Appendices 16 ------- 11 FOREWORD The National Eutrophication Survey was initiated in 1972 in response to an Administration commitment to investigate the nation- wide threat of accelerated eutrophication to fresh water lakes and reservoirs. OBJECTIVES The Survey was designed to develop, in conjunction with state environmental agencies, information on nutrient sources, concentrations, and impact on selected freshwater lakes as a basis for formulating comprehensive and coordinated national, regional, and state management practices relating to point-source discharge reduction and non-point source pollution abatement in lake watersheds. ANALYTIC APPROACH The mathematical and statistical procedures selected for the Survey’s eutrophication analysis are based on related concepts that: a. A generalized representation or model relating sources, concentrations, and impacts can be constructed. b. By applying measurements of relevant parameters associated with lake degradation, the generalized model can be transformed into an operational representation of a lake, its drainage basin, and related nutrients. c. With such a transformation, an assessment of the potential for eutrophication control can be made. LAKE ANALYSIS In this report, the first stage of evaluation of lake and water- shed data collected from the study lake and its drainage basin is documented. The report is formatted to provide state environmental agencies with specific information for basin planning [ 3O3(e)], water quality criteria/standards review [ 5303(c)], clean lakes [ 5314(a,b)], and water quality monitoring [ 5106 and §305(b)] activities mandated by the Federal Water Pollution Control Act Amendments of 1972. ------- 111 Beyond the single lake analysis, broader based correlations between nutrient concentrations (and loading) and trophic condi- tion are being made to advance the rationale and data base for refinement of nutrient water quality criteria for the Nation’s fresh water lakes. Likewise, multivariate evaluations for the relationships between land use, nutrient export, and trophic condition, by lake class or use, are being developed to assist in the formulation of planning guidelines and policies by EPA and to augment plans implementation by the states. ACKNOWLEDGMENT The staff of the National Eutrophication Survey (Office of Research & Development, U. S. Environmental Protection Agency) expresses sincere appreciation to the Wisconsin Department of Natural Resources for professional involvement and to the Wis- consin National Guard for conduct of the tributary sampling phase of the Survey. Francis H. Schraufnagel , Acting Assistant Director, and Joseph R. Ball of the Bureau of Water Quality, and Donald R. Winter, Lake Rehabilitation Program, provided invaluable lake documentation and counsel during the Survey. Central Office and District Office per- sonnel of the Department of Natural Resources reviewed the prelim- inary reports and provided critiques most useful in the preparation of this Working Paper series. Major General James J. Lison, Jr., the Adjutant General of Wisconsin, and Project Officer CW-4 Donald D. Erickson, who directed the volunteer efforts of the Wisconsin National Guardsmen, are also gratefully acknowledged for their assistance to the Survey. ------- iv NATIONAL EUTROPHICATION SURVEY STUDY LAKES STATE OF WISCONSIN LAKE NAME COUNTY Altoona Eau Claire Beaver Dam Barron Beaver Dam Dodge Big Eau Pleine Marathon Browns Racine Butte des Morts Winnebago Butternut Price, Ashland Castle Rock Flowage Juneau Como Walworth Crystal Vilas Delavan Walworth Eau Claire Eau Claire Elk Price Geneva Walworth Grand Green Lake Green Green Lake Kegonsa Dane Koshkonong Jefferson, Rock, Dane Lac La Belle Waukesha Long Price Middle Walworth Nagawi cka Waukesha Oconomowoc Waukesha Okauchee Waukesha Petenwell Flowage Juneau Pewaukee Waukesha Pigeon Waupaca Pine Waukesha Poygan Winnebago, Waushara Rock Jefferson Rome Pond Jefferson, Waukesha Round Waupaca Shawano Shawano ------- V LAKE NAME COUNTY Sirinissippi Dodge Swan Columbia Tainter Dunn Tichigan Racine Townline Oneida Trout Vilas Wapogassett Polk Wausau Marathon Willow Oneida Winnebago Winnebago, Fond Du Lac, Cal umet Wisconsin Columbia Wissota Chippewa Yellow Burnett ------- Cedar TAINTER LAKE TRIBUTARY SAMPLINC SITE LAKE SAMPLING SITE ‘SEWAGE TREATMEN1 FACILITY - .

