon, Arizona Creek watershed, ground water flow is generally to the south, paralleling topog- raphy toward the low-lying valley floor.

INFORMATION, EDUCATION, AND PUBLICITY Numerous organizations and individuals perceive themselves as "owners" of Oak Creek Canyon. It is in the best interest of the Oak Creek National Monitoring Program project to fully involve these groups and individuals in informational and educational activities. The Oak Creek Advisory Committee, which was formed in 1992, involves federal, state, and local government agencies and private organizations such as Keep Sedona Beautiful and the Arizona River Coalition. The committee meets monthly to: keep participants informed of current project activities and results; gain insights to areas of concern; and learn about the suggested BMPs that will be implemented as part of the 319 National Monitoring Program. NONPOINT SOURCE CONTROL STRATEGY Slide Rock and Grasshopper Point (Water Recreation Project) The access and ambience of restroom facilities, located at the Slide Rock swimming area, will be enhanced. Littering laws will be enforced by park officials to reduce the amount of trash that is disposed of in unauthorized areas. Finally, social strategies will be implemented to promote compliance of park regulations. Pine Flats and Manzanita (Campgrounds Project) The nonpoint source control strategy for the campground project targets the upstream site of Pine Flats. Best management practices implemented at Pine Flats are designed to reduce pollutants associated with human use of camp- ground facilities. The BMPs that will be implemented include the installation 27 ------- Oak Creek Canyon, Arizona of an enclosed shower for campers, enforcement of a clean zone between the creek and the campground, and the promotion of the use of existing restroom facilities. Direct contact by park personnel with visitors and the addition of more visible signs will help accomplish these goals. Slide Rock (Parking Lot Project) The BMP strategy focuses on reducing runoff from the parking lot and parking lot detention basin. The existing detention basin will be cleaned out prior to and after the rainy season. An aerobic environment within the basin will be pro- moted and street sweeping of the parking lot will occur. WATER QUALITY MONITORING Design Variables Measured The water recreation project, which is a paired-site upstream/downstream monitoring design, will be used to document the change in water quality as a result of the application of BMPs. The swimming sites at Slide Rock State Park (treatment site) and the Grasshopper Point (control site) will be the paired comparison. There will be water quality monitoring stations located above and below each swimming area. The camping area project will also use a paired-site upstream/downstream monitoring design. The camping area at Pine Flats (treatment site) and the site at Manzanita (control site) have been selected for project monitoring. Up- stream/downstream water quality monitoring stations will be installed at both sites. A BMP effectiveness water quality monitoring design will be used for the Slide Rock Parking Lot study. Sampling will take place at the inflow point and the outflow point of the detention basin.

Planning is ongoing. • The Colorado Plateau Biological Survey has established a major riparian study project focusing on the Beaver Creek/Montezuma Wells area of the Verde Valley. Members of the Oak Creek Canyon National Project are active participants in all of these groups. Activities are under way to consolidate and to coordinate these efforts. 31 ------- Oak Creek Canvon. Arizona OTHER PERTINENT INFORMATION Subsequent to plan approval and the on the basis of data obtained during the first-year monitoring season, the Coconino County Health Department, in conjunction with the Arizona Department of Environmental Quality, U.S. Forest Service, Arizona Department of Transportation, Arizona Park Service and others, confirmed that fecal coliform levels were alarmingly high at Slide Rock State Park. The health department ordered closure of the facility until such time as (1) fecal levels decrease significantly and (2) a plan is presented for assuring that dangerous fecal levels are reduced in the future. The Oak Creek Canyon National Monitoring Project plan forms the basis for proposed BMPs. Planning is under way to have at least two proposed BMPs in place by the 1995 season: (1) U.S. Forest Service has allocated funds to refurbish the single restroom located at the water's edge of Slide Rock State Park and (2) Arizona Department of Transportation is planning to erect per- manent parking barricades on State Highway 89A so that Slide Rock atten- dance is restricted to parking lot capacity (141 vehicles). The project possesses sufficient preliminary data to assure that the basic moni- toring plan remains intact.

This 76-square mile watershed is an important biological and economic resource. Two creeks, Los Osos and Chorro, drain the watershed into the Bay. Included within the watershed boundaries are two urban areas, prime agricultural and grazing lands, and a wide variety of natural habitats that support a diversity of animal and plant species. Morro Bay estuary is considered to be one of the least altered estuaries on the California coast. Heavy development activities, caused by an expanding population in San Luis Obispo County, have placed increased pres- sures on water resources in the watershed. Various nonpoint source pollutants, including sediment, bacteria, metals, nutri- ents, and organic chemicals, are entering streams in the area and threatening beneficial uses of the streams and estuary. The primary pollutant of concern is sediment. Brushland and rangeland contribute the largest portion of this sedi- ment, and Chorro Creek contributes twice as much sediment to the Bay as Los Osos Creek. At present rates of sedimentation, Morro Bay could be lost as an open water estuary within 300 years unless remedial action is undertaken. The objective of the Morro Bay Watershed Nonpoint Source Pollution and Treat- ment Measure Evaluation Program is to reduce the quantity of sediment enter- ing Morro Bay. The U.S. Environmental Protection Agency (USEPA) Section 319 National Monitoring Program project for the Morro Bay watershed has been developed to characterize the sedimentation rate and other water quality conditions in a portion of Chorro Creek, to evaluate the effectiveness of several best manage- ment practice (BMP) systems in improving water quality and habitat quality, and to evaluate the overall water quality at select sites in the Morro Bay watershed. A paired watershed study on tributaries of Chorro Creek (Chumash and Wal- ters Creeks) will be used to evaluate the effectiveness of a BMP system in improving water quality (Figure 4). Other monitoring sites, outside the paired watershed, have been established to evaluate specific BMP system effective- ness. In addition, water quality samples will be taken throughout the watershed to document the changes in water quality during the life of the project. PROJECT DESCRIPTION Water Resource Type and Size The total drainage basin of the Morro Bay watershed is approximately 48,450 acres. The monitoring effort is focused on the Chorro Creek watershed. Chorro Creek and its tributaries originate along the southern flank of Cuesta Ridge, at elevations of approximately 2,700 feet. Currently three stream gages are operational in the Chorro Creek watershed, one each on the San Luisito, San Bernardo, and Chorro creeks. Annual discharge is highly variable, ranging 37 ------- Morrow Bay Watershed, California from approximately 2,000 to over 20,000 acre-feet, and averaging about 5,600 acre-feet. Flow is intermittent in dry years and may disappear in all but the uppermost areas of the watershed. In spite of the intermittent nature of these creeks, both Chorro and Los Osos creeks are considered cold-water resources, supporting anadromous fisheries (steelhead trout). Water Uses and impairments Pre-Project Water Quality Morro Bay is one of the few relatively intact natural estuaries on the Pacific Coast of North America. The beneficial uses of Morro Bay include recreation, industry, navigation, marine life habitat, shellfish harvesting, commercial and sport fishing, wildlife habitat, and rare and endangered species habitat. A number offish species (including anadromous fish, which use the Bay during a part of their life cycle) have been negatively impacted by the increased amount of sediment in the streams and the Bay. Sedimentation in anadromous fish streams reduces the carrying capacity of the stream for steelhead and other fish species by reducing macroinvertebrate productivity, spawning habitat, egg and larval survival rates, and increasing gill abrasion and stress on adult fish. Al- though trout are still found in both streams, ocean-run fish have not been observed in a number of years. Accelerated sedimentation has also resulted in significant economic losses to the oyster industry in the Bay. Approximately 100 acres of oyster beds have been lost due to excessive sedimentation. Additionally, fecal coliform bacteria carried by streams to the Bay have had a negative impact on the shellfish industry, resulting in periodic closures of the area to shellfish harvesting (SCS, 1992). Elevated fecal coliform counts have been detected in water quality samples taken from several locations in the watershed. Elevated fecal coliform detections, exceeding 1600 Most Probable Number/100 ml, have generally been found in areas where cattle impacts in streams are heavy. The Tidewater Goby, a federally endangered brackish-water fish, has been eliminated from the mouths of both Chorro and Los Osos creeks, most likely as a result of sedimentation of pool habitat, in combination with excessive water diversion. The two creeks that flow into the estuary (Chorro Creek and Los Osos Creek) are listed as impaired for sedimentation, temperature, and agricultural non- point source pollution by the State of California (Central Coast Regional Water Quality Control Board, 1993). Studies conducted within the watershed have identified sedimentation as a serious threat in the watershed and estuary. Results of a Soil Conservation Service (SCS) Hydrologic Unit Areas (HUA) study show that the rate of sedimentation has increased ten-fold during the last 100 years (SCS, 1989b). Recent studies indicate that the estuary has lost 25% of its tidal volume in the last century as a result of accelerated sedimentation and has filled in with an average of two feet of sediment since 1935 (Haltiner, 1988). SCS estimated the current quantity of sediment delivered to Morro Bay to be 45,500 tons per year (Soil Conservation Service, 1989b). 38 ------- Morro Bay Watershed, California Current Water Quality Objectives Modifications Since Project Initiation Project Time Frame Project Approval The overall goal of the USEPA 319 project is to evaluate improvements in water quality resulting from implementation of best management practices. The following objectives have been identified for this project: • Identify sources, types, and amounts of nonpoint source pollutants (see the list of variables that will be monitored) originating in paired watersheds in the Chorro Creek watershed (Chumash and Walters Creeks). • Determine stream flow/sediment load relationships in the paired watersheds. • Evaluate the effectiveness of BMPs implemented as a BMP system in improv- ing water quality in one of the paired sub-watersheds (Chumash Creek). • Evaluate the effectiveness of three implemented BMP systems in improving water or habitat quality at selected Morro Bay watershed locations. • Monitor overall water qualityin the Morro Bay watershed to identify problem areas for future work, detect improvements or changes, and contribute to the database for watershed locations. • Develop a Geographical Information System (GIS) database to be used for this project and in future water quality monitoring efforts.

