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)]f
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water 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 arid 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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data and reports by others (Ketelle and Uttormark, 1971;
Shannon and Brezonik, 1972) indicate Lake Apopka is hypereutrophic.
It ranked twenty-second in overall trophic quality when the 41 Florida
lakes sampled in 1973 were compared using a combination of six
lake parameters*. Nineteen of the lakes had less and one had
the same median total phosphorus, 12 had less median dissolved
phosphorus, 25 had less median inorganic nitrogen, 25 had less
mean chlorophyll a_, and 36 had greater mean Secchi disc trans-
parency.
Survey limnologists noted numerous patches of water hyacinth
and emergent vegetation along the shorelines near all sampling
stations. The numbers of blue-green algae in the phytoplankton
samples (page 7) further indicate the over-enriched condition of
this water body.
B. Rate-Limiting Nutrient:
There was a significant loss of nitrogen in the sample between
the time of collection and the beginning of the algal assay,
and the results are not representative of the conditions in the
lake at the time of sampling.
The lake data indicate phosphorus limitation at all stations in
March, nitrogen limitation at most stations in August, and nitrogen
limitation at all stations in November.
* See Appendix A.

C. Nutrient Controllability:
1. Point Sources—During the sampling year, point sources
contributed 77.4% of the total phosphorus load and 37.6% of the
total nitrogen load to Lake Apopka.
The major portion of the phosphorus load (58.2%) is estimated
to have been contributed by muck farms. Previous studies have
shown that prevalent agricultural practices contribute significant
nutrient loads to the lake (Sheffield, 1969; Huffstutler et al.,
1965; Klos, 1973). Other sources of phosphorus include the
wastewater treatment plant at Winter Garden, 12.2% of the total;
the Winter Garden citrus processing plant, 6.8%; and septic tanks
serving lakeshore dwellings, an estimated 0.1%.
The present phosphorus loading of 0.63 g/m2/year is almost
four times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading.
The State of Florida has directed the muck farm operators to
initiate on-site retention of stormwater runoff by building
holding ponds. At the time of preparation of this report, over
half the muck farms had such ponds and no longer discharged to
the lake. When stormwater retention is completed, the phosphorus
loading should be reduced to 0.26 g/m2/year (assuming no seepage
to the lake). An additional 85% phosphorus removal at the wastewater
treatment and citrus processing plants at Winter Garden would further
reduce the loading to 0.16 g/m2/year. These phosphorus reductions
-------

should result in an improvement in the trophic condition of Lake
Apopka since the critical phosphorus level for this lake may be
somewhat higher than that suggested by Vollenweider (see page 13).
The reductions probably would benefit downstream lakes Beauclair
and Dora* as well.
2. Non-point sources—Non-point sources accounted for 22.7%
of the phosphorus and 62.5% of the nitrogen inputs to the lake during
the sampling year. Unnamed Stream B-l contributed 13.9% of the phos-
phorus load and 34.3% of the nitrogen load.
Unnamed streams B-l and C-l had phosphorus exports of 300 and
569 kg/km2/year, respectively (see page 13). These rates are much
greater than the rate of a tributary of nearby Lake Minneola** (4
kg/km2/yr) and may be indicative of seepage from the muck farms and
citrus groves in the area. For this reason, point-source phosphorus
contributions may be greater than those indicated.

III. LAKE WATER QUALITY SUMMARY
Lake Apopka was sampled three times during 1973 by means of a pon-
toon-equipped Huey helicopter. Each time, samples for physical and
chemical parameters were collected from six stations on the lake and from
one or more depths at each station (see map, page v). During each visit,
a single depth-integrated (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.
Only near-surface samples were taken at stations 1, 2, 3, 5, and 6; and
the maximum depth sampled at station 4 was 1.8 meters.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

IV. NUTRIENT LOADINGS
(See Appendix C 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). 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 "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 the outlet and Unnamed Stream C-l
were determined by using a modification of a U.S. Geological Survey com-
puter program for calculating stream loadings*; nutrient loads for Unnamed
Stream B-l were estimated using the mean concentrations and the mean flow.
Nutrient loads shown are those measured minus point-source loads, if any.
Nutrient loads for agricultural areas (muck farms and citrus
groves) were based on estimates presented in the First Annual Report of
the Oklawaha Comprehensive River Basin Study (125.7 kg P/day and 340.1
kg N/day; Anonymous, 1971). Nutrient loads for that portion of the
"minor tributaries and immediate drainage" ("ZZ" Of U.S.G.S.) not included
in the agricultural areas were estimated using the means of the nutrient
exports of the tributaries of nearby lakes Griffin**, and Minneola** (12
kg P and 314 kg N/km2/year) and multiplying the means by the ZZ area in km2.
* See Working Paper No. 175.
** Respectively, Working Paper No. 254 and 266.
-------

The nutrient loads measured in Apopka-Beauclair Canal at station
A-l may have been somewhat higher than the loads at the outlet of Apopka
Lake due to discharges from muck farms along the canal upstream from
the sampling site (Sheffield, 1969; see map page y). For this reason,
accumulation of nutrients in the lake could have been greater than shown
on the following pages.
The operator of the Winter Garden wastewater treatment plant provided

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
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.
