FOREWORD
The National Eutrophication 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 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)L 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.
-------
iii
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.

STORE! NO. 3610
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Chautauqua Lake is eutrophic.
Of the 26 New York lakes on which sampling was completed, 18
had less mean total phosphorus, 16 had less mean dissolved
phosphorus, but none had less mean inorganic nitrogen. Nine-
teen of the lakes had less mean chlorophyll a, and 17 had
greater Secchi disc transparency.
B. Rate-Limiting Nutrient:
The results of the algal assay indicate that Chautauqua
Lake was limited by nitrogen at the time the assay sample was
collected. Nitrogen-to-phosphorus ratios in the lake confirm
the assay results.
C. Nutrient Controllability:
During the sampling year, there was an unexpected apparent
loss of both phosphorus and nitrogen from Chautauqua Lake; i.e.,
about 17% more phosphorus (5,680 pounds) and 12% more nitrogen
(84,230 pounds) were measured leaving the lake than can be
accounted for by all measured and estimated inputs (see pages
13 and 14).
The cause of the marked nutrient imbalance is not known,
but it is unlikely that a nutrient "wash-out" occurred or that
-------
a direct-discharge point source of that magnitude was over-
looked. Whatever the reason, the nutrient imbalance noted
above points to a need for a more detailed study before a
final assessment of the controllability of nutrients is made.
However, considering only the nutrient inputs, it is cal-
culated that about 53% of the total phosphorus loads and 11%
of the total nitrogen input to Chautauqua Lake originated from
the four wastewater treatment plants which discharge to the
lake.
Although a significant part of the phosphorus input to
the lake could be controlled by advanced waste treatment
or diversion of waste effluents, primary production in the
lake apparently is now limited by the availability of nitro-
gen. Theoretically, if phosphorus loadings were sufficiently
reduced, a phosphorus limited condition could be attained and
the eutrophication rate of the lake could be reduced.
According to sources outside the survey (Hetling, 1974),
Chautauqua Lake currently supports an excellent fishery, most
notably for muskellunge. At the same time, in certain areas
of the lake, excessive aquatic weed growths and phytoplankton
blooms interfere with the aesthetic and non-fishery recreational
values of the lake.
-------
In this case of apparent conflict between lake uses, the
more detailed studies referred to above should Include a
determination of the optimum level of nutrient input to satis-
fy the needs of the most important lake uses.

III. LAKE WATER QUALITY SUMMARY
Chautauqua Lake was sampled three times during the open-water season
of 1972 by means of a pontoon-equipped Huey helicopter. Each time, sam-
ples for physical and chemical parameters were collected from three sta-
tions 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 phytoplankton
identification and enumeration; and during the last visit, a single five-
gallon depth-integrated sample was composited for algal assays. Also
each time, a depth-integrated sample was collected from each of the sta-
tions for chlorophyll a^ analysis. The maximum depths sampled were 10
feet at station 1, 16 feet at station 2, and 15 feet at station 3.
The results obtained are presented in full in Appendix B, and the
data for the fall sampling period, when the lake was essentially 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,

productivity
of Chautauqua Lake was moderately high at the time the sam-
ple was collected. Also, the lack of significant change in
yields with increased levels of orthophosphorus, until nitro-
gen was also added, shows that the lake was nitrogen limited
-------

when sampled. Note that the addition of only nitrogen
resulted in a yield greater than the control yield.
Nitrogen limitation is also indicated by the lake
data at each sampling time; i.e., nitrogen to phosphorus
ratios were less than 9 to 1 on all occasions, and ni-
trogen 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 tribu-
tary sites indicated on the map (page v), except for the high runoff months
of April and May 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 determined
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 by
2
using the means of the nutrient loads, in Ibs/mi /year, at stations B-l,
C-l, D-l, E-l, F-l, H-l, J-l, and K-l and multiplying the means by the ZZ
.2
area in mi .
The operators of the Lakewood, Chautauqua Institute, and Mayville
v/astewater treatment plants provided monthly effluent samples and cor-
responding flow data. However, the Village of Celoron did not partici-
pate in the Survey, and nutrient loads there were estimated at 2.5 Ibs
p and 7.5 Ibs N/capita/year.
Working Paper No. 1.

The Little inlet was sampled at station A-l during the Survey year.
However, nutrient concentrations were so high (e.g., mean total P = 1.946
mg/1) that the suitability of the sampling site was questionable. There-
fore, the drainage area of the Little Inlet was included in the ZZ area,
and loads were estimated as discussed above. Note that at the concentra-
tions measured, the calculated non-point export load of this stream would
have been in excess of 6,000 pounds of phosphorus per square mile of drain-
age for the year as compared to the mean export of all of the other sampled
2
streams of about 81 Ibs/mi /yr (see page 15).

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 waters would become eutrophic or remain eutrophic;
his "permissible" rate is that which would result in the
receiving water remaining oligotrophic or becoming oligo-
trophic if morphometry permitted. A mesotrophic rate would
be considered one between "dangerous" and "permissible".