Relevant Hydrologic, Geologic, and Meteorologic Factors The Morro Bay watershed drains an area of 48,450 acres into the Morro Bay estuary on the central coast of California. The Bay is approximately four miles long and one and three-quarters miles at its maximum width. The project area is primarily located in the northeast portion of the Morro Bay watershed. Morro Bay was formed during the last 10,000 to 15,000 years (SCS, 1989a). A post-glacial rise in sea level of several hundred feet resulted in a submergence of the confluence of Chorro and Los Osos creeks (Haltiner, 1988). A series of creeks that originate in the steeper hillslopes to the east of the Bay drain westward into two creeks, Chorro and Los Osos, which drain into the Bay. The 400-acre salt marsh has developed in the central portion of the Bay in the delta of the two creeks. A shallow ground water system is also present underneath the project area. The geology of the watershed is highly varied, consisting of complex igneous, sedimentary, and metamorphic rock. Over fifty diverse soils, ranging from fine sands to heavy clays, have been mapped in the area. Soils in the upper water- shed are predominantly coarse-textured, shallow, and weakly developed. Deeper medium- or finer-textured soils are typically found in valley bottoms or on gently rolling hills. Earthquake activity and intense rain events increase landslide potential and severity in sensitive areas. 39 ------- Morrow Bay Watershed, California The climate of the watershed is Mediterranean: cool, wet winters and warm, dry summers. The area receives about 95% of its 18-inch average annual precipita- tion between the months of November and April. The mean air temperatures range from lows around 45 degrees in January to highs of 75 degrees in October, with prevailing winds from the northwest averaging around 15 to 20 miles per hour. Land Use Approximately 60% of the land in the watershed is classified as rangeland. Typical rangeland operations consist of approximately 1,000 acres of highly productive grasslands supporting cow-calf enterprises. Brushlands make up another 19% of the watershed area. Agricultural crops (truck, field, and grain crops), woodlands, and urban areas encompass approximately equal amounts of the landscape in the watershed. Land Use Acres Agricultural Crops 3,149 Woodland 3,093 Urban 3,389 Brushland 8,319 Rangeland 26,162 Total 44,112 Source: SCS, 1989a 7 7 8 19 59 100 Pollutant Source(s) Modifications Since Project Started It has been estimated that 50% or more of the sediment entering the Bay results from human activities. Sheet and rill erosion account for over 63% of the sediment reaching Morro Bay (SCS, 1989b). An SCS Erosion and Sediment Study identified sources of sediment to the Bay, which include activities on rangeland, cropland, and urban lands (SCS, 1989b). The greatest contribution of sediment to the Bay originates from upland brushlands (37%) because of the land's steepness, parent material, and lack of undercover, as well as rainfall. Rangelands are the second-largest source of sediment entering into streams (12%). Cattle grazing has damaged riparian areas by stripping the land of vegetation and breaking down bank stability. The unvegetated streambanks, as well as overgrazed uplands, have resulted in accelerated erosion. Other water- shed sources that contribute to sediment transport into Morro Bay include abandoned mines, poorly maintained roads, agricultural croplands, and urban activities. None. 40 ------- Morro Bay Watershed, California INFORMATION, EDUCATION, AND PUBLICITY Progress Towards Meeting Goals At least one informal educational program on the 319 National Monitoring Program project and the watershed will be conducted each year. Information and education (I&E) programs, thus far, have been workshops about the water quality problems within the watershed for landowners and local agencyperson- nel and a presentation before the Central Coast Regional Water Board. Future public presentations about the Morro Bay 319 National Monitoring Program project will be made to such local advocacy or other interest groups as Friends of the Estuary, the Morro Bay Natural History Association, and the Morro Bay Task Force, as well as Cal Poly State University (Cal Poly) and Cuesta Commu- nity College. Presentations on the monitoring program have been made at a Regional Water Quality Control Board public hearing and at the annual Soil and Water Conser- vation Society Conference (California Chapter). In addition, educational out- reach efforts were made at a Cooperative Extension erosion control workshop, the Morro Bay Museum of Natural History, a 4-H watershed education day, the California Biodiversity Council, and a Cal Poly soil science class. Publicity has included an excellent article in the local newspaper and a featured spot on the local evening news. NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Paired Watershed BMP Systems at Sites within the Morro Bay Watershed In the paired watershed, a BMP system will be used to control nonpoint source pollutants. Cal Poly will be responsible for implementation ofthis BMP system on Chumash Creek, which is one of the streams in the paired watershed. The BMPs to be implemented include: 1) fencing the entire riparian corridor; 2) creating smaller pastures for better management of cattle-grazing activities; 3) providing appropriate water distribution to each of these smaller pastures; 4) stabilizing and re vegetating portions of the streambank; and 5) installing water bars and culverts on farm roads where needed. During the project, riparian vegetation is expected to increase from essentially zero coverage to at least 50% coverage. The project team has established a goal of a 50% reduction in sediment following BMP implementation. SCS has established three different BMP systems throughout the watershed. These three systems will be evaluated for their effect on water and habitat quality. A floodplain sediment retention project will be established at Chorro Flats to retain sediment (sediment retention project). A riparian area along Dairy Creek, a tributary of Chorro Creek, will be fenced and revegetated (cattle exclusion project). Fences will be installed to allow rotational grazing of pas- tures on the 1,400-acre Maino ranch (managed grazing project). The goals for these projects during the next 10 years are to achieve a 33.8% decrease in sediment yield from the sediment retention project, a 66% reduction in sedi- ment yield from the cattle exclusion project, and a 30% reduction in sediment as a result of the managed grazing project. 41 ------- Morrow Bay Watershed, California Modifications Since Project Started Progress Towards Meeting Goals None. Paired Watershed Study: Funding has been acquired through CWA 319(h) for implementation of improvements on the paired watershed. A Technical Advi- sory Committee has been formed, and planning has begun for specific place- ment of land improvements needed on the Chumash Creek watershed. Sediment Retention Project: The Chorro Flats project has obtained funding ($90,000) for the engineering design of the flood plain restoration project. All environmental documents have been completed, but installation is still a few years away. Cattle Exclusion Project: Dairy Creek fencing for riparian exclusion has begun and will be completed this summer. Managed Grazing Project: The Maino Ranch has completed installation of watering devices and fencing and, as of this year, is being managed as planned in a timed grazing project. WATER QUALITY MONITORING Design Two watersheds have been selected for a paired watershed study. Chumash Creek (400 acres) and Walters Creek (480 acres) both drain into Chorro Creek. These creeks have similar soils, vegetative cover, elevation, slope, and land use activities. The property surrounding these two creeks is under the management of Cal Poly. Because the rangeland being treated is owned byCal Poly, project personnel will be able to ensure continuity and control of land management practices. The paired watershed monitoring plan entails three specific monitoring tech- niques: stream flow/climatic monitoring, water quality monitoring, and biologi- cal/habitat monitoring. The duration of the calibration period (the period during which the two watersheds will be monitored to establish statistical relationships between them) will be at least two rainy seasons. After the calibra- tion period is complete, a BMP system will be installed in one of the watersheds (Chumash Creek). The other watershed, Walters Creek, will serve as the control. Other systems of BMPs will be established at different locations in the Morro Bay watershed. Water quality will be monitored using upstream/downstream and single station designs to evaluate these systems. An upstream/downstream design will be adopted to monitor the water quality effect of a floodplain/sedi- ment retention project and a cattle exclusion project. A single station design on a subdrainage will be used to evaluate changes in water quality from implemen- tation of a managed grazing program. In addition to BMP effectiveness monitoring, ongoing water quality sampling will take place at selected sites throughout the Morro Bay watershed to docu- _ 42 ------- Mono Bay Watershed, California ment long-term changes in overall water quality and to discern problem areas in need of further restoration efforts. Modifications Since Project Started Variables Measured Sampling Scheme Because of very limited runoff during the 1993-1994 sampling year, only one sampling event occurred. Unless the winter of 1994-1995 is very wet, it may be necessary to extend to three seasons the calibration period for the paired watersheds. Biological Fecal Coliform Riparian vegetation Chemical and Other Suspended and bedload sediment Turbidity Nitrate (NOs-N) Total phosphate Conductivity pH Explanatory Variables Precipitation Stream flow Evaporation Animal units Weekly grab samples will be taken for at least 20 weeks during the rainy season, starting on November 15. The samples from the paired watershed will be analyzed for suspended sediment, turbidity, nitrate, total phosphate, and fecal coliform. The two upstream/downstream sites and one of the downstream monitoring sites will be analyzed for suspended sediment, turbidity, and fecal coliform. In addition, year-round samples for pH, dissolved oxygen, turbidity, temperature, and fecal coliform will be conducted every two weeks at these locations, the gage stations, and several additional sampling sites. In the paired watershed, suspended sediment samples will be collected during storm events using automated sampling equipment set at even intervals (30- minute or hourly intervals, depending on the sediment/flow relationship). The water collected from each individual sample will be analyzed for suspended sediment, turbidity, and conductivity. Bedload sediment will be sampled after each flow event (4 to 10 events per rainy season) for total mass. Physical (particle size) analysis will be performed on composite bedload samples. Vegetation will be assessed via aerial photography conducted bi-annually in March and September during the first, fifth, and tenth years of the project. On both the paired watershed and the Maino property, four permanent vegetation 43 ------- Morrow Bay Watershed, California Modifications Since Project Started Progress Toward Meeting Goals Water Quality Data Management and Analysis transects will be conducted two times each year to sample vegetation and document changes during the life of the project. Modifications will be made to sediment analysis techniques in upcoming years. This year, evaporation was used to process suspended sediment samples; how- ever, dissolved solids are high in this watershed and were contributing signifi- cantly to the total weight of the samples. In the future, analysis will be for total filterable solids. A relationship between conductivity and dissolved solids will be developed to convert this year's data to filterable solids. In addition to suspended solids and turbidity, conductivity will be measured for each sus- pended sediment sample during event monitoring. However, composite sam- ples from event monitoring will no longer be analyzed for total N, total P, or pH. Grab sampling will continue unchanged for nitrate, total P, pH, conductivity, and turbidity. The winter of 1993-1994 was atypical; only one rainfall event produced signifi- cant runoff. Sediment, turbidity, and flow data from this event were collected. A year of even interval grab sampling was obtained, with sampling conducted once every two weeks. During the rainy season (20 weeks beginning December 15), grab samples were collected once per week. A coshocton sampler was installed to collect flow from a small drainage on the Maino property, but flows were insufficient to start sample collection. Though the study design requires even-interval sampling year round, this is not feasible in several locations (including the paired watersheds) because the flow becomes intermittent or ceases entirely during summer months. Data Management Data and BMP implementation information will be handled by the project team. As required by the USEPA Section 319 National Monitoring Program Guidance, data will be entered into STORET and reported using the Nonpoint Source Management System Software. A geographical information system (GIS), ARC/INFO, will be used to map nonpoint pollution sources, BMPs, and land uses, and to determine resulting water quality problem areas. A Quality Assurance Project Plan, for project water quality sampling and analysis, will be developed by the Central Coast Regional Water Quality Con- trol Board. The plan will be used to assure the reliability and accuracy of sampling, data recording, and analytical measurements. Data Analysis Parametric and non-parametric statistical tests will be adopted to analyze the data. Possible tests include linear regression F-tests, analysis of variance, covariance F-test, Wilcoxon-Rank Sum tests, and Kendall's Tau test. A two- way contingency table will be used for comparison of the levels of pollutant concentrations and levels of explanatory variables. Three variable contingency tables will also be prepared; these include time (season or year), pollutant concentration, and an explanatory variable (such as flow or land treatment). 44 ------- Morro Bay Watershed, California Modifications Since Project Started Progress Toward Meeting Goals None. A draft Quality Assurance Plan has been developed and implemented. It is currently being circulated along with the annual report for review. GIS data layers entered this past year (using ARC/INFO) included sample site locations, soils, vegetation, land use, and topography. Initial analysis of the data has been relatively simple, including basic statistics and graphical representation of water quality parameters versus flow.

IMPACT OF OTHER FEDERAL AND STATE PROGRAMS In addition to the USEPA 319 National Monitoring Program project being led by the California Central Coast Regional Water Quality Control Board, several other agencies are involved in various water quality activities in the watershed. The California Coastal Conservancy contracted with the Coastal San Luis Resource Conservation District in 1987 to inventory the sediment sources to the estuary, to quantify the rates of sedimentation, and to develop a watershed enhancement plan to address these problems. The Coastal Conservancy then provided $400,000 for cost share for BMP implementation by landowners. HUA grant funding has been obtained for technical assistance in the watershed ($140,000/year), Cooperative Extension adult and youth watershed education programs ($100,000/year), and cost share for farmers and ranchers ($100,000/year) for five years. An SCS Range Conservationist was hired 45 ------- Morrow Bay Watershed, California through 319(h) funds ($163,000) to manage the range and farm land improve- ment program. Cooperative Extension has also received a grant to conduct detailed monitoring on a rangeland management project in the watershed. The California National Guard, a major landowner in the watershed, has contracted with the SCS ($40,000) to develop a management plan for grazing and road management on the base. State funding from the Coastal Conservancy and the Department of Transportation has been used to purchase a $1.45 million parcel of agricultural land on Chorro Creek just upstream of the Morro Bay delta which will be restored as a functioning flood plain. Without the cooperation of these agencies and without their funding, this project would be unable to implement BMPs or educate landowners about nonpoint source pollution. Modifications Since Project Started None. OTHER PERTINENT INFORMATION The Central Coast Regional Water Quality Board is conducting a study of the abandoned mines in the watershed with USE PA 205(j) funds. The Board has also obtained a USEPA Near Coastal Waters grant to develop a watershed work plan, incorporate new USEPA nonpoint source management measures into the Basin Plan, and develop guidance packages for the various agencies charged with the responsibility for water quality in the watershed. The Department of Fish and Game Wildlife Conservation Board has provided funding ($48,000) for steelhead habitat enhancement on portions of Chorro Creek. The State Department of Parks and Recreation has funded studies on exotic plant invasions in the delta as a result of sedimentation. The California Coastal Commission has used Morro Bay as a model watershed in development of a pilot study for a nonpoint source management plan pursuant to Section 6217 of the Federal Coastal Zone Management Act Reauthorization Amend- ments of 1990. In addition to state and federal support, the Morro Bay watershed receives tremendous support from local citizen groups. The Friends of the Estuary, a citizen advocacy group, has been invaluable in its political support of Morro Bay, including an effort to nominate the Bay for the National Estuary Program. The Bay Foundation, a non-profit group dedicated to Bay research, has funded a $45,000 study on the freshwater influences on Morro Bay, has developed a library collection on the bay and watershed at the local community college, and is actively cooperating with the Morro Bay National Monitoring Program pro- ject in development of a watershed GIS database. The Bay Foundation has also recently purchased satellite photographs of the watershed, which will prove useful for the monitoring program effort. The Friends of the Estuary and the Bay Foundation of Morro Bay are cooperating to develop a volunteer monitor- ing program for the Bay itself, which includes water quality monitoring. 46 ------- Morro Bay Watershed, California Recently, the California legislature passed Assembly Bill 640. This bill was written by the Friends of the Estuary and carried by Assemblywoman Andrea Seastrand. It establishes Morro Bay as the first "State Estuary," and mandates that a comprehensive management plan be developed for the bay and its watershed by locally involved agencies, organizations, and the general public. Current effort is under way to organize the steering committee for this planning process.

The aquifer also serves as a important source of water for irrigation. In 1990, this aquifer was designated by the U.S. Environ- mental Protection Agency (USEPA) as a sole source aquifer. Many diverse crops are produced throughout the Eastern Snake River Plain region. Excessive irrigation, a common practice in the area, creates the poten- tial for nitrate and pesticide leaching and/or runoff. Ground water monitoring indicates the presence of elevated nitrate levels in the shallow aquifer underly- ing the project area. The objective of a five-year United States Department of Agriculture (USD A) Demonstration Project within the Eastern Snake River Plain (1,946,700 acres) is to reduce adverse agricultural impacts on ground water quality through coordinated implementation of nutrient and irrigation water management (Fig- ure 6). As part of this project, two paired-field monitoring networks (con- structed to evaluate best management practices (BMPs) for nutrient and irrigation water management effects) are funded under Section 319 of the Clean Water Act (Figure 7). PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments In the intensely irrigated areas overlying the Eastern Snake River Plain aquifer, shallow, unconfined ground water systems have developed primarily from irri- gation water recharge. Domestic water supplies are often supplied by these shallow systems. Within the project area, the general flow direction of the shallow ground water system is toward the north from the river; however, localized flow patterns due to irrigation practices and pumping effects are very common. This ground water system very vulnerable to contamination because of the 1) proximity of the shallow system to ground surface, 2) the intensive land use overlying the system, and 3) the dominant recharge source (irrigation water)of the ground water. Some wells sampled for nitrate concentrations have exceeded state and federal standards for allowable levels. This occurrence of elevated nitrate concentra- tions in the ground water impairs the use of the shallow aquifer as a source of drinking water. Low-level pesticide concentrations in the ground water have been detected in domestic wells and are of concern in the project area. Both nitrate and potential pesticide concentrations threaten the present and future use of the aquifer system for domestic water use. 53 ------- Eastern Snake River Plain. Idaho Pre-Project Water Quality Current Water Quality Objectives Modifications Since Project Initiation Project Time Frame Project Approval Ground water data collected and analyzed within the project area indicate the widespread occurrence of nitrate concentrations that exceed state and federal drinking water standards. In a study conducted from May 1991 through Octo- ber 1991, 195 samples were taken from 54 area wells and analyzed for nitrate. Average nitrate concentrations were around 6.5 milligrams per liter (mg/1), with a maximum of 28 mg/1. The federal Maximum Contaminant Level (MCL)for nitrate of 10 mg/1 was exceeded in 16 % of the wells at least once during the sampling period. Five percent of the wells yielded samples that continuously exceeded the MCL during the sampling period. Ninety-eight samples were collected from the same 54 wells and analyzed for the presence of 107 pesticide compounds. Fourteen of the 54 wells yielded samples with at least one detectable pesticide present, but all concentrations measured were below the federal Safe Drinking Water MCL or Health Advi- sory for that compound. Even though the wells now meet MCL standards, pesticide concentrations are still believed to be a future concern for the Eastern Snake River Plain Aquifer. The overall Demonstration Project objective is to decrease nitrate and pesticide concentrations through the adoption of BMPs on agricultural lands. Specific project objectives for the USEPA 319 National Monitoring Program project are: • Evaluate the effects of irrigation water management on nitrate-nitrogen leaching to the ground water. A paired-field, referred to as "M," will allow a comparison of ground water quality conditions between regular irrigation scheduling and the use of a 12-hour sprinkler duration. • Evaluate the effects of crop rotation on nitrate-nitrogen leaching to the ground water. A paired-field study, referred to as "F," will allow a com- parison of water quality conditions between the side planted in grain and the side planted in beans.

