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)j, 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.
-------
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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the New York Department of
Environmental Conservation for professional involvement and to
the New York National Guard for conducting the tributary sampling
phase of the Survey.
Henry L. Diamond, Commissioner of the New York Department of
Environmental Conservation, and Leo J. Hetling, Director, and
Italo G. Carcich, Senior Sanitary Engineer, Environmental Quality
Research, Department of Environmental Conservation, provided
invaluable lake documentation and counsel during the Survey.
Major General John C. Baker, the Adjutant General of New York,
and Project Officer Lieutenant Colonel Fred Peters, who directed
the volunteer efforts of the New York National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Keuka Lake is mesotrophic. Of the 26
New York lakes sampled in the fall of 1972, when essentially all
were well-mixed, only one had less mean total phosphorus, one
had less mean dissolved phosphorus, and 14 had less mean inor-
ganic nitrogen. For all New York data, seven had less mean
chlorophyll a_, and only three had greater Secchi disc transpar-
ency.
Survey limnologists noted that the water was very clear on
all sampling occasions, and no algal blooms were observed.
B. Rate-Limiting Nutrient:
The response of the test alga, Selenastrum capricornutum,
was atypical. However, the levels of nutrients observed in the
lake at the time of sampling indicate a very low level of pri-
mary productivity.
The lake data indicate phosphorus limitation at all sampling
times; i.e., N/P ratios were 51/1 or greater, and phosphorus
limitation would be expected.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Keuka Lake
received a total phosphorus load at a rate a little less than
-------
that proposed by Vollenweider (in press) as "permissible"; i.e.,
an oligotrophic rate (see page 11). Of that load, point sources
(septic tanks) are estimated to have contributed about 15%. It
does not appear likely that control of the phosphorus from these
sources would improve the trophic condition of Keuka Lake appreci-
ably.
2. Non-point sources(see page ll)--The phosphorus exports of
Keuka Lake tributaries were relatively low during the sampling
year and compare favorably to the exports of other unimpacted
streams studied elsewhere in New York (e.g., Canadaigua Lake*).
In all, the tributary phosphorus exports contributed about
33% of the total phosphorus load reaching Keuka Lake during the
sampling year.

III. LAKE WATER QUALITY SUMMARY
Keuka 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 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 (15 feet to surface) sample
was collected from the stations for phytoplankton identification 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 each of the stations for
chlorophyll a^ analysis. The maximum depths sampled were 74 feet at station
156 feet at station 2, and 100 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, refer to Appendix B.

C. Limiting Nutrient Study:
The response of the test alga, Selenastrum capricornutum,
was atypical, and the results are not reliable. However, the
levels of nutrients observed in the lake at the time of samp-
ling indicate a very low level of primary productivity (i.e.,
a dry weight of 0.4 mg/1 would be expected).
The lake data at the time of sampling as well as the other
occasions indicate phosphorus limitation; N/P ratios were 51/1
or greater, 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 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 tribu-
tary 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 unsam-
pled "minor tributaries and immediate drainage" ("ZZ" of U.S.G.S) were
2
estimated by using the means of the nutrient loads, in Ibs/mi /year, at
stations B-l, C-l, and G-l and multiplying the means by the ZZ area in
mi .
As far as is known, there are no waste treatment plants impacting
Keuka Lake. The Village of Hammondsport is assumed to be served by
septic tanks, and the loads attributed to that source were estimated*
and included with septic tank loads.

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".
