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 { 3O3(e)}, water
quality criteria/standards review { 3O3(c)}, clean lakes { 3l4(a,b)},
and water quality monitoring [ 1O6 and §305(b)} activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.

-------
111
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.
AC KNOWLEDGMENT
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

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Maxinkuckee Is mesotrophic.
It ranked fifth in overall trophic quality when the 27 Indiana
lakes sampled in 1973 were compared using a combination of six
parameters*. Six of the lakes had less median total phosphorus,
none of the others had less but two had the same median dissolved
phosphorus, five had less median inorganic nitrogen, four had less
mean chlorophyll a, and four had greater mean Secchi disc trans-
parency. Depletion of hypolimnetic dissolved oxygen occurred at
station 1 in August.
Survey lithnologists reported submerged macrophytes at station
2 in August and October and sparse growths at station 1 in October.
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 in August as well but probable nitrogen limi-
tation in October.
C. Nutrient Controllability:
1. Point sources--No known municipal or industrial point
sources impacted Lake Maxinkuckee during the sampling year. Lake-
shore septic tanks were estimated to have contributed 3.5% of the
* See Appendix A.

total phosphorus load but a shoreline survey would be necessary
to determine the significance of those sources.
The relatively small septic tank load Is In agreement with an
earlier evaluation of the impact of septic tanks on the lake
prior to Indiana’s phosphate detergent ban (Hamelink, 1971). How-
ever, these sources are potentially dangerous considering the num-
ber of people that could inhabit the existing shoreline dwellings.
Hamel ink (op. cit.) estimated that about 20% of the dwellings were
occupied by full-time residents. Although the threat posed by
expected growth was considered minimal by Hamelink, the associated
activities (i.e., boating, fishing, fertilizing of lawns on the
lakeshore, etc.) would be expected to greatly increase the phosphorus
loading to the lake.
The present phosphorus loading of 0.15 g/m 2 /yr is less than
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading but is more than his oligotrophic loading;
i.e., a mesotrophic loading (see page 12). However, all phosphorus
inputs to the lake should be minimized to the greatest practicable
degree since only a 30% increase in the existing loading would
result in a eutrophic loading.
2. Non-point sources--The three gaged tributaries accounted
for about 56% of the total phosphorus load reaching the lake
during the sampling year. Unnamed Creek B-l contributed 26.8%;
Curtiss Ditch, 20.8%; and Wilson Ditch contributed 8.7% of the
total load.

-------
3
The ungaged ininediate drainage area was estimated to have
contributed 29.0%. The phosphorus load from this source may even
be more significant because of the use of fertilizers on lake-
shore lawns (Hamelink, op. cit.).

III. LAKE WATER QUALITY SUMMARY
Lake Maxinkuckee 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 coinposited 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 12.2 meters at station 1 and 12.8 meters at station 2.
The sampling results are presented in full in Appendix D and are
sumarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that the potential primary productivity
of Lake Maxinkuckee was low at the time the sample was col-
lected (05/02/73). There was a significant increase in yield
when orthophosphorus was increased, but there was no change in
yield when only nitrogen was added. These results indicate
phosphorus limitation.
The lake data indicate phosphorus limitation in August
as well (the mean inorganic nitrogen/orthophosphorus ratio
was 49/1). However, the data indicate probable nitrogen limi-
tation 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*.
Nutrient loads for unsampled “minor tributaries and inii ediate
drainage” (“ZZ” of U.S.G.S .) were estimated using the means of the
nutrient loads at stations A-2, B-l, and C-i, in kg/km 2 /year , and
multiplying the means by the ZZ area in km 2 .
Note that the estimated phosphorus load from septic tanks was
reduced by 50% to adjust for the phosphate detergent ban 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 nieso-
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 Nitrqgen
Total Accumulated Total Accumulated
grams/m 2 /yr 0.15 0.13 5.6 4.5
Vollenweider phosphorus loadings
(g/m 2 /yr) based on mean depth and mean
