Appendices 13 ------- 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 {§303(e)>, water quality criteria/standards review {§303(c)>, clean lakes {§314(a,b)>, and water quality monitoring {§106 and §305(b)} activities mandated by the Federal Water Pollution Control Act Amendments of 1972. ------- m 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 Indiana State Board of Health for professional involvement, to the Indiana National Guard for conducting the tributary sampling phase of the Survey, and to those Indiana wastewater treatment plant operators who provided effluent samples and flow data. The staff of the Division of Water Pollution Control, Indiana State Board of Health, provided invaluable lake documentation and counsel during the Survey, reviewed the preliminary reports, and provided critiques most useful in the preparation of this Working Paper series. Major General Alfred F. Ahner, Adjutant General of Indiana, and Project Officers Lt. Colonel Charles B. Roberts (Retired) and Colonel Robert L. Sharp, who directed the volunteer efforts of the Indiana National Guardsmen, are also gratefully acknowledged for their assistance to the Survey. ------- IV NATIONAL EUTROPHICATION SURVEY STUDY LAKES STATE OF INDIANA LAKE NAME Bass Cataract Crooked Dallas Geist Hamilton Hovey James James Long Marsh Mississinewa Maxinkuckee Monroe Morse 01 in Oliver Pigeon Sylvan Tippecanoe Versailles Wawassee Webster Westler Whitewater Winona Witmer COUNTY Starke Owen, Putnam Steuben LaGrange Hamilton, Marion Steuben Posey Kosciusko Steuben Steuben Steuben Grant, Miami, Wabash Marshall Brown, Monroe Hami1 ton LaGrange LaGrange Steuben Noble Kosciusko Ripley Kosciusko Kosciusko LaGrange Union Kosciusko LaGrange ------- DALLAS & WESTLER LAKES Tributary Sampling Site X Lake Sampling Site Sewage Treatment Facility o 1/2 1 11/2, Cm. Map Location 4133— 85 26 ------- DALLAS LAKE STORE! NO. 1845 I. CONCLUSIONS A. Trophic Condition: Survey data indicate that Dallas Lake is eutrophic. Of the 27 lakes sampled in Indiana in 1973, Dallas Lake ranked tenth in overall trophic quality using a combination of six parameters*. Ten of the lakes had less median total phosphorus, 18 had less median dissolved phosphorus, 11 had less median inorganic nitrogen, eight had less mean chlorophyll a^ and eight had greater mean Secchi disc transparency. Near-depletion or depletion of dissolved oxygen occurred in the hypolimnion at both stations in August and October. Survey limnologists noted light algal blooms and emergent and submerged macrophytes. B. Rate-Limiting Nutrient: The algal assay results show that Dallas Lake was phosphorus limited at the time the assay sample was collected (05/04/73). The lake data indicate phosphorus limitation in August as well but nitro- gen limitation in October. C. Nutrient Controllability: 1. Point sources—During the sampling year, Dallas Lake received a total phosphorus loading just over 1% times that proposed by Vollen- weider (Vollenweider and Dillon, 1974) as a eutrophic loading. The * See Appendix A. ------- 2 only known direct point source, Whetzel High School, is estimated to have contributed 16.4% of the total phosphorus load. An indirect point source, the Village of Wolcottville, impacts upstream Witmer Lake; and, considering the relatively small phos- phorus retention in the intervening water bodies (less than 33% in Witmer Lake and less than 12%-in Westler Lake), this source prob- ably impacts Dallas Lake as well. While even complete removal of phosphorus at the Whetzel High School treatment plant would still leave a loading of about 1.3 g/m2/yr (0.3 g/m2/yr in excess of the eutrophic loading), if a high degree of phosphorus removal is provided at the High School plant and at the Wolcottville plant, it is likely to result in persistent phosphorus limitation in Dallas Lake (see page 7) and a reduction in the incidence and severity of nuisance algal blooms. 2. Non-point sources—During the sampling year, the non-point phosphorus contributions of the\ Westler Lake outlet and the immediate drainage accounted for nearly 82% of the total phosphorus load to Dallas Lake. ------- II.

LAKE WATER QUALITY SUMMARY Dallas Lake 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 a number of depths at two stations on the lake (see map, page v). During each visit, a single depth-integrated (4.6 m to surface) » sample was composited from the stations for phytoplankton identification and enumeration; and during the first visit, a single 18.9-liter depth-integrated sample was composited for algal assays. Also each time, a depth-integrated sample was collected from each of the stations for chlorophyll a^ analysis. The maximum depths sampled were 28.6 meters at station 1 and 21.3 meters at station 2. The sampling results are presented in full in Appendix D and are summarized in the following table. ------- A.

Discussion - The control yield of the assay alga, Selenastrum capri- cornutum, indicates that the potential primary productivity of Dallas Lake was moderately high at the time the assay sample was collected (05/04/73). The results also indicate phosphorus limitation at that time. Note the four-fold increase in yield with the addition of orthophosphorus alone and the lack of a significant increase in yield with the addition of only nitrogen. The lake data indicate phosphorus limitation in August as well (the mean inorganic nitrogen/orthophosphorus ratio was 16/1); however, the mean N/P ratio in October was 9/1, and nitrogen limitation would be expected. ------- 8 IV. NUTRIENT LOADINGS (See Appendix E for data) For the determination of nutrient loadings, the Indiana 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 months of February and March when two samples were collected. Sampling was begun in June, 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 provided by the Indiana 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 estimated using the nutrient loads, in kg/km2/year, at station C-l of nearby Witmer Lake** and multiplying by the ZZ area in km2. The operator of the Whetzel High School wastewater treatment plant did not participate in the Survey, and nutrient loads were estimated at 0.567 kg P and 3.401 kg N/capita/year (note that the per-capita estimate for phosphorus was reduced by 50% to adjust for the Indiana phosphate-detergent ban instituted in January, 1972). * See Working Paper No. 175. ** See Working Paper No. 349. ------- A.

Yearly Loads: In the following table, the existing phosphorus loadings are compared to those proposed by Vollenweider (Vollenweider and Dillon, 1974). Essentially, his "dangerous" loading is one at which the receiving water would become eutrophic or remain eutrophic; his "permissible" loading is that which » would result in the receiving water remaining oligotrophic or becoming oligotrophic if morphometry permitted. A meso- trophic loading would be considered one between "dangerous" and "permissible". Note that Vollenweider's model may not be applicable to water bodies with short hydraulic retention times.
