Appendices 19 ------- 11 FOREWORD The National Eutrophication Survey was initiated in 1972 in response to an Administration corrinitment to investigate the nation- wide 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 non-point source pollution abatement in lake watersheds. ANALYTIC APPROACH The mathematical and statistical procedures selected for the Survey 1 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 ANALYSI 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 [ 3O3(c’ ], clean lakes [ 3l4(a ,b)] , and water quality monitoring [ lO6 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 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. AC KNO WL EDGMENT The staff of the National Eutrophication Survey (Office of Research & Development, U. S. Environmental Protection Agency) expresses sincere appreciation to the South Carolina Department of Health and Environmental Control for professional involvement, to the South Carolina National Guard for conducting the tributary sampling phase of the Survey, and to those South Carolina waste- water treatment plant operators who voluntarily provided effluent samples and flow data. The staff of the South Carolina Bureau of Wastewater and Stream Quality Control 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 Robert L. McCrady, the Adjutant General of South Carolina, and Project Officer Lt. Colonel John P. DuPre (Retired), who directed the volunteer efforts of the South Carolina National Guardsmen, are also gratefully acknowledged for their assistance to the Survey. ------- iv NATIONAL EUTROPHICATION SURVEY STUDY LAKES STATE OF SOUTH CAROLINA NAME COUNTY Clark Hill Abbeville, McCor- mick, SC; Colum- bia, Elbert, Lin- coln, McDuffie, Wilks, GA Fishing Creek Chester, Lancaster Greenwood Greenwood, Laurens, Newberry Hartwell Anderson, Oconee, Pickeris, SC; Franklin, Hart, Stephens, GA Keowee Oconee, Pickens Marion Berkeley, Calhoun, Claredon, Orange- burg, Sumter Moultrie Berkeley Murray Lexington, Newberry, Richiand, Saluda Robinson Chesterfield, Dar- 1 ington Saluda Greenville, Pickens Secession Abbeville, Anderson Wateree Fairfield, Kershaw, Lancaster William C.

CONCLUSIONS A. Trophic Condition: Survey data indicate Lake Wylie is eutrophic. It ranked eighth in overall t’rophic quality whèn the 13 South Carolina lakes sampled in 1973 were compared using a combination of six parameters*. Six of the lakes had less median total phos- phorus, nine had less and one had the same median dissolved phosphorus, seven had less median inorganic nitrogen, four had less mean chlorophyll a, and eight had greater mean Secchi disc transparency. Marked depres ion ofdissolved oxygen with depth occurred at stations 1, 2, and 3’in July. Survey limnologists did not observe any nuisance conditions during sampling visits. B. Rate—Limiting Nutrien1 : The algal assay r ’esults are not representative of conditions in the lake because of a significant change in nutrients in the sample from the time of collectionth the beginning of the assay. However, the lake data indicate ph’osphorus limitation at all sam- pling times. C. Nutrient Controllability: 1. Point sources--The phosphorus contributions Ot listed * See Appendix A. ------- 2 point sources amounted to 39.5% of the total load reaching Lake Wylie during the sampling year. The two Gastonia, NC, plants collectively contributed 18.6%; Belmont, NC, 8.4%; Kings Mountain, NC, 5.1%; and the remaining ten plants collectively contributed 7.3% of the total load. The total phosphorus loading of 8.38 g/m 2 measured during the sampling year is over five times that proposed by Vollen- weider (Vollenweider and Dillon, 1974) as a eutrophic loading (see page 17). Even complete removal of phosphorus at the listed point sources would still leave a loading of about 5 g/n1 2 /yr. How- ever, there are additional point sources beyond the 40-kilometer limit of the Survey* that contribute significantly to the phos- phorus load as indicated by the high export rates of some of the tributaries (see page 16). Six additional North Carolina municipal wastewater treatment plants discharge in the upper portion of the South Fork Catawba River and contribute to the high export rate of that stream. These include Conover (S.W. plant), Hickory (S.E. plant), Lin- colnton, Longview, Maiden, and Newton with a combined population equivalence of 25,250 (Anonymous, 1971). Also, six unsanipled point sources with a combined design flow of 2,270 m 3 /day dis- charge to Paw Creek (Taylor, 1976) and contribute to the very high phosphorus export rate of that stream. * See Working Paper No. 175, ‘. . .Survey Methods, 1973-1976”. ------- 3 Many municipal point sources also discharge to the Catawba River upstream from Lake Wylie. However, these sources probably contribute minimal amounts of phosphorus indirectly to Lake Wylie because of nutrient entrapment in the intervening reservoirs. For example, five communities contributed about 9% of the total phos— phorus load to Lake Norman* during the sampling year. However, almost 68% of that phosphorus was retained in Lake Norman, and 24% of the phosphorus leaving that lake was retained in Mountain Island Lake** (see map, page vi). Such entrapment is believed to account for the low phosphorus export rate of the Catawba River at station B-l (12 kg/km 2 /yr). As noted before, even if complete removal of phosphorus could be accomplished at the listed point sources, the remaining loading would still be about three times the eutrophic loading. However, considering all of the point sources impacting Lake Wylie and the persistent phosphorus limitation of primary productivity in the lake, it is likely that a high degree of phosphorus control at all point sources would result in an improvement in the trophic condition of Lake Wylie, particularly if a significant portion of the “non- point” phosphorus load discussed below proves to be controllable. The reduction of point—source phosphorus loads probably would benefit downstream Fishing Creek Reservoir*** as well. * Working Paper No. 387. ** Working Paper No. 386. *** Working Paper No. 430. ------- 4 2. Non-point sources--It is calculated that non-point sources contributed about 60% of the total phosphorus load to Lake Wylie during the sampling year. However, the high phosphorus export rates of the South Fork Catawba River (106 kg/km 2 ), Catawba Creek (142 kg/km 2 ), and Paw Creek (301 kg/km 2 ) indicate that phosphorus loads from unaccounted-for point sources and/or urban drainage significantly impacted those streams during the sampling year. Assuming that the mean of the phosphorus export rates of the Catawba River, Beaverdam Creek, Allison Creek, and Little Allison Creek is a typical non-point export rate for the Lake Wylie drain- age (i.e., 18 kg P/kni 2 /yr; see page 16), it is calculated that point and/or urban sources contributed an additional 144,275 kg P to the South Fork Catawba River and 8,670 kg P to Catawba Creek, and the six unsampled point sources contributed 9,960 kg P to Paw Creek. The addition of these apparent point-source loads to those listed herein would increase the point-source proportion of the total load from about 40% to 76%. ------- Name Catawba Ri ver S. Fk.

