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,
-------
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, multivarlate 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

BLACK LAKE
STORET NO. 3602
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Black Lake is eutrophic. Of
the 26 New York lakes surveyed in the fall of 1972, 12 had
less mean total phosphorus, 18 had less mean dissolved phos-
phorus, and one had less mean inorganic nitrogen. For all
New York data, 19 lakes had less mean chlorophyll a_, and 19
had greater Secchi disc transparency.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Black Lake was nitrogen
limited in October when the sample was collected. The lake
data indicate nitrogen limitation in July (N/P ratio was 4/1)
but phosphorus limitation in May (N/P ratio was 22/1).
C. Nutrient Controllability:
1. Point sources—There were no known point sources of
nutrients impacting Black Lake during the sampling year.
2. Non-point sources (see page 12)—The phosphorus exports
of the Black Lake tributaries were about four times higher than
the mean export of the tributaries to Carry Falls Reservoir*
further east in St. Lawrence County. Also, the rather low N/P
export ratios are indicative of unknown point sources.
* Working Paper No. 151.
-------
2
The present phosphorus loading rate of 1.6 g/m /yr 1s
well above that proposed by Vollenweider (in press) as "dan-
gerous"; i.e., a eutrophic rate (see page 12). Since there
are no known point sources, control of non-point sources of
phosphorus will be necessary to improve the existing trophic
condition of Black Lake.

III. LAKE WATER QUALITY SUMMARY
Black 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
(near bottom to surface) sample was composited from the two 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 stations for chlorophyll -a analysis. The maximum
depths sampled were 16 feet at station 1 and 9 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 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.

Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Black Lake was moderately high at the time the sample was
-------
8
collected. The response to the combined phosphorus and
nitrogen spike, as well as the positive response to nitro-
gen alone, indicate that Black Lake was nitrogen limited
at the time the sample was taken.
The lake data of the summer and fall sampling periods
show low N/P ratios ranging from 1/1 to 5/1 (nitrogen
limitation). The spring data show a N/P ratio of 22/1
(phosphorus limitation).
-------
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 month of April 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 un-
sampled "minor tributaries and immediate drainage" ("ZZ" of U.S.G.S.)
o
were estimated using the nutrient loads, in Ibs/mi /year, at station
2
B-l and multiplying by the ZZ area in mi .
There were no known point sources impacting Black Lake during the
sampling 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".
