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 [§303(e)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [§106 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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data and a report by others (Ketelle and Uttormark,
1971) Indicate that the Fox Chain of Lakas (Marie, Grass, Fox,
and Plstakee) is eutrophic. Of the 31 Illinois lakes sampled
1n 1973, Lake Marie ranked fifteenth, Pistakee Lake ranked
eighteenth, Grass Lake ranked twentieth, and Fox Lake ranked
twenty-sixth when compared using a combination of six parameters*.
1. Lake Marie - Twelve lakes had less median total phosphorus,
16 had less and one had the same median dissolved phosphorus,
nine had less median inorganic nitrogen, 19 had less mean
chlorophyll a^, and eight had greater mean Secchi disc transparency.
Survey limnologists noted emergent aquatic vegetation at the outlet
and along the shoreline and observed heavy algal blooms. Near-
depletion of dissolved oxygen occurred with depth at station 1
in August. Chlorophyll a. concentrations increased more than
four-fold from the spring to fall sampling along with increased
numbers of blue-green algae.
2. Grass Lake - Twenty-five lakes had less median total and
dissolved phosphorus, 14 had less median inorganic nitrogen.
* See Appendix A.
-------
27 had less mean chlorophyll a., and 15 had greater mean Secchi
disc transparency. Chlorophyll ^concentrations Increased
more than five-fold from the spring to the summer.
Survey limnologlsts noted emergent aquatic vegetation along
much of the shoreline.
3. Fox Lake - Twenty-three of the lakes had less median total
phosphorus, 24 had less median dissolved phosphorus, 11 had
less median inorganic nitrogen, 25 had less mean chlorophyll a_,
and 25 had greater mean Secchi disc transparency. No surface
algae or higher aquatic plants were observed by Survey limnolo-
glsts, but chlorophyll a^ concentrations and numbers of blue-
green algae increased substantially during the summer.
4. Pistakee Lake - Twenty-two lakes had less median total
phosphorus, 20 had less and one had the same median dissolved
phosphorus, nine had less and one had the same median inorganic
nitrogen, 26 had less mean chlorophyll a_, and 23 had greater
mean Secchi disc transparency. Survey limnologists did not
observe any aquatic vegetation; however, chlorophyll a. concen-
trations increased more than two-fold from the spring to summer
along with increased numbers of blue-green algae.
B. Rate-Limiting Nutrient:
The algal assay results are not considered indicative of
conditions present in the lakes because of significant nutrient
-------
losses that occurred in the samples during shipment from the
field to the laboratory. However, the lake data indicate that
all four lakes were limited by nitrogen during most of the
growing season.
C. Nutrient Controllability:
1. Point sourcesThe mean annual contribution from listed
point sources was 13.3% of the total phosphorus input to the Fox
Chain of Lakes. The wastewater treatment plant at Burlington,
Wisconsin (see map, page vi), and the Fox Lake plant contributed
an estimated 5.1% and 2.7% of this total, respectively. The
Antioch plant contributed 3.1% and the remaining point sources
collectively contributed 2.3% of the total.
A number of additional point sources discharge to Long Lake
and to its outlet, Squaw Creek (see Working Paper No. 309,
"Report on Long Lake"). To some extent, these sources con-
tribute to the total phosphorus load of Squaw Creek as indi-
cated by the high phosphorus export rate of 92 kg/km2/yr (see
page 24) and thus contribute to the Fox Chain of Lakes nutrient
load. These point sources are not included in this report
because of the difficulty in accurately estimating the portion
of the phosphorus load retained in Long Lake and the portion
contributed to Squaw Creek. For this reason, the phosphorus
contribution attributed to point sources probably is too low.
-------
The present loading rate of 8.10 g/m2/yr is more than 12
times the rate proposed by Vollenwelder (Vollenweider and
Dillon, 1974) as a eutrophic rate (see page 24). Although
Vollenweider's model may not be applicable to lakes with
short hydraulic retention times, there is little doubt that
the phosphorus load is excessive as shown by the abundant
growths of macrophytes and blue-green algae. For this reason,
all phosphorus loads from known point sources should be
minimized to reduce the present rate of eutrophication. A
100% reduction of the phosphorus from the listed point sources
would reduce the present loading rate to 7.02 g/m2/yr. Removal
of phosphorus from additional point sources9 such as those
impacting Long Lake, would further reduce the loading rate and
should at least slow the rate of eutrophication now occurring.
In additions the relatively short mean hydraulic retention time
of the Fox Chain of Lakes (23 days) would facilitate water
quality improvement once phosphorus controls have been initiated.
2. Non-point sources--Non-point sources accounted for 86.4%
of the total phosphorus load reaching the Fox Chain of Lakes
during the sampling year. The Fox River contributed 61.6% and
Nippersink Creek contributed 12.8% of the total. The remaining
tributaries collectively contributed 7.8%, Ungaged tributaries
were estimated to have contributed 4.0% of the total.
-------
Sequoit Creek and Squaw Creek had very high export rates
of 104 kg and 92 kg P/km2/yr, respectively. The Fox River
export rate of 45 kg P/km2/yr may be slightly above average.
The high export rate of Sequoit Creek may be due to unknown
point sources, and the Squaw Creek rate is influenced by point
sources as discussed above.

