FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration comitment 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 [ lO6 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
iii
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 KNOWLEOGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Illinois Environmental
Protection Agency for professional involvement and to the
Illinois National Guard for conducting the tributary sampling
phase of the Survey.
Dr. Richard H. Briceland, Director of the Illinois Environ-
mental Protection Agency; and Ronald M. Barganz, State Survey
Coordinator, and John J. Forneris, Manager of Region III, Field
Operations Section of the Division of Water Pollution Control,
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 Harold R. Patton, the Adjutant General of
Illinois, and Project Officer Colonel Daniel L. Fane, who directed
the volunteer efforts of the Illinois National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

SANGCHRIS LAKE
STORET NO. 1753
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Sangchris Lake is eutrophic. It
ranked sixth in overall trophic quality when the 31 Illinois
lakes sampled in 1973 were compared using a combination of six
parameters*. Three lakes had less and one had the same median
total phosphorus, one had less median dissolved phosphorus, 21
had less median inorganic nitrogen, 13 had less mean chloro-
phyll a, and ten had a greater mean Secchi disc transparency.
Marked depression of dissolved oxygen with depth occurred at
sampling stations 1 and 2 in August.
Survey limnologists noted blue-green algal concentrations
in August and rooted aquatic vegetation along about 5% of the
shoreline.
B. Rate—Limiting Nutrient:
The algal assay results indicate that Sangchris Lake was
phosphorus limited at the time the sample was collected (05/07/73).
These results are substantiated by the lake data. On all sampling
dates, the mean N/P ratios were 35/1 or greater, and limitation by
phosphorus would be expected.
* See Appendix A.
-------

C. Nutrient Controllability:
1. Point sources—-The estimated phosphorus contribution
from known point sources amounted to nearly 6.5% of the total
reaching Sangchris Lake during the sampling year, and essentially
all of the point—source input was the estimated Comonwealth
Edison Kincaid (generating) Station wastewater treatment plant
phosphorus load.
The present phosphorus loading rate of 0.38 g/m 2 /yr is just
in excess of the rate proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic rate (see page 14), and it is
calculated that removal of 80% of the phosphorus at the two
point sources included in this study would reduce the loading
to a rate just equal to the eutrophic rate. However, because
the Kincaid station phosphorus load was estimated, and because
the Tovey Pumphouse wastewater treatment plant flows also were
estimated, a more-detailed study of the point-source phosphorus
contributions to Sangchris Lake is needed to determine the
feasibility of phosphorus control.
2. Non—point sources--About 59% of the total phosphorus
input to Sangchris Lake came from gaged non-point sources during
the sampling year 0 Clear Creek (eastern) and Clear Creek (west-
ern) each contributed over 20% and the unnamed stream (D-l)
contributed nearly 10% of the total. Ungaged tributaries were
estimated to have contributed 30.2% of the total phosphorus input.
-------
In all, non-point sources, Including precipitation, were esti-
mated to have contributed over 93% of the total phosphorus load
to Sangchris Lake during the sampling year.
The phosphorus export rates of the Sangchris Lake tributaries
were relatively low and are comparable to the rates of other
unimpacted tributaries sampled 1n the Sangamon River drainage;
e.g., Panther Creek and Lick Creek (tributaries of nearby Lake
Springfield*) had phosphorus export rates of 20 and 28 kg/km2/yr.
respectively.

III. LAKE WATER QUALITY SUMMARY
Sangchris 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 four
stations on the lake and from a number of depths at each station (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 a analysis. The maximum depths
sampled were 10.1 meters at station 1, 8.8 meters at station 2, 4.6
meters at station 3, and 5.5 meters at station 4.
The lake 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 Sangchris Lake was high at the time the sample was col-
lected (05/07/73). A significant increase In yield occurred
with the addition of phosphorus alone, but the addition of
nitrogen alone did not result in a significant difference in
-------
9
yield as compared to the control. Therefore, phosphorus
limitation is indicated.
The lake data further indicate phosphorus limitation.
At all sampling times, the mean ratios of inorganic nitrogen
to orthophosphorus were 35 to 1 or greater.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Illinois 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 Illinois District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined 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 means of the
nutrient loads, in kg/km 2 /year, at stations B-i, C-i, and 0-1 and
multiplying the means by the ZZ area in km 2 .
The operators of the Coninonwealth Edison Kincaid Station and Tovey
Pumphouse wastewater treatment plants provided monthly effluent samples
and flow data. However, the flow data provided for the generating

11
station included the large-volume condenser discharge, and waste
treatment plant loads could not be calculated. Consequently, nutrient
loads were estimated at 1.134 kg P and 3.401 kg N/capita/year.
Also, the flows provided for the Tovey Pumphouse treatment plant
were estimated.

Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (Vollen-
welder and Dillon, 1974). Essentially, his “dangerous” rate
is the rate at which the receiving water would become eutrophic
or remain eutrophic; his “permissible” rate is that which would
result in the receiving water remaining oligotrophic or becoming
oligotrophic if morphometry permitted. A mesotrophic rate 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.
