FOREWORD
The National Eutrophication Survey was initiated in 1972 as a
research project in response to an Administration comitment to
investigate the nationwide 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 [ 3O3(e)],
water quality criteria/standards review [ 3O3(c)], clean lakes [ 3l4(a,b)],
and water quality monitoring [ lO6 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, 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.
ACKNOWL EDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the New Hampshire Water Supply
and Pollution Control Division for professional involvement and

I. CONCLUSIONS
A. Trophic Condition:
Survey data and the records of others show that Glen Lake
is eutrophic. The lake exhibited oxygen depletion in the
hypolimnion, had moderately high mean nutrient concentrations,
and had only fair Secchi disc transparency during the Survey
sampling periods. Historically, the lake has supported nuisance
blooms of blue-green algae.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Glen Lake was phos-
phorus limited at the time the assay sample was collected. How-
ever, .the lake data show that at times Glen Lake may be only
narrowly phosphorus limited or even nitrogen limited.
C. Nutrient Controllability:
1. Point sources--During the sampling year, Glen Lake re-
ceived a total phosphorus load at a rate more than three times
that proposed by Vollenweider (in press) as “dangerous” (i.e.,
a eutrophic rate; see page 14). Of this load, it is calculated
that the conuilunity of Goffstown contributed about 50%.
It is noted in “Merrimack River Basin Water Quality Manage-
ment Plan” (Anonymous, 1973), that Phase I of the New Hampshire
State Plan calls for a regional waste treatment plant at Manchester
-------
2
with an interceptor from the plant to Goffstown which will elimi-•
nate the discharge to Glen Lake. It is calculated that when the
regional facilities become operational, the total phosphorus load
to the lake will be reduced to about 58 lbs/acre/yr (6.5 g/m 2 /yr).
The reduced rate will still be somewhat in excess of a eutro-
phic rate but should result in a persistent phosphorus limitation
in the lake and a significant reduction in the incidence and sever-
ity of nuisance algal blooms.
2. Non-point sources-—During the sampling year, the mean
phosphorus exports of the streams tributary to Glen Lake (see
page 14) compared favorably with Lake Winnipesaukee tributaries
(see Working Paper No. 11, “Report on Lake Winnipesaukee”) in
which the mean export was 65 lbs/mi 2 /yr and the range was from
27 to 148 lbs/mi 2 /yr.
The rather low phosphorus export of the Piscataquog River
(43 lbs/mi 2 /yr) indicates that if there are point sources in the
drainage, they are relatively minor ones. Note, however, that
the drainage area/lake area ratio of this river is 835/1, and
this accounts for the drainage contribution of over 47% of the
total phosphorus load reaching Glen Lake during the sampling
year.

II. INTRODUCTION
Glen Lake is a relatively small impoundment of the Piscataquog River
at Goffstown (see Map 1, page v). The watershed is primarily rolling hills,
and the vegatative cover is mainly mixed soft- and hardwood forests.
Shoal areas In the lake are reported as limited, and aquatic weeds are
said to be scant. However, algal blooms of nuisance proportions have
occurred, and copper sulfate has been used for control.
A variety of fish are present, but fishing is reported to be poor
(Anonymous, 1970).
Glen Lake is classified as a eutrophic water body (Anonymous, 1973),
and water quality is said to have changed little during the past decade.

IV. LAKE WATER QUALITY SUMMARY
Glen 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 2, page vi).
During each visit, a single depth-integrated (15 feet or near bottom to
surface) sample was composited from the stations for phytoplankton identi-
fication 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 55 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 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,

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that Glen Lake had a moderate level of
potential primary productivity at the time the sample was
collected. Also, the increased yields with increased levels
of orthophosphorus show that the lake was phosphorus limited
-------
9
at that time (note that the addition of only nitrogen re-
sulted in a yield not significantly different from the control
yield). However, the lake data indicate that Glen Lake at
times may be only narrowly phosphorus limited, as in the
epilimnion at station 1 in June, or even nitrogen limited,
as at station 2 in June where nitrogen to phosphorus ratios
were less than 10 to 1 (i.e., nitrogen limitation would be
expected).
It is likely that any appreciable reduction in phosphorus
loading to Glen Lake would result in a persistent phosphorus
limitation.
D. Trophic Condition:
Historically, periodic nuisance blooms of blue-green algae
have occurred in Glen Lake and have resulted In efforts to con-
trol the growths with copper sulfate. Reportedly, the most recent
treatment was in August, 1974 (MacDonald, 1974).
During the sampling year, the lake was characterized by
marked depression of dissolved oxygen in the hypolimnion, moder-
ately high nutrient levels, and only fair Secchi disc transparencies.
Survey limnologists reported an algal bloom in progress during the
August sampling visit.
While Glen Lake is clearly eutrophic, only the very short
hydraulic retention time is suppressing the effects 0 f very
high nutrient loading rates and preventing an extreme degree of
eutrophication.

V. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the New Hampshire National
Guard collected monthly near-surface grab samples from each of the tribu-
tary sites indicated on map 1 (page v), except for the high runoff months
of March and April, when two samples were collected at several stations,
and when ice cover or lack of flow prevented sampling. Sampling was begun
in August, 1972 and was completed in August, 1973.
Through an interagency agreement, stream flow estimates for the year
of sampling and a hmnormalizedu or average year were provided by the New
England District Office of the U.S. Geological Survey for the tributary
sites nearest the lake.
In this report, nutrient loads for sampled tributaries were calculated
using mean concentrations and mean annual flows. Nutrient loadings for
unsampled 1 minor tributaries and immediate drainage” (“ZZ” of U.S.G.S.)
were estimated by using the means of the nutrient loads, in lbs/mi 2 /year,
at stations B-i , C-i, D—l , E-l , and F-i and multiplying the means by the
ZZ area in m1 2 .
The operator of the Goffstown wastewater treatment plant provided
monthly effluent samples and corresponding flow data.

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”.