The ground water quality monitoring activities are limited to a 30,000-acre area of south Minidoka County. The 319 project consists of two sets of paired five-acre plots (a total of four five-acre plots) located in this 30,000-acre area (Figure 6). The paired-fields are located in the eastern and western portions of the area to illustrate BMP effects in differing soil textures. The "F" field soils are fairly clean, fine to medium sands. The "M" field soils are silty loams. Due to the differences in soils and the traditional irrigation methods employed on these 54 ------- Eastern Snake River Plain, Idaho Relevant Hydrologic, Geologic, and Meteorologic Factors Land Use fields (flood and furrow respectively), the "M" field has relatively lower spatial variability of existing water quality than the "F" field. The "F" field also shows greater influences from adjacent fields. A regional monitoring well network consisting of existing domestic standpoint (driven) wells has also been established within the Demonstration Project Area. The regional network is intended to augment the paired-field data and provide a means to document the influence of the Demonstration Project on the quality of the area's shallow ground water system. The average annual rainfall is between 8 and 12 inches. Shallow and deep water aquifers are found within the project area. Because of the hydrogeologic regime of the project area, there is a wide range of depths to ground water. Soils in the demonstration area have been formed as a result of wind and water deposition. Stratified loamy alluvial deposits and sandy wind deposits cover a permeable layer of basalt. Soil textures vary from silty clay loams to fine sandy loams. These soils are predominantly level, moderately deep, and well drained. Sugar beets, potatoes, and grains are grown in the "M" field. Alfalfa, dry beans, and grains are grown in the "F" field. Both fields were converted to sprinkler from furrow and flood irrigation in 1993. Comparison demonstrations between sprinkler and gravity irrigation systems are not occurring because project per- sonnel feel that this information is apparent and available. The "M" paired field will be used to establish existing baseline conditions which exist using a "wheel line" sprinkler system. After baseline conditions have been established, the water application rate to the "BMP" side of the paired field will be approximately half of the control side. Pollutant Source(s) Baseline conditions, which exist under sprinkler-irrigated alfalfa production, will be established on the "F" paired field. After baseline conditions have been established, the "BMP "side of the paired field will be planted in grain, while the "control" side of the field will be planted in beans. Within the project area there are over 1,500 farms with an average size of 520 acres. A wide variety of crops, including alfalfa, barley, dry beans, corn, pota- toes, sugar beets, and wheat are grown in the area. Nutrient management on irrigated crops is intensive. Heavynitrogen application and excessive irrigation are the primary causes of water quality problems in the shallow aquifer system. In addition, over 80 different agrichemicals have been used within the project area. Excessive irrigation may cause some leaching of these pesticides into ground water (Idaho Eastern Snake River Plain Water Quality Demonstration Project, 1991). Modifications Since Project Started During implementation of the regional domestic well water quality monitoring portion of the USD A project, agricultural chemicals and nitrate-nitrogen have been detected at levels of concern and measured in samples collected from domestic wells. The herbicide Dacthal has been detected at low levels in samples collected from one well during each sampling event. The same well yielded a single sample with 2,4-D measured at 195 ppb. Other wells have yielded samples containing nitrate-nitrogen as high as 30 mg/1. Concern gener- 55 ------- Eastern Snake River Plain, Idaho ated by this data has led to site-specific ground water investigations by the Idaho Division of Environmental Quality and Idaho Department of Agriculture. In addition, limited sampling and analyses of ground water drainage systems, irrigation return flows, and injection wells have identified nutrients and pesti- cides in certain surface water bodies within the project area. Nitrate-nitrogen concentrations have been measured in subsurface tile drain effluent as high as 8 mg/1. The herbicides MCPA and 2,4-D have been detected in return flow irrigation water. The 2,4-D was measured at levels greater than the allowable Safe Drinking Water MCL of 70 ppb. Concern generated from evaluation of this data has prompted Department of Environmental Quality (DEQ) to re- quest an expansion of the existing surface water quality monitoring efforts. INFORMATION, EDUCATION, AND PUBLICITY Presently, there is no plan to implement a separate information and education (I & E) campaign for the 319 National Monitoring Program project. I & E for the Snake River 319 National Monitoring Program project will be included in the Demonstration Project I & E program. Progress Toward Meeting Goals Two Eastern Snake River Plain Demonstration Project brochures have been published. One brochure, targeting the local public, was designed to provide a general explanation of the project. The second explains results from the nitrate sampling of the project area. A survey was conducted to gain insight into the attitudes of the general public and the farmer. The results of these surveys have been published. In addition, presentations have been conducted and Demon- stration Project displays have been exhibited in the area. The USD A demonstration project continues to provide the I&E component for this project. Weekly university articles are produced on the demonstration project. Project information is disseminated through university and producer conferences. Presentations on the project are made to the public through local and regional outlets, such as the American Association of Retired Persons, Future Farmers of America, and primary and secondary education institutions. In addition, a public information workshop is held annually within the project area for project participants, cooperators, and interested individuals. Informa- tion has been disseminated through local and regional television and radio programs and newspaper articles. Presentations also have been made to local and regional agricultural producers, local irrigation districts and canal compa- nies, industry representatives, and industry supply vendors. Cooperating farm operations performing improved management practices for water quality are marked by project display boards to maximize exposure to the local population. These operations are also visited and presented during the numerous project organized field trips for targeted audiences. 56 ------- Eastern Snake River Plain, Idaho NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description The NFS control strategy focuses on nitrogen, pesticide, and irrigation water management practices that will reduce the amount of nutrients and pesticides in surface water and the amount leached into the ground water. Fertilizer evaluations and recommendations based on soil tests, petiole analysis, crop growth stage, crop type, rotation, and water sampling will be adopted. Farmers will be asked to incorporate pesticide management strategies into their farming practices. It is hoped that these strategies will reduce farm input and overuse of pesticides. Integrated Pest Management will be utilized and will include, but not be limited to, scouting, trapping, and rotational management. An irrigation management program will be implemented for each participating farm in the Demonstration Project. Recommended activities include changes in irrigation scheduling, tailwater management, repair of existing structural com- ponents, and conversion to other types of systems. Modifications Since Project Started Farmstead Assessment System and Homestead Assessment System (Farm*A*Syst/Home*A*Syst), a well-head protection program, have been added to the project. These programs will aid in ground water risk assessment for the rural homeowner. Progress Toward Meeting Goals Twenty-seven of the projected thirty local agricultural producers have cooper- ated in installation of planned NFS control strategies. Of these twenty-seven, sixteen focused on the installation of structural irrigation water application systems and nutrient management, and eleven focused on irrigation, nutrient, and pesticide management. WATER QUALITY MONITORING Design The 319 National Monitoring portion of the Demonstration Project incorpo- rates two field networks consisting of 24 constructed wells, eight of which are centrally located "permanent" wells and four are peripheral "temporary" wells, installed on both fields (Figure 7). Modifications Since Project Started The scope of work has been increased to evaluate spacial variability within the two paired fields. In addition to monthly ground water sample collection, a statistically designed soil water sampling program has been initiated. Soil water samples, using a suction lysimeter (soil water samplers), will be collected during the growing season at both the "M" and "F"paired fields. The soil water sampling program will be important in the interpretation of the ground water samples collected from in-field monitoring wells. 57 ------- Eastern Snake River Plain, Idaho • Soil samples have been collected and analyzed to determine particle size distribution. Using geostatistics, a soil texture probability map was gener- ated that predicts soil texture within the test fields. This information was used to determine the location of the installed suction lysimeters in the paired fields. • Saturated hydraulic conductivity within the paired fields will be measured. Geostatistics will be used to evaluate the spacial distribution of saturated hydraulic conductivity measurements for both test fields based on meas- ured field values. Since saturated hydraulic conductivity will vary depend- ing on the type of tillage and the amount of time that has occurred since the tillage, hydraulic conductivity measurements will be collected and the data will be analyzed, using geostatistics, over time. • Soil samp les will be collected at the surface immediately following fertilizer applications and analyzed for nitrate nitrogen. The nitrate data will be used, in conjunction with a geostatistics program, to generate the spatial distribution of the nitrate concentration for both the "M" and "F" fields. Because nitrate is mobile, the concentration of nitrate will vary over space and time. To account for the changes over time, soil samples will be taken monthly and analyzed for nitrate. This information will analyzed using geostatistics to account for nitrate concentrations in both space and time. Progress Toward Meeting Goals The project continues to collect baseline ground water quality data. Data is being compiled and stored in STORET and the USD A Water Quality Project's Central Data Base. Variables Measured Chemical and Other Nitrate (NOa-N) pH Temperature Conductivity Dissolved oxygen (DO) Total dissolved solids (TDS) on a monthly basis Total Kjeldahl nitrogen (TKN) and Ammonium (NH4-N) on a quarterly basis Organic scans for pesticide on a semi-annual basis Explanatory Variables Precipitation Crop Soil texture Nutrient content of the irrigation water Sampling Scheme Paired Field Networks Type: Grab Frequency and season: Monthly, third week of each month starting April, 1992. A number of explanatory variable monitoring activities are being undertaken by some of the other agencies participating in the project. Variables to be consid- ered in this project include precipitation, crop, soil texture, and nutrient content of the irrigation water. In addition, vadose zone suction lysimeters are being used to monitor nitrate transport.

OTHER PERTINENT INFORMATION The Eastern Snake River Plain Demonstration Project is led by the USDA Soil Conservation Service, the University of Idaho Cooperative Extension Service, and the Agricultural Stabilization and Conservation Service. In addition to the three lead agencies, this project involves an extensive state and federal inter- agency cooperative effort. Numerous agencies, including the Idaho Division of Environmental Quality, the University of Idaho Water Resource Research Institute, the USDA Agricultural Research Service, the Idaho Department of 59 ------- Eastern Snake River Plain, Idaho Water Resources, U.S. Geological Survey, and Idaho Department of Agricul- ture, have taken on various project tasks. The Idaho Department of Environmental Quality and the Idaho Water Re- source Research Institute will be responsible for the 319 National Monitoring Program portion of the project. An institutional advantage of this project is that the Soil Conservation Service and the Cooperative Extension Service are both located in the same office. Also, three local Soil and Water Conservation Districts, East Cassia, West Cassia and Minidoka, as well as the Minidoka and Cassia County ASCS, county committees and the Cassia County Farm Bureau make up the Project State Committee. The success of the USD A Demonstration Project requires the cooperation and support of a number of federal, state, and local agencies working in the project area. These various agencies come to the project bringing different back- grounds, but will be working to achieve central project objectives and goals.

The 7,000-acre watershed (Blue Creek Water- shed) that drains into Lake Pittsfield is agricultural. Agricultural production consists primarily of row crops (corn and soybeans). Small livestock operations consist of hog production, generally on open lots, and some cattle on pasture. Sedimentation is the major water quality problem in Lake Pittsfield. Sediment from farming operations, gullies, and shoreline erosion has decreased the capacity of Lake Pittsfield from 262 acres to 200 acres (a 25% reduction) in the last 33 years. Other water qualityproblems are excessive nutrients and atrazine contamination. The lake is classified as hypereutrophic, a process caused by excess nutrients. The major land treatment strategy is to reduce sediment transport into Lake Pittsfield by constructing settling basins throughout the watershed, including a large basin at the upper end of Lake Pittsfield. Water Quality Incentive Project (WQIP) money, provided through the Agricultural Stabilization and Conserva- tion Service (ASCS), will be used to fund conservation tillage, integrated crop management, livestock exclusion, filter strips, and wildlife habitat management. An information and education program on the implementation of all of the BMPs, used to control sediment, fertilizer, and pesticides, will be conducted by the Pike County Soil and Water Conservation District (SWCD). The Illinois State Water Survey (ISWS) is conducting the Blue Creek Water- shed water quality monitoring program in order to evaluate the effectiveness of the settling basins. Water quality monitoring consists of storm event tributary sampling, lake water quality monitoring, and lake sedimentation rate monitor- ing. Land-based data are being used by the ISWS to develop watershed maps of sediment sources and sediment yields using a geographical information system (GIS). The data for the different GIS layers consist of streams, land uses, soils, lake boundary, sub-watersheds, topography, and roads. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments Lake Pittsfield is a 200-acre lake located near the city of Pittsfield in Pike County (western Illinois) (Figure 8). Lake Pittsfield serves as the primary drinking water resource for the city of Pittsfield. Secondarily, the lake is used for recreational purposes (fishing and swimming). Decreased storage capacityin Lake Pittsfield, caused by excessive sedimentation, is the primary water quality impairment. Lake eutrophication 65 ------- Lake Pittsfiplri Illinnk and occasional concentrations of atrazine above the 3 ppb Maximum Contami- nant Level (MCL) also impair lake uses. Pre-Project Water Quality Lake sedimentation studies have been conducted four times: in 1974, 1979, 1985,-and 1992. Almost 15% of Lake Pittsfield's volume was lost in its first 13 years (see table below). An additional 10% of the lake's volume was lost in the next 18 years (1974 to 1992), suggesting that the rate of sedimentation has slowed. The majority of the lake volume that has been lost is at the Blue Creek inlet into the lake, which is in the upper north portion of the lake. Lake Pittsfield Sedimentation Studies.

In 1993, Lake Pittsfield's water quality was found to exceed Illinois Pollution Control Board's general use water quality standards for total phosphorus (0.05 mg/1). Orthophosphorus standards of 0.05 mg/1 were exceeded in 70% of the samples. The 0.3 mg/1 standard for inorganic nitrogen was exceeded in 60% of the water samples. Water quality samples collected in 1979 had similarly excessive amounts of phosphorus and nitrogen, as did the 1993 samples. The objectives of the project are to: • reduce sediment loads into Lake Pittsfield and • evaluate the effectiveness of sediment retention basins. March 1,1993 - February 28, 1995 (Watershed) September 1,1992 - 1994 (Monitoring Strategy) Note: Money for monitoring is approved yearly. Contingent upon funding, monitoring should be continued for at least four years past installation of sediment retention basins. Initial funding in 1992 as a 319 Watershed Project. Currently pending approval as a 319 National Monitoring Program project. 66 ------- Lake Pittsfield, Illinois PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorologic Factors Land Use The 7,000-acre Blue Creek watershed that drains into Lake Pittsfield is located in western Illinois (Figure 8). The terrain is rolling with many narrow forested draws in the lower portion of the watershed. The topography of the watershed's upper portion is more gentle and the draws are generally grassed. The area surrounding Lake Pittsfield receives approximately 39.5 inches of rainfall per year, most of which falls in the spring, summer, and early fall. Soils are primarily loess derived. Soils in the upper portion of the watershed devel- oped under prairie vegetation, while those in the middle and lower portions of the watershed were developed under forest vegetation. Some sediment-reducing BMPs are currently being used by area farmers as a result of a program (Special Water Quality Project) that was started in 1979. Pike County SWCD personnel encouraged the use of terraces, no-till cultiva- tion, contour plowing, and water control structures. Many terraces were con- structed and most farmers adopted contour plowing. However, greater adoption of no-till and other soil conserving BMPs is still needed.

