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.
-------
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

STORET NO. 1740
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Highland Silver Lake is eutrophic.
It ranked 23rd in overall trophic quality when the 31 Illinois
lakes sampled in 1973 were compared using a combination of six
lake parameters*. Twenty-four of the lakes had less median
total phosphorus, 17 had less and one had the same median dis-
solved phosphorus, and 16 had less median inorganic nitrogen;
but only mesotrophic Cedar Lake** had less mean chlorophyll a.
The relatively low concentrations of chlorophyll a at sampling
stations 1 and 2 and the high nutrient levels indicate primary
productivity probably was light-limited. Twenty-seven of the
lakes had greater mean Secchi disc transparency, and the Survey
limnologists noted that the lake was quite turbid at all sampling
times.
Marked depression of dissolved oxygen with depth occurred at
stations 1 and 2 in August, 1973 (station 3 was not sampled at
depths greater than 1.2 meters).
B. Rate-Limiting Nutrient:
The algal assay results indicate nitrogen was the limiting
nutrient at the time the sample was collected (05/07/73).
* See Appendix A.
** Working Paper No. 298.

However, the lake data indicate phosphorus limitation in
August and October; the mean N/P ratios were 18/1 and 25/1,
respectively.
C. Nutrient Controllability:
1. Point sources--The phosphorus contribution of the only
known point source, Grantfork Elementary Center, accounted for
0.9% of the total load reaching Highland Silver Lake during
the sampling year. Shoreline septic tanks were estimated to
have contributed less than 0.1%.
The present phosphorus loading rate of 3.04 g/m 2 /yr is
over five times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic rate (see page 14). However,
on the basis of Survey data, it does not appear that phosphorus
control at the Grantfork Elementary Center would result in a
significant change in the trophic condition of Highland Silver
Lake.
2. Non—point sources--The phosphorus load from non-point
sources amounted to 99.1% of the total reaching the lake during
the sampling year. The only measured tributary, Little Silver
Creek, contributed 83.5%. The ungaged drainage area was estimated
to have contributed 15.0% of the total phosphorus load.
-------
The phosphorus export rate of Little Silver Creek was 75
kg/km2/yr (page 14). This is somewhat higher than the rates
of some of the tributaries elsewhere in the Kaskaskia River
drainage; e.g., Hickory Creek (a tributary of Carlyle Reservoir*)
had a phosphorus export rate of 25 kg/km2/yr, and Raccoon Creek
(a tributary of Raccoon Lake**) had a phosphorus export rate of
36 kg/km2/yr.
The higher phosphorus export rate of Little Silver Creek
may have been due to differing land-use practices and/or urban
drainage from the village of Grantfork (1970 population = 162).

III. LAKE WATER QUALITY SUMMARY
Highland Silver 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
three stations on the lake and generally from several 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 7.3 meters at station 1, 4.6 meters at station 2,
and 1.2 meters at station 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

of Highland Silver Lake was high at the time the sample was
collected.
There was a significant increase in yield compared to
the control when only nitrogen was added (the slight in-

is indicated at the time the sample was collected (05/08/73).
The lake data Indicate phosphorus limitation in August
and October; the mean inorganic nitrogen to orthophosphorus
ratios were 18 to 1 and 25 to 1, respectively, 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 ininediate
drainage” (“ZZ” of U.S.G.S.) were estimated using the adjusted nu-
trient loads, in kg/km 2 /year, at station A—2 and multiplying by the
ZZ area in km 2 .
The operator of the Grantfork Elementary Center wastewater treat-
ment plant provided monthly effluent samples and corresponding flow
data.

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 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.
