Appendices 16 ------- 11 FOREWORD The National Eutrophication Survey was initiated in 1972 in response to an Administration commitment to investigate the nationwide threat of accelerated eutrophication to freshwater 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 nonpoint 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 watershed 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 ------- 111 planning [ 303(e)], water quality criteria/standards review [ 303(c)], clean lakes [ 3l4(a,b)], and water quality monitoring [ l06 and §305(b)] activities mandated by the Federal Water Pollution Control Act Amendments of 1972. 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 freshwater 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. ACKNOWLEDGMENTS The staff of the National Eutrophication Survey (Office of Research and Development, U.S. Environmental Protection Agency) expresses sincere appreciation to the Maryland Department of Natural Resources and the Maryland Department of Health and Mental Hygiene for professional involve- ment and to the Maryland National Guard for conducting the tributary sampling phase of the Survey.

CONCLUSIONS A. Trophic Condition: Based upon field observations and survey data, Liberty Reservoir is considered early mesotrophic. Survey limnolo- gists reported that the water was clear, appearing light green in color, with no visible aquatic plants and an algal bloom occurring only in the spring. Chlorophyll a levels ranged from a low of 3.0 micrograms per liter in the spring to a high of 14.4 micrograms per liter in the fall with a mean of 6.3 micrograms per liter. The lake was characterized by high concentrations of total phosphorus. B. Rate-Limiting Nutrient: Algal assay results indicate that Liberty Reservoir was limited by available phosphorus levels. Spikes with phosphorus, or nitrogen and phosphorus simultaneously result in increases in assay yield. Additions of nitrogen alone did not stimulate a growth response. The ratio of available nitrogen to phos- phorus in sampled waters substantiates phosphorus limitation. ------- 2 C. Nutrient Controllabiliy: 1. Point sources - The nutrient loading rate of 0.37 g/m 2 /yr to Liberty Reservoir is one-third of the “perniissible” level proposed by Vollenweider (in press). Point sources contribute 4.0% of the total phosphorus loading. Total elimination of known point sources could result in maintaining the present high quality of the water. 2. Nonpoint sources - The total phosphorus load from nonpoint sources accounted for 96.0% of the loading reaching Liberty Reservoir; major tributaries contributed 73.0%, while minor tributaries and immediate drainage contributed 18.4%. According to the State of Maryland Sanitary Survey, 1970, agricultural pollution was most prevalent. Also observed contributing to the loading of the reservoir were surface oil storage, surface scavenger dumping, incorrectly located storm drains, and numerous types of dumps. ------- 3 II. LAKE AND DRAINAGE BASIN CHARACTERISTICS Lake and drainage basin characteristics are itemized below. Lake surface area and volume were obtained from “Reservoirs in the United States.” Mean depth was determined by dividing the volume by the lake surface area. Tributary data were provided by the Maryland District Office of the US. Geological Survey (USGS) (outlet drainage area includes the lake surface area). The outlet data for normalized flow and daily and monthly flows for time of sampling were dividied into spillage and diversion segments. The spillage and diversions were combined into total outflow. Mean hydraulic retention time was obtained by dividing the lake volume by the mean flow of the outlet. Precipitation values are estimated by methods as outlined in National Eutrophication Survey (NES) Working Paper No. 175. A table of metric/English conversions is included as Appendix D. A.

LAKE WATER QUALITY SUMMARY Liberty Reservoir was sampled three times during the open-water season of 1973 by means of a pontoon-equipped Huey helicopter. Each time, samples for physical and chemical parameters were collected from four stations on the lake and from a number of depths at each station (see map, page V). During each visit, depth-integrated samples were collected from each station for chlorophyll a analysis and phytoplankton identification and enumeration. During the first visit, 18.9-liter depth-integrated samples were coniposited for algal assays. Maximum depths sampled were 41.1 meters at station 1, 7.6 meters at station 2, 16.2 meters at station 3, and 7.6 meters at station 4. For a more detailed explanation of National Eutrophi- cation Survey methods, see NES Working Paper No. 175. The results obtained are presented in full in Appendix B and are summarized in III A for waters at the surface and at the maxi- mum depth for each site. Resuits of the phytoplankton counts and chlorophyll a determinations are included in III B. Results of the limiting nutrient study are presented in III C. ------- A.

Discussion — The results of the algal assay with Selenastrum capri- cornutum indicate that the potential for primary production in Liberty Reservoir was high at the time of sampling. In- creased growth of the test alga in response to an addition of orthophosphorus indicates that the lake was phosphorus limited when sampled. Spikes with nitrogen and phosphorus simultaneously resulted in maximum yield. The addition of nitrogen alone did not stimulate growth beyond the control yield. The total available nitrogen to dissolved phosphorus ratio of 244:1 further indicates phosphorus limitation. ------- 10 IV. NUTRIENT LOADINGS (See Appendix C for data) For the determination of nutrient loadings, the Maryland National Guard collected monthly near-surface grab samples from each of the tributary sites indicated on the map (page v), except for the high runoff month of February when two samples were col- lected. Sampling was begun in May 1973, and was completed in May 1974. Through an interagency agreement, stream flow estimates for the year of sampling and a “normalized” or average year were pro- vided by the Maryland District Office of the USGS for the tributary sites nearest the lake. In this report, nutrient loads for sampled tributaries were determined by using a modification of the USGS computer program for calculating stream loadings. Nutrient loads indicated for tributaries are those measured minus known point source loads, if any. Nutrient loading for unsampled “minor tributaries and immediate drainage” (“ZZ” of USGS) were estimated by using the mean of the nutrient loads, in kg/km 2 /year, at stations B(l) and C(l) and multiplying the means by the ZZ area in km 2 . The operator of the Finksburg A.T. & T., Montrose Girls School, and Black and Decker-#2 wastewater treatment plants pro- vided monthly effluent samples and corresponding flow data. ------- 11 A.

Yearly Loading Rates: In the following table, the existing phosphorus loading rates are compared to those proposed by Vollenwelder (in press). Essentially, his “dangerous” rate is the rate at which the receivingwaters 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- phometry permitted. A mesotrophic rate would be considered one between “dangerous” and “permissible”.
