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 3O5(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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Lake Vermilion is eutrophic. It
ranked 24th in overall trophic quality when the 31 Illinois
lakes sampled in 1973 were compared using an index of six
pararneters*. Fifteen of the lakes had less median total
phosphorus, 16 had less median dissolved phosphorus, 29 had
less median inorganic nitrogen, 17 had less mean chlorophyll
a, and 16 had greater mean Secchi disc transparency. Marked
depression of dissolved oxygen with depth occurred at sampling
station 1 in August.
Survey limnologists noted moderate turbidity (1% light pene-
tration ranged from 0.4-1.5 m) during all sampling periods, and
emergent vegetation was observed in the shallow areas near
station 2.
B. Rate—Limiting Nutrient:
A significant loss of phosphorus occurred in the assay
sample from the time of collection to the beginning of the
assay, and the results are not indicative of conditions in
the lake at the time the sample was taken (05/11/73).
* See Appendix A.
-------

However, the mean concentration of orthophosphorus in the
lake at that time indicates a probable high level of potential
primary productivity.
The lake data indicate phosphorus limitation at all samp-
ling times.
C. Nutrient Controllability:
1. Point sources--The estimated phosphorus contribution
of known point sources, including septic tanks, amounted to
31.2% of the total load to Lake Vermilion during the sampling
year. The City of Hoopeston contributed 30.5%, and Rossville
septic tanks contributed 0.7% of the total.
The present phosphorus loading rate of 10.20 g/m 2 /yr is
seven times that proposed by Vollenwider (Vollenweider and
Dillon, 1974) as a eutrophic rate (see page 14). However, the
mean hydraulic retention time of Lake Vermilion is a short nine
days, and Vollenweider’s model probably is not applicable.
Nonetheless, the trophic condition of the lake is evidence of
excessive nutrient loads, and all phosphorus inputs should be
minimized to the greatest practicable extent.
2. Non-point sources-—The North Fork, Vermilion River was
estimated to have contributed 62.4% of the total phosphorus
load reaching Lake Vermilion during the sampling year. The
ungaged drainage area was estimated to have contributed 6.3%
of the total.
-------
The phosphorus export rate of the North Fork, Vermilion
River compares well with the rates of five tributaries of
nearby Lake Decatur* (mean of 35 kg/km2/yr; range of 31 to
41 kg/km2/yr) but was somewhat higher than most of the
tributaries sampled for land-use studies (see page 13).

III. LAKE WATER QUALITY SUMMARY
Lake Vermilion 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 one or more depths at each station (see
map, page v). During each visit, a single depth-integrated (near
bottom to surface) sample was composited from the two 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 and 0.9 meters at station 2.
The results obtained are presented in full in Appendix D and are
summarized in the following table.

C. Limiting Nutrient Study:
An 80% loss of orthophosphorus occurred In the assay
sample from the time of collection to the beginning of the
assay, and the results are not indicative of lake conditions
at the time the sample was collected (05/11/73). However,
the mean concentration of phosphorus in the lake at the time
of collection (0.054 mg/l) indicates a probable high level
of potential primary productivity.
The lake data indicate phosphorus limitation at all
sampling times; the mean inorganic nitrogen/orthophosphorus
ratios were 24/1 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 “nornialized” 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.
Nutrient loads for unsampled “minor tributaries and immediate
drainage” (“ZZ” of U.S.G.S.) were estimated by using the means of the
nutrient loads, in kg/km 2 /year, at stations B-i, C-i, D-l, E-i, F-l,
and G—1 (see page 13) and multiplying the means by the ZZ area in km 2 .
The City of Hoopeston did not participate in the Survey, and
nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/year.
The Village of Rossville has no municipal system and is served by
septic tanks.

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.
