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
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)

I. INTRODUCTION
Lake Jessie is one of the Winter Haven chain of lakes. The hydrol-
ogy of this chain is complex, and the U.S. Geological Survey questions
whether realistic analyses of nutrient loadings to the lakes can be
made; i.e., depending on the operation of control gates, wind direction
and velocity, and other factors, flows in the connecting canals may have
reversed from one sampling time to the next (Anderson, 1974).
II. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Jessie is eutrophic. It
ranked ninth in overall trophic quality when the 41 Florida
lakes sampled in 1973 were compared using a combination of
six parameters*. Eleven lakes had less median total phosphorus,
six had less and one had the same median dissolved phosphorus,
five had less median inorganic nitrogen, 16 had less mean
chlorophyll au and five had greater mean Secchi disc transparency.
Survey limnologists noted that emergent aquatic vegetation
was present in the shallows along about half of the shoreline
in November.
* See Appendix A.
-------
B. Rate-Limiting Nutrient:
The algal assay results are not considered indicative of
conditions in the lake at the time of sampling. The lake data
indicate nitrogen limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources—During the sampling year, the only known
point source, the Flamingo Shores MHP wastewater treatment
plant contributed an estimated 1.6% of the total phosphorus input
to Lake Jessie.
The estimated sampling year phosphorus loading of 3.25 g/m2
is more than eight times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic loading. Assuming non-point
loading estimates are reasonable, it appears that complete phosphorus
removal at the point source would still leave a loading well in
excess of the eutrophic loading; and even though Florida lakes
may assimilate phosphorus at higher levels than those suggested
by Vollenweider (see page 12 )> it does not seem likely that
point-source phosphorus reduction would result in a significant
improvement in the trophic condition of the lake.
2. Non-point sources — It is estimated that 61% of the
phosphorus input to Lake Jessie was contributed by the Lake
Sanitary drainage basin. It 1s iikeiy that control of phosphorus
resulting from agricultural activities around Lake Sanitary would
be necessary to significantly reduce this input to Lake Jessie.
-------
Minor tributaries and immediate drainage contributed an
estimated 36% of the total phosphorus loading to Lake Jessie.
Some urban development is presently occurring on the south
and west shores, and an airport is located near the east
shore. Citrus groves are also located within the drainage basin.

IV. WATER QUALITY SUMMARY
Lake Jessie was sampled three times during 1973 by means of a
pontoon-equipped Huey helicopter. Each time, samples for physical
and chemical parameters were collected from two or more depths at
one station on the lake (see map, page v). During each visit, a
single depth-integrated (near bottom to surface) sample was collected
for phytoplankton identification and enumeration, and a similar
sample was taken for chlorophyll a. analysis. During the first visit,
a single 18.9-liter depth-integrated sample was collected for algal
assays. The maximum depth sampled was 2.7 meters.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

C. Limiting Nutrient Study:
The algal assay results are not considered indicative of
conditions in Lake Jessie at the time of sampling (03/08/74)
because of substantial changes in nutrient concentrations in
the sample between the time of collection and the beginning
of the assay.
The lake data indicate nitrogen limitation; i.e., mean
inorganic nitrogen/orthophosphorus ratios were 11/1 or less
at all sampling times.
-------
V. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Florida National
Guard collected monthly near-surafce grab samples from each of the
tributary sites indicated on the map (page v). Sampling was begun
o
in March, 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 Florida District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for Unnamed Canal A--1 were
determined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads in the un-
sampled outlet canal were calculated with the estimated mean outflow
and the mean nutrient concentrations in the lake.
Nutrient loads for unsamples "minor tributaries and immediate
drainage" ("II" of U.S.G.S.) were estimated using the nutrient loads,
in kg/km2/year, at station A-l and multiplying by the II area in km2.
The operator of the Flamingo Shores wastewater treatment plant pro-
vided 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). However, note that Florida lakes may be
able to assimilate phosphorus at a somewhat higher level than
that suggested by Vollenweider (Shannon and Brezonik, 1972).
Essentially, Vollenweider's "dangerous" loading is one at
which the receiving water would become eutrophic or remain
eutrophic; his "permissible" loading is that which would re-
sult in the receiving water remaining oligotrophic or becoming
oligotrophic if morphometry permitted. A mesotrophic loading
would be considered one between "dangerous" and "permissible".
Vollenweider's model may not be applicable to water bodies
with short hydraulic retention times.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/m2/yr 3.25 3.04 9.4 5.6
Vollenweider phosphorus loadings
(g/m2/yr) based on estimated mean depth and
hydraulic retention time of Lake Jessie:

"Permissible" (oligotrophic loading) 0.20
