FOREWORD
The National Eutrophication Survey was initiated 1n 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)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.
-------
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.
ACKNOWLEDGMENT

I. CONCLUSIONS
A. Trophic Condition:
Survey data and the records of others (Ketelle and Uttormark,
1971) show that Conesus Lake is eutrophic. Of the 26 New York
lakes sampled in the fall of 1972, when essentially all were
well-mixed, 11 had less mean total phosphorus, 21 had less mean
dissolved phosphorus, and three had less mean inorganic nitrogen.
For all New York data, 15 had less mean chlorophyll a_ and 6 had
greater Secchi disc transparency.
Depression of dissolved oxygen with depth occurred at both samp-
ling stations in July, and Survey limnologists also noted an algal
bloom in progress at that time.
B. Rate-Limiting Nutrient:
A significant loss of nutrients occurred in the algal assay sample
between the time of collection and the beginning of the assay, and
the results are not indicative of lake conditions. However, the
lake data indicate that nitrogen was limiting during the May and
October samplings (N/P ratios were less than 8/1), and phosphorus
was limiting during the July sampling when the N/P ratio was 19/1.
C. Nutrient Controllability:
1. Point sources—During the sampling year, the mean annual
contribution from point sources was about 9% of the total phosphorus
-------
load, all of which originated from septic tanks along the lakeshore.
The Conesus Lake area is now served by a peripheral sewer system which
has eliminated discharges that once reached the lake, and the City
of Livonia has diverted its effluent out of the basin since the
summer of 1973 (Oglesby, 1974). Also, the only industrial source
of nutrients is now using land disposal of wastes.
The existing phosphorus loading rate of Conesus Lake is 3.2 Ibs/
2
acre/year or 0.36 g/m /year which is at a rate proposed by Vollen-
weider (in press) as a mesotrophic rate (see page 11). It is
expected that the control measures recently put into practice will
alleviate the eutrophic symptoms evident in Conesus Lake.
2. Non-point sources (see page 11 )--The phosphorus exports of
the Conesus Lake tributaries were quite high as compared to streams
studied elsewhere in New York (e.g., tributaries to Canadaigua Lake*).
Even so, the phosphorus export of Wilkins Creek was from two to nine
times higher than the other Conesus tributaries. The high export
rate and the low N/P export ratio indicate the impact of the City
of Livonia which discharged to Wilkins Creek during much of the
sampling year.
In all, it is estimated that non-point sources contributed
about 93% of the total phosphorus reaching Conesus Lake (ignoring
the contribution from Livonia during a part of the sampling year).

III. LAKE WATER QUALITY SUMMARY
Conesus 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 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 (15 feet
or 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 collected for algal
assays. Also each time, a depth-integrated sample was collected from
each of the stations for chlorophyll ^analysis. The maximum depths
sampled were 42 feet at station 1 and 46 feet at station 2.
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:
A significant loss of nutrients occurred in the algal assay
sample between the time of collection and the beginning of the
assay, and the results are not indicative of conditions in the
lake. However, the lake data indicate that nitrogen was limiting
during the May and October samplings (N/P ratios were less than
8/1), and phosphorus was limiting during the July sampling when
the N/P ratio was 19/1.

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 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 A-l, B-l, C-l, F-l, G-l, and H-l and multiplying the means by the
ZZ area in mi .

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".
