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, 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

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Crooked Lake is meso-eutrophic.
It ranked seventh in overall trophic quality when the 27 Indiana
lakes sampled in 1973 were compared using a combination of six
parameters*. Four lakes had less and one had the same median
total phosphorus, four had less and three had the same median
dissolved phosphorus, none had less median inorganic nitrogen,
five had less mean chlorophyll a_, and six had greater mean Secchi
disc transparency. Depletion of dissolved oxygen with depth
occurred at sampling station 2 in August and October.
Survey limnologists reported a moderate algal bloom in August
and much of the lake occupied by emergent and submerged rooted
aquatic plants in August and October.
B. Rate-Limiting Nutrient:
The algal assay results indicate Crooked Lake was phosphorus
limited at the time the assay sample was collected (05/02/73).
The lake data indicate phosphorus limitation at all sampling
times.
C. Nutrient Controllability:
1. Point sources—No known municipal or industrial wastewater
treatment plants impacted Crooked Lake during the sampling year.
* See Appendix A.
-------
2
Septic tanks serving Takeshore dwellings contributed an estimated
6.5% of the total phosphorus load, but a shoreline survey would
be needed to determine the significance of these sources.
The non-point source phosphorus export of the Center Lake
outlet was substantially higher than would be expected; and
it is possible that urban drainage in the Angola metropolitan
\
vicinity contributed to the phosphorus load in this stream via
marshes near Center Lake.
The present phosphorus loading of 0.24 g/m2/yr is a little
less than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 11). Because Crooked Lake
is phosphorus limited, all phosphorus inputs should be minimized
to the greatest practicable degree to protect the trophic quality
of this water body.
2. Non-point sources—Over 93% of the total phosphorus input
to Crooked Lake was contributed by non-point sources during the
sampling year. The Center Lake outlet contributed 50.0%; Unnamed
Stream D-l, 14.3%; and the Loon Lake outlet, 6.5% of the total
load. The ungaged tributaries were estimated to have contributed
15.6% of the total phosphorus load. As discussed above, the phos-
phorus export rate of the Center Lake outlet (49 kg/km2) was sig-
nificantly higher than the export rates of the other tributaries
in the drainage basin (see page 10). A portion of this load
probably should be attributed to point sources.

III. LAKE WATER QUALITY SUMMARY
Crooked 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 one
or more depths at three 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 ^analysis. The maximum depths sampled were 4.6
meters at station 1, 20.7 meters at station 2, and 1.5 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 Crooked Lake was moderate at the time the assay sample
was collected. The assay results also indicate phosphorus
limitation at that time. Note the lack of significant
change in yield with the addition of nitrogen alone but
the significant increase when orthophosphorus was added.
The lake data also indicate a phosphorus limitation at
all sampling times. The mean inorganic nitrogen/orthophos-
phorus ratios were 19/1 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 month of 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*. Although nutrient data for
stations A-2 and A-3 are included in Appendix E, the three basins have
been treated as a single water body.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations B-l and D-l and multiplying
the means by the II area in km2.
The estimated septic tank phosphorus loads were reduced by 50%
because of a phosphate detergent ban in effect in Indiana since 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 Ni trogen
Total Accumulated Total Accumulated
grams/m2/yr 0.24 0.19 6.5 3.5
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Crooked Lake:
"Dangerous" (eutrophic loading) 0.30
"Permissible" (oligotrophic loading) 0.15