Currently, farmers are being surveyed about their attitudes on water quality. This survey is being conducted by University of Illinois Extension personnel. 67 ------- LakePittsfield. Illinois NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description The nonpoint source control strategy is based on reducing sediment movement off-site and limiting the transport of sediment into the water resource, Lake Pittsfield. Section 319 funds will be used to build between 25 and 35 small (approximately two acres each) sediment retention basins. These basins will be used to limit the transport of sediment into Lake Pittsfield. In addition, a larger basin, capable of trapping 90% of the sediment entering Lake Pittsfield at the upper end, will be constructed with 319 funds. Funds from the ASCS's WQIP will be used to encourage the adoption of BMPs that will reduce the movement off-site of sediment, fertilizer, and pesticides. These BMPs include conservation tillage, integrated crop management, live- stock exclusion, filter strips, and wildlife habitat management. In order to reduce shoreline erosion, shoreline stabilization BMPs will be implemented using Section 314 funds. Old rip rap will be repaired, and new rip rap will be installed along the shoreline. WATER QUALITY MONITORING Design Variables Measured Storm sampling at four stations on the main channel into Lake Pittsfield (Blue Creek), and three stations at major ravines to Blue Creek (Figure 9). Trend monitoring during baseflow of Blue Creek at one station. Trend monitoring at the three stations located in Lake Pittsfield. Lake sedimentation studies conducted prior to and after dredging.

These stations are equipped with ISCO automatic samplers and manual DH-59 depth-integrated samplers. A pressure transducer triggers sampling as the stream rises. The samplers measure stream height. In addition, the streams are checked manually with a gage during flood events to determine the stage of the stream. During these flood events, the stream is rated to determine flow in cubic feet per second. Stream stage is then correlated with flow in order to construct a stream discharge curve. Water samples are analyzed to determine sediment loads. Three stations located on tributaries either into Blue Creek or Lake Pittsfield (stations E, F, and I - see Figure 9) are also being monitored during storm events. These stations are equipped with ISCO automatic samplers. Gaging of these stations will be conducted for at least four years. ,- Base stream flow is sampled monthly on Blue Creek at Site C (see Figure 9). Three lake sampling stations are being established to reflect the most shallow portion of the lake, a middle lake depth, and the deepest part ofthe lake. Water quality grab samples are taken monthly from April through October. Three variables are measured at two feet depth intervals: secchi disk transpar- ency, water temperature, and dissolved oxygen. In addition, water chemistry samples are taken from the surface of all three lake stations, as well as the lowest depth at the deepest station, and analyzed for the chemical constituents listed above (see Chemical and Other Variables Meas- ured). Rain gages will be placed near sampling sites C, D, and H (see Figure 9). The water quality monitoring data will be entered into a database and then loaded into the USEPA (U.S. Environmental Protection Agency) water quality data base, STORET. Data will also be stored and analyzed with the USEPA NonPoint Source Management System (NPSMS) software.. 69 ------- Lake Pittsfield, Illinois TOTAL PROJECT BUDGET Project Element Proj Mgt I&E LT(319) WQ Monit Cultural Practices (WQIP) Dredge/Shoreline/ Aeration (314) TOTALS Federal NA NA 620,100 235,000 32,000 132,110 1,019,210 Funding Source ($) State NA NA NA NA NA Local NA NA NA NA NA NA 904,000 NA 904,000 Sum NA NA 620,100 235,000 32,000 1,036,110 1,923,210 Source: State of Illinois, 1993; State of Illinois, 1992 IMPACT OF OTHER FEDERAL AND STATE PROGRAMS In 1979, the Pike County SWCD began a Special Water Quality Project that encouraged the implementation of terraces, no-till cultivation, contour plow- ing, and water control structures. This project was instrumental, along with drier weather conditions, in reducing soil erosion from an average of 5.8 tons per acre to 3.3 tons per acre (a 45% decrease). In addition to the sediment-reducing shoreline BMPs, Section 314 funds will also be used to install three destratifiers (aerators) in Lake Pittsfield to increase oxygen concentrations throughout the lake, thereby increasing fish habitat. The lake will be dredged in 1995 to reclaim the original capacity of the lake.

The project areas include Sny Magill Creek and North Cedar Creek basins (henceforth referred to as the Sny Magill watershed) (Figure 10). Sny Magill and North Cedar creeks are Class "B" cold water streams located in northeastern Iowa. North Cedar Creek is a tributary of Sny Magill Creek. The creeks are managed for "put and take" trout fishing by the Iowa Department of Natural Resources (IDNR) and are two of the more widely used streams for recreational fishing in the state. Sny Magill Creek drains a 22,780-acre watershed directly into the Upper Mis- sissippi River Wildlife and Fish Refuge and part of Effigy Mounds National Monument. The refuge consists of islands, backwaters, and wetlands of the Mississippi River. These backwaters are heavily used for fishing and also serve as an important nursery area for juvenile and young largemouth bass. The entire Sny Magill watershed is agricultural, with no industry or urban areas. There are no significant point sources of pollution in the watershed. Land use consists primarily of row crop (for cropland) (26%), cover crop, pasture (24%), forest, forested pasture (49%), farmstead (1%). Half of the cropland is in corn, with the rest primarily in oats and alfalfa in rotation with corn. Row crop acreage planted to corn has increased substantially over the past 20 years. There are about 140 producers in the watershed, with farm sizes averaging 275 acres. Animals in the watershed include dairy cattle, beef cattle, and hogs. Water quality problems result primarily from agricultural nonpoint source (NFS) pollution; sediment is the primary pollutant. Nutrients, pesticides, and animal waste are also of concern. The USD A land treatment projects being implemented in the watershed are the Sny Magill Hydrologic Unit Area (HUA) project and the North Cedar Creek Agricultural Conservation Program (ACP) - Water Quality Special Project (WQSP). The purpose of the two projects is to provide technical assistance, cost sharing, and educational programs to assist agricultural producers in the water- shed to implement voluntary changes in farm management practices that will result in improved water quality in Sny Magill Creek. Sediment control meas- ures, water and sediment control basins, animal waste management systems, stream corridor management improvements, bank stabilization, and buffer strip demonstrations around sinkholes will be utilized to reduce agricultural NPS pollution. A long-term goal of a 50% reduction in sediment delivery to Sny Magill Creek has been established. The land treatment projects are also focus- ing on nutrient and pesticide management to reduce nitrogen, phosphorus, and pesticide loading. 75 ------- Sny Maglll Watershed, Iowa A paired watershed approach is being used with the Bloody Run Creek water- shed (adjacent to the north and draining 24,064 acres) serving as the compari- son watershed (Figure 11). Weekly nitrate samples collected between February and December 1991 by the IDNR indicate that the two watersheds respond similarly to precipitation events in terms of nitrate concentrations. However, the large size of the two watersheds will create significant challenges in carrying out a true paired watershed study. Land treatment and land use changes will have to be kept to a minimum in the Bloody Run Creek watershed throughout the project period and for the first two years of water quality monitoring in the Sny Magill watershed. Subbasins within the Sny Magill watershed will be compared using up- stream/downstream stations. Primary monitoring sites, equipped with U.S. Geological Survey (USGS) stream gages to measure discharge and suspended sediment, have been estab- lished on both SnyMagill and Bloody Run creeks. The primary sites and several other sites on both creeks will be sampled for chemical and physical water quality variables on a weekly to monthly basis. An annual habitat assessment will be conducted along stretches of both stream corridors. Biomonitoring of macroinvertebrates will occur on a bimonthly basis and an annual fisheries survey will be conducted. Coordination of land treatment and water quality data collection, management, and analysis among the many participating agencies is being handled by the IDNR - Geological Survey Bureau (IDNR-GSB) in an effort to maximize the probability of documenting linkage between land treatment and water quality improvements. To the extent practicable, the agencies will coordinate land treatment application with water quality monitoring to focus implementation in particular subbasins, attempting to maintain other subbasins in an unaltered state for a longer period of time for comparison. This profile is based primarily on information contained in the project work plan (Seigleyetal., 1992). PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments Sny Magill and North Cedar creeks are Class "B" cold water streams located in northeastern Iowa. SnyMagill and North Cedar creeks are managed for "put and take"trout fishing by the IDNR and are two of the more widely used streams for recreational fishing in Iowa. SnyMagill Creek ranks ninth in the state for angler usage. The SnyMagill watershed drains an area of 35.6 square miles directly into the Upper Mississippi River Wildlife and Fish Refuge. The refuge consists of islands, backwaters, and wetlands of the Mississippi River. The creek also drains into part of Effigy Mounds National Monument. These backwaters are 76 ------- Sny Maglll Watershed, Iowa heavily used for fishing and also serve as an important nursery area for juvenile and young largemouth bass. The creeks are further designated as "high quality waters" to be protected against degradation of water quality. Only 17 streams in the state have received this special designation. The state's Nonpoint Source Assessment Report indi- cates that the present classifications of the creeks as protected for wildlife, fish, and semi-aquatic life and secondary aquatic usage are only partially supported. The report cites impairment of the creeks'water qualityprimarilybynonpoint agricultural pollutants, particularly sediment, animal wastes, nutrients, and pesticides. There are no significant point sources of pollution within the Sny Magill watershed. Sediment delivered to the creek includes contributions from excessive sheet and rill erosion on approximately 4,700 acres of cropland and 1,600 acres of pasture and forest land in the watershed. Gully erosion problems have been identified at nearly 60 locations. There are more than 30 locations where livestock facilities need improved runoff control and manure management systems to control solid and liquid animal wastes. Grazing management is needed to control sediment and animal waste runoff from over 750 acres of pasture and an additional 880 acres of grazed woodland. Pre-Project Water Quality Streambank erosion has contributed to significant sedimentation in the creek(s). Improved stream corridor management, to keep cattle out of the stream and repair riparian vegetation, is needed in critical areas to mitigate animal waste and nutrient problems and improve bank stability. Water quality evaluations conducted by the University Hygienic Laboratory (UHL) in 1976 and 1978 during summer low-flow periods in Sny Magill and Bloody Run creeks showed elevated water temperatures and fecal coliform levels (from animal wastes) in Sny Magill Creek. Downstream declines in nutrients were related to algal growth and in-stream consumption. An inventory of macroinvertebrate communities was included from several reaches of the streams (Seigley et al., 1992). Assessments in North Cedar Creek during the 1980s by IDNR and the USD A Soil Conservation Service (SCS) located areas where sediment is covering the gravel and bedrock substrate of the streams, lessening the depth of existing pools, increasing turbidity, and degrading aquatic habitat. Animal waste de- composition increases biochemical oxygen demand (BOD) in the streams to levels that are unsuitable for trout survival at times of high water temperature and low stream flows. The IDNR has identified these as the most limiting factors contributing to the failure of brook trout to establish a viable population (Seigley etal., 1992). Project staff are currently preparing a summary of pre-project water quality studies mentioned above plus baseline data collected during the summer of 1991. A paper on sedimentation rates and analysis of STORET data from surrounding tributaries will also be included in the report. 77 ------- Sny Magill Watershed, Iowa Current Water Quality Objectives Modifications Since Project Initiation Project Time Frame Project Approval Project objectives include the following: • To quantitatively document the significance of water quality improvements resulting from the implementation of the Sny Magill HUA Project and North Cedar Creek WQSP; • To develop the protocols and procedures for a collaborative interagency program to fulfill the U.S. Environmental Protection Agency (USEPA) standards for Nonpoint Source Monitoring and Reporting Requirements for Watershed Implementation Projects; • To refine monitoring protocols to define water quality impacts and the effectiveness of particular management practices; • To develop Iowa's capacity for utilization of rapid habitat and biologic monitoring; • To use the water quality and habitat monitoring data interactively with implementation programs to aid targeting, and for public education to expand awareness of the need for NFS pollution prevention by farmers; and • To provide Iowa and the U SEP A with needed documentation for measures of success of NPS control implementation (Seigley et al., 1992). Specific quantitative water quality goals need to be developed that are directly related to the water quality impairment and the primary pollutants being ad- dressed by the land treatment implemented through the USD A projects. None. 1991 -unknown (approximately 10 years, if funding allows) 1992 PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorologic Factors The watershed drains an area of 22,780 acres directly into the Upper Mississippi River Wildlife and Fish Refuge and part of Effigy Mounds National Monument. Average yearly rainfall in the area is 33 inches. The creeks are marked by high proportions (70-80% or more of annual flow) of ground water base flow, which provides their cold water characteristics. Hence, ground water quality is also important in the overall water resource manage- ment considerations for area streams. The watershed is characterized by narrow, gently sloping uplands that break into steep slopes with abundant rock outcrops. Up to 550 feet of relief occurs across the watershed. The landscape is mantled with approximately 10-20 feet of loess, overlying thin remnants of glacial till on upland interfluves, which in turn overlie Paleozoic-age bedrock formations. The bedrock over much of the area is Ordovician Galena Group rocks, which compose the Galena aquifer, an 78 ------- Sny Magill Watershed, Iowa important source of ground water and drinking water in the area. Some sink- holes and small springs have developed in the Ordovician-age limestone and dolomite. The stream bottom of Sny Magill and its tributaries is primarily rock and gravel with frequent riffle areas. Along the lower reach of the creek where the gradient is less steep, the stream bottom is generally silty. The upstream areas have been degraded by sediment deposition. Land Use The entire watershed is agricultural, with no industry or urban areas. There are no significant point sources in the watershed. Half of the cropland is corn, with the rest primarily in oats and alfalfa in rotation with corn. There are about 140 producers in the watershed, with farm sizes averaging 275 acres. Land use is variable on the alluvial plain of Sny Magill Creek, ranging from row cropped areas, to pasture and forest, to areas with an improved riparian right-of-way where the IDNR owns and manages the land in the immediate stream corridor. The IDNR owns approximately 1,800 acres of stream corridor along approximately eight miles of the length of Sny Magill and North Cedar creeks. Some of the land within the corridor is used for pasture and cropping through management contracts with the IDNR. Row crop acreage planted to corn has increased substantially over the past 20 years. Land use changes in the watershed have paralleled the changes elsewhere in Clayton County, with increases in row crop acreage, fertilizer and chemical use, and attendant increases in erosion and runoff and nutrient concentrations. Forest Service data show a four percent decline in woodland between 1974 and 1982. Much of this conversion to more erosive row crop acreage occurred without adequate installation of soil conservation practices.

