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 show that Crab Orchard Lake Is eutrophic. It
ranked eighth in overall trophic quality when the 31 Illinois
lakes sampled in 1973 were compared using a combination of six
lake parameters*. Ten of the lakes had less median total phos-
phorus, four had less and one had the same median dissolved
phosphorus, two had less and one had the same median inorganic
nitrogen, 24 had less mean chlorophyll a_, and 17 had greater
mean Secchi disc transparency. Marked depression of dissolved
oxygen with depth occurred at sampling station 1 in August,
1973.
Survey limnologists reported a blue-green algal bloom in
progress in August and noted the occurrence of submergent and
emergent aquatic macrophytes in the shoreline shallows near
all three sampling stations.
B. Rate-Limiting Nutrient:
A significant change in primary nutrients occurred in the
assay sample between the time of collection and the beginning
of the assay, and the results are not representative of condi-
tions in the lake at the time the sample was taken (05/08/73).
* See Appendix A.
-------
The lake data indicate phosphorus limitation in May but
nitrogen limitation in August and October.
C. Nutrient Controllability:
1. Point sources—The estimated phosphorus contribution
of point sources amounted to 26.3% of the total load reaching
the lake during the sampling year. The City of Marion was
estimated to have contributed 20.3% and the other four point
sources 6.0% of the total load.
The Crab Orchard National Wildlife Refuge provides a winter-
ing area for a large segment of the Mississippi flyway Canada
goose flock as well as many flyway ducks, and it is estimated
that ducks and geese contributed 7.9% of the total phosphorus
load to Crab Orchard Lake during the sampling year (see page
10).
The present phosphorus loading rate of 2.82 g/m2/yr is over
seven times that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic rate (see page 14). Even complete
removal of phosphorus at the point sources would only reduce
the loading rate to 2.07 g/m2/yr (still over five times the
dangerous rate). However, Crab Orchard Lake is phosphorus
limited part of the time, and it is likely that a high degree
of phosphorus control at the point sources would result in
-------
persistent phosphorus limitation and a reduction in the
Incidence and severity of nuisance algal blooms, particularly
if a significant portion of the phosphorus export of Crab
Orchard Creek proves to be controllable (see below).
2. Non-point sources—It is estimated that non-point
sources accounted for 65.8% of the total phosphorus load
reaching Crab Orchard Lake during the sampling year. However,
Crab Orchard Creek had a very high phosphorus export rate of
221 kg/km2/yr (see page 14).
It 1s unlikely that the high rate resulted solely from
underestimation of the phosphorus loads from the City of
Marion and the Crab Orchard School; e.g., the phosphorus
load for Marion would have to be nearly three times greater
than the estimated load to lower the Crab Orchard Creek
export rate to that of Wolf Creek (16 kg/km2/yr). Therefore,
it appears that either there are other point sources in the
Crab Orchard Creek drainage or land-use practices result in
an unusually high phosphorus export. In either case, a heed
for further study of the drainage is indicated.

III. LAKE WATER QUALITY SUMMARY
Crab Orchard 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 three stations on the lake and usually 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 6.1 meters at station 1, 3.0 meters at sta-
tion 2, and 1.2 meters at station 3.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

C. Limiting Nutrient Study:
A 15% loss of inorganic nitrogen and a 150% gain in ortho-
phosphorus occurred in the assay sample between the time of
collection and the beginning of the assay, and the limiting
nutrient was shifted from phosphorus in the lake (the mean
inorganic nitrogen/orthophosphorus ratio was 17/1) to nitrogen
limitation in the assay sample (N/P = 6/1). Consequently, the
assay results are not representative of conditions in the lake
at the time the sample was taken (05/08/73).
As noted above, the lake data indicate phosphorus limitation
in May; however, nitrogen limitation is indicated in August (N/P
8/1) and October (N/P = 9/1).
-------
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*.
Except for Pin Oak Creek and Pigeon Creek, nutrient loads shown
are those measured minus point-source loads, 1f any. However, the
combined estimated nutrient loads for Carterville and Crainville
exceeded those measured in Pin Oak Creek, and the estimated Refuge
Headquarters loads exceeded the loads measured in Pigeon Creek.
Therefore, the background loads for these two streams were estimated
using the nutrient loads, in. kg/km2/yr, in Wolf Creek at station C-l
and multiplying by the Pin Oak Creek and Pigeon Creek drainage areas
in km2.
* See Working Paper No. 175.
-------
10
Nutrient loadings for unsampled "minor tributaries and Immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the nutrient loads,
in kg/km2/year, at station C-l and multiplying by the ZZ area in km2.
The City of Marion, the villages of Carterville and Crainville, and
the Crab Orchard School did not participate in the sampling program,
and nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/
year.
Estimates of nutrient contributions by wild ducks and geese
utilizing Crab Orchard National Wildlife Refuge were based on 50,000
over-wintering geese reported by the Fish and Wildlife Service
(Anonymous, 1969) and the following assumptions:
1. One-half as many ducks as geese over-winter.
2. Winter resident waterfowl are at the lake for
five months.
3. Each wild duck contributes 0.20 kg total phosphorus
and 0.45 kg total nitrogen per year (Paloumpis and
Starrett, 1960).
4. Each wild goose contributes the same amount of
phosphorus and nitrogen as one wild duck since
geese typically feed in fields away from the
lake several hours each day.

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 1s that which would
result in the receiving water remaining ollgotrophic 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.

Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Crab Orchard Lake:

"Permissible" (oligotrophic rate) 0.19
* Unusually high export rate probably is indicative of unmeasured point-source
influence.
