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 [ 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

LAKE SPRINGFIELD
STORET NO. 1742
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Springfield is eutrophic.
It ranked seventeenth in overall trophic quality when the 31
Illinois lakes sampled in 1973 were compared using a combina-
tion of six parameters*. Fourteen lakes had less median total
phosphorus, 19 had less median dissolved phosphorus, 24 had
less median inorganic nitrogen, eight had less mean chloro-
phyll a, and 20 had greater mean Secchi disc transparency.
Depression of dissolved oxygen with depth occurred at sampling
station 4 in August and October and at station 5 in August.
Survey limnologists noted some blue-green algae along the
shoreline near station 5 in October and reported the occurrence
of many patches of emergent macrophytes near the other sampling
stations in August and October.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Springfield was
phosphorus limited at the time the sample was collected (05/07/73).
This finding is substantiated by the lake data (the mean N/P ratios
were 26/1 or greater at all sampling times).
*See Appendix A.

C. Nutrient Controllability:
1. Point sources—-The phosphorus contribution of known
point sources amounted to 27.7% of the total load reaching Lake
Springfield during the sampling year. However, the non—point
source export of Polecat Creek (see page 14) was substantially
higher than the other streams in the drainage basin; and it is
likely that other point sources (e.g., Chatham) contributed
significantly to the phosphorus load to Lake Springfield.
The known point sources which contributed to the overall
phosphrous load include Glenwood High School (13.1%), Virden
(7.8%), Auburn (6.5%), and Thayer Corniiunity School (0.3%).
The present phosphorus loading rate of 1 .70 g/m 2 /yr is
over three times the rate proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic rate (see page 14). A 100%
reduction in phosphorus loads from the above point sources
would only reduce the overall loading rate to 1.23 g/m 2 /yr
(about twice the eutrophic rate). However, because the lake
is phosphorus limited, all phosphorus inputs should be mini-
mized to the greatest practicable extent to slow the eutrophi-
cation of Lake Springfield.
2. Non-point sources--About 72% of the total annual phos-
phorus input to Lake Springfield is attributed to non-point
sources. After accounting for the point sources, Sugar Creek
-------
contributed 23.2%; Lick Creek, 31.2%; Polecat Creek, 6.4%;
and Panther Creek, 4.2% of the total phosphorus input.
Ungaged tributaries were estimated to have contributed 6.3% of
the total load.
As discussed above, the high non-point phosphorus export
of Polecat Creek (98 kg/km2/yr) may, in part, be attributable
to point sources (e.g., Chatham) rather than to non-point
source contributions.

III. LAKE WATER QUALITY SUMMARY
Lake Springfield 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 five stations on the lake and from two or more 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 1.5 meters at station 1, 1.8 meters at station 2,
3.4 meters at station 3, 5.5 meters at station 4, and 6.1 meters at
station 5.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

with the addition of orthophosphorus alone, but the addition
of only nitrogen did not result in a significant difference
in yield as compared to the control . Therefore, phosphorus
limitation is indicated.
The lake data also indicate phosphorus limitation. At
all sampling times, the ratios of inorganic nitrogen to ortho-
phosphorus were 26 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 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 nutrient loads,
in kg/km 2 /year, at station B-l and multiplying by the ZZ area in km 2 .
The operator of the Auburn wastewater treatment plant provided
monthly effluent samples and corresponding flow data. The treatment
plant operators of Virden, Thayer Community School, and Glenwood High

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 Volleriweider’s model may not be applicable to
water bodies with short hydraulic retention times.