LAKE WATER QUALITY SUMMARY Lake Wylie 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 four stations on the lake (see map, page v). During each visit, a single depth-integrated (4.6 m or near bottom 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 18.0 meters at station 1, 11.6 meters at station 2, 11.3 meters at station 3, and 5.8 meters at station 4. The sampling results are presented in full in Appendix D and are summarized in the following table. ------- A.

The lake data indicate phosphorus limitation at all sam- pling times; i.e., mean inorganic nitrogen/orthophosphorus ratios were 15/1 or greater, and phosphorus limitation would be expected. ------- 10 IV. NUTRIENT LOADINGS (See Appendix E for data) For the determination of nutrient loadings, the South Carolina National Guard collected monthly near-surface grab samples from each of the tributary sites indicated on the map (page vi), except for the high runoff month of January when two samples were collected. Sampling was begun in February, 1973, and was completed in February, 1974. Through an interagency agreement, stream flow estimates for the year of sampling and a “normalized” or average year were provided by the South Carolina 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 shown are those measured minus point-source loads, if any. Nutrient loads for unsampled “minor tributaries and immediate drainage” (“ZZ” of U.S.G.S.) were estimated using the nutrient loads at station H-i, in kg/km 2 /year, and multiplying by the ZZ area in km 2 . The operators of the Belmont, Cramerton, Gastonia #1, Kings Mt., McAdenville, Mt. Holly Industrial, Ranlo, and Stanley, North Carolina, and two of the three Clover, South Carolina, wastewater treatment plants provided monthly effluent samples and corresponding flow data. However, the loadings of the two Clover plants are based on relatively few sam- ples. * See Working Paper No. 175. ------- 11 The operators of the Bessemer City, Dallas, and Gastonia #2, North Carolina, and Clover #3, South Carolina, wastewater treatment plants did not participate in the Survey; nutrient loads from these sources were estimated at 1.134 kg P and 3.401 kg N/capita/year, and flows were esti- mated at 0.3785 m 3 /capita/day. In addition to the listed point sources, a number of wastewater treatment plants located well beyond the 40-kilometer limit of the Survey* discharge to the South Fork Catawba River or its tributaries. These plants have a combined population equivalence of 25,250 (Anonymous, 1971) and include Conover (S.W. plant), Hickory (S.E. plant), Lincolnton, Long- view, Maiden, and Newton (see map, page vi). Also, six unsampled point sources with a combined design flow of 2,270 m 3 /day discharge to Paw Creek (Taylor, 1976). The many municipal point sources located well upstream in the Catawba River drainage probably contribute minimal amounts of nutrients indirectly to Lake Wylie because of nutrient entrapment in the intervening reservoirs.

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 ‘ 1 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.
