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.
-------
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, II. S. Environmental Protection Agency)
expresses sincere appreciation to the New York Department of
Environmental Conservation for professional involvement and to

CASSADAGA LAKE
STORE! NO. 3607
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Cassadaga Lake is eutrophic. Of the
26 New York lakes surveyed in the fall of 1972, when essentially
all were well-mixed, 14 had less mean total phosphorus, 12 had
less mean dissolved phosphorus, and 17 had less mean inorganic
nitrogen. For all New York data, 10 lakes had greater Secchi
disc transparency, and 16 had less mean chlorophyll a^
B. Rate-Limiting Nutrient:
The results of the algal assay indicate that Cassada Lake
was phosphorus limited at the time the sample was collected.
The lake data also indicate phosphorus limitation; i.e., N/P
ratios were greater than 14/1 on all occasions, and phosphorus
limitation would be expected.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Cassadaga Lake
is estimated to have received a total phosphorus load at a rate
of 7.1 Ibs/acre/yr or 0.80 g/m2/yr. Of this load, it is esti-
mated that the Village of Lily Dale contributed nearly 67%.
Now the mean depth and, hence, the volume and mean hydraulic
retention time of the lake are not known; but, based on Vollen-
weider's model (in press), it is calculated that the loading rate
-------
2
would have to be reduced to 0.62 g/m /yr to equal a "dangerous"
or eutrophic rate (see page 12).
If the estimate of the phosphorus load from the Lily Dale
waste treatment facility is reasonable, it is calculated that
80% phosphorus removal at the Lily Dale waste treatment facility
2
would reduce the loading rate to 2.8 Ibs/acre/yr or 0.32 g/m /yr
(assuming the State-wide ban on phosphorus in detergents reduces
the phosphorus load to the facility by 50%).
The reduced loading would approximate Vollenweider's oligo-
trophic rate and should result in a significant improvement in
the trophic condition of Cassadaga Lake.
2. Non-point sources (see page 12)--The phosphorus exports
of the Cassadaga Lake tributaries were similar to the exports of
the tributaries to nearby Chautauqua Lake*. In all, it is esti-
mated that non-point sources contributed about 33% of the total
phosphorus load to the lake during the sampling year.

III. LAKE WATER QUALITY SUMMARY
Cassadaga Lake was sampled three times during the open-water season
of 1972 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from
one station on the lake and from a number of depths at that station
(see map, page v). During each visit, a single depth-integrated
(15 feet to surface) sample was collected for phytoplankton identifi-
cation and enumeration; and during the last visit, a single five-
gallon depth-integrated sample was collected for algal assays. Also
each time, a depth-integrated sample was collected from the station
for chlorophyll a_ analysis. The maximum depth sampled was 25 feet.
The results obtained are presented in full in Appendix B, and the
data for the fall sampling period, when the lake essentially was well-
mixed, are summarized below. Note, however, the Secchi disc summary
is based on all values.
For differences in the various parameters at the other sampling
times, refer to Appendix B.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
was high at the time the sample was collected. Also, the
increased yields with increased orthophosphorus, and the
lack of response when only nitrogen was added, indicates
that the lake was phosphorus limited when sampled.
The lake data indicate phosphorus limitation at the
other sampling times as well. The N/P ratios were 16/1 or
higher, and phosphorus limitation would be expected.

IV. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the New York 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 April, May, and June, when two samples were collected.
Sampling was begun in November, 1972, and was completed in October, .
1973.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the New York 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 loadings for
unsampled "minor tributaries and immediate drainage" ("ZZ" of U.S.G.S.)
were estimated using the means of the nutrient loads, in Ibs/mi2/year,
at stations B-l, C-l, and D-l and multiplying the means by the ZZ area
in mi2.
Nutrient loadings from the septic tank serving the Village of Lily
Dale were estimated at 2.5 Ibs P and 7.5 Ibs N/capita/year.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (in press).
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 consid-
ered one between "dangerous" and "permissible".
