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(c.)>, 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.
-------
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 Indiana State Board of
Health for professional involvement, to the Indiana National
Guard for conducting the tributary sampling phase of the Survey,
and to those Indiana wastewater treatment plant operators who
provided effluent samples and flow data.
The staff of the Division of Water Pollution Control, Indiana
State Board of Health, provided invaluable lake documentation and
counsel during the Survey, reviewed the preliminary reports, and
provided critiques most useful in the preparation of this Working
Paper series.
Major General Alfred F. Ahner, Adjutant General of Indiana,
and Project Officers Lt. Colonel Charles B. Roberts (Retired)
and Colonel Robert L. Sharp, who directed the volunteer efforts
of the Indiana National Guardsmen, are also gratefully acknowledged
for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Sylvan Lake is eutrophic. It ranked
eighteenth in overall trophic quality when the 27 Indiana lakes
sampled in 1973 were compared using a combination of six param-
eters*. Twenty-five lakes had less median total phosphorus, 20
had less median dissolved phosphorus, one had less median inorganic
nitrogen, 24 had less mean chlorophyll a_, and 19 had greater mean
Secchi disc transparency. Near-depletion of dissolved oxygen with
depth occurred at station 2 in October.
Survey limnologists reported a heavy algal bloom in progress
in August.
The trophic condition of Sylvan Lake appears to have improved
somewhat since 1963-64 when it was studied by Wetzel (1966) and
categorized as hypereutrophic and "...one of the most productive
lakes in the temperate region of the world". It is likely that
at least some of the improvement can be attributed to the Indiana
phosphate detergent ban which became effective in January, 1972.
B. Rate-Limiting Nutrient:
Because of nutrient changes in the sample, the algal assay
results are not considered indicative of conditions in the lake at

the time the sample was taken (05/10/73). The lake data indi-
cate that Sylvan Lake was nitrogen limited at all sampling times.
C. Nutrient Controllability:
1. Point sources--The point-source phosphorus contribution
amounted to 44.3% of the total reaching Sylvan Lake during the
sampling year. The City of Kendallville contributed 41.1%, and
lakeshore septic tanks were estimated to have contributed 3.1%
of the total.
The present phosphorus loading of 1.26 g/m2/yr is just over
two times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 12). Complete removal of
phosphorus at the Kendallville treatment plant would lower the
overall loading to 0.74 g/m2/yr. While this would still exceed
the eutrophic loading of 0.62 g/m2/yr, it is likely the reduced
loading would result in persistent phosphorus limitation and
improvement in the trophic condition of the lake.
2. Non-point sources—Over 55% of the total phosphorus input
to Sylvan Lake was contributed by non-point sources during the
sampling year. The Henderson Lake Ditch contributed 37.5%; Oviatt
Ditch, 10.7%; and the Latta Lake outlet contributed 1.9% of the
total. Ungaged tributaries were estimated to have contributed 4.3%
of the total phosphorus input.
The phosphorus export rates of the Sylvan Lake tributaries com-

III. LAKE WATER QUALITY SUMMARY
Sylvan Lake was sampled three times during the open-water season
of 1973 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from a
number of depths at two stations on the lake (see map, page v). During
each visit, a single depth-integrated (4.6 m or near bottom to surface)
sample was composited from the stations for phytoplankton identification
and enumeration; and during the second 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. The maximum depths sampled were 3.0
meters at station 1 and 5.5 meters at station 2.
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 the lake at the time of sampling because of sig-
nificant changes in nutrient concentrations in the sample
between the field and the laboratory. The lake data indicate
nitrogen limitation; the mean inorganic m'trogen/orthophosphorus
ratios were 12/1 or less at all sampling stations and times.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Indiana National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the high
runoff month of February when two samples were collected. Sampling
was begun in June, 1973, and was completed in May, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Indiana District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
determined 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 means of the
nutrient loads at stations B-l and D-l, in kg/km2/year, and multi- •
plying the means by the ZZ area in km2.
The operator of the Kendallville wastewater treatment plant pro-
vided monthly effluent samples and corresponding flow data.
Estimated phosphorus loads were reduced by 50% to adjust for the
phosphate detergent limitation in effect in Indiana since January, 1972.

E. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Essentially, his "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 meso-
trophic 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/m2/yr 1.26 loss* 44.6 18.2
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Sylvan Lake:
"Dangerous" (eutrophic loading) 0.62
"Permissible" (oligotrophic loading) 0.31
* There was an apparent loss of phosphorus during the sampling year. This
may have been due to solubilization of previously sedimented phosphorus,
recharge with phosphorus-rich ground water, or unknown and unsampled
point sources discharging directly to the lake or to one of the ungaged
tributaries.
