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 [ 5303(c)], clean lakes [ 5314(a,b)],
and water quality monitoring [ 5106 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.
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 WEE-MA-TUK
STORET NO. 1761
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Wee-Ma—Tuk is eutrophic.
It ranked seventh in overall trophic quality when the 31
Illinois lakes sampled in 1973 were compared using a combi-
nation of six parameters*. Six of the lakes had less median
total phosphorus, 13 had less median dissolved phosphorus,
20 had less median inorganic nitrogen, three had less mean
chlorophyll a, and seven had greater mean Secchi disc trans-
parency. Dissolved oxygen was depleted at the 6.1-meter depth
at sampling station 1 in August and October and was depressed
with depth at station 2 in August.
Survey limnologists reported some rooted emergent vege-
tation in shallow areas.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Wee—Ma—Tuk
was phosphorus limited at the time the sample was collected
(05/11/73). The lake data indicate phosphorus limitation at
the other sampling times as well (the mean N/P ratios were
25/1 or greater).
* See Appendix A.

C. Nutrient Controllability:
1. Point sources--The Wee-Ma-Tuk Country Club was the
only known point source impacting Lake Wee-Ma-Tuk during
the sampling year and contributed an estimated 9.4% of the
total phosphorus load. Other possible point source contri-
butions would be from septic tanks serving lakeshore dwellings,
but the significance of these sources was not determined.
The present phosphorus loading rate of 0.61 g/m 2 /yr is
about 1.5 times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic rate (see page 12). For this
reason, and because Lake Wee-Ma-Tuk is phosphorus limited,
all phosphorus inputs should be minimized to the greatest
practicable extent to slow the eutrophication of this water
body.
2. Non-point sources--The total phosphorus contributions
of non-point sources amounted to 90.6% of the total load during
the sampling year. Put Creek contributed 33.7%, and the ungaged
tributaries were estimated to have contributed 54.2% of the
total load.
The phosphorus export rate of Put Creek was a relatively
low 27 kg/kni 2 /yr (see page 12).

III. LAKE WATER QUALITY SUMMARY
Lake Wee-Ma-Tuk 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 two 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 6.1 meters at station 1 and 4.3 meters at station 2.
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 Lake Wee-Ma-Tuk was low at the time the sample was col-
lected (05/11/73). A significant increase in yield
occurred with the addition of phosphorus alone, but the
addition of nitrogen alone did not result in an increase;
hence, phosphorus limitation is indicated.
The lake data indicate limitation by phosphorus at all
sampling times; i.e., the mean inorganic nitrogen/orthophos—
phorus ratios were 25/1 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 months of January 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 irinediate
drainage” (“ZZ” of U.S.G.S.) were estimated using the nutrient exports,
in kg/km 2 /year, at station A-2 and multiplying by the ZZ area in km 2 .
The Wee-Ma-Tuk Country Club 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 Vollenwelder (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 Vollenwelder’s model may not be applicable to
water bodies with short hydraulic retention times.

Total Accumulated Total Accumulated
grams/m 2 /yr 0.61 0.32 24.6 8.5
Vollenweider loading rates for phosphorus
(g/m 2 /yr) based on mean depth and mean
hydraulic retention time of Lake Wee-Ma-Tuk:
