FOREWORD
The National Eutroph1cat1on 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.
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Long Lake is eutrophic. It ranked
29th when the 31 Illinois lakes sampled in 1973 were compared
using a combination of six parameters*. Twenty-eight of the
lakes had less median total phosphorus, 29 had less median
dissolved phosphorus, 17 had less median inorganic nitrogen, 21
had less mean chlorophyll a_, and 18 had greater mean Secchi disc
transparency.
Survey limnologists noted surface concentrations of blue-green
algae in August, 1973.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Long Lake was limited
by nitrogen at the time the sample was taken (05/09/73). The
lake data indicate nitrogen limitation in August and October as
well.
C. Nutrient Controllability:
1. Point sources—The phosphorus contribution of known
point sources accounted for 87.3% of the total load reaching
Long Lake during the sampling year. The major portion of the
* See Appendix A.
-------
load, 81.5%, was contributed by the Round Lake Sanitary District
wastewater treatment plant. The remainder came from the Village
of Lake Villa, Fremont School, Camp Hickory, and Industrial
wastewater treatment facilities.
The present loading rate of 23.66 g/m2/yr 1s nearly 29 times
that proposed by Vollenwelder (Vollenwelder and Dillon, 1974) as
a eutrophic rate (see page 13). For this reason, all phosphorus
inputs to the lake should be minimized to the greatest practicable
extent. Complete removal of phosphorus from the listed point
source loads would reduce the loading rate to 3.03 g/m2/yr and
should at least slow the present rate of eutrophication now
occurring. The relatively short mean hydraulic retention time
of 32 days would facilitate water quality improvement once phos-
phorus controls are initiated.
2. Non-point sources--The phosphorus contribution of non-
point sources amounted to 12.7% of the total load to the lake.
Squaw Creek contributed 6.6%, Eagle Creek contributed 2.5%, and
Unnamed Creek C-l contributed 2.3% of this total. Ungaged tribu-
taries were estimated to have contributed 11.6%.

III. LAKE WATER QUALITY SUMMARY
Long 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
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 ^analysis. The maximum
depths sampled were 4.9 meters at station 1 and 4.3 meters at station
2.
The lake sampling results are presented 1n full 1n Appendix D and

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Long Lake was high at the time the assay sample was col-
lected. Also, a significant increase in yield when only
nitrogen was added indicates that this lake was limited by
nitrogen at that time. Note the lack of response when only
orthophosphorus was added.
The lake data indicate Long Lake was limited by nitrogen
at the other sampling times as well. The mean inorganic
nitrogen/orthophosphorus ratios were less than 1/1 in August
and 3/1 in October.

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 most of
the tributary sites nearest the lake. However, flow estimates for Squaw
and Eagle creeks were not included. Flow rates for these tributaries
were determined by multiplying the runoff coefficient used by U.S.G.S.,
in m3/sec/km2, by the corresponding drainage areas of each creek planim-
etered by the Survey geographer.
In this report, nutrient loads for sampled tributaries were calcu-
lated using mean annual concentrations and mean annual flows. Nutrient
loads shown are those measured minus point-source loads, if any. However,
the nutrient loads measured at the Round Lake Sanitary District wastewater
treatment facility exceeded the loads measured in Unnamed Creek C-l and
the background load for this stream and the unsampled "minor tributaries
and immediate drainage" ("ZZ" of U.S.G.S.) were estimated using the means
of the nutrient loads, in kg/km2/yr, at station A-l of nearby Lake Pistakee
-------
(see map, page vi) and multiplying the means by the C-l and ZZ areas in
km2.
The operators of the Village of Lake Villa, Round Lake Sanitary
District, Travenol Labs, Inc., and Heppner Mfg. Company wastewater
treatment plants provided monthly effluent samples and corresponding
flow data. However, Camp Hickory and Fremont School did not participate
in the sampling program. Nutrient loads for these sources were estimated
at 1.134 kg P and 3.401 kg N/capita/year, and flows were estimated at
0.3785 m3/capita/day.

per year. The pond spills into Squaw Creek only during overflow from
storm runoff which goes into Lake Lure. The latter essentially is a
300-acre swamp one mile above Long Lake.

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.
