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.
-------
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
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 Secession is eutrophic. It ranked
eleventh in overall trophic quality when the 13 South Carolina
lakes sampled in 1973 were compared using a combination of six
parameters*. Nine of the lakes had less median total phosphorus,
three had less and two had the same median dissolved phosphorus,
eight had less median inorganic nitrogen, all of the other lakes
had less mean chlorophyll a^ and six had greater mean Secchi disc
transparency.
Except for turbidity, Survey limnologists did not note any
nuisance conditions during the sampling year; but oxygen depres-
sion or depletion occurred at station 1 at all sampling times,
and depression occurred at station 2 in June and September.
B. Rate-Limiting Nutrient:
The algal assay results indicate phosphorus limitation at the
time the assay sample was taken (06/26/73). The lake data indi-
cate phosphorus limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources—The phosphorus loads from point sources
amounted to 74.7% of the total reaching the lake during the samp-
ling year. The Anderson wastewater treatment plant contributed
* See Appendix A.
-------
2
68.0% of the total, and the Belton plant contributed 6.7%.
1 l ,-i
During the sampling year, Lake Secession received a total
phosphorus loading about five times that proposed by Vollen-
weider (Vollenweider and Dillon, 1974) as a eutrophic loading
(see page 12). However, the hydraulic retention time of the
lake is not known, and it is possible that Vollenweider's model
does not apply. Nonetheless, the existing trophic condition of
the lake is evidence of excessive nutrient loads.
While even complete removal of phosphorus at the Anderson
and Belton wastewater treatment plants would still leave a phos-
phorus loading of 1.81 g/m2/yrt in view of the questionable
applicability of Vollenweider's model and the phosphorus-limited
condition of the lake, it is likely that a high degree of phos-
phorus control at the two point sources would result in a sig-
nificant improvement in the trophic condition of the lake.
2. Non-point sources—Except for Hencoop Creek, the phos-
phorus export rates of the Lake Secession tributaries were quite
low (page 11) and compare well with the export rates of South
Carolina tributaries elsewhere; e.g., the mean of the rates of
Lake Keowee* tributaries was 17 kg/km*/yr (range of 15 to 19 kg/
km2/yr).
The cause of the higher rate of Hencoop Creek is not known
but may have been the result of urban drainage from Belton (see
map, page v).

III. LAKE WATER QUALITY SUMMARY
Lake Secession 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 three 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 phyto-
plankton 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 19.2 meters at station 1, 11.6 meters at station
2, and 4.0 meters at station 3.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum. indicates that the potential primary productivity
of Lake Secession was relatively low at the time the sample
was collected (06/26/73). The increase in yield with the
addition of phosphorus and the lack of increase in yield
when only nitrogen was added indicate phosphorus limitation.
The lake data also indicate phosphorus limitation (i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were
greater than 16/1 at all sampling times, and phosphorus limi-
tation 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
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" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads at stations C-l, D-l, and E-l, in kg/km2/year, and
multiplying the means by the II area in km2.
The operators of the Anderson and Bel ton wastewater treatment plants
provided monthly effluent samples and corresponding flow data.

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.
