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 fresh water 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.
-------
Ill
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
fresh water 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

SARDIS LAKE
STORE! NO. 2805
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Sardis Lake is eutrophic, although
it ranked first in overall trophic quality when the five Missis-
sippi lakes sampled in 1973 were compared using a combination of
six parameters*. None of the other lakes had less median total
phosphorus, one had less and one had the same median dissolved
phosphorus, one had less median inorganic nitrogen, one had less
mean chlorophyll £, and none had greater mean Secchi disc trans-
parency. Depression of dissolved oxygen with depth occurred at
all four sampling stations in June and August.
B. Rate-Limiting Nutrient:
There was a significant change in nutrient levels during
shipment of the assay sample and the results are not repre-
sentative of conditions in the lake at the time the sample was
taken (06/13/73).
The lake data indicate phosphorus limitation at all sampling
times.
C. Nutrient Controllability:
1. Point sources—The only known point source impacting
Sardis Lake during the sampling year was the town of Oxford
* See Appendix A.

which contributed 3.2% of the total phosphorus load. Even with
complete removal of phosphorus at Oxford, the loading would
still be nearly 1% times that proposed by Vollenweider (Vollen-
weider and Dillon, 1974) as a eutrophic loading (see page 13).
However, since Sardis Lake is phosphorus limited, any reduction in
phosphorus loading would be expected to improve the trophic con-
dition of the lake.
2. Non-point sources—During the sampling year, the Little
Tallahatchie River contributed 86.1% of the total phosphorus load;
Clear Creek, 2.5%; Toby Tubby Creek, 1.2%; Hurricane Creek, 0.9%;
and the remaining four streams collectively contributed 1.4% of
the load. The ungaged drainage areas were estimated to have con-
tributed 3.1% of the load.
The mean of the phosphorus export rates of the Sardis Lake
tributaries was only 18 kg/km2/year (see page 12). This is the
lowest mean export rate of the five lake drainages sampled in
Mississippi. For example, the mean phosphorus export rate of
the tributaries of nearby Arkabutla Reservoir* was 52 kg/km2/year
(range of 32 to 77 kg/km2/year).

III. LAKE WATER QUALITY SUMMARY
Sardis 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 four
stations on the lake and from a number of depths at each station
(see map, page v). During each visit, a single depth-integrated
(4.6 m 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 16.8 meters at station 1, 14.6 meters at station 2, 14.0
meters at station 3, and 13.4 meters at station 4.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

C. Limiting Nutrient Study:
There was a significant change in nutrients during ship-
ment of the sample, and the assay results are not represent-
ative of conditions in the lake at the time the sample was
collected.
The lake data indicate phosphorus limitation; i.e., the
mean inorganic nitrogen/orthophosphorus ratios were 14/1 or
greater at all sampling stations and times, with the single
exception of station 4 (nearest the nutrient point source)
where the mean N/P ratio was 8/1 in November.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Mississippi National
Guard collected intermittent monthly near-surface grab samples from
each of the tributary sites indicated on the map (page v). Sampling
was begun in August, 1973, was completed in May, 1974, and was inter-
rupted twice during the year due to severe flooding.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Mississippi 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*. Note that Wilborn Creek (B-l}
was not sampled because of inaccessibility; the drainage area and flow
of this stream are included in the "II" area and flow. 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, in kg/kmVyear, at stations A-2, C-l, D-l, E-l, F-l, H-l,
and J-l and multiplying the means by the II area in km2.
The operator of the Oxford wastewater treatment plant provided
monthly effluent samples but only limited flow data; therefore, nutri-

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 Accumulated Total Accumulated
grams/mVyr 1.12 0.19 14.2 loss*
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Sardis Lake:
"Dangerous" (eutrophic loading) 0.74
"Permissible" (oligotrophic loading) 0.37
* There was an apparent loss of nitrogen during the sampling year. This
may have been due to nitrogen fixation in the lake, solubilization of
previously sedimented nitrogen, recharge with nitrogen-rich ground water,
unknown and unsampled point sources discharging directly to the lake, or
insufficient outlet sampling. 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).