Iowa INFORMATION, EDUCATION, AND PUBLICITY Progress Toward Meeting Goals Information and education efforts in the watershed will focus on the following: • Demonstration and education efforts in improved alfalfa haymanagement (to reduce runoff potential on hayland and increase profitability and acreage ofhayproduction); • Improved crop rotation management and manure management (to reduce fertilizer and chemical use); • Implementation of the Farmstead Assessment System [SCS, Iowa State University Extension (ISUE)]; • Woodland management programs (to enhance pollution-prevention ef- forts on marginal cropland, steep slopes, riparian corridors, and buffer areas in sinkhole basins); and • Intensive Integrated Crop Management (ICM) assistance services to pro- ducers in the watershed (ISUE). Information will also be disseminated through newsletters, field days, special meetings, press/media releases, and surveys of watershed project participants. Additional resources for technical assistance and educational programs will be provided in the area through the Northeast Iowa Demonstration Project, di- rected by ISUE, and the Big Spring Basin Demonstration Project, directed by IDNR. Through FFY93, the following have been completed in Sny Magill and North Cedar Creek watersheds: various management plots, including manure, nitrogen, tillage, and weed, have been maintained for demonstration and educational purposes in the watershed area; numerous field days were held at plot sites, and the plots were designed to be toured on a self-guided basis; Water Watch, a bi-monthly newsletter for the area, included relevant arti- cles on farmstead assessment, ICM, nutrient management of manure, etc.; a series of articles on wellhead protection was printed in local newspapers; a baseline survey of farming practices for farm operators in the Sny Magill Creek area was completed during the winter of 1992; and ICM plans were developed for 44% of cropland in the project area through one-on-one meetings with farmers. NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description The project is intimately connected to two ongoing land treatment projects in the watershed: the Sny Magill Hydrologic Unit Area project and the North Cedar Creek Agricultural Conservation Program - Water Quality Special Pro- ject. The HUA Project is a five-year project begun in 1991 and covering 19,560 80 ------- Sny Magill Watershed, Iowa acres (86%) of the Sny Magill watershed. The remainder of the watershed is included in the WQSP, which began in 1988. The purpose of the projects is to provide technical and cost sharing assistance and educational programs to assist farmers in the watershed in implementing voluntary changes in farm manage- ment practices that will result in improved water quality in Sny Magill Creek. No special critical areas have been defined for the HUA Project. Highly credible land has been defined and an attempt is being made to treat all farms, prioritizing fields within each farm to be treated first. Structural practices, such as terracing and a few animal waste systems, are being implemented. Extension staff are assisting farmers with farmstead assessment and with ICM, in the hope of reducing fertilizer and pesticide inputs by at least 25% while maintaining production levels. The WQSP is essentially completed. Remaining funded projects will be com- plete in 1994. Practices implemented were structural (primarily terraces). No ICM or other .information and education programs were implemented. Farmer participation was 80-85%. Data on actual acreage treated are being compiled. The long-term sediment delivery reduction goal for Sny Magill Creek is 50%. Fertilizer and pesticide inputs are expected to be reduced by more than 25%.

SCS is utilizing the "CAMPS" data- base to record annual progress for land treatment and may link this to a geographic information system (GIS), as well. ISUE will conduct baseline farm 82 ------- Sny Magill Watershed, Iowa management surveys and attitude surveys among watershed farmers and wJJJ also have implementation data from ICM - Crop System records. IDNR-GSB will transfer the annual implementation records to the project GIS, ARC/INFO, to provide the necessary spatial comparisons with the water quality monitoring stations. Participating agencies will meet in work groups as needed, typically on a quarterly basis, to review and coordinate needs and problems. Monitoring results will be reviewed annually by an interagency coordinating committee to assess needed changes. Modifications Since Project Started Progress Toward Meeting Goals None. Through FFY93, the following have been completed in Sny Magill and North Cedar Creek watersheds: • 216,775 feet of terraces • nitrogen, phosphorous, and pesticide management on 3,428 acres • 88 grade stabilization structures installed • 21 water and sediment control basins installed • well testing of 169 private wells • 2 agricultural waste structures installed ISUE conducted baseline survey of farming practices for farm operators in the Sny Magill Creek area in the winter of 1992. A mid-project survey of the farm operators will be completed in the summer of 1994 as will an initial survey of farm operators in the Bloody Creek area ("control" watershed). Linkage of SCS "CAMPS" database to IDNR-GSB GIS has been completed. WATER QUALITY MONITORING Design The Sny Magill watershed is amenable to documentation of water quality responses to land treatment. The cold water stream has a high ground water baseflow which provides year-round discharge, minimizing potential missing data problems. These conditions also make possible analysis of both runoff and ground water contributions to the water quality conditions. Because of the intimate linkage of ground and surface water in the region, the watershed has a very responsive hydrologic system and should be relatively sensitive to the changes induced through the implementation programs. A paired watershed study is planned to compare Sny Magill watershed to the (control) Bloody Run Creek watershed (adjacent to the north and draining 22,064 acres). Watershed size, ground water hydrogeology, and surface hydrol- ogy are similar; both watersheds receive baseflow from the Ordovician Galena aquifer. The watersheds share surface and ground water divides and their proximity to one another minimizes rainfall variation. However, the large size 83 ------- Snv Maqil! Watershed. Iowa of the two watersheds will create significant challenges in conducting a true paired watershed study. Land treatment and land use changes will have to be kept to a minimum in the Bloody Run Creek watershed throughout the project period and for the first two years of water quality monitoring in the Sny Magill watershed. Within the Sny Magill watershed, subbasins will be compared using up- stream/downstream stations. Modifications Since Project Started None.

The sites are equipped with USGS stream gages to provide continuous stage measurements and daily discharge measurements. Suspended sediment samples are collected daily by local observers and weekly by water quality monitoring personnel when a significant rainfall event has occurred. Monthly measurement of stream discharge will be made at seven supplemental sites (NCC, SN2, SNT, SNWF, SN3, BRSC, and BR2). Baseline data were collected duringthe summer of 1991. A report documenting these data will be published in 1994. The monitoring program as described below began in October of 1991. Weekly grab sampling is being conducted at the primary surface water sites (SN1, BR1) for fecal coliform bacteria, N-series (NOs + NOa-N, NH4-N, Organic-N) anions, TP, BOD, and immunoassay for triazine herbicides. ------- Sny Magill Watershed, Iowa Four secondary sites are being monitored weekly (three on Sny Magi]]; SN3, SNWF, and NCC; and one on Bloody Run: BR2).* Grab sampling will be conducted for fecal coliform, partial N-series (NOs + NOa-N, NEU-N), and anions. A Weekly samp ling will be conducted by the USNPS (weeks 1 and 3) and IDNR- G SB (weeks 2,4, and 5). Three additional sites are being monitored on a monthly basis (two on Sny Magill: SN2, SNT; and.one on Bloody Run: BRSC).* These are grab sampled for fecal coliform, partial N-series, and anions. Temperature, conductivity, dissolved oxygen, and turbidity are measured at all sites when sampling occurs. An annual habitat assessment will be conducted along stretches of stream corridor, biomonitoring of macroinvertebrates will occur on a bi-monthly basis, and an annual fisheries survey will be conducted. * Note: Originally, site BRSC was monitored weekly and site BR2 was moni- tored monthly. However, after one water-year of sampling, the invertebrate biomonitoring group requested (in March of 1992) that the sites be switched. Thus, since October 1, 1992, BRSC has been monitored monthly and BR2 has been monitored weekly. Modifications Since Project Started None. Water Quality Data Management and Analysis Data Management Data management and reporting will be handled by the IDNR - GSB and will follow the Nonpoint Source Monitoring and Reporting Requirements for Wa- tershed Implementation Grants. USEPA Nonpoint Source Management System (NPSMS) software will be used to track and report data to USEPA using their four information "files": the Waterbody System File, the NPS Management File, the Monitoring Plan File, and the Annual Report File. All water quality data will be entered in STORET. Biological monitoring data will be entered into BIOS. All U.S. Geological Survey (USGS) data will be en- tered in WATSTORE, the USGS national database. Data transfer processes are already established between USGS, UHL, and IDNR-GSB. Coordination will also be established with SCS and ISUE for re- porting on implementation progress. Data Analysis For annual reports, data will be evaluated and summarized on a water-year basis; monthly and seasonal summaries will be presented, as well. Statistical analysis and comparisons will be performed as warranted using rec- ommended SAS packages and other methods for statistical significance and time-series analysis. 85 Iowa Department of Natural Resources. 1994.

Land use in the 830-acre watershed is almost exclusively agricultural, consisting of beef and dairy production and associated activities. Agricultural activities related to dairy production are believed to be the major nonpoint source of pollutants to the small stream draining the watershed. This situation is particularly apparent in one of the headwater subwatersheds, which will be compared to the other subwatershed that primarily contains beef farms. Proposed land treatment includes conversion of cropland to pasture, installa- tion of watering systems, fencing to exclude livestock from tributary streams, and the proper use of newly constructed manure slurry storage tanks. Water quality monitoring involves both paired watershed and upstream/down- stream experimental designs. Sampling will occur at the outlets of the paired watersheds (stations 1A and IB) and at the upstream/downstream stations (1C and 2A) once per week (Figure 13). Storm-event sampling by an automatic sampler will occur at station 2A. Water samples will be analyzed for sediment, nitrogen, and phosphorus. Monitoring data will be used to evaluate the suitability of a modified version of the CREAMS and/or ANSWERS model for its application in the larger Mono- cacy River basin. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments Pre-Project Water Quality Warner Creek is a small stream with a drainage area of about 830 acres, all of which are included in the study area. Its average discharge is 30 gallons per minute. The project is more of a watershed study than an implementation project; therefore, the water resource has no significant use, except for biological habitat. Seven weeks of pre-project water quality monitoring at four stations yielded the following data: Nitrate Nitrite Ammonia TKN TKP Orthophosphorus (mg/1) (mg/1) (mg/1) (mg/1) (mg/1) (mg/1) 3.3-6.7 .01-.05 0-23.0 0-73.0 Source: Shirmohammadi and Magette, 1993 0-6.7 0-3.6 91 ------- Warner Creek Watershed, Maryland Current Water Quality Objectives Project Time Frame Project Approval The objectives of the project are to: • develop and validate a hydrologic and water quality model capable of predicting the effects of agricultural best management practices (BMPs) on water quality, both at the field and basin scales; • collect water quality data for use in the validation of the basin-scale hydrologic and water quality model; • apply the validated model to illustrate relationships between agricultural BMPs and watershed water quality in support of the Monocacy River demonstration project. May, 1993-June, 1997 June, 1993 PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorologic Factors Land Use Pollutant Source(s) Approximately 830 acres. The watershed is in the Piedmont physiographic province. Geologically, bed- rock in this area has been metamorphosed. Upland soils in the watershed belong to the Penn silt loam series with an average slope of three to eight percent. Average annual rainfall near the watershed is 44-46 inches. Land use in the upper part (upstream of 1C) of the watershed is mostly pasture and cropland, with a few beef and dairy operators. The subwatershed upstream of station IB contains a dairyoperation, and a recent survey indicated that about sixty-five percent of the land was used for corn silage production. Downstream of station 1C, land use is also mostly pasture and cropland, which is used to support dairy and beef production. The major sources of pollutants are thought to be the dairy operations and the associated cropland. Pastures in which cows have unlimited access to the tributary streams also contribute significant amounts of pollutants. INFORMATION, EDUCATION, AND PUBLICITY The project will draw support from the University of Maryland Cooperative Extension Service (CES) agents, the Soil Conservation Service (SCS) District office in Frederick, Maryland, and project specialists located in the Monocacy River Water Quality Demonstration office. Several of the office's personnel have already established lines of communication between watershed farmers and the local personnel of the relevant USDA agencies. Education and public awareness will be accomplished through the CES in the form of tours, press releases, scientific articles, and oral presentations. 92 ------- Warner Creek Watershed, Maryland NONPOINT SOURCE CONTROL STRATEGY AND PESIGN Description Upstream/downstream Study Area (1C and 2A): BMPs planned for this area include construction of watering systems for ani- mals, fencing animals from streams, and the proper use of newly constructed manure slurry storage tanks. Conversion of cropland to pasture is also antici- pated in this area. Paired Watershed HA and 1B^: The implementation of BMPs in the treatment (IB) paired watershed is uncer- tain; however, a concerted effort will be made to install an animal waste management system and cropland conservation practices in this watershed.

