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.
-------
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, I). 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 Witmer Lake is eutrophic. Of the
27 Indiana lakes sampled in 1973, Witmer Lake ranked fifteenth
in overall trophic quality using a combination of six parameters*.
Twelve lakes had less and two had the same median total phosphorus,
12 had less and one had the same median dissolved phosphorus, 13
had less median inorganic nitrogen, 15 had less mean chlorophyll
a^, and 13 had greater mean Secchi disc transparency.
Survey limnologists noted algal blooms at both stations in
August and October, and dissolved oxygen was depleted in the
hypolimnion at both stations at those times.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Witmer Lake was phos-
phorus limited at the time the assay sample was collected (05/03/73).
However, the lake data indicate nitrogen limitation in August and
October.
C. Nutrient Controllability:
1. Point sources--During the sampling year, Witmer Lake
received a total phosphorus loading nearly 2% times that proposed
by Vollenweider (Vollenweider and Dillon, 1974) as a eutrophic
* See Appendix A.
-------
2
loading (see page 11). The only known point source, Wolcott-
ville, contributed just over 8% of the total phosphorus load.
While even complete removal of phosphorus at the Wolcott-
ville wastewater treatment plant would still leave a loading
about twice the eutrophic loadings it is possible that a high
degree of phosphorus removal at this source would result in
persistent phosphorus limitation (see page 7) and a reduction
in the incidence and severity of nuisance algal blooms. Also,
phosphorus control might benefit downstream Westler Lake (see
map, page v). Note that 67% of the phosphorus load to Witmer
Lake was not retained and moved on into Westler Lake. Dallas
Lake, just downstream from Westler Lake, probably would bene-
fit also.
2. Non-point sources—During the sampling year, the non-
point phosphorus contributions of the Witmer Lake tributaries
and immediate drainage accounted for just over 90% of the total
phosphorus load to the lake. However, the phosphorus exports
of the gaged tributaries do not appear to be excessive (see
page 10).

III. LAKE WATER QUALITY SUMMARY
Witmer 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 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 ^analysis. The maximum depths sampled were 11.6
meters at station 1 and 14.9 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 Witmer Lake was high at the time the assay sample was
collected (05/03/73). The results also indicate that the
lake was phosphorus limited. Note the lack of increase in
the yield when only nitrogen was added; but, when ortho-
phosphorus alone was added, the yield was doubled.
The lake data also indicate phosphorus limitation in
May (the mean inorganic nitrogen/orthophosphorus ratio
was 120/1) but nitrogen limitation in August and October
(the mean N/P ratios were 9/1 and 10/1, respectively).

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 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 nutrient loads,
in kg/km2/year, at station C-l and multiplying by the ZZ area in km2.
The operator of the Wolcottville wastewater treatment plant provided
monthly effluent samples and corresponding flow data.
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.
