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.

I. CONCLUSIONS
A. Trophic Condition:
Aspinook Pond is a eutrophic impoundment characterized by
heavy growths of rooted aquatic vegetation, high turbidity, and
high nutrient levels.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Aspinook Pond was nitrogen
limited at the time the sample was collected. The pond data
indicate nitrogen limitation at the other sampling times as well.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Aspinook Pond
received a total phosphorus load at a rate more than 18 times the
rate proposed by Vollenweider (in press) as "dangerous"; i.e., a
eutrophic rate (see page 14). While Vollenweider's model may not
be applicable to water bodies with very short hydraulic retention
times, it is apparent that Aspinook Pond receives excessive nutrient
loads.
It is calculated that the three point sources considered in this
study contributed only 21% of the total phosphorus load. Even com-
plete removal of phosphorus at these sources would still leave a
phosphorus loading rate in excess of 14 times the eutrophic rate,
-------
and it is concluded that it will be necessary to institute
drainage-wide point-source phosphorus control to appreciably
improve the trophic condition of Aspinook Pond.
The interstate French River joins the Quinebaug River in
Thompson Township; industrial and municipal discharges to the
French River, including Massachusetts sources, appear to have
been significant contributors of nutrients to the system (Anon-
ymous, 1972A).
Also, it is evident that there were point sources contributing
phosphorus to the Quinebaug River above the confluence of the
French River and beyond the 25-mile limit of the Survey*. Note
that the mean total phosphorus concentration at station A-9--
about 22 stream miles above the inlet to the Pond--was 0.232 mg/1,
or nearly twice the mean concentration at inlet station A-2 (0.133
mg/1).
Cooperative interstate control of point-source phosphorus
inputs to the Quinebaug River-French River system should result
in some improvement in the trophic condition of Aspinook Pond.
However, to accomplish a significant improvement, it appears that
a high degree of phosphorus removal at the point sources will be
necessary because of the extensive drainage basin of the Pond,(see
below).
2. Non-point sources (see page 14)--During the sampling year,
the phosphorus export of the Quinebaug River was more than twice
* See Working Paper No. 1, "Survey Methods".
-------
that of Cone Brook and more than four times the export of Cory
Brook. This high export rate is indicative of the unmeasured
point sources outside the Survey limits.
The very high drainage area to pond area ratio of 1,430 to
1 necessitates the high degree of point-source control of phos-
phorus discussed above. Note that with no point-source impact,
2
non-point phosphorus contributions of only 22 Ibs/mi /yr (about
1/4 of the Cory Brook export) would result in a eutrophic loading
rate.
-------
II. INTRODUCTION
Aspinook Pond is an impoundment of the Quinebaug River extending
north-south through the townships of Lisbon, Griswold, and Canterbury.
Shoreline development is minimal, and the shores are largely wooded.
The Quinebaug River represents the only significant flow into the pond.
Several small brooks make minor contributions.
The water level of the pond fluctuates considerably as a result of
industrial draw-down. There is limited recreational use, largely fish-
ing, and the pond has been stocked with yellow perch, bullheads, golden
shiners, and bluegill sunfish (Anonymous, 1959). Full realization of
the recreational potential of the pond has been hampered by limited
access and heavy algal blooms.
Mud, sand, and gravel bottom constituents are largely covered by
a muck layer comprising much of the recent sediments. Contributions
to the muck layer come from the abundant submerged and emergent vege-
tation as well as the algal crops produced within the pond.

IV. LAKE WATER QUALITY SUMMARY
Aspinook Pond was sampled four 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 one
or more depths at one station on the pond (a second station was sampled
once in August; 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 chloro-
phyll ^analysis. During the last visit a five-gallon depth-integrated
sample was collected for algal assays. The maximum depths sampled were
12 feet at station 1 and 14 feet at station 2.
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 potential primary productivity
of Aspinook Pond was high at the time the sample was taken.
Also, the lack of yield response to successive increments of
orthophosphorus, until nitrogen was also added, shows the Pond
was nitrogen limited (note the marked increase in yield when
only nitrogen was added).

V. NUTRIENT LOADINGS
(See Appendix C for all data)
For the determination of nutrient loadings, the Connecticut 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 August, 1972, and was completed in October, 1973.
Through an interagency agreement, stream flows estimates for the year
of sampling and a "normalized" or average year were provided by the Con-
necticut 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.G.S. computer program for calculating
stream loadings*. Nutrient loads for "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated by using the means of the
2
nutrient loads, in Ibs/mi /year, in Cory Brook at station B-l and multi-
2
plying the means by the ZZ area in mi .
The discharges of the Danielson, Plainfield Village, Plainfield North,
and Putnam wastewater treatment plants were sampled by the operators on a
monthly basis, and flow data were provided. The loadings shown for the
Quinebaug River are those measured at station A-2 minus the point-source
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 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".
Note that Vollenweider's model may not be applicable to
water bodies with very short detention times.
