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)K 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.
-------
m
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 Webster Lake is eutrophic. It
ranked ninth in overall trophic quality when the 27 Indiana
lakes sampled in 1973 were compared using a combination of
six parameters*. Eight of the lakes had less and one had the
same median total phosphorus, four had less and three had the
same median dissolved phosphorus, ten had less median inorganic
nitrogen, 12 had less mean chlorophyll a_, and ten had greater
mean Secchi disc transparency. Marked depression of dissolved
oxygen with depth occurred at station 2 in August and depletion
occurred in October.
Survey limnologists observed submerged and emergent macro-
phytes in the shallows near both sampling stations.
B. Rate-Limiting Nutrient:
The algal assay results indicate phosphorus limitation at
the time the sample was collected (05/02/73). The lake data
indicate phosphorus limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources—The phosphorus contribution of the Epworth
Forest Church Camp wastewater treatment plant amounted to an esti-

mated 9.7% of the total reaching Webster Lake during the sampling
year. Lakeshore septic tanks were estimated to have contributed
1.6%, but a shoreline survey would be necessary to determine the
significance of those sources.
The present phosphorus loading of 1.04 g/m2/yr exceeds that
proposed by Vollenweider (Vollenweider and Dillon, 1974) as a
eutrophic loading (see page 11).
Sewage treatment facilities are planned for the Town of North
Webster which also will treat wastes from the community on the
northeast corner of the lake, including wastes from the Epworth
Forest Church Camp (BonHomme, 1976). It is calculated that the
elimination of the Camp discharge to the lake will reduce the
loading to 0.94 g/m2/yr. While this will still exceed the eutro-
phic loading, the lake is phosphorus limited, and the reduced phos-
phorus loading should at least reduce the incidence and severity
of nuisance conditions in the lake.
2. Non-point sources--Non-point phosphorus inputs were esti-
mated to have accounted for over 88% of the total load. The
Tippecanoe River accounted for 80.4%, and the ungaged drainage
areas were estimated to have contributed 6.7%.
The non-point nutrient export of the Tippecanoe River was
17 kg P/km2/yr. This rate compares well with other unimpacted
streams studied in this part of Indiana.

III. LAKE WATER QUALITY SUMMARY
Webster 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 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. The maximum depths sampled were 1.5 meters
at station 1 and 14.0 meters at station 2.
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 Webster Lake was low at the time the assay sample was
collected. The significant increase in yield when only
orthophosphorus was added indicates phosphorus limitation.
Note that the addition of nitrogen alone did not result in
an increase in yield compared to the control yield. Based
on these results, phosphorus limitation is indicated.
The lake data also indicate phosphorus limitation; the
mean inorganic nitrogen/orthophosphorus ratios were 58/1 or
greater at all sampling times, and phosphorus limitation would
be expected.

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 months of February and March 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 for unsampled
"minor tributaries and immediate drainage" ("II" of U.S.G.S.) were esti-
mated using the nutrient loads at station A-2, in kg/km2/year, and multi-
plying by the II area in km2.
The operator of the Epworth Forest wastewater treatment plant pro-
vided monthly effluent samples but no flow data; nutrient loads were
estimated at 0.567 kg P and 3.401 kg N/capita/year, and flows were
estimated at 0.3785 m3/capita/day. Note that the estimate of phos-
phorus loading was reduced by 50% to adjust for the Indiana phosphate
detergent ban in effect 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
