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
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)

ROSS BARNETT RESERVOIR
STORE! NO. 2804
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Ross Barnett Reservoir is eutrophic.
Of the five Mississippi water bodies sampled in 1973, Ross Barnett
Reservoir ranked second in overall trophic quality when compared
using a combination of six parameters*. One of the water bodies
had less median total phosphorus, none of the others had less
median dissolved phosphorus and median inorganic nitrogen, one
had greater mean Secchi disc transparency, but none of the others
had greater mean chlorophyll a_. Depression of dissolved oxygen
with depth occurred at sampling stations 1 and 2 in June and
August.
During their visits to the reservoir, Survey limnologists
did not observe any nuisance conditions other than turbidity.
B. Rate-Limiting Nutrient:
Due to a loss of nutrients in the sample before the algal
assay could be conducted, the results are not representative of
conditions in the reservoir at the time the sample was taken
(06/14/73). However, the reservoir data indicate phosphorus limi-
tation at stations 2, 3, and 4 and nitrogen limitation at station
1 in June; phosphorus limitation at all stations in August; and
* See Appendix A.

nitrogen limitation at all stations, except station 3, in
November.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Ross Barnett
Reservoir received a total phosphorus loading more than 3%
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 12).
It is estimated that the known point sources contributed
less than 2% of the phosphorus load. Even complete removal of
phosphorus at these sources would only lower the loading from
the existing 3.56 g/m2/year to 3.50 g/m2/year, or 3^ times the
eutrophic loading, and it is not likely that point-source phos-
phorus control would result in any significant improvement in
the trophic condition of the reservoir.
2. Non-point sources—It is calculated that non-point sources
contributed more than 98% of the total phosphorus load to the
reservoir during the sampling year.
The phosphorus export rates of Pelahatchie Creek and
Fannegusha Creek were markedly greater than that of the Pearl
River (see page 11). While the higher export rate of Pelahatchie
Creek may have resulted from underestimation of the phosphorus
loads from the Pelahatchie lagoons, the even higher rate of
Fannegusha Creek apparently is due to agricultural practices in
that drainage.

III. LAKE WATER QUALITY SUMMARY
Ross Barnett Reservoir 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 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 7.9 meters at station 1, 11.6 meters at station 2, 4.6 meters
at station 3, and 4.6 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:
A 58% loss of inorganic nitrogen and a 54% loss of total
phosphorus occurred in the assay sample between the time of
collection and the beginning of the assay. Consequently, the
assay results are not representative of conditions in the
reservoir at the time the sample was taken (06/14/73).
The reservoir data indicate a spatial and temporal com-
bination of limiting nutrients, although it will be noted
that station 1, nearest the point sources, tended toward
nitrogen limitation while the stations further away tended
toward phosphorus limitation.
Following is a tabulation of the mean inorganic nitrogen/
orthophosphorus ratios for each of the stations and sampling
times with the indicated limiting nutrient in parentheses.

Nitrogen limitation, as indicated by the in-lake nitrogen to
phosphorus ratios, does not necessarily mean that the trophic
condition of the lake can be improved by controlling nitrogen
inputs. In most cases, the apparent condition of nitrogen-
limitation results from excessive phosphorus inputs from point
sources and is often accompanied by a corresponding increase in
primary production. In such cases, the reversal of the enriched
condition depends upon phosphorus control, not nitrogen control.

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 August, 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. The data from sampling sites A-2
(Pearl River) and B-l (Pelahatchie Creek) were not used in this report.
Station A-2 was found to be essentially a lake site, and station B-l
is not an outlet of the reservoir. Therefore, the drainage areas and
flows of each were subtracted from the appropriate totals.
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 nutrient loads,
in kg/km2/year, at station C-l and multiplying by the ZZ area in km2.
The operators of the Pelahatchie wastewater treatment plants pro-
vided monthly effluent samples and estimated flow data. The Town of
Carthage did not participate in the Survey, and nutrient loads were

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.
