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.
-------
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
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

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Grenada Lake is eutrophic. It
ranked third in overall trophic quality when the five Mississippi
lakes sampled in 1973 were compared using a combination of six
parameters*. Two of the lakes had less median total phosphorus,
three had less median dissolved phosphorus, three had less median
inorganic nitrogen, none had less mean chlorophyll £, and three
had greater mean Secchi disc transparency. Depression or near-
depletion of dissolved oxygen with depth occurred at all three
sampling stations in June and August.
Survey limnologists noted a pea-soup green appearance in
June, 1973.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Grenada Lake was phos-
phorus limited at the time the sample was collected (06/14/73).
The lake data indicate phosphorus limitation at all sampling times,
C. Nutrient Controllability:
1. Point Sources—The phosphorus contributions of known
point sources amounted to only about 3% of the total reaching
Grenada Lake during the sampling year. The three Coffeeville
* See Appendix A.
-------
2
sewage treatment facilities collectively contributed 1.0% of the
total. Other contributors were the communities of Calhoun City
(1.3%) and Bruce (0.9%).
The present phosphorus loading of 1.57 g/m2/yr is over
twice that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 12). Because of this, and
because Grenada Lake is phosphorus-limited, all phosphorus inputs
should be minimized to the greatest practicable extent to slow
the aging of this water body.
2. Non-point sources—Almost 97% of the total phosphorus
input to Grenada Lake came from non-point sources during the
sampling year. The Yalobusha River contributed 43.5% of the
total load; the Skuna River, 35.5%; Turkey Creek, 10.7%; and four
smaller tributaries collectively contributed 4.4% of the load.
The ungaged tributaries were estimated to have contributed 1.6%
of the total phosphorus load.
The mean of the phosphorus export rates of the Grenada Lake
tributaries was a relatively low 38 kg/km2/year (see page 12).
The somewhat higher rates of the Skuna River (49 kg/km2/year)
and Turkey Creek (50 kg/km2/year) may have resulted from under-
estimation of point-source phosphorus contributions to those
streams.

III. LAKE WATER QUALITY SUMMARY
Grenada 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
three 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 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 15.2 meters at station 1, 10.1 meters at station
2, and 16.2 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 Grenada Lake was low at the time the sample was collected.
Also, the addition of phosphorus alone produced a significant
increase in yield, but the addition of nitrogen alone did not.
These results indicate phosphorus limitation.
The lake data also indicate phosphorus limitation; i.e.,
at all sampling times, the mean inorganic nitrogen/orthophos-
phorus ratios were 14/1 or greater, and phosphorus limitation
would be expected.

IV. NUTRIENT LOADINGS
{See Appendix E for data)
For the determination of nutrient loadings, the Mississippi National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v). Sampling was begun in
August, 1973, and was completed in July, 1974.
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*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the nutrient
loads, in kg/kmVyear, at stations B-l, F-l, and G-l and multiplying the means
by the ZZ area in km2.
The operator of the Coffeeville #1 wastewater treatment plant
provided monthly effluent samples but no flow data, and the communities
of Bruce and Calhoun City did not participate in the Survey. Nutrient
loads for Coffeeville #1, Bruce, and Calhoun City were estimated at 1.134
kg P and 3.401 kg N/capita/year. The untreated wastes of Coffeeville #2
and #3 were estimated at 1.587 kg P and 4.263 kg N/capita/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.
