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.
. j'
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 Hater Pollution Control Act Amendments of 1972.
-------
iii
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 betv/een 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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Jessup is hypereutrophic.
It ranked thirty-fifth in overall trophic quality when the 41
Florida lakes sampled in 1973 were compared using a combination
of six parameters*. Twenty-nine lakes had less median total
phosphorus, 30 had less median dissolved phosphorus, 32 had
less and one had the same median inorganic nitrogen, 30 had
less mean chlorophyll £, and 38 had greater mean Secchi disc
transparency.
Survey limnologists noted heavy concentrations of emergent
vegetation and algae during the sampling. A mean chlorophyll a^
concentration of 77 ug/1 and high numbers of blue-green algae
(see page 6) further indicate the over-enriched condition of
the lake.
B. Rate-Limiting Nutrient:
The algal assay results indicate Lake Jessup was limited by
nitrogen at the time the assay sample was collected (03/14/73).
The lake data indicate nitrogen limitation at the other sampling
times as well.
C. Nutrient Controllability:
1. Point sources—It is calculated that during the sampling
year, 29.9% of the total phosphorus and 19.0% of the total
* See Appendix A.
-------
2
nitrogen inputs to Lake Jessup were contributed by the seven
wastewater treatment plants which discharge indirectly to the
lake.
The sampling year phosphorus loading of 4.24 g/m2 is almost
9 times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading. However, even complete removal
of phosphorus at the point sources considered in this report would
still leave a loading of 2.97 g/m2/yr (six times the eutrophic
loading); and although Florida lakes may assimilate phosphorus at
higher levels than those suggested by Vollenweider (see page 14),
it does not seem likely that the degree of phosphorus reduction
attainable by municipal point-source control would result in a
significant improvement in the condition of Lake Jessup.
The marked nitrogen limitation during Survey sampling -
resulting from moderate concentrations of inorganic nitrogen
(median = 0.290 mg/1) and high levels of orthophosphorus (median
= 0.288 mg/1) - suggests consideration of nitrogen control to
reduce the rate of eutrophication of the lake. However, emphasis
during the Survey was on the controllability of phosphorus, and
a more intensive study of the nitrogen budget of Lake Jessup is
needed to determine the feasibility and probable effect of nitrogen
control.
2. Non-point sources—It is estimated that about 70% of the
-------
3
total phosphorus and 81% of the total nitrogen inputs to Lake
Jessup were from non-point sources. The principal contributor
was Howell Creek which accounted for 32% of the phosphorus and
nearly 24% of the nitrogen. While the mean nutrient exports of
five of the tributaries were relatively high (232 kg P and 837 kg
N/km2/yr), the exports of Sweetwater Creek were exceptionally high
(1,201 kg P and 8,212 kg N/km2/yr; see page 13).
The 1970 photorevised U.S.G.S. Casselberry quadrangle map
indicates extensive urban areas in the Lake Jessup drainage and
citrus production as a major agricultural land use.

III. WATER QUALITY SUMMARY
Lake Jessup was sampled three times in 1973 by means of a
pontoon-equipped Huey helicopter. Each time, near-surface samples
for physical and chemical parameters were collected from two sta-
tions on the lake (see map, page v). During each visit, a single
sample was composited from the stations for phytoplankton identi-
fication and enumeration; and during the first visit, a single
18.9-liter sample was composited for algal assays. Also each time,
a sample was collected from each of the stations for chlorophyll a_
analysis.
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 Lake Jessup was very high at the time the sample was
collected (03/14/73). Also, the lack of significant change
in yields with increased levels of orthophosphorus until
nitrogen was also added indicates the lake was nitrogen
limited at that time.
Nitrogen limitation is also indicated by the lake data;
i.e., the mean inorganic nitrogen to orthophosphorus ratios
were less than 2 to 1 at all sampling times.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Florida National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the month
of June when two samples were collected from four of the seven tribu-
taries. Sampling was begun in March, 1973, and was completed in
February, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normilized" 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 sampled tributaries were deter-
mined 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/yr, at station E-l and multiplying by the ZZ area in km2.
The operators of the Winter Springs, Casselberry, and Country
Club Heights wastewater treatment plants provided monthly effluent
samples and corresponding flow data (the Winter Springs plant was
replaced by a new activated sludge plant after Survey sampling was
completed).
* See Working Paper No. 175.
-------
10
The operators of the North Orlando Townsites, Winter Park, Maitland,
and Howell Park wastewater treatment plants did not participate in the
Survey; nutrient loads from these sources were estimated at 1.134 kg P
and 3.401 kg N/capita/year, and flows were estimated at 0.3785 m3/capita/
day.
The latter three plants impact upstream Lake Howell, and it is assumed
the Lake Howell retained 29% of the phosphorus and 50% of the nitrogen
contributed by these plants; i.e., the measured retentions during the
sampling year. The loads attributed to those plants were adjusted
accordingly.

E. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Note, however, 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 result
in the receiving water remaining oligotrophic or becoming oligo-
trophic if morphometry permitted. A mesotrophic 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.

* 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
underestimation of the minor tributary and immediate drainage load.
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).
