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 that Lake William C. Bowen is meso-
eutrophic. It ranked seventh in overall trophic quality when
the 13 South Carolina lakes sampled in 1973 were compared using
a combination of six parameters*. Three of the lakes had less
median total phosphorus, six had less and one had the same median
dissolved phosphorus, nine had less median inorganic nitrogen,
three had less mean chlorophyll a_, and five had greater mean
Secchi disc transparency.
No nuisance conditions were noted by Survey 1imnologists;
however, some emergent vegetation was observed in the shallow
areas near sampling station one, and oxygen depression or depletion
occurred at station three.
B. Rate-Limiting Nutrient:
The algal assay results show phosphorus limitation at the time
the sample was collected (03/29/73). The lake data indicate phos-
phorus limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources--The phosphorus contribution of the Landrum
wastewater treatment plant accounted for 9.7% of the total load
reaching the lake.
* See Appendix A.
-------
2
During the sampling year, the lake received a total phos-
phorus loading only slightly more than that proposed by Vollen-
weider (Vollenweider and Dillon, 1974} as an oligotrophic loading
(see page 11). However, the hydraulic retention time of the
lake is not known, and it is possible that Vollenweider's model
is not applicable. Also, the apparent loss of phosphorus from
the lake during the year while over 20% of the nitrogen was
retained (pages 9 and 10), indicates an underestimation of phos-
phorus inputs or phosphorus sources discharging directly to the
lake or to unsampled tributaries.
While a phosphorus wash-out could have occurred if inputs
had been recently reduced, there is no indication that such a
reduction occurred, and a need for further study of the phos-
phorus balance of the lake is indicated.
2. Non-point sources--Although the sampled tributaries
accounted for over 76% of the total load, the phosphorus export
rates were quite low during the sampling year (page 10).

III. LAKE WATER QUALITY SUMMARY
Lake William C. Bowen was sampled three times during the open-
water season of 1972 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 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 2.1 meters at station 1, 7.0 meters at station 2,
and 10.7 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 the lake was low at the time the sample was collected (03/
29/73). The increase in yield with increased levels of phos-
phorus, as well as the lack of increase when only nitrogen
was added, indicates phosphorus limitation.
The lake data also indicate phosphorus limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 26/1
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
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 B-l and C-l, in kg/km2/year, and multi-
plying the means by the II area in km2.
The operator of the Landrum wastewater treatment plant 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.
