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
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)
expresses sincere appreciation to the Florida Department of Environ-
mental Regulation for professional involvement, and to the Florida
National Guard for conducting the tributary sampling phase of the
Survey.
Joseph W. Landers, Jr., Secretary of the Department of Environ-
mental Regulation; John A Redmond, former Director of the Division
of Planning, Technical Assistance, and Grants; and Dr. Tim S. Stuart,
Chief of the Bureau of Water Quality, provided invaluable lake docu-
mentation and counsel during the survey, reviewed the preliminary
reports, and provided critiques most useful in the preparation of this
Working Paper series.
Major General Henry W. McMillan (Retired), then the Adjutant
General of Florida, and Project Officer Colonel Hugo F. Windham,
who directed the volunteer efforts of the Florida National Guard,
are also gratefully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Haines is eutrophic. It
ranked 15th in overall trophic quality when the 41 Florida
lakes sampled in 1973 were compared using a combination of
six parameters*. Eleven of the lakes had less and one had
the same median total phosphorus and median dissolved phos-
phorus, eight had less and one had the same median inorganic
nitrogen, 17 had less mean chlorophyll
-------
2
the critical loading for Florida lakes may be somewhat higher
than that suggested by Vollenweider (see page 11), the trophic
condition of the lake is indicative of excessive nutrient loads.
It is calculated that diversion of the Lake Alfred treatment plant
effluent would reduce the phosphorus loading to 0.16 g/m2/yr (a
mesotrophic loading).
2. Non-point sources—It is estimated that non-point sources,
including precipitation, contributed approximately 23% of the total
phosphorus and 94% of the total nitrogen inputs to Lake Haines.
The 1970 Winter Haven U.S.G.S. quadrangle map indicates that
land use around the lake is mainly agricultural (citrus) and
marsh.

III. WATER QUALITY SUMMARY
Lake Haines 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 collected for chlorophyll ^analysis. During the first visit, a
single 18.9-liter depth-integrated sample was taken for algal assays.
The maximum depth sampled was 3.7 meters.
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 Haines was moderately high at the time the sample
was collected (03/08/73). The results also indicate nitrogen
limitation. Note that the addition of orthophosphorus alone
did not result in an increase in yield, but the addition of
nitrogen alone resulted in a yield double that of the control.
The lake data substantiate nitrogen limitation at the
time the sample was collected; i.e., the mean inorganic nitrogen/
orthophosphorus ratio was 10/1. Mean N/P ratios in September
and November were 12/1 and 6/1, respectively.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of outlet nutrient loadings, the Florida National
Guard collected monthly near-surface grab samples from the outlet site
indicated on the map (page v). Sampling was begun in March, 1973, and
was completed in February, 1974.
Through an interagency agreement, flow estimates for the year of samp-
pi ing and a "normalized" or average year were provided by the Florida
District Office of the U.S. Geological Survey for the outlet canal.
In this report, nutrient loads for the outlet canal were determined
by using a modification of a U.S. Geological Survey computer program
for calculating stream loadings*. Nutrient loads for unsampled "minor
tributaries and immediate drainage" ("II" of U.S.G.S.) were estimated
using the mean nutrient loads from citrus groves, in kg/km2/year (Brezonik
and Shannon, 1971), and multiplying by the II area in km2.
The operator of the Lake Alfred wastewater treatment plant provided
monthly effluent samples and corresponding flow data.

D. 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.

grams/m2/yr 0.68 0.63 15.6 14.2
Vollenweider phosphorus loadings

hydraulic retention time of Lake Haines:

"Permissible" (oligotrophic loading) 0.10
