FOREWORD
The National Eutrophicatlon Survey was Initiated In 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophicatlon 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 eutrophicatlon 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.
-------
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.

HOLIDAY LAKE
STORET NO. 1754
I. CONCLUSIONS v
A. Trophic Condition:
Survey data indicate that Holiday Lake is eutrophic. It
ranked 19th in overall trophic quality when the 31 Illinois
lakes sampled in 1973 were compared using a combination of six
parameters*. Twenty of the lakes had less median total phos-
phorus, 15 had less median dissolved phosphorus, 23 had less
median inorganic nitrogen, 22 had less mean chlorophyll a_, and
22 had greater mean Secchi disc transparency.
Survey limnologists reported a blue-green algal bloom in
progress in August, 1973.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Holiday Lake was phos-
phorus limited at the time the sample was collected (05/09/73).
The lake data indicate phosphorus limitation in August as well
but nitrogen limitation in October.
C. Nutrient Controllability:
1. Point sources—The only known point sources impacting
Holiday Lake were the towns of Waterman, which contributed 23.3%
of the total phosphorus load, and Somonauk which contributed
* See Appendix A.
-------
25.1%. Information on nutrient loads from shoreline septic
tanks is lacking, but the Survey limnologists noted that the
shoreline is well developed, and the lake is assumed to be under
much seasonal recreational pressure. Nutrient loads from these
sources probably contributed to the poor water quality observed
at Holiday Lake.
The present phosphorus loading rate of 4.03 g/m2/yr is over
four times that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading rate (see page 12). Complete
removal of phosphorus at the two point sources above would reduce
the loading to 2.08 g P/m2/yr. This would still be above the
eutrophic loading rate but probably would result in persistent
phosphorus limitation and a reduction in the incidence and
severity of nuisance algal blooms in Holiday Lake.
2. Non-point sources—Somonauk Creek contributed nearly 45%
of the total phosphorus load reaching Holiday Lake during the
sampling year. The ungaged drainage areas were estimated to have
contributed 6.4% of the total.
The phosphorus export rate of Somonauk Creek was estimated
to be a rather low 15 kg P/km2 (see page 12).

III. LAKE WATER QUALITY SUMMARY
Holiday 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 (near
bottom to surface) sample was composited from the stations for phyto-
plankton 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 0.9 meters at station 1 and 4.0 meters at station 2.
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 Holiday Lake was high at the time the assay sample was
collected (05/09/73). There was a significant increase in
yield when the level of orthophosphorus was increased, but
there was no change in the yield compared to the control
when only nitrogen was added. Based on these results, phos-
phorus limitation is indicated.
The lake data indicate phosphorus limitation in August
also (the mean N/P ratio was 74/1) but nitrogen limitation
in October (the mean N/P ratio was 3/1).

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 month of February 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 adjusted nu-
trient loads, in kg/km2/year, at station A-2 and multiplying by the
ZZ area in km2.
The communities of Waterman and Somonauk did not participate in
the Survey, and nutrient loads were estimated at 1.134 kg P and 3.401
kg N/capita/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/m2/yr 4.03 1.40 201.5 25.8
Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Holiday Lake:
"Dangerous" (eutrophic rate) 0.98
"Permissible" (oligotrophic rate) 0.49
