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)>,
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.

WESTLER LAKE
STORE! NO. 1841
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Westler Lake is eutrophic. Of the
27 Indiana water bodies sampled in 1973, Westler Lake ranked
thirteenth in overall trophic quality using a combination of
six parameters*. Twelve lakes had less and two had the same
median total phosphorus, 16 had less and one had the same median
dissolved phosphorus, 12 had less median inorganic nitrogen, nine
had less mean chlorophyll a_, and nine had greater mean Secchi
disc transparency.
Survey limnologists observed algal blooms and macrophytes
in the shallow areas at stations 1 and 2 in August. Hypolim-
netic dissolved oxygen was depleted at stations 1 and 2 in
August and October and at station 3 in October.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Westler Lake was phos-
phorus limited at the time the sample was collected (05/03/73).
The lake data indicate phosphorus limitation in August as well
but nitrogen limitation in October.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Westler Lake
received a total phosphorus loading over 2% times that proposed

by Vollenweider (Vollenweider and Dillon, 1974) as a eutrophic
loading.
Other than the estimated septic tanks loads, there were no
known point sources directly impacting the lake, However, the
Village of Wolcottville is an indirect source which impacts
Witmer Lake (see map, page v) and contributed 190 kg total phos-
phorus to that lake during the sampling year.
On the basis of the measured phosphorus retention in Witmer
Lake (less than 33% during the sampling year), it is calculated
that 90% phosphorus removal at Wolcottville would reduce the
total load to Westler Lake by more than 7% and would reduce the
loading rate to about 4 g/m2/yr. While this rate is still more
than two times Vollenweider's eutrophic rate, it is questionable
whether his model is applicable to Westler Lake because of the
short mean hydraulic retention time of the lake (27 days); and
it is possible that a high degree of phosphorus control at the
indirect point source would result in persistent phosphorus limi-
tation (see page 7) and a reduction in the incidence and severity
of nuisance algal blooms in Westler Lake. Also, the phosphorus
reduction probably would benefit downstream Dallas Lake (see
map, page v), since Westler Lake retained less than 12% of the
phosphorus load received during the sampling year.
2. Non-point sources—During the sampling year, the non-point
phosphorus contributions of the Witmer Lake outlet and the imme-
diate drainage accounted for 98% of the total phosphorus load to
Westler Lake.

III. LAKE WATER QUALITY SUMMARY
Westler 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 three stations on the lake (see map, page v).
During each visit, a single depth-integrated (4.6 m 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 8.5
meters at station 1, 8.8 meters at station 2, and 8.8 meters at sta-
tion 3.
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 Westler Lake was moderate at the time the assay sample
was collected. The results also indicate phosphorus limita-
tion at that time. Note that when only nitrogen was added,
the yield was not significantly increased over the control
yield; but, with the addition of orthophosphorus alone, the
yield increased 18-fold.
The lake data also indicate phosphorus limitation in
August (the mean inorganic nitrogen/orthophosphorus ratio
was 14/1) but nitrogen limitation in October (the mean N/P
ratio was 11/1).

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*.
The inlet station of Westler Lake is the outlet station of Witmer
Lake** (1842A-1), and the outlet station of Westler Lake is the inlet
station of Dallas Lake*** (1845B-1).
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the nutrient loads,
in kg/km2/year, at station C-l of nearby Witmer Lake and multiplying
by the ZZ area in km2.
Note that the estimated septic tank phosphorus loading was reduced
by 50% to adjust for the Indiana phosphate detergent ban instituted in
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 4.39 0.50 158.7 loss*
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Westler Lake:
"Dangerous" (eutrophic loading) 1.68
"Permissible" (oligotrophic loading) 0.84
* There was an apparent loss of nitrogen during the sampling year. This
may have been due to nitrogen fixation in the lake, solubilization of
previously sedimented nitrogen, recharge with nitrogen-rich ground
water, unknown and unsampled point sources discharging directly to the
lake, underestimation of the nitrogen loads from the ungaged drainage
and/or septic tanks, or (probably) insufficient outlet sampling in
relation to the short hydraulic retention time of the lake. Whatever
the cause, a similar nitrogen loss has occurred at Shagawa Lake, Minne-
sota, which has been intensively studied by EPA's former National Eutro-
phication and Lake Restoration Branch (Malueg et al., 1975).
