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 VANDALIA
STORET NO. 1764
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Vandalia is eutrophic. Of
the 31 Illinois water bodies sampled in 1973, Lake Vandalia
ranked thirteenth in overall trophic quality based on an index
of six pararneters*. Sixteen of the lakes had less median total
phosphorus, 12 had less median dissolved phosphorus, 12 had less
median inorganic nitrogen, five had less mean chlorophyll a, and
12 had greater mean Secchi disc transparency. Marked depression
of dissolved oxygen with depth occurred at sampling station 1 at
all three sampling times and at station 2 in August, 1973.
Survey limnologists did not observe any nuisance conditions
during their visits to the lake.
B. Rate—Limiting Nutrient:
The algal assay results indicate Lake Vandalia was phosphorus
limited at the time the assay sample was collected (05/11/73).
The lake data indicate phosphorus limitation at the other samp-
ling times as well.
C. Nutrient Controllability:
1. Point sources--The Fayette County Nursing Home was the only
known point source impacting Lake Vandalia during the sampling year
* See Appendix A.

and is estimated to have contributed 3.5% of the total
phosphorus load.
The present phosphorus loading rate of 0.96 g/m 2 /yr
(see page 13) is more than two times that proposed by
Vollenweider (Vollenwejder and Dillon, 1974) as a eutrophic
rate. Therefore, all phosphorus inputs should be minimized
to the greatest practicable extent.
2. Non-point sources--The gaged tributaries of Lake Vandal ía
contributed 44.9% of the total phosphorus loading. The minor
tributaries and immediate drainage were estimated to have con-
tributed 49.6% of the total load.
The phosphorus export rates of the tributaries (see page 13)
are comparable to the rates of other unimpacted streams elsewhere
in the Kaskaskia River drainage; e.g., the export rate of Blue
Grass Creek (a tributary of nearby Lake LOU Yaeger*) was 39
kg/km 2 during the Survey sampling year.

III. LAKE WATER QUALITY SUMMARY
Lake Vandalia 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 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 a analysis. The maximum depths
sampled were 9.8 meters at station 1, 4.0 meters at station 2, and 1.2
meters at station 3.
The results obtained are presented in full in Appendix D and are
summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that the potential primary productivity
of Lake Vandalia was high at the time the assay sample was
collected (05/11/73). The results also indicate that the
lake was phosphorus limited at that time. Note the lack of
a significant increase in yield with the addition of nitrogen
only, but the addition of orthophosphorus alone or in combina-
tion with nitrogen resulted in a marked yield increase.

The lake data indicate phosphorus limitation at the
other sampling times as well. The inorganic nitrogen to
orthophosphorus ratio was 22 to 1 in August and in October,
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 “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 means of the
nutrient loads, in kg/km 2 /year, at stations A-2, B—l, and C- i and
multiplying the means by the ZZ area in km 2 .
The Fayette County Nursing Home did not participate in the Survey,
and nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capital
year.

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 0.96 0.12 11.0 0.7
Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Lake Vandalia:
"Dangerous" (eutrophic rate) 0.42
"Permissible" (oligotrophic rate) 0.21