Rate-Limiting Nutrient: Because of a significant loss of nitrogen in the assay sample, the results are not reliable (see page 8). The lake data indicate phosphorus limitation in November but nitrogen limitation in June and August. C. Nutrient Controllability: 1. Point sources--During the sampling year, Tainter Lake received a total phosphorus load at a rate far in excess of that proposed by Vollenweider (in press) as “dangerous”; i.e., a eutrophic rate (see page 14). However, Survey data indicate that less than one percent of the phosphorus load was from point sources (neglecting an undefined load from the Colfax Cooperative Creamery and point sources beyond the Survey lim- its), and it is concluded that point-source phosphorus control would have little effect on the trophic condition of Tainter Lake. Note that if the entire Tainter Lake drainage had a phosphorus export equal to that of apparently unimpacted Lamb Creek, the lake still would have received a total phosphorus load at a rate nearly five times the eutrophic rate. ------- 2 2. Non-point sources--Areal or non-point sources appear to be contributing high amounts of phosphorus to Tainter Lake. For example, the total phosphorus export of Lamb Creek, which does not appear to be impacted by any point sources at all, was 104 lbs/mi 2 of drainage during the sampling year (see page 14). However, the phosphorus export of the Red Cedar River was over twice that of Lamb Creek; this probably is due to underestimation of the Colfax contribution as well as unmeasured point-source contributions further upstream in the rather exten- sive Red Cedar drainage basin. ------- II. INTRODUCTION Tainter Lake, Dunn County, is part of the lower Chippewa River drainage which is tributary to the Mississippi River. The topography of the basin is primarily rolling glacial terrain. Recreational uses of the lake include swimming, boating, and fishing. Game fish present are northern pike, walleyes, largemouth bass, and pan- fish. Much of the shoreline is developed, and 16 resorts provide boat rentals and services. Public access is provided. ------- 4 III. LAKE AND DRAINAGE BASIN CHARACTERISTICS A. Lake Morphometry*: 1.

LAKE WATER QUALITY SUMMARY Tainter Lake was sampled three times during the open-water season of 1972 by means of a pontoon-equipped Huey helicopter. Each time, samples for physical and chemical parameters were collected from three stations on the lake and from a number of depths at each station (see map, page vi). During each visit, a single depth-integrated (15 feet or near bottom to surface) sample was composited from the stations for phytoplankton identi- fication and enumeration; and during the last visit, a single five-gallon depth-integrated sample was composited for algal assays. Also each time, a depth-integrated sample was collected from each of the stations for chlorophyl a analysis. The maximum depths sampled were 7 feet at station 1, 15 feet at station 2, and 30 feet at station 3. The results obtained are presented in full in Appendix B, and the data for the fall sampling period, when the lake was essentially well- mixed, are summarized below. Note, however, the Secchi disc summary is based on all values. For differences in the various parameters at the other sampling times, refer to Appendix B. ------- 6 A.

Discussion - The control yield of the assaj alga, Selenastrum capri- cornutum , indicates that potential primary productivity of Tainter Lake was high at the time the sample was collected. Also, the results indicate the lake was nitrogen limited. However, there was a significant loss of inorganic nitrogen ------- 9 (247 igIl) in the sample from the time of collection until the assay was begun; and the results, therefore, are con- sidered unreliable. Had the loss not occurred, it is most likely the sample would have been phosphorus limited. The lake data support this conclusion. The mean nitrogen to phosphorus ratio for all November samples was 14 to 1 and was 12 to 1 at station 1, 14 to 1 at station 2, and 14 to 1 at station 3 (i.e., phosphorus limitation would be expected). The lake data also indicate Tainter Lake may be nitrogen limited at times. The N/P ratios at the other sampling times were 7/1 or less at all stations. 0. Trophic Condition: Survey data indicate Tainter Lake is eutrophic. Despite the very short hydraulic retention time of this lake, of the 46 Wis- consin lakes studied, 38 had less mean total and dissolved phos- phorus, 38 had less mean inorganic nitrogen, 24 had less mean chlorophyll a, and 19 had greater Secchi disc transparency. ------- 10 V. NUTRIENT LOADINGS (See Appendix C for data) For the determination of nutrient loadings, the Wisconsin National Guard collected monthly near-surface grab samples from each of the tribu- tary sites indicated on the map (page vii) except for the high runoff months of April and May, when two samples were collected at most stations, and during the colder months of the year when one or more samples were omitted at some stations because of low flow and/or ice cover. Sampling was begun in September, 1972, and was completed in September, 1973. Through an interagency agreement, stream flow estimates for the year of sampling and a “normalized” or average year were provided by the Wis- consin District Office of the U.S. Geological Survey for the tributary sites nearest the lake. In this report, nutrient loads for sampled tributaries were determined by using a modification of a U.S. Geological Survey computer program for calculating stream loadings*. Nutrient loads for unsampled “minor tributaries and immediate drainage” (“ZZ” of U.S.G.S.) were determined by using the pounds per square mile per year calculated for Lamb Creek at B-i and multiplying that by the ZZ area in square miles. The City of Colfax declined participation in the Survey, and nutrient loads attributed to that source were estimated (as municipal wastes only) at 2.5 lbs P and 7.5 lbs N/capita/year. * See Working Paper No. 1. ------- 11 Since no information on the contribution of the Colfax Cooperative Creamery to the Colfax wastewater treatment plant was available, the loads attributed to Colfax are not adjusted for the industrial loads. Loads attributed to the Red Cedar River are those measured at 44-2 minus the loads estimated for the Colfax SIP. A. Waste Sources: 1. Known municipal - Pop.

Yearly Loading Rates: In the following table, the existing phosphorus loading rates are compared to those proposed by Vollenweider (in press). Essentially, his “dangerous” rate is the rate at which the receiving waters would become eutrophic or remain eutrophic; his “permissible” rate is that which would result in the receiving water remaining oligotrophic or becoming oligotrophic if mor- phornetry permitted. A mesotrophic rate would be considered one between “dangerous” and “permissible”.