The creek has a drainage area of 67,740 acres, which includes the towns of Holt and Mason, and part of the city of Lansing. The major commodities produced in this primarily agricultural county are corn, wheat, soybeans, and some livestock. Sycamore Creek is a tributary to the Red Cedar River, which flows into the Grand River. The Grand River discharges into Lake Michigan. The major pollutants of Sycamore Creek are sediment, phosphorus, nitrogen, and agricultural pesticides. Sediment deposits are adversely affecting fish and macroinvertebrate habitat and are depleting oxygen in the water column. Syca- more Creek has been selected for monitoring, not because of any unique characteristics, but rather because it is representative of creeks throughout lower Michigan. Water quality monitoring will occur in three subwatersheds: Haines Drain, Willow Creek, and Marshall Drain (Figure 15). The Haines subwatershed, where best management practices (BMPs) have already been installed, will serve as the control and is outside the Sycamore Creek watershed. Stormflow and baseflow water quality samples from each watershed will be taken from March through July of each project year. Water will be sampled for turbidity, total suspended solids, chemical oxygen demand, nitrogen, and phosphorus. Land treatment will consist primarily of sediment-and-nutrient-reducing BMPs on cropland, pastureland, and hayland. These BMPs will be funded as part of the U.S. Department of Agriculture (USD A) Sycamore Creek Hydrologic Unit Area (HUA) project. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments Pre-Project Water Quality Sycamore Creek is a tributary of the Red Cedar River. The Red Cedar River flows into the Grand River, which flows into Lake Michigan. Sycamore Creek is protected by Michigan State Water Quality Standards for warm-water fish, body contact recreation, and navigation. Currently the pollut- ant levels in the creek are greater than prescribed standards. In particular, dissolved oxygen levels (the minimum standard level is 5 milligram per liter) are below the minimum standard, primarily because of sediment but also, in some cases, nutrients (Suppnick, 1992). The primary pollutant is sediment. Widespread aquatic habitat destruction from sedimentation has been documented. Nutrients (nitrogen and phospho- rus) are secondary pollutants. Pesticides may be polluting ground water; how- ever, evidence of contamination by pesticides is currently lacking. Low levels of dissolved oxygen in the creek are a result of excess plant growth and organic matter associated with the sediment. 99 ------- Sycamore Creek Watershed, Michigan Sediment and Phosphorus Content of Sycamore Creek Under Routine (dry) and Storm (wet) Flow Conditions: Current Water Quality Objectives Modifications Since Project Initiation Project Time Frame Project Approval DryP • mg/1 0.01-0.09 WetP mg/1 0.04-0.71 Dry Sediment mg/1 4-28 Wet Sediment mg/1 6-348 Source: SCS/CES/ASCS, 1990 A biological investigation of Sycamore Creek, conducted in 1989, revealed an impaired fish and macroinvertebrate community. Fish and macroinvertebrate numbers were low, suggesting lack of available habitat. Channelization of Sycamore Creek is causing unstable flow discharge, signifi- cant bank-slumping, and erosion at sites that have been dredged. The water quality objective is to reduce the impact of agricultural nonpoint source (NFS) pollutants on the surface and in ground water of Sycamore Creek. The goal of the project is to reduce sediment delivery into Elm Creek by 52%. None. Monitoring will be conducted for a minimum of six years, contingent upon federal funding. 1993 PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorologic Factors Land Use The project, located in southcentral Michigan, includes 67,740 acres. The geology of the watershed consists of till plains, moraines, and eskers (glacially deposited gravel and sand that form ridges 30 to 40 feet in height). The Mason Esker and associated loamy sand and sandy loam soil areas are the major ground water recharge areas for Ingham County residents. Eskers are the predominant geologic feature near the stream. These grade into moraines that are approximately one-half to one mile in width. The moraines have sandy loam textures with slopes of 6 -18%. The moraines grade into till plains. Interspersed within the area, in, depressional areas and drainageways, are organic soils. Approximately 50% of the land in this primarily agricultural watershed is used for crops, forage, and livestock. Critical areas for targeting BMPs are agricultural fields (cropland, hayland, or pasture) within one-half mile of a stream. 100 ------- Sycamore Creek Watershed, Michigan Pollutant Source(s) Modifications Since Project Started Major BMPs already implemented in the project area are pasture and hayland planting, pasture and hayland management, diversions, cover and green manure crops, critical area plantings, conservation tillage, grade stabilization structures, grassed waterways, and integrated crop management. Crop and residue cover will be recorded on a 10-acre cell basis in each of the three monitored subwatersheds.

These I&E activities have been developed and are being implemented as part of the Sycamore Creek HU A project. Activities include public awareness campaigns, conservation tours, media events such as news releases and radio shows, display set-ups, workshops, short courses, farmer-targeted newsletters, homeowner- targeted newsletters, on-farm demonstrations, meetings, and presentations. Ingham County CES will assist producers with nutrient management plans and integrated pest management. 1994 activities include: • ten on-farm demonstrations; • one watershed tour; • one watershed winter meeting; • monthly newsletters for area farmers; • one homeowners newsletters; and • twenty-five farm plans for nutrient and pesticide management. 101 ------- Sycamore Creek Watershed, Michigan NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description Modifications Since Project Started Progress Toward Meeting Goals The Sycamore Creek U.S. Environmental Protection Agency (USEPA) Section 319 National Monitoring Program project is nested within the Sycamore Creek HUA project. The nonpoint source control strategy will include: 1) identifica- tion and prioritization of significant nonpoint sources of water quality contami- nation in the watershed and 2) promotion of the adoption of BMPs that significantly reduce the affects of agriculture on surface water and ground water quality. Selection of the BMPs will depend on land use: cropland, hayland, pasture land, or urban land. BMPs for the cropland will include conservation tillage, conser- vation cropping sequence, crop residue use, pest management, nutrient man- agement, waste utilization, critical area planting, and erosion control structures. Hayland- area BMPs will consist of conservation cropping sequence, conserva- tion tillage, pest management, nutrient management, pasture/hayland manage- ment, and pasture/hayland planting. BMPs to be utilized on pastureland are conservation cropping sequence, conservation tillage, pasture/hayland manage- ment, pasture/hayland planting, fencing, waste utilization, filter strips, and critical area planting. The following practices will be eligible for ACP funding: • Permanent Vegetative Cover Establishment • Diversions • Cropland Protective Cover • Permanent Vegetative Cover on Critical Areas • Reduced Tillage • No-Till Systems • Sediment Retention Erosion or Water Control Structure • Sod Waterways • Integrated Crop Management Practice installation and the effect on water quality will be tracked using the database ADSWQ (Automatic Data System for Water Quality). The EPIC model (Erosion Productivity Index Calculator) will be interfaced with a Geo- graphical Information System (GIS), GRASS (Geographic Resources Analysis Support System), to estimate changes in edge-of-field delivery of sediment, nutrients, and pesticides and bottom of root zone delivery of nutrients and pesticides resulting from BMP implementation. None. To date, 23,000 acres have been treated with BMPs, a 5,000-acre increase from last year. 102 ------- Sycamore Creek Watershed, Michigan WATER QUALITY MONITORING Design Modifications Since Project Started Variables Measured A paired watershed design will be used to document constituent changes in Sycamore Creek. Two subwatersheds within the project, Willow Creek and Marshall Drain, will be compared to a control subwatershed, Haines Drain, that is outside the boundaries of the project (Figure 15). BMPs were installed in the Haines Drain prior to the commencement of water quality monitoring in 1990. The Willow Creek and Marshall Drain subwatersheds were selected among all subwatersheds in the Sycamore Creek watershed because they contained the most excessive sediment loads and the largest percentage of erodible land within one-quarter mile of a channel.

Streams Watershed Boundary Figure 17: Water Quality Monitoring Stations for Elm Creek (Nebraska) Watershed 108 ------- Elm Creek Watershed. Nebraska PROJECT OVERVIEW Elm Creek is located in southcentral Nebraska, near the Kansas border (Figure 16). The creek flows in a southerly direction through agricultural lands of rolling hills and gently sloping uplands. The creek has a drainage area of 35,800 acres, consisting mainly of dryland crops of wheat and sorghum and pas- ture/range lands with some areas of irrigated corn production. A primary water use of Elm Creek is recreation, particularly as a coldwater trout stream. Sedimentation, increased water temperatures caused by the increased sedimentation, and high peak flows are impairing aquatic life by destroying habitat and thus the creek's recreational use by reducing trout productivity. Land treatment for creek remediation will include non-conventional best man- agement practices (BMPs), water quality and runoff control structures, water quality land treatment, and conventional water quality management practices (see section on nonpoint source control strategy). Many of these BMPs will be funded as part ofthe U.S. Department of Agriculture (USD A) Hydrologic Unit Area (HU A) Project. Land use will be inventoried. Cropland and BMP imple- mentation will be tracked. Additionally, land treatment monitoring will include tracking land use changes based on the 40-acre grid system ofthe Agricultural Nonpoint Source (AGNPS) model. Water quality monitoring will include an upstream/downstream design as well as a single station downstream design for trend detection. Grab samples will be collected weekly from March through September to provide water quality data. Additional biological and habitat data will be collected on a seasonal basis. PROJECT DESCRIPTION Water Resource Type and Size Elm Creek flows through cropland and pasture/range into the Republican River. Flow in the creek is dominated by inflow springs. The average discharge of Elm Creek is 21.4 cubic feet per second and the drainage area is 56 square miles. Water Uses and Impairments Elm Creek is valued as a coldwater aquatic life stream, as an agricultural water supply source, and for its aesthetic appeal. It is one of only two coldwater habitat streams in southcentral Nebraska. Sedimentation, increased water temperatures, and peak flows are impairing aquatic life by destroying stream habitat ofthe macroinvertebrates and trout. These negative impacts on the stream result from farming practices that cause excessive erosion and overland water flow. 109 ------- Elm Creek Watershed, Nebraska Pre-Project Water Quality Current Water Quality Objectives Modifications Since Project Initiation Project Time Frame. Project Approval A thorough water quality analysis of Elm Creek conducted in the early 1980s indicated that the water quality of Elm Creek was very good. There was, however, short-term degradation of water quality following storm events. The coldwater habitat use assignment of Elm Creek appeared to be attainable if it was not impaired bynonpoint source (NFS) pollution, particularly sedimenta- tion and scouring of vegetation during storm events. The NFS management objective in the Elm Creek watershed is to implement appropriate and feasible NFS control measures for the protection and enhance- ment of water quality in Elm Creek. Project goals are to: • Reduce maximum summer water temperature, • Reduce instream sedimentation, • Reduce peak flows, and • Improve instream aquatic habitat. None. Monitoring will be conducted from April, 1992 through 1996. Two additional years of monitoring have been planned, contingent upon availability of funding. 1992 PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorologic Factors Land Use The project area, in southcentral Nebraska, consists of 35,800 acres of rolling hills, gently sloping up lands, and moderately steep slopes. Elm Creek, which receives 26.5 inches of rainfall per year, lies in a sub-humid ecological region. Seventy-five percent of this rainfall occurs between April and September. The average temperature is 52 degrees Fahrenheit with averages of 25 degrees in January and 79 degrees in July. The soils are derived from loess and the predominant soil types are highly erosive. Wheat and sorghum are the primary dryland crops produced. Corn is the primary irrigated crop. Range and pasture dominate the more steeply sloping lands.

INFORMATION, EDUCATION, AND PUBLICITY Progress Toward Meeting Goals Information and education (I&E) activities have been developed and are being implemented as part of the Elm Creek HUA Project. The University of Nebraska and Cooperative Extension in Webster County are in charge of I&E activities. I&E activities will include: newsletters, a NFS video, slide shows, programs, questionnaires, fact sheets, demonstration sites, field days, and meet- ings. I&E activities implemented in the Elm Creek watershed include the following: • Seven procedures have agreed to host field days and BMP demonstration plots. To encourage no-till practices, a no-till drill is available for rent at $8.00 per acre. • A videotape on no-till crop planting practices is currently being produced. • Two newsletters are currently being produced for the project. One newslet- ter is sent to all landowners and operators in the project area and includes articles on BMPs, cost share funds available, and updates on project progress and upcoming events. In addition, a quarterly project newsletter detailing relevant project activities (i.e., budget, progress, etc.) is mailed to all coop- erators. • A series of educational programs have been held to provide producers with background information to encourage the adoption of BMPs. Other pro- gram topics included: New Tools for Pasture Production, Rotational Graz- ing Tour, and a Prescribed Burn Workshop. • An Ecofarming Clinic was held where no-till drills were demonstrated. Topics of discussion for the program included: winter wheat production and weed control, diseases, cultivar selection, insect control, and soil fertility. • Eight demonstration plots exhibiting various BMPs are currently being used as an educational tool. Practices being demonstrated include: Nitrogen Management, Integrated Crop Management - Irrigated, Integrated Crop Management - Dryland, No-till Milo Production, No-till Wheat Production, Conservation Tillage Wheat Production, Cedar Revetments for Streambank Protection, and Sediment Retention Basin Restoration. • Twenty-two news stories, articles, meeting announcements and updates have been printed in local newspapers.

Long Creek is a perennial stream that serves as the primary water supply for Bessemer City, a municipality with a population of about 4,800 people (1990 est.). Agricultural activities related to crop and dairy production are believed to be the major nonpoint sources of pollutants to Long Creek. Sediment from erod- ing cropland is the major problem in the upper third of the watershed. Cur- rently, the water supply intake pool must be dredged quarterly to maintain adequate storage volume. Below the intake, Long Creek is impaired primarily by bacteria and nutrients from urban areas and animal-holding facilities. Proposed land treatment upstream of the water supply intake includes imple- menting the land use restrictions of the state water supply watershed protection law and the soil conservation provisions of the Food Security Act. Below the intake, land treatment will involve implementing a comprehensive nutrient management plan on a large dairy farm and installing fence for live- stock exclusion from a nearby tributary to Long Creek. Land treatment and land use tracking will be based on a combination of voluntary farmer record- keeping and frequent farm visits by extension personnel. Data will be stored and managed in a geographic information system (GIS) located at the county extension office. Water quality monitoring includes a single-station, before-and-after-land treat- ment design near the Bessemer City water intake (Figure 19), upstream and downstream stations above and below an unnamed tributary on Long Creek, stations upstream and downstream of a dairy farmstead on an unnamed tribu- tary to Long Creek, and monitoring stations on paired watersheds at a cropland runoff site. Continuous composite and grab samples are being collected at various sites to provide the chemical, biological, and hydrologic data needed to assess the effectiveness of the land treatment program. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments The study area encompasses approximately seven miles of Long Creek (North Carolina stream classification index# 11-129-16). Typical mean discharges at the outlet of the study area range between 10 and 45 cubic feet per second. Long Creek is the primary water supply for Bessemer City. Water quality impairments include high sediment, bacteria, and nutrient levels. The stream channel near the water supply intake in the headwaters area requires frequent dredging due to sediment deposition. The section of Long Creek from the 121 ------- Long Creek Watershed, North Carolina Pre-Project Water Quality Bessemer City water supply intake to near the watershed outlet sampling station (Figure 19) is listed as support-threatened by the North Carolina Nonpoint Source Management Program. Biological (macroinvertebrate) habitat is de- graded in this section due to the presence of fecal coliform, excessive sediment, and nutrient loading from agricultural and urban nonpoint sources. Water quality variables change with time and location along Long Creek, but generally are close to the following averages: Fecal Coliform #/100ml 2100 BOD (mg/1) TSS (mg/1) 14 TKN (mg/1) 0.35 NOs-N (mg/1) 0.41 TP (mg/1) < 0.17 Current Water Quality Objectives Modifications Since Project Initiation Project Time Frame Project Approval Note: These average values were computed from the analyses of twelve monthly grab samples taken from three locations along Long Creek. The objectives of the project are to quantify the effects of nonpoint source pollution controls on: • Bacteria, sediment, and nutrient loadings to a stream from a working dairy farm; • Sediment and nutrient loss from a field with a long history of manure application; and • Sediment loads from the water supply watershed (goal is to reduce sedi- ment yield by 60 percent). In addition, biological monitoring of streams will attempt to show improve- ments in biological habitat associated with the implementation of nonpoint source pollution controls. None.

