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.
OBJECT I VES
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 [ 5303(c)], clean lakes [ 53l4(a,b)],
and water quality monitoring [ 5106 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.
ACKNOWLEDGMENT
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.

LAKE LOU YAEGER
STORET NO. 1726
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Lou Yaeger is eutrophic.
It ranked 21st when the 31 Illinois lakes sampled in 1973 were
compared using a combination of six parameters*. Twenty-one
lakes had less median total phosphorus, 23 had less median
dissolved phosphorus, 19 had less median inorganic nitrogen,
but only four had less mean chlorophyll a. The relatively low
mean chlorophyll a and the high nutrient levels indicate
primary productivity probably was light-limited. Twenty-eight
of the lakes had greater mean Secchi disc transparency, and
Survey limnologists noted that the lake was very turbid at
all sampling times.
B. Rate-Limiting Nutrient:
The algal assay results are not considered representative
of conditions in the lake because of a significant change in
nutrient concentrations in the sample between the time of
collection and the beginning of the assay.
However, the lake data indicate phosphorus was the limiting
nutrient at all sampling times.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources-—The phosphorus load from the only known
point source, the Village of Raymond, amounted to 5.5% of the
total reaching the lake during the sampling year. The present
phosphorus loading rate of 3.15 g/m 2 /yr is a little over five
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 12). Even complete removal
of phosphorus at Raymond would still leave a loading rate nearly
five times the eutrophic rate, and it appears that point—source
phosphorus control would not appreciably improve the trophic
condition of Lake Lou Yaeger.
2. Non-point sources-—The three gaged tributaries, Three
Mile Creek (37.6%), West Fork, Shoal Creek (29.9%), and Blue
Grass Creek (10.7%), contributed a total of 78.2% of the
annual non-point phosphorus load. The ungaged drainage areas
were estimated to have contributed 15.8%.
The phosphorus export rates of the three tributaries ranged
from 39 to 73 kg/km 2 /yr with a mean of 61 kg/km 2 /yr (see page
12). Two of the three tributaries have export rates that appear
to be somewhat high compared to the rates of four unimpacted
tributaries of nearby Lake Vandalia* (mean = 42 kg/km 2 /yr; range
of 34 to 58 kg/km 2 /yr), but this may be due to differences in
land-use practices in the two lake drainages.

III. LAKE WATER QUALITY SUMMARY
Lake Lou Yaeger 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 6.7 meters at station 1, 6.7 meters at station 2,
3.0 meters at station 3, and 2.4 meters at station 4.
The lake sampling results are presented in full in Appendix 0 and
are summarized in the following table.

C. Limiting Nutrient Study:
There was more than a 30% change in nutrient levels in the
assay sample from the time of collection to the beginning of
the assay, and the results are not representative of conditions
in the lake at the time the sample was collected.
The lake data indicate phosphorus limitation at all sampling
times, i.e., the mean inorganic nitrogen/orthophosphorus ratios
were 16/1 or greater, and phosphorus limitation would be expected.

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 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 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 shown are
those measured minus point-source loads, if any.
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 and C-i and multiply-
ing the means by the ZZ area in km 2 .
The Village of Raymond did not participate in the Survey, and
nutrient loads were estimated at 1 .134 kg P and 3.401 kg N/capita/year.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (Vollen-
weider 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 morphonietry 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.
