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.
-------
Ill
Beyond the single lake analysis, broader based correlations
betv/een 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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data and a report by others ,(Ketelle and Uttormark,
1971) indicate that Lake Tohopekaliga is eutrophic. It ranked
28th in overall trophic quality when the 41 Florida water bodies
sampled in 1973 were compared using a combination of six lake
parameters*. Twenty-seven of the lakes had less median total
phosphorus, 28 had less median dissolved phosphorus, 24 had
less median inorganic nitrogen, 21 had less mean chlorophyll
a^, and 25 had greater mean Secchi disc transparency.
Survey limnologists noted that the lake water was humic-
colored and observed surface concentrations of algae in March.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Tohopekaliga
was nitrogen limited at the times the samples were collected
(03/13/73 and 11/07/73). The lake data indicate nitrogen
limitation at the other sampling time as well.
C. Nutrient Controllability:
1. Point sources—It is calculated that point sources
(including indirect sources) accounted for 52.0% of the total
phosphorus load and 51.0% of the total nitrogen load to the
lake during the sampling year.
See Appendix A.
-------
2
The City of Orlando McLeod Road plant and the Orange County
Southwest plant collectively contributed 27.9% of the total phos-
phorus and 33.2% of the total nitrogen inputs to Lake Toho-
pekaliga. Shingle Creek, which receives the effluent from these
plants, flows through extensive swampy areas where the channel
is poorly defined. Although this area may be a nutrient sink
part of the year (Federico and Brezonik, 1975), it is assumed that
excessive nutrient loads, such as those discharged to the creek,
eventually reach Lake Tohopekaliga (McCaffrey, 1976).
The phosphorus loading of 4.89 g/m2 measured during the samp-
ling year is 11 times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic loading. Even complete removal
of phosphorus at the point sources considered in this report would
still leave a loading of 2.34 g/m2/yr (more than five times the
eutrophic loading); and, although the critical level for Florida
lakes may be somewhat higher than that suggested by Vollenweider
(see page 14) it does not seem likely that the degree of phos-
phorus reduction attainable by municipal point-source control
would result in a shift to phosphorus limitation and a significant
improvement in the trophic condition of the lake.
The persistent nitrogen limitation during Survey sampling,
resulting from a combination of relatively low inorganic nitrogen
concentrations (median = 0.200 mg/1) and rather high orthophosphorus
levels (median = 0.152 mg/1), indicates nitrogen control might
-------
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 Tohopekaliga
is needed to assess the probable effects of point-source nitrogen
control.
2. Non-point sources—It is estimated that non-point sources
contributed about 48% of the total phosphorus load and 49% of the
total nitrogen load reaching Lake Tohopekaliga during the sampling
year. The gaged tributaries contributed an estimated 33.3% of
the phosphorus and 36.5% of the nitrogen inputs.
Reportedly, dairy wastes, pasture runoff, and urban drainage
contribute nutrients to the lake (Ketelle and Uttormark, 1971).

III. WATER QUALITY SUMMARY
Lake Tohopekaliga 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 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 (near bottom to surface) sample
was composited from the stations for phytoplankton identification and
enumeration; and during the first and third visits, 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 1.8 meters at
stations 1 and 4 and 1.5 meters at stations 2 and 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

3. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary prodictivity
of Lake Tohopekaliga was high at the times the samples were
collected. Also, in all assays, the lack of increase in
yields when only orthophosphorus was added and the marked
increase in yields when nitrogen alone was added indicate
the lake was nitrogen limited at those times.
The lake data also indicate nitrogen limitation; the
mean inorganic nitrogen/orthophosphorus ratios were less
than 2/1 at all sampling stations and 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). 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 South Port Canal (C-l), Partin
Canal (B-l), and St. Cloud Canal (at East Lake Tohopekaliga outlet
station 61 C-l) were determined by using a modification of a U.S. Geolo-
gical Survey computer program for calculating stream loadings*. The St.
Cloud Canal phosphorus load measured at station 41 D-l was about 29 times
greater than the load measured at the outlet of East Lake Tohopekaliga,
and it is believed sampling station 41 D-l was too close to the Saint
Cloud wastewater treatment plant discharge point to permit adequate
mixing of the effluent in the canal at the sampling point.
The nutrient loads attributed to upstream point sources exceeded
those measured in Shingle Creek at station A-l, and the background loads
for this stream and the unsampled "minor tributaries and immediate drain-
age" ("II" of U.S.G.S.) were estimated using the nutrient loads, in kg/km2/yr,
at station B-l and multiplying by the Shingle Creek and II areas in km2.
See Working Paper No. 175.
-------
11
The indirect point-source loads leaving upstream East Lake Tohopekaliga
were calculated by multiplying the nutrient loads leaving that lake (5,025
kg P and 228,820 kg N) by the fractions of the totals of the nutrient loads
contributed by the McCoy Air Force Base and the Orlando Jetport during the
sampling year (0.139 for P and 0.022 for N). The Saint Cloud Canal loads
were adjusted accordingly.
The operators of the Saint Cloud and Kissimmee Highlands wastewater
treatment plants provided monthly effluent samples and corresponding flow
data. The City of Orlando (McLeod Road Plant), Orange County Southwest,
and the City of Kissimmee did not participate; nutrient loads attributed
to these sources are those reported by McCaffrey (1976).

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".
Vollenweider's model may not be applicable to water bodies
with short hydraulic retention times.