In addition, project personnel will make many one-to-one visits to cooperating and non-cooperating farmers in the watershed to inform them of project activities and address any questions or concerns they may have. An education plan for Gaston County has been developed that includes activi- ties in the Long Creek watershed. Also, a Watershed Citizens Advisory Com- mittee has been formed to: 1) educate other watershed residents and 2) participate in citizen monitoring. The project was also presented at several state, local, and regional water conferences. The Gaston Conservation District has presented "hands-on" conservation re- source programs to 1,553 students (grades K.-8) in the eight schools within the watershed. 123 ------- Long Creek Watershed, North Carolina NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description Modifications Since Project Started Progress Toward Meeting Goals Water Supply Watershed (site H): Bessemer City has recently purchased 13 acres of cropland immediately up- stream of the intake with the intention of implementing runoff and erosion controls. Also, to comply with the North Carolina Water Supply Watershed Protection Act, strict land use requirements will be implemented on land within one-half mile of and draining to the intake; less strict requirements such as the conservation provisions of the Food Security Act will be implemented in the remainder of the watershed. Up/downstream of Dairy 1 Tributary on Long Creek (sites B and C): The control strategy will be to design and implement a comprehensive nutrient management plan on the land between the sampling stations including construc- tion of a new waste holding facility. Dairy 1 Farmstead (sites D and E): A larger waste storage structure has been constructed. After April, 1995, improved pasture management' and livestock exclusion from the unnamed tributary between sites D and E will be implemented. Paired Cropland Watersheds (sites F and G): The control strategy on the paired watersheds involves implementing improved nutrient management on the treatment watershed while continuing current nutrient management and cropping practices on the control watershed. The number and types of best management practices (BMPs) implemented will depend on voluntary farmer participation.. None. Work has begun on developing farm plans for more than 20 farms within the watershed. Twenty-five Water Quality Incentive Project (WQIP) applications have been submitted by landowners in the Long Creek Watershed. Eight plans have been prepared representing $12,942.96 of BMP installations to control NPS pollution on these sites. Water Supply Watershed (site H): A land use survey of the agricultural portion (88%) of the water supply water- shed has been completed. Upon completion of the resource inventory, the North Carolina Division of Soil and Water Conservation will develop a Water- shed Management Plan. Installation of 90% of the recommended cropland BMPs is expected to occur by the end of 1994. However, visual inspection of the watershed tributaries indicates that considerable work remains in control- ling stream channel erosion. This will be the emphasis of future NPS control efforts. Dairy 1 Farmstead (sites D and E): The Conservation District and the landowner completed the installation of a Waste Holding Pond in September, 1993. North Carolina Agriculture Cost 124 ------- Long Creek Watershed, North Carolina Share Funds were utilized for this project. In addition, an underground main and hydrant with a stationary gun for applyingwaste effluent on the pasture/hay- land areas was installed in July, 1994. A solid waste storage structure was completed in July, 1993. North Carolina Agricultural Cost Share Funds were utilized for the construction of this project. A Resource Management System Plan will be completed by October, 1994 on the Kiser Dairy Farm to control nonpoint pollution sources and enhance the natural resources.

Its primary uses are livestock water- ing, aquatic life support, and fish and wildlife support. In addition, receiving streams are used for recreation and public drinking water supply. Sampling of benthic macroinvertebrate communities indicated poor water quality at five of six sites. Other stream uses (recreation and drinking water supply) are im- paired by elevated bacteria and nutrient concentrations. Uncontrolled access of more than 220 dairy cows and heifers to each of the two watershed streams is considered to be a major source of pollutants. Pastures adjacent to streams also are thought to contribute significant amounts of non- point source (NPS) pollutants. Therefore, proposed land treatment will focus on streambank fencing to exclude livestock from streams. This will allow a natural riparian buffer to become established, which will stabilize streambanks and potentially filter pollutants from pasture runoff. Water quality monitoring will employ a paired watershed design in which the proposed NPS control is to implement livestock exclusion fencing on 100 percent of the stream miles in the treatment subwatershed (Figure 21). Grab samples will be collected every 10 days at the outlet of each paired subwatershed from April through November. Storm event, ground water, biological, and other monitoring is planned to help document the effectiveness of fencing in the treatment subwatershed. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments The study area encompasses about 2.8 and 2.7 miles of tributary streams in the treatment and control subwatersheds, respectively. One-time measurements of summer base flow documented discharges of 0.81 and 2.24 cfs at the outlets of the treatment and control subwatersheds. Sampling of benthic macroinvertebrates at three sites in each subwatershed indicated poor water quality (organic enrichment) except for the most upstream site in the treatment subwatershed. The subwatershed streams have relatively high nutrient and fecal coliform concentrations that contribute to use impair- ments of receiving waters. 133 ------- Pequea and Mill Creek Watershed, Pennsylvania Pre-Project Water Quality Current Water Quality Objectives Project Time Frame Project Approval One-time baseflow grab sampling at four and seven locations in the control and treatment subwatershed are presented in tabular form: Fecal Coliform TP OP TKN NO3+ NO2 (mg/1) (mg/1) (mg/1) (mg/1) Treatment 1,100-38,000 .06-.25 .03-. 15 .3-1.6 10-18 Control 10,000 .02-.04 .01-.03 .1-.3 4-12 The overall objective is to document the effectiveness of livestock exclusion fencing at reducing NFS pollutants in a stream. Another objective is to reduce annual total ammonia plus organic nitrogen and total phosphorus loads from the project watershed by 40 percent.

The watershed geology consists of deep well-drained silt-loam soils underlain by carbonate rock. About five percent of each subwatershed is underlain by noncarbonated rock.

The primary source of pollutants is believed to be pastured dairy cows and heifers with uncontrolled access to stream and streambanks. Approximately 260 and 220 animals are pastured in the treatment and control watersheds. It is estimated that grazing animals deposit an average of 40 pounds of nitrogen and 8 pounds of phosphorus annually per animal. Other (commercial and urban) sources of pollutants are considered insignifi- cant. 134 ------- Pequea and Mill Creek Watershed, Pennsylvania INFORMATION, EDUCATION, AND PUBLICITY The Lancaster Conservation District and the Pennsylvania Cooperative Exten- sion Service maintain active information and education (I&E) programs in the area. Also, as part of the Pequea-Mill Creeks Hydjologic Unit Area (HUA), the landowners in the watersheds will receive additional efforts. NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description The control strategy involves installing streambank fencing on 100 percent of the pasture land adjacent to the stream draining the treatment subwatershed. All of the farmers in this watershed have agreed to install fencing. A stabilizing vegetative buffer is expected to develop naturally soon after the fencing is installed.

Agricultural activity, primarily dairy farming, is the major land use in this area ofVermont. The streams in these watersheds drain into the Missisquoi River, a major tributaryof Lake Champlain. The designated uses of many of the streams in this region are impaired by agricultural NFS pollution. The pollutants responsible for the water quality impairment are nutrients, particularly phosphorus, fecal coliform bacteria, and organic matter. The source of most of the agricultural NFS pollution is the manure generated from area dairy farms,livestock activity within streams and riparian areas, and crop production. The Missisquoi River has the second largest discharge of water and contributes the greatest nonpoint source (NFS) load of phosphorus to Lake Champlain. The Lake Champlain Basin Watersheds 319 National Monitoring Program project is designed to evaluate two treatments to control the pollutants gener- ated by agricultural activities. Treatment # 1 is a system of BMPs to exclude livestock from selected critical areas of streams and to protect streambanks. Individual BMPs for treatment # 1 will include watering systems, fencing, the minimization of livestock crossing areas in streams, and the strengthening of the necessary crossing areas. Treatment # 2 will implement intensive grazing man- agement through rotation of the pastures. The water quality monitoring is a three-way paired design: there will be one control watershed and two treatment watersheds (treatment # 1 and # 2)(Fig- ure 23). The watersheds will be monitored during a two-year calibration period prior to BMP implementation. Implementation monitoring will occur for one year and post-treatment monitoring will extend for three years. Biological, chemical, and explanatory variables are being monitored during all three monitoring phases. Fish, macroinvertebrates, fecal streptococcus, fecal coliform, and E. coli bacteria are the monitored biological variables. The chemical variables monitored are total phosphorus, total kjeldahl nitrogen, total suspended solids, dissolved oxygen, conductivity, and temperature. Two ex- planatory variables, precipitation and continuous discharge, are also being monitored. Nutrients and sediment are monitored weeklyin a flow-proportional composite sample. Bacteria grab samples are collected twice weekly, with concurrent in-situ measurements of temperature, dissolved oxygen, and conductivity. Macroinvertebrate communities will be sampled annually and fish will be evalu- ated twice each year. Invertebrate and fish monitoring will also be conducted at an unimpaired reference site. 141 ------- Lake Champlain Basin Watersheds, Vermont PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments The study streams are small second- or third-order permanent streams that drain to the Missisquoi River, a major tributary of Lake Champlain. The streams are generally 10-15 feet wide at the monitoring stations. Historical stream flow data do not exist for these streams; discharge has ranged from 1-125 cubic feet per second (cfs) since May, 1993. Because of their size, the study streams themselves are subject to very limited use for agricultural purposes (livestock watering) and recreation (swimming and fishing). No historical data exist to document support or nonsupport of these or other uses. Initial project data indicate that Vermont water quality (bacteriological) criteria for body contact recreation are consistently violated in these streams. Pre-Project Water Quality Early biological data for fish and macroinvertebrates indicate moderate to severe impact by nutrients and organic matter. These particular small water- sheds were selected to represent agricultural watersheds in the Lake Champlain Basin, which often violate state water quality criteria (Clausen and Meals, 1989; Meals, 1990; Vermont RCWP Coordinating Committee, 1991) and contribute nutrient concentrations and areal loads that generally exceed average values reported from across the United States (Omernik, 1977) and in the Great Lakes Region (PLUARG, 1978). The receiving waters for these streams - the Missisquoi River and Lake Cham- plain - have very high recreational use that is being impaired by agricultural runoff (Vermont Agency of Natural Resources, 1994). The Missisquoi River is the second largest tributary to Lake Champlain in terms of discharge (mean flow = 1450 cfs) and contributes the highest annual NFS phosphorus load to Lake Champlain among the major tributary watersheds (75.1 mt/yr) (VT and NY Departments of Environmental Conservation, 1994). Lake Champlain currently fails to meet state water quality standards for phosphorus, primarily due to excessive nonpoint source loads (Vermont Agency of Natural Resources, 1994). About 66% of the NFS phosphorus load to Lake Champlain has been attributed to agricultural land (Budd and Meals, 1994). No historical physical/chemical data exist for the study streams. Early pretreat- ment monitoring data show the following ranges: E. Coli Fecal Coliform (# 7100 ml) 110-39,000 130-20,000 TP(mg/l) 0.08 - 0.50 TKN (mg/1) 0.32-1.27 Fecal Strep. 40-10,000 TSS (mg/1) 25 - 150 Current Water Quality Objectives (Note: these values represent the range observed in May- June, 1994 and do not include any observations from spring runoff or major storm events). The overall goal of the project is a quantitative assessment of the effectiveness of two livestock/grazing management practices in reducing concentrations and 142 ------- Lake Champlain Basin Watersheds, Vermont Project Time Frame Project Approval loads of nutrients, bacteria, and sediment from small agricultural watersheds. Major water quality objectives are to: 1) Document changes in sediment, nutrient, and bacteria concentrations and loads due to treatment at the water- shed outlets; and 2) Evaluate response of stream biota to treatment.

Average annual precipitation is about 41 inches; average annual temperature is about 42°F. Frost-free growing season averages 118 days. Most of the watershed soils are till soils, loamy soils of widely variable drainage characteristics.

Source: 1993 ASCS aerial photography, unverified Nonpoint sources of pollutants are from streambanks; degraded riparian zones; and dairy-related agricultural activities, such as field-spread and pasture-de- posited manure and livestock access. Some agricultural point sources such as milkhouse waste or corn silage leachate are thought to exist. INFORMATION, EDUCATION, AND PUBLICITY Pre-project activity included letters to all watershed agricultural landowners followed by small "kitchen table" meetings with farmers in each watershed. 143 ------- Lake Champlain Basin Watersheds, Vermont The purpose of these meetings was to assess landowner interest and acceptance of the project. Two articles have been published in the weekly county newspaper concerning the project. In July, 1994, a station "open-house" was held to present the project, monitoring hardware, and some early monitoring results. The project includes a Project Advisory Committee with representatives from United States Department of Agriculture-Soil Conservation Service (USDA- SCS), Extension, Vermont Dept. of Agriculture, Vermont Dept. of Environ- mental Conservation, Vermont Natural Resources Conservation Council, and others. The committee meets quarterly to reviewprogress and assist in program direction. Because the project is in the beginning of a two-year pretreatment calibration phase, information and education efforts will focus on laying the groundwork for treatment by presenting demonstrations and information concerning rota- tional grazing and livestock access control. Additional contact with farmers will occur through routine collection of agricultural management data. NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Design The project is designed to test two treatments: 1) livestock exclusion/stream- bank protection, and 2) intensive grazing management. In the first treatment watershed, work will focus on selective exclusion of livestock from the streams, improvement or elimination of heavily used stream crossings, and revegetation of streambanks. This treatment will require fencing, watering systems, minimiz- ing livestock crossing areas, and strengthening necessary crossing areas. In the second treatment watershed, intensive rotational grazing management will be implemented as a means to minimize the time spent by livestock in or near the streamcourse without complete exclusion. During the two years of pretreatment monitoring, treatment needs will be assessed, specific plans and specifications developed, and agreements with landowners pursued. It is anticipated that the project will provide 100% cost support for cooperating landowners. Agricultural management activity - both routine and treatment implementation - will be monitored by farmer record- keeping and semi-annual interviews. It is also anticipated that some work will be done as necessary on agricultural point sources if and when such pollutant sources are identified. 144 ------- Lake Champlain Basin Watersheds, Vermont WATER QUALITY MONITORING Design Variables Measured Sampling Scheme The study is based on a three-way paired watershed design, with a control watershed and one watershed for each of the two treatments to be evaluated (Figure 23). The design calls for two years ofpretreatment calibration, one year of implementation, and three years of post-treatment monitoring. Biological E. Coli bacteria Fecal Coliform bacteria Fecal Streptococcus bacteria Macroinvertebrates Fish Chemical and Other Total phosphorus (TP) Total Kjeldahl nitrogen (TKN) Total suspended solids (TSS) Dissolved oxygen (DO) Conductivity Temperature Explanatory Variables Precipitation Discharge (continuous) Automated sampling stations are located at three watershed outlets for continu- ous recording of streamflow, automatic flow-proportional sampling, and weekly composite samples for sediment and nutrients. The watersheds are as follows: WS3 is the control, WS1 is the rotational grazing (treatment # 2), and WS2 is the streambed protection (treatment l)(Figure 23). Twice-weekly grab samples for bacteria will be collected. Concurrent in-stream measurement of tempera- ture, dissolved oxygen, and conductivity will also occur at the same time that the grab samples are collected. Three precipitation gages have been installed. All monitoring systems will operate year-round. The macroinvertebrate community at each site and a fourth "background refer- ence" site will be sampled annually using a kick net/timed eifort technique. Methods and analysis will follow U.S. Environmental Protection Agency's (USEPA) Rapid Bioassessment Protocols (Protocol III). Fish will be sampled twice a year by electroshocking and evaluated according to Rapid Bioassess- ment Protocols Protocol V. Physical habitat assessments will also be performed during each sampling run. 145 ------- Lake Champlain Basin Watersheds, Vermont Water Quality Data Management and Analysis Primary data management will be done by an in-house spreadsheet system. The USEPA Nonpoint Source Management System (NPSMS) software will be used to track and report data to USEPA. Requisite data entry into STORET and BIOS has not yet been explored. Water quality data will be compiled and reported for quarterly project advisory committee meetings, including basic plots and univariate statistics. For annual reports, data will be analyzed on a water-year basis. Data analysis will be performed using both parametric and nonparametric statistical procedures in standard statistical software.

