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.
-------
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.

ROUND LAKE
STORET NO. 3630
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Round Lake is eutrophic. Of
the 26 New York lakes sampled in the fall of 1972, 24 had
less mean total phosphorus, 23 had less mean dissolved phos-
phorus, and 19 had less inorganic nitrogen. For all New York
data, 23 lakes had less mean chlorophyll a_, and 23 had greater
Secchi disc transparency.
B. Rate-Limiting Nutrient:
A significant loss of nutrients occurred in the assay sample
from the time of collection to the beginning of the assay, and
the results are not indicative of conditions in the lake. The
lake data indicate that the lake was phosphorus limited in the
fall (the N/P ratio was 16/1) but nitrogen limited at the other
sampling times (the N/P ratios were 7/1 or less).
C. Nutrient Controllability:
1. Point sources—During the sampling year, Round Lake
received a total phosphorus load at a rate more than five times
the rate proposed by Vollenweider (in press) as "dangerous";
i.e., a eutrophic rate (see page 12). It is estimated that the
Village of Round Lake contributed about 15% of that load. How-
ever/even complete removal of phosphorus at this source would
o
still leave a loading rate of 4.44 g/m /yr (in excess of four
-------
times the eutrophic rate), and it is concluded that point-source
phosphorus control would have little effect on the existing trophic
condition of Round Lake.
2. Non-point sources (see page 12)—The phosphorus exports
of Round Lake tributaries were quite high as compared to unim-
pacted New York streams elsewhere (e.g., the mean annual export
of 11 tributaries of nearby Sacandaga Reservoir* was 53 Ibs P/
2
mi ). The nutrient exports of the unnamed streams at stations
D-l and E-l were exceptionally high (particularly E-l) and it
is likely that those streams were impacted by point sources.
In all, it is estimated that non-point sources contributed
about 85% of the total phosphorus load to Round Lake during the
sampling year.

III. LAKE WATER QUALITY SUMMARY
Round 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 or more depths at one station on the lake (see map, page v).
During each visit, a single depth-integrated (near bottom to surface)
sample was collected for phytoplankton identification and enumeration;
and a similar sample was taken for chlorophyll a_ analysis. During the
last visit, a five-gallon depth-integrated sample was collected for
algal assays. The maximum depth sampled was 16 feet.
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 algal assay results are not considered indicative of
lake conditions because of nutrient losses in the sample during
shipping. However, the lake data indicate phosphorus limitation
in October (the N/P ratio was 16/1). At the other sampling times,
the data indicate nitrogen limitation (i.e., N/P ratios were 7/1
or less, and nitrogen 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 and May when two samples were collected. Samp-
ling 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*. However, the "outlet" of
Round Lake as sampled at station F-l (see map, page v) included 25.9
square miles of additional drainage, and the nutrient loads measured
were adjusted by subtracting the areal contributions of the excess
drainage area which were estimated in the same way as the ZZ area.
Nutrient loadings for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the nu-
2
trient loads, in Ibs/mi /year, at stations B-l, C-l, and D-l and
2
multiplying the means by the ZZ area in mi .
The Village of Round Lake did not participate in the Survey, and
nutrient loads 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".

* There was an apparent loss of nitrogen during the sampling year. This may
have been due to nitrogen fixation in the lake, solubilization of previously
sedimented nitrogen, recharge with nitrogen-rich ground water, unknown and
unsampled point sources discharging directly to the lake, or underestimation
of the nitrogen load from the Village of Round Lake. Whatever the cause, a
similar nitrogen loss has occurred at Shagawa Lake, Minnesota, which has been
intensively studied by EPA's National Eutrophication Research and Lake
Restoration Branch.
