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 [ g303(e)l, water
quality criteria/standards review [ g303(c)], clean lakes [ 3l4(a,b)],
and water quality monitoring [ lO6 and 3O5(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.

TURNER RESERVOIR AND CENTRAL POND
STORET NO. 4403
I. CONCLUSIONS
A. Trophic Condition:
Both Turner Reservoir and Central Pond are eutrophic as
evidenced by high nutrient levels, high chlorophyll a values,
low Secchi disc transparencies, and depression of dissolved
oxygen with depth.
B. Rate Limiting Nutrient:
The algal assay results show that the Turner Reservoir-
Central Pond system was nitrogen limited at the time the assay
sample was collected. Reservoir and Pond sampling data confirm
this conclusion.
C. Nutrient Controllability:
1 . Point sources—-It is estimated that during the samp-
ling year the Turner Reservoir-Central Pond system received
a total phosphorus load at a rate about 45 times that proposed
by Vollenweider (in press) as dangerous; i.e., a eutrophic rate
(see page 17). It is calculated that municipal and industrial
point sources contributed nearly 94% of that load.
Preliminary plans and specifications for nutrient removal
at both the Attleboro and North Attleboro (Massachusetts) waste
treatment facilities have been approved by the Massachusetts
-------
2
Division of Water Pollution Control; and, at the time of
preparation of this report, the start of construction at
both places was awaiting funding. Also, the Attleboro
plan includes the interception and treatment of the wastes
from the Attleboro Dyeing and Finishing plant and the Dodge-
yule Finishing plant. The nutrient removal facilities to
be constructed are designed to provide mean effluent limits
of 0.5 mg/l of total phosphorus and 2.0 mg/l of soluble nitro-
gen. On the basis of Survey data, it is calculated that the
phosphorus limits will require about 93% P removal at the
Attleboro plant and about 85% P removal at the North Attleboro
plant. These levels of phosphorus removal , plus elimination
of the two industrial discharges, will reduce the total phos-
phorus loading to the Turner Reservoir-Central Pond system
by about 60% (from 693 lbs/acre/yr to 271 ibs/acre/yr).
The above reduction will result in a loading rate of 30.4
g P/m 2 /yr (still about 18 times Vollenweider’s “dangerous’ rate).
However, considering the lack of major aquatic nuisances with
the existing loading rates, the phosphorus reduction should
result in improvement in the trophic condition of the system.
2. Non-point sources--The non-point phosphorus export of
(presumably) unimpacted Coles Brook (see page 17) was over four
-------
2
times higher than the 50 Ibs/mi /yr of nearby unimpacted Quick
Stream (see Working Paper No. 27, "Report on Harris Pond") and
indicates unknown and unmeasured point sources may have been
contributing nutrients.

II. INTRODUCTION
The Turner River-Central Pond system originated with an impound-
ment of Tenrnile River at or just upstream from the present Massachusetts
State Highway 152 crossing. Some years later another dam was constructed
downstream at the existing outlet of Turner Reservoir. The two water
bodies are contiguous; but reportedly, they are not broadly joined (Ten-
nant and Chesebrough, 1974).
The system served as a raw water supply for the City of
until late 1970 when the City of Providence began providing
At present, there is little recreational use of the system;
City of East Providence is in the process of developing the
tion.
The shoreline is largely wooded and in its natural setting. Shoreline
development is restricted to a few scattered cottages on the east side.

IV. LAKE WATER QUALITY SUMMARY
Turner Reservoir and Central Pond were each 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 single station on each water body and from one or more depths (see map,
page v). During each visit, a single depth-integrated (near bottom to sur-
face) sample was composited from the stations for phytoplankton identifica-
tion and enumeration; and during the last visit, a single five-gallon depth-
integrated sample was composited from the two water bodies for algal assays.
Also each time, a depth-integrated sample was collected from each of the
stations for chlorophyll a analysis. The maximum depth sampled was 5 feet
in Turner Reservoir and 4 feet in Central Pond.
Although the two water bodies are contiguous, they are not broadly joined,
and there are significant differences in various parameters both in levels
and patterns (e.g., D.O., conductivity, and nutrients). Therefore, summaries
of data for the fall sampling period (when both water bodies were well-mixed)
are provided. The data are presented in full in Appendix B.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that the potential primary productivity
of the Turner Reservoir-Central Pond system was very high at
the time the combined assay sample was collected. Also, the
lack of significant change in yields with increased levels of
orhtophosphorus until nitrogen was also added shows that the
system was nitrogen limited when sampled. Note that the addi-
tion of only nitrogen resulted in a yield far greater than the
control yield.
Nitrogen limitation is also indicated by the data for each
of the water bodies at each sampling time; i.e., nitrogen to
phosphorus ratios were less than 2 to 1 on all occasions.

D. Trophic Condition:
Both Turner Reservoir and Central Pond are eutrophic as
evidenced by high nutrient levels, high chlorophyll a values, low
Secchi disc transparencies, and depression of oxygen with depth.
Also, the algal assay showed that the potential primary productivity
of the system was very high.
Despite extremely high nutrient loading rates, neither water
body is noted for the occurrence of nuisance aquatic growths,
although taste and odor problems caused by algae were common when
the system served as the raw water supply for the City of East
Providence, RI. Rooted aquatic vegetation is common in both water
bodies but reportedly does not constitute a problem except
in small isolated areas.

V. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the Rhode Island 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 July, 1973.
Through an interagency agreement, stream flow estimates for the year
of sampling and a unormalizedh or average year were provided by the New
England District Office of the U.S. Geological Survey for the tributary
sites nearest the lake.
Nutrient loads for Coles Brook were calculated using mean annual
concentrations and the mean annual flow. However, the sum of the esti-
mated point-source phosphorus loads exceeded the phosphorus load measured
in the Tenmile River at the inlet sampling station (A-l); and the Tenmile
River non-point phosphorus load was estimated using the Coles Brook load,
in lbs/m1 2 /yr, and multiplying by the Tenmile River drainage area in mi 2 .
Note, however, the nitrogen load is that measured at station A-l minus the
estimated point-source loads.
Nutrient loadings for unsampled “minor tributaries and immediate drain-
age” (“ZZ” of U.S.G.S.) were estimated by using the mean annual concentra-
tions in Coles Brook at station B-l and the mean annual ZZ flow.
-------
13
Discharges from the Attleboro and North Attleboro (Massachusetts)
wastewater treatment plants were sampled by the operators on a monthly
basis, and influent flow data were provided. With regard to flows,
personnel of the Massachusetts Division of Water Pollution Control
(Tennant and Chesebrough, 1974) advise that effluent flows of the Attle-
boro plant may be as little as one-third of the corresponding influent
flows because of evaporation from and seepage through the rather old
but sizable sand filters. Because of this, nutrient loads attributed
to Attleboro were estimated on the basis of information provided by
Tennant and Chesebrough (op. cit.).
Also, industrial wastes were not sampled during the Survey but
contribute significant amounts of nutrients in the drainage. In the
following loading tables, the nutrient loads given for industrial
sources are based on data also provided by Tennant and Chesebrough.

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 mor-
phometry permitted. A mesotrophic rate would be considered one
between “dangerous” and “permissible”.