III. LAKE WATER QUALITY SUMMARY
Marie, Grass, Fox, and Pistakee lakes were sampled three times during
the open-water season of 1973 by means of a pontoon-equipped Huey heli-
copter. Each time, samples for physical and chemical parameters were
collected from two stations on each lake and from one 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, 18.9-liter depth-integrated samples were 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 in Lake Marie were 6.1 meters at station 1 and 1.2 meters at
station 2; in Grass Lake, 0.6 meters at station 1 and 0.6 meters at
station 2; in Fox Lake, 1.5 meters at station 1 and 4.0 meters at sta-
tion 2; and in Pistakee Lake, 2.1 meters at station 1 and 2.1 meters at
station 2.
The lake sampling results are presented in full in Appendix D and
are summarized in the following tables.

C. Limiting Nutrient Study:
The algal assay results for all four lakes are not considered
indicative of lake conditions at sampling time (05/09/73) because
of substantial nutrient losses in the samples during shipment
from the field to the laboratory. However, the lake data indicate
that all four lakes were nitrogen limited during the sampling year
-------
18
at all stations with two exceptions. Following is a tabulation
of the mean inorganic nitrogen to orthophosphorus ratios for each
of the stations and sampling times with indicated limiting nu-
trient in parentheses.

Nitrogen limitation, as indicated by the algal assay or by
in-lake nitrogen to phosphorus ratios, does not necessarily
suggest that the trophic condition of the lake can be improved
by controlling nitrogen inputs. In the majority of cases,
phosphorus is still the element to be controlled. The apparent
condition of nitrogen-limitation frequently results from excessive
phosphorus input from point sources and is often accompanied by a
corresponding increase in primary production. The reversal of the
enriched condition, therefore, depends upon phosphorus control,
not nitrogen control.

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 maps (pages v and v1), except for the
high runoff months of March and April when two samples were collected.
Sampling was begun in June, 1973, and was completed in April, 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/km2/year, in Nippersink Creek at station 33A-1 and multiplying
by the ZZ area in km2.
The operators of the Antioch, Hebron Municipal, and Hebron Indus-
trial wastewater treatment plants provided monthly effluent samples
and corresponding flow data. However, Fox Lake Village, Richmond,
* See Working Paper No. 175.
-------
20
Burlington, and Silver Lake did not participate in the sampling program,
and nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/year.
A number of wastewater treatment plants impact nearby Long Lake
through discharge to its tributaries. Therefore, a portion of the Squaw
Creek outlet nutrient loads is contributed by these point sources and
also enters the Fox Chain of Lakes at Fox Lake. However, it is difficult
to accurately calculate the load due to these point sources (see Working
Paper No. 309, "Report on Long Lake"). Consequently, the entire nutrient
loads measured in Squaw Creek at station A-l are included as non-point
loads.
Separate nutrient loadings could not be calculated for each of the
four lakes in this report because no flow measurements were provided
for the sampling points between the lakes. A total nutrient load was
calculated for all four lakes however, and this provides an overall
view of point-source impact on the Fox Chain of Lakes.

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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/mVyr 8.10 0.58 104.9 7.0
Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Fox Chain of
Lakes*:
"Dangerous" (eutrophic rate) 0.64
"Permissible" (oligotrophic rate) 0.32
* Based on morphometry of all four lakes.
