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)L clean lakes [§314(a,bj],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
m
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Woods Pond is a hypereutrophic
impoundment which receives heavy loads of phosphorus from muni-
cipal and industrial sources. Heavy algal blooms and broad
surface coverage by duckweed are recurrent phenomena. High algal
assay control yields substantiate the high primary productivity
reported. Turbidity was high and dissolved oxygen was depressed
when sampled.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Woods Pond was nitrogen
limited at the time the sample was collected. The ratio of inor-
ganic nitrogen to dissolved phosphorus (approximately 3 to 1 on
each sampling date) indicates that nitrogen limitation is a
sustained rather than a transient condition in the pond.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Woods Pond
received a total phosphorus load at a rate more than 60 times
that proposed by Vollenweider (in press) as "dangerous"; i.e.,
a eutrophic rate (see page 12). Now, Vollenweider's model
probably does not apply to water bodies with short detention
-------
times, and the mean hydraulic retention time of Woods Pond is
a very short 19 hours. Nonetheless, the existing trophic condi-
tion of the pond is evidence of excessive nutrient loads.
It is estimated that the point sources considered in this
study collectively contributed over 93% of the total phosphorus
load. While even complete removal of phosphorus at these sources
would still leave a loading rate nearly four times the eutrophic
rate, considering the very short hydraulic retention time of Woods
Pond and the probability that Vollenweider's model is not applicable,
it is likely that a high degree of phosphorus removal at the point
sources would result in a decrease in the incidence and severity
of nuisance algal blooms as well as reduce the phosphorus loading
to downstream Housatonic River impoundments.
2. Non-point sources—The estimated non-point phosphorus
2
export rate of the Housatonic River of 107 Ibs/mi /yr is comparable
to the export rates of Massachusetts streams studied elsewhere; e.g.,
Hager Pond and Rochdale Pond tributaries.
In all, it is estimated that non-point sources, including pre-
cipitation, contributed a little over 7% of the total phosphorus
load to Woods Pond during the sampling year.

III. LAKE WATER QUALITY SUMMARY
Woods Pond 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 a number of depths
at the single station on the pond (see map, page v). During each visit, a
depth-integrated (near bottom to surface) sample was collected for phyto-
plankton identification and enumeration, and a similar sample was collected
for chlorophyll ^analysis. During the last visit, a single five-gallon
depth-integrated sample was collected for algal assays. The maximum depth
sampled was four feet.
The results obtained are presented in full in Appendix B, and the data
for the fall sampling period, when the pond 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,

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the primary productivity in Woods
Pond was very high at the time the assay sample was col-
lected. The lack of significant increases in yield with
increasing levels of phosphorus spikes, until nitrogen was
also added, indicates that nitrogen was the limiting nutrient.
Note that there was a significant increase in yield (compared
to the control yield) when only nitrogen was added.
The pond data indicate nitrogen limitation at the other
sampling times as well (N/P ratios were less than 3/1, and
nitrogen limitation would be expected).
-------
IV. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the Massachusetts 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 March and April when two samples were collected. Sampling was begun in
September, 1972, and was completed in October, 1973.
Through an interagency agreement, stream flow estimates for the year
of sampling and a "normalized" or averaged year were provided by the
New England District Office of the U.S. Geological Survey for the tribu-
tary sites nearest the lake.
In this report, the nutrient loads of the outlet at station A-3 were
calculated using the mean concentrations and the mean annual flow. However,
the phosphorus loads calculated in this way for the Housatonic River inlet
at station A-2 were less than the sum of the upstream point-source loads,
so the background phosphorus load of the river was estimated using the mean
annual flow at station A-2 and the mean of the phosphorus concentrations
measured in 1974 in the East and West1 branches of the Housatonic River
(0.030 mg/1) by the Massachusetts Division of Water Pollution Control
(Anonymous, 1974).
The nitrogen load for unsampled "minor tributaries and immediate drain-
age" ("ZZ" of U.S.G.S.) was estimated by using the adjusted (minus point
-------
2
source) Housatonic River load, at station A-2, in Ibs/mi /year, and
2
multiplying by the ZZ area in mi . The ZZ phosphorus load was calcu-
lated using the mean phosphorus concentrations as at station A-2 and
the mean annual ZZ flow.
The operator of the Pittsfield wastewater treatment plant provided
monthly effluent samples and corresponding flow data. However, the
North Lennox wastewater treatment plant and the General Electric Company
discharges were not sampled, and the nutrient loads attributed to these
sources were provided by the Massachusetts Division of Water Pollution
Control (Chesebrough, 1975; Cooperman, et al., 1971).
It is assumed that the entire point-source nutrient loads reached
Woods Pond 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 waters 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".
Note that Vollenweider's model may not be applicable to
water bodies with very short hydraulic retention times.

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