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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Dallas Lake is eutrophic. Of the
27 lakes sampled in Indiana in 1973, Dallas Lake ranked tenth in
overall trophic quality using a combination of six parameters*.
Ten of the lakes had less median total phosphorus, 18 had less
median dissolved phosphorus, 11 had less median inorganic nitrogen,
eight had less mean chlorophyll a^ and eight had greater mean Secchi
disc transparency. Near-depletion or depletion of dissolved oxygen
occurred in the hypolimnion at both stations in August and October.
Survey limnologists noted light algal blooms and emergent and
submerged macrophytes.
B. Rate-Limiting Nutrient:
The algal assay results show that Dallas Lake was phosphorus
limited at the time the assay sample was collected (05/04/73). The
lake data indicate phosphorus limitation in August as well but nitro-
gen limitation in October.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Dallas Lake received
a total phosphorus loading just over 1% times that proposed by Vollen-
weider (Vollenweider and Dillon, 1974) as a eutrophic loading. The
* See Appendix A.
-------
2
only known direct point source, Whetzel High School, is estimated
to have contributed 16.4% of the total phosphorus load.
An indirect point source, the Village of Wolcottville, impacts
upstream Witmer Lake; and, considering the relatively small phos-
phorus retention in the intervening water bodies (less than 33% in
Witmer Lake and less than 12%-in Westler Lake), this source prob-
ably impacts Dallas Lake as well.
While even complete removal of phosphorus at the Whetzel High
School treatment plant would still leave a loading of about 1.3
g/m2/yr (0.3 g/m2/yr in excess of the eutrophic loading), if a high
degree of phosphorus removal is provided at the High School plant
and at the Wolcottville plant, it is likely to result in persistent
phosphorus limitation in Dallas Lake (see page 7) and a reduction in
the incidence and severity of nuisance algal blooms.
2. Non-point sources—During the sampling year, the non-point
phosphorus contributions of the\ Westler Lake outlet and the immediate
drainage accounted for nearly 82% of the total phosphorus load to
Dallas Lake.

III. LAKE WATER QUALITY SUMMARY
Dallas 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 a^ analysis. The maximum depths sampled were 28.6
meters at station 1 and 21.3 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 Dallas Lake was moderately high at the time the assay
sample was collected (05/04/73). The results also indicate
phosphorus limitation at that time. Note the four-fold
increase in yield with the addition of orthophosphorus alone
and the lack of a significant increase in yield with the
addition of only nitrogen.
The lake data indicate phosphorus limitation in August
as well (the mean inorganic nitrogen/orthophosphorus ratio
was 16/1); however, the mean N/P ratio in October was 9/1,
and nitrogen 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 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 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.
The operator of the Whetzel High School wastewater treatment plant
did not participate in the Survey, and nutrient loads were estimated
at 0.567 kg P and 3.401 kg N/capita/year (note that the per-capita
estimate for phosphorus 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.
