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.

SALUDA LAKE
STORET NO. 4515
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Saluda Lake is mesotrophic. How-
ever, since the mean hydraulic retention time of this water body
is a very short six days, it more closely resembles a slow-moving
stream, and the term "moderately-enriched" may be a better de-
scription of this lake.
Saluda Lake ranked fourth in overall trophic quality when
the 13 South Carolina lakes sampled in 1973 were compared using
a combination of six parameters*. Seven of the lakes had less
median total phosphorus, three had less and two had the same
median dissolved phosphorus, three had less median inorganic
nitrogen, 11 had greater mean Secchi disc transparency, but none
of the other lakes had less mean chlorophyll a^ (1.5 ug/1). However,
the low chlorophyll a^ concentrations and lack of transparency
(the mean Secchi disc depth was less than 0.6 meters) indicate
primary productivity was light-limited rather than nutrient limi-
ted. Survey limnologists commented on the highly turbid water at
each of the sampling stations and times.
Survey limnologists observed floating and emergent macrophytes
in the shallows near both sampling stations.
* See Appendix A.

B. Rate-Limiting Nutrient:
The algal assay results indicate that Saluda Lake was phos-
phorus limited at the time the assay sample was collected (06/23/
73). The lake data indicate phosphorus limitation at the other
sampling times as well. However, primary productivity in the lake
probably is light-limited rather than nutrient-limited.
C. Nutrient Controllability:
1. Point sources—No known point sources contributed phos-
phorus to Saluda Lake during the sampling year.
The present phosphorus loading of 15.23 g/m2/yr is five times
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading (page 11). However, the mean hydraulic
retention time of Saluda Lake is a very short six days, and it
is unlikely that Vollenweider's model is applicable.
2. Non-point sources—The phosphorus contributions of non-
point sources accounted for the entire load impacting Saluda
Lake during the year. The Saluda River contributed 99.6%, and
the ungaged tributaries accounted for an estimated 0.3%.
The phosphorus export rate of the Saluda River (46 kg/km2/yr)
was rather high compared to the rates of the tributaries of down-
stream Lake Greenwood* (mean of 21 kg/km2/yr; range of 9 to 36
kg/km2/yr). The higher export rate may have been due to unmeasured
sources impacting one or more of the three branches of the Saluda
River above the lake; e.g., septic tanks in Slater (see map, page v),

III. LAKE WATER QUALITY SUMMARY
Saluda 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 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 9.1 meters at station 1 and 4.3 meters at station 2.
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 Saluda Lake was moderate at the time the sample was col-
lected. Also, increasing yields with increasing concentra-
tions of orthophosphorus indicate that the lake was limited
by phosphorus at that time. Note that the addition of only
nitrogen resulted in a yield not significantly different
from that of the control.
The lake data also indicate phosphorus limitation. At
both stations and all sampling times, the mean inorganic
nitrogen/orthophosphorus ratios were 23/1 or greater, and
phosphorus limitation would be expected. However, primary
productivity in the lake probably is light-limited rather
than nutrient-limited.
-------
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 for unsampled
"minor tributaries and immediate drainage" ("II" of U.S.G.S.) were estimated
using the means of the nutrient loads, in kg/km 2/year, at stations B-l
and C-l of Lake William C. Bowen** and multiplying the means by the II
area in km2.
No known point sources impacted Saluda Lake during the sampling year.

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.
