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 oflake 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

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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Rend Lake is eutrophic. It
ranked fourth in overall trophic quality when the 31 Illinois
lakes sampled in 1973 were compared using a combination of
six parameters*. Seven lakes had less median total phosphorus,
two had less and one had the same median dissolved phosphorus,
six had less median inorganic nitrogen, 15 had less mean chloro-
phyll a, and nine had greater mean Secchi disc transparency.
Depression of dissolved oxygen with depth occurred at sampling
station 1 in August, 1973.
Survey limnologists reported emergent vegetation in the
shallows along the shorelines.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Rend Lake was phos-
phorus limited at the time the assay sample was collected
(05/08/73). The lake data indicate phosphorus limitation at
the other sampling times as well.
C. Nutrient Controllability:
1. Point sources—-The phosphorus contribution of known
point sources amounted to 20.3% of the total input to Rend

Lake during the sampling year. However, the non-point source
exports of the Big Muddy River and, particularly, Casey Fork
were substantially higher than the other streams In the drainage
basin (see page 14). It is likely that other point sources
contributed significantly to the phosphorus loads, or the
contributions from known point sources were underestimated.
The known point sources contributing to the overall phosphorus
load include Mt. Vernon (19.9%) and Dix (0.3%). Four additional
sewage treatment facilities collectively contributed 0.2% of the
total load reaching Rend Lake.
The present phosphorus loading rate of 0.97 g/m 2 /yr is over
2.5 times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 14). A 100% reduction of
the phosphorus from the known point sources would reduce the
overall loading rate to about twice the eutrophic rate; however,
because the lake is phosphorus limited, all phosphorus inputs
should be minimized to the greatest practicable extent to slow
the eutrophication of Rend Lake.
2. Non—point sources-—Nearly 80% of the total annual phos-
phorus input to Rend Lake can be attributed to non-point sources.
After accounting for the known point sources, the Big Muddy River
contributed 32.3% and Casey Fork, 31.8%. The three remaining
sampled tributaries collectively contributed 2.4% of the total.
-------
The mean annual phosphorus contribution from ungaged tribu-
taries was estimated to have been 11.Z% of the total load.
As discussed above, part of the mean annual non-point phos-
phorus exports of the Big Muddy River (45 kg/km2) and
Casey Fork (99 kg/km2) probably should be attributed to
additional point sources in the metropolitan areas rather
than to non-point sources.

III. LAKE WATER QUALITY SUMMARY
Rend 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 4.6 meters at station 1, 5.5 meters at station 2,
and 3.0 meters at stations 3 and 4.
The lake sampling results are presented in full in Appendix 0 and
are summarized in the following table.

The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that the potential primary productivity
of Rend Lake was low at the time the sample was collected
(05/08/73). The significant increase in yield with the
addition of phosphorus but the lack of yield response when
-------

only nitrogen was added indicates the lake was phosphorus
limited at that time.
The lake data further indicate phosphorus limitation.
At all sampling times, the mean inorganic nitrogen/ortho-
phosphorus ratios were 14/1 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 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 shown are
those measured minus point—source loads, if any.
Nutrient loads for unsampled “minor tributaries and iniliediate
drainage 11 (“ZZ” of U.S.G.S.) were estimated using the means of the
nutrient exports, in kg/km 2 /year, at stations 0-1, E—1, and F-l and
multiplying the means by the ZZ area in km 2 .
The operators of the Mt. Vernon and Corps of Engineers Rend Lake
Administration Area wastewater treatment plants provided monthly
effluent samples and corresponding flow data. The communities of
Dix, Woodlawn, Waltonville, and Richview did not participate in the

E. 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.

Vollenweider loading rates for phosphorus
(g/m 2 /yr) based on mean depth and mean
hydraulic retention time of Rend Lake:

“Permissible” (oligotrophic rate) 0.19
* High export value probably reflects point-source input.
