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 Take, 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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Bass Lake is eutrophic. It ranked
twelfth in overall trophic condition when the 27 Indiana lakes
sampled in 1973 were compared using a combination of six param-
eters*. Fifteen of the lakes had less median total phosphorus,
14 had less and one had the same median dissolved phosphorus,
six had less median inorganic nitrogen, 20 had less mean chloro-
phyll a_, and 21 had greater mean Secchi disc transparency.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Bass Lake was phosphorus
limited at the time the sample was collected (05/02/73). The lake
data indicate phosphorus limitation in August as well but marginal
nitrogen limitation in October.
C. Nutrient Controllability:
1. Point sources—No known municipal or industrial point
sources impacted Bass Lake during the sampling year. Lakeshore
septic tanks were estimated to have contributed 23.7% of the
total load reaching the lake, but a shoreline survey would be
necessary to determine the significance of those sources.
* See Appendix A.
-------

The present phosphorus loading of 0.09 g/m2/yr is less
than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 11).
The trophic condition of the lake at this time may be the
result of greater nutrient loadings in the past. For example,
since the phosphorus ban was instituted in January, 1972,
there was an estimated decrease in domestic wastewater phosphorus
of about 50%. In other words, the 115 kg P/yr now estimated to
have come from septic tanks (see page 9) would have been about
230 kg P/yr before the ban. The total phosphorus loading rate
prior to the 1972 ban (assuming no other changes have taken
place in phosphorus loading) is estimated at 600 kg P/yr (0.11
g/m2/yr); i.e., 19% greater than the present load.
With a mean hydraulic retention time of three years, a lag
time of several years would be expected before improvement in the
quality of the lake becomes apparent.
2. Non-point sources—The phosphorus load from non-point
sources was estimated to have been 76.3% of the total load during
the sampling year. No gaged tributaries were sampled during the
year; the ungaged tributaries were estimated to have contributed
55.7% of the total phosphorus load.

III. LAKE WATER QUALITY SUMMARY
Bass 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 usually were collected
from two or more depths at three stations on the lake (see map, page
v). During each visit, a single depth-integrated (near bottom to sur-
*•
face) sample was composited from the stations for phytoplankton identi-
fication 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
0.6 meters at station 1, 4.9 meters at station 2, and 2.1 meters at
station 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 Bass Lake was high at the time the sample was collected
(05/02/73). The results also indicate that Bass Lake was
phosphorus limited at that time. Note that with the addition
of nitrogen alone, the yield was not significantly greater
than the control yield; however, with the addition of ortho-
phosphorus, a marked increase in yield occurred.
The lake data indicate phosphorus limitation in August
as well (the mean inorganic nitrogen/orthophosphorus ratio
was 32/1) but marginal nitrogen limitation in October (the
mean N/P ratio was nearly 13/1).

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 the outlet
site 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
outlet and minor tributaries and immediate drainage.
In this report, outlet nutrient loads were determined by using a
modification of a U.S. Geological Survey computer program for calculat-
ing stream loadings*.
Nutrient loadings for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations A-2, B-l, and C-l of nearby
Lake Maxinkuckee** and multiplying the means by the Bass Lake ZZ area in
. km2.

D. 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.
