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 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'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.
-------
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.
ACKNOWLEDGMENT
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.

I. CONCLUSIONS
.A. Trophic Condition:
Survey data indicate Lake Keowee is mesotrophic. It ranked
first in overall trophic quality when the 13 South Carolina
lakes sampled in 1973 were compared using a combination of six
parameters*. None of the other lakes had less median total
phosphorus and median dissolved orthophosphorus, one had less
median inorganic nitrogen, two had less mean chlorophyll a^, and
none of the other lakes had greater mean Secchi disc transparency.
Marked depression of hypolimnetic dissolved oxygen occurred at
sampling stations 1, 2, and 3 in September and November and at
station 4 in June and November; depletion occurred at station 4
in September.
Survey limnologists did not observe any nuisance conditions
during sampling visits. However, it is reported that the upper
portion of the Cane Creek embayment is eutrophic and often sup-
ports nuisance populations of blue-green algae (Anonymous, 1973).
The same source indicates algal blooms occur throughout the lake,
but the Survey phytoplankton data do not indicate bloom conditions
during the sampling year (see page 6).
B. Rate-Limiting Nutrient:
The algal assay results indicate Lake Keowee was phosphorus
See Appendix A.

limited at the time the sample was collected (06/25/73). The
lake data indicate phosphorus limitation at all sampling sta-
tions and times.
C. Nutrient Controllability:
1. Point sources—The only known municipal point source
(Walhalla) contributed an estimated 6.8% of the total phos-
phorus input to Lake Keowee during the sampling year. While
even complete removal of phosphorus at the Walhalla wastewater
treatment facility would not appreciably lower the overall lake
loading of 0.31 g/m2 measured during the sampling year, it is
likely that a high degree of phosphorus control would result
in a significant improvement in the trophic condition of the
Cane Creek embayment.
2. Non-point sources—The non-point contributions of sampled
tributaries accounted for an estimated 81.1% of the total phos-
phorus load reaching the lake during the sampling year. This
may be an overestimate to some degree because of a number of
small unsampled domestic and industrial point sources in the
Lake Keowee drainage (see page 9). However, the phosphorus
export rates of the tributaries were comparatively low (see
page 11) and indicate point-source impacts probably were not
significant.

III. LAKE WATER QUALITY SUMMARY
Lake Keowee 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 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 36.6 meters at station 1, 48.8 meters at station 2, 32.3 meters
at station 3, and >21.0* meters at station 4.
The sampling results are presented in full in Appendix D and
are summarized in the following table.
* The maximum sampling depth at station 4 in November was indicated to
be 61 meters or nearly 13 meters more than the maximum depth of the lake;
the maximum depth sampled at that time is not known.

2. Discussion -
The control yield of the assay alga, Seljenastrum capri-
cornutum, indicates that the potential primary productivity
of Lake Keowee was low at the time the sample was collected
(06/25/73). Also, the significant increases in yields with
increasing amounts of orthophosphorus and the lack of increase
when only nitrogen was added indicate phosphorus limitation
at that time.
The lake data also indicate phosphorus limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 34/1
or greater at all sampling times, and phosphorus limitation
would be expected.
-------
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 v), 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
calculated using mean concentrations and mean flows. The nutrient
loads shown for Cane Creek are those measured minus the Wai hall a
point-source loads.
The Keowee River upstream from the lake was not accessible for
sampling, and nutrient loads in the river and the unsampled "minor
tributaries and immediate drainage" ("ZZ" of U.S.G.S.) were esti-
mated using the means of the nutrient loads, in kg/km2/year, at
stations C-l, E-l, F-l, and G-l and multiplying the means by the
Keowee River and ZZ areas in km2.
The operator of the Wai hall a wastewater treatment plant provided
monthly effluent samples but could not provide flow data. Therefore,
-------

nutrient loads were calculated using the means of the nutrient concen-
trations in the samples submitted (Appendix E) and the mean plant flow
reported by the South Carolina Department of Health and Environmental
Control (Anonymous, 1973):
A. Waste Sources*:
1. Known municipal -
Pop. Mean Flow Receiving
Name Served Treatment (m3/d) _ Water
Walhalla 2,530 aer. pond 1,022.0** Cane Creek
In addition, there are at least six privately-owned domestic-
waste facilities in the Lake Keowee drainage. The nutrient
impact of these small facilities is not known, but three of them
discharge to sampled tributaries and nutrient contributions are
included in the loads attributed to the streams.
2. Known industrial - There are at least seven industrial waste
treatment facilities of unknown significance in the drainage. Three
of these discharge to sampled tributaries and nutrient contributions,
if any, are included in the stream loads.

E. 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.
Total Phosphorus Total Nitrogen
Total AccumulatedI Total Accumulated
grams/m2/yr 0.31 0.07 5.9 loss*
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Lake Keokee:
"Dangerous" (eutrophic loading) 0.72
"Permissible" (oligotrophic loading) 0.36
* There was an apparent loss of nitrogen during the sampling year. This may
have been due to nitrogen fixation in the lake, solubilization of pre-
viously sedimented nitrogen, recharge with nitrogen-rich ground water,
-or unsampled point sources discharging directly to the lake or to unsam-
pled tributaries. Whatever the cause, a similar nitrogen loss has occurred
at Shagawa Lake, Minnesota, which has been intensively studied by EPA's
former National Eutrophication and Lake Restoration Branch (Malueg et al.,
1975).