Considerable effort on agricultural NPS control is associated with this program, including funding for pollution control/prevention demonstration projects. Additionally, the state of Vermont's phosphorus management strategy calls for targeted reductions of phosphorus loads from selected subbasins of Lake Champlain. Because this 319 National Monitoring Program project contributes to two on-going projects (the Lake Champlain Basin Program and the phosphorus reduction program), it is anticipated that some support - technical assistance, funding, or other - will be actively sought from these programs. 146 ------- Lake Champlain Basin Watersheds, Vermont OTHER PERTINENT INFORMATION None.

Otter Creek drains into the Sheboygan River, which then drains into Lake Michigan. The topography of the project area is mostly level. Land use mainly consists of dairies and croplands. Otter Creek has a warmwater forage fishery and is also used for partial body contact recreation. The fish community is degraded by poor habitat, including lack of cover, disturbed streambanks, and the absence of pools. Silt and sedi- ment deposits in the streambed have also reduced habitat quality. Fecal coli- form levels frequently exceed the state standard of 400 counts per 100 ml, and dissolved oxygen often drops below 2 mg/1 during runoff events. Otter Creek delivers high concentrations of total phosphorus and fecal coliform to the Sheboygan River. These pollutants then travel to the near shore waters of Lake Michigan, which serves as a water supply and also supports recreational fisheries. Streambed sediments originating from eroding streambanks and over-grazed dairy pastures are reducing the reproductive potential for a high quality fishery with abundant forage fish. (Forage fish are non-sport fish such as chubs, dace, and sticklebacks. Sport fish are bass and trout). Recent biological monitoring shows that water quality conditions in Otter Creek are producing tolerant to very tolerant forage fish. (Tolerance is the ability of a species to tolerate or survive environmental degradation and severe environmental conditions. Tol- erant species offish persist under degraded conditions). The stream fisheries rating, which is based on the Indexof Biotic Integrity (Lyons, 1992), is verypoor to fair. The fisheries habitat evaluation (Simonson et al., 1994) for Otter Creek is fair to good. Deposits of sediment in pools have been found to be over one foot deep. Embeddedness, a measure of substrate quality, measures between 25 and 100 percent. Highly embedded streambeds, as found in pastured areas, are detrimental to macroinvertebrates and fish. Macroinvertebrate monitoring and analysis (Hilsenhoff, 1987) resulted in water quality ratings of fair to good, with better ratings in headwaters and poorer ratings near the watershed outlet. Otter Creek is further degraded by total phosphorus and fecal coliform export from dairy barnyards, pastures, cropland, and alfalfa fields. The mean concen- tration of 22 runoff events is 104 mg/1 for suspended solids and 0.39 mg/1 for total phosphorus. Levels of fecal coliform often exceed the state standard of 400 counts/100 ml. Runoff from dairy operations is causing organic enrichment, severe degradation, and cultural eutrophication of Otter Creek. Land treatment is being monitored using an ARC/INFO geographical informa- tion system (GIS) and will be updated annually. Specific pollutant source inventory methods are used to evaluate current conditions and land treatment implementation. Inventory methods include a procedure for evaluating up land sediment sources, streambank erosion, barnyard runoff, and runoff from the 151 ------- Otter Creek, Wisconsin land application of animal waste. The status of conservation contracts and extent of land treatment implementation will be evaluated at the field and farmstead levels. Land" treatment design is based on the pollutant type and the source of the pollutant. Upland soils will be treated with cropland erosion control practices to reduce sediment loss. Streambanks will be stabilized and cattle access limited by fencing. Barnyard structural practices will be installed and nutrient management practices will be used for improvements in manure-spreading operations. Critical area criteria are designed to reduce phosphorus and sediment loading to project area streams. Five of the six dairy operations in the project area were classified as critical; two of the five critical dairy operations spread enough manure so that their cropland was classified as critical. Critical areas also include steeply sloped fields (6%), land in flood plains, and areas with depth to bedrock less than 24 inches. Streambank critical areas are the 6,200 feet of streambank trampled by cattle. PROJECT DESCRIPTION Water Resource Type and Size Water Uses and Impairments Pre-Project Water Quality Current Water Quality Objectives Otter Creek is 4.2 miles long with an average gradient of .0023 ft/ft or 12.4 ft/mile (Figure 2). The project area is 11 square miles. The creek originates from a small spring-fed lake called Gerber Lake. Otter Creek is used for fishing and for secondary body contact recreation. The fishery is impaired bypoor habitat, while contact recreation is impaired by high fecal coliform counts. Both uses are also impaired by eutrophic conditions. The Otter Creek project area is part of the larger Sheboygan River watershed, identified as a priority watershed in 1985. The watershed is characterized by streambank degradation due to cattle traffic and excessive phosphorus, fecal coliform, and sediment runoff from manure spreading and livestock operations. Fisheries are impaired because of degraded aquatic habitat that limits repro- duction. Recreation is limited by degraded fisheries and highly eutrophic and organically enriched stream waters. The Otter Creek project water quality objectives are to: • Increase the numbers of intolerant fish species byimprovingthe fish habitat and water quality. • Restore the endangered fish species (striped shiner) by improving the fish habitat and water quality. • Improve the recreational uses by reducing the bacteria levels. • Reduce the loading of pollutants to the Sheboygan River and Lake Michi- gan by installation of best management practices (BMPs) in the Otter Creek watershed. • Improve the wildlife habitat by restoring riparian vegetation. 152 ------- Otter Creek. Wisconsin Project Time Frame Project Approval Spring, 1994 through Spring, 2001 July, 1993 PROJECT AREA CHARACTERISTICS Project Area Relevant Hydrologic, Geologic, and Meteorological Factors Land Use Pollutant Source(s) The Otter Creek watershed is about 11 square miles. Each of the control areas, the Meeme and Pigeon River watersheds, is about 16 square miles. Average annual precipitation is 29 inches. Fifteen inches of rain falls during the growing season between May and September. About 42 inches of snow (five inches of equivalent rain) falls during a typical winter. The topography of the watershed is nearly level. The soils are clay loams or silty clay loams that have poor infiltration and poor percolation but high fertility. Soils are glacial drift underlain by Niagara dolomite. Land Use Agricultural Forest Suburban Wetland Water Total 72 13 11 3 1 100 The current conservation status of the watershed is unknown. Source: Wisconsin Department of Natural Resources, 1993a There are five critical dairy operations that serve as important pollutant sources. Trampled streambanks and cropland and pastureland receiving dairy manure are also critical sources. INFORMATION, EDUCATION, AND PUBLICITY The information and education (I&E) activities for this watershed project will be targeted towards key audiences and potential users of the information. Different I&E activities will be employed for the diverse audiences that will be involved in the Otter Creek watershed project. Combining public and private efforts in an effective educational approach will be an important component of the I&E strategy. Details of the I&E strategy are outlined in the Sheboygan River Water Priority Watershed Project plan (Wisconsin Department of Natural Resources, 1993b). Activities for the first three years of the project are listed along with the level of effort required to complete the task. Important activities include developing a 153 ------- Otter Creek, Wisconsin watershed folder for producers in the critical area, fact sheets, tours of animal waste facilities, workshops, meetings, and youth activities. NONPOINT SOURCE CONTROL STRATEGY AND DESIGN Description Streambank erosion and cattle access practices include shoreline and stream- bank stabilization; barnyard management includes barnyard runoff manage- ment and manure storage facilities; and cropland practices include grassed waterways, reduced tillage, and nutrient and pesticide management. WATER QUALITY MONITORING Design Variables Measured Monitoring will be done at two baseline or control watersheds and at six sites in Otter Creek. Water quality monitoring designs for the Otter Creek watershed include multiple paired, above and below, and single outlet (before and after) monitoring (Figure 23).

The schedule for chemical grab sampling and biological and habitat monitoring varies by station and by year. Chemical grab sampling occurred at a time characterized as midsummer-fall for 1990 and 1994 and during spring-midsum- mer in 1991. Future plans are for spring-midsummer monitoring in 1995 and 1999 and monitoring midsummer-fall for 1998. Fisheries, macroinvertebrate, 154 ------- Otter Creek, Wisconsin Water Quality Data Management and Analysis and habitat monitoring has been scheduled for midsummer in 1990, 1994, and 1998, and for the spring of 1991, 1995, and 1999. Biological and habitat sampling will occur monthly. There are sixsampling sites on Otter Creek and one site each at the outlet of the Meeme and Pigeon River watershed. One of the sampling sites on Otter Creek is also an outlet station that serves as the site for the single station before and after monitoring site. There are two mainstem sites above and below a critical area dairy. Fisheries monitoring includes sampling fish species and frequencies. Fisheries data are summarized and interpreted based on the Index of Biotic Integrity (Lyons, 1992). Macroinvertebrate monitoring criteria includes macroinverte- brate species or genera and numbers. Macroinvertebrate data are summarized and interpreted using the Hilsenhoff Biotic Index (Hilsenhoff, 1987). Habitat variables include riparian buffer width, bank erosion, pool area, stream width to depth ratio, riffle-to-riffle or bend-to-bend rating, percent fine sediments, and cover for fish. Habitat information is rated using the fish habitat rating system established for Wisconsin streams by Simonson et al. (1994). Grab and continuous samples will be used for water chemistry monitoring. Variables to be sampled include total phosphorus, fecal coliform bacteria, dissolved oxygen, suspended sediments, and biological and habitat variables. All water chemistry data will be entered into the Wisconsin DNR data manage- ment system, WATSTORE (the U.S. Geological Survey national database), U.S. Environmental Protection Agency's Nonpoint Source Management Sys- tem software (NPSMS), and STORET.

The software tracks NFS control measure implementation with respect to the pollutants causing the water quality problem. Currently, NPSMS can accept and track the following information (USEPA, 1991): Management Area Description: • State, USEPA Region, and lead agency. • Watershed management area description (management area name, management area identification, participating agencies, area description narrative). • 305 (b) waterbodyname and identification. • Designated use support for the waterbody. • Major pollutants causing water quality problems in waterbody and relative source contributions from point, nonpoint, and background sources. Best Management Practices (BMPs) and Nonpoint Source (NFS) Pol- lution Control Measures: • Best management practices (BMP name, reporting units, indication whether the life of the practice is annual or multi-year). • Land treatment implementation goals for management area. • Pollutant source(s) causing impaired use(s) that is (are) controlled by each BMP. Each control practice must be linked directly to the control of one or more sources of pollutants causing impaired uses. Funding Information: • Annual contributions from each funding source and use of funding for each management area. Water Quality Monitoring Plan: • Choice of monitoring approach (chemical/physical or biological/habitat). • Monitoring design and monitoring station identification (paired water- sheds, up stream-downstream, reference site for biological/habitat moni- toring, single downstream station). The paired watershed approach is recommended; the single downstream station is discouraged. • Drainage area and land use for each water quality monitoring station. • Delineation of monitoring year, seasons, and monitoring program dura- tion. • Variables measured (variable name; indication if the variable is an explana- tory variable; STORET, BIOSTORET, or 305(b) WaterbodySystem code; reporting units). 163 ------- Appendix I: Minimum Reporting Requirements Quartile values for chemical/physical variables. Quartile values are estab- lished cutoffs based on historical or first-year data for each season and monitoring station. Maximum potential and reasonable attainment scores for biological moni- toring variables. Indices scores that correspond to full, threatened, and partial use supports are required. Monitoring frequency. Chemical/physical monitoring, with associated ex- planatory variables, must be performed with at least 20 evenly-spaced grab samples in each season. Fishery surveys must be performed at least one to three times per year. Benthic macroinvertebrates must be performed at least once per season, with at least one to three replicates or composites per sample. Habitat monitoring and bioassays must be performed at least once per season. Annual Reporting: • The NPSMS software is used to report annual summary information. The raw'chemical/physical and biological/habitat data are required to be en- tered into STORET and BIOSTORET, respectively. • Annual chemical/physical and explanatory variables. The frequency count for each quartile is reported for each monitoring station, season, and variable. • Annual biological/habitat and explanatory variables. The scores for each monitoring station and season are reported. • Implementation tracking in the watershed and/or subwatersheds that con- stitute the drainage areas for each monitoring station. Implementation reported corresponds to active practices in the reporting year and includes practices with a one-year life span and practices previously installed and still being maintained.

Paired watershed design - In this design, two watersheds with similar physical characteristics and, ideally, land use are monitored for one to two years to establish pollutant-runoffresponse relationships for each watershed. Following this initial calibration period, one of the watersheds receives treatment while the other (control) watershed does not. Monitoring of both watersheds continues for one to three years. This experimental design accounts for many factors that may affect the response to treatment; as a result, the treatment effect alone can be isolated.

Total kjeldahl phosphorus (TKP) - An oxidative procedure that converts organic phosphorus forms to phosphate by digestion with an acid, catalyst, and heat. Tracking- Documenting/recording the location and timing of BMP implemen- tation. Upstream/downstream design - A water quality monitoring design that utilizes two water quality monitoring sites. One station is placed directlyupstream from the area where the implementation will occur and the second is placed directly downstream from that area. Vadose zone - The part of the soil solum that is generally unsaturated. Variable - A water quality constituent (for example, total phosphorus pollutant concentration) or other measured factors (such as stream flow, rainfall). Watershed - The area of land from which rainfall (and/or snow melt) drains into a stream or other water body. Watersheds are also sometimes referred to as drainage basins. Ridges of higher ground generally form the boundaries be- tween watersheds. At these boundaries, rain falling on one side flows toward the low point of one watershed, while rain falling on the other side of the boundary flows toward the low point of a different watershed. 175 ------- ------- Appendix IV Project Documents And Other Relevant Publications 177 ------- .
