FOREWORD
The National Eutrophication Survey was initiated in 1972 as a
research project in response to an Administration commitment 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 [ g303(e)1, 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
to the New Hampshire National Guard for conduct of the tributary
sampl i ng phase of the Survey.
William A. Healy, Executive Director of the New Hampshire Water
Supply and Pollution Control Commission, Ronald E. Towne, Water
Pollution Biologist, and Kenneth MacDonald, Chief Water Pollution
Sanitarian, provided invaluable lake documentation and counsel during
the course of the Survey.
Major General Francis B. McSwiney, the Adjutant General of New
Hampshire, and Project Officer Lieutenant Colonel Russ Grady, who
directed the volunteer efforts of the New Hampshire National Guards-
men, are also gratefully acknowledged for their assistance to the
Survey.

KELLY’S FALLS POND
STORET NO. 3305
I. CONCLUSIONS
A. Tropic Condition:
Survey data and the records of others show that Kelly’s Falls
Pond is eutrophic. Mean chlorophyll a concentrations and low
Secchi disc transparencies are indicative of a eutrophic condi-
tion, but nutrient concentrations are indicative of a somewhat
better trophic condition. However, the very short hydraulic re-
tention time of the Pond is suppressing the effect of very high
nutrient loading rates.
B. Rate-Limiting Nutrient:
The results of the algal assay indicate the Pond was phosphorus
limited at the time the assay sample was collected. However, the
Pond data indicate that nitrogen was limiting at the other sampling
times.
C. Nutrient Controllability:
1. Point sources--During the sampling year, the Pond received
a total phosphorus load at a rate over six times greater than the
rate proposed by Vollenweider (in press) as “dangerous” (i.e., a
eutrophic rate; see page 14). It is calculated that Goffstown and
the Hilisboro County Home contributed about 21% of the total phos-
phorus load.
-------
2
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 Man-
chester with an interceptor from the plant to the Hilisboro
County Home and to Goffstown which will eliminate the point-
source loads to Kelly’s Falls Pond. However, when the regional
facilities become operational , the total phosphorus load to the
Pond will only be reduced to about 200 lbs/acre/yr or about 23
g/m 2 /yr (still about five times greater than a eutrophic rate)
because of non-point, and presumably uncontrollable, phosphorus
sources.
2. Non-point sources--During the sampling year, the total
phosphorus exports of the streams tributary to the Pond (see page
14) were appreciably higher (mean of 93 lbs/mi 2 /yr) than the ex-
ports of Glen Lake streams (mean of 68 lbs/mi 2 /yr). Note, however
that even if the phosphorus export of the Piscataquog River at
Kelly’s Falls Pond had been a very low 30 lbs/mi 2 /yr, the drain-
age area/pond area ratio of 1,060/1 would have ensured a non-point
source loading rate of more than 5 g/m 2 /yr (i.e., in excess of a
eutrophic rate).
-------
II. INTRODUCTION
Kelly's Falls Pond is located on the Piscatoquog River in north-
eastern Hillsborough County, New Hampshire. The Pond is approximately
2 miles in length and is situated almost immediately downstream from
Glen Lake. The dams impounding the two water bodies are only about
five stream miles apart, and the Glen Lake outlet sampling station
(3306A2) is only about 1.5 stream miles upstream from the Kelly's Falls
Pond inlet station (3305A1).

IV. LAKE WATER QUALITY SUMMARY
Kelly’s Falls 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 a single station on the Pond (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 collected for chlorophyll a analysis. During
the last visit, a single five-gallon depth-integrated sample was col-
lected for algal assays. The maximum depth sampled was 8 feet.
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, refer to Appendix B.

2. Discussion —
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that primary productivity of Kelly’s Fails
Pond was relatively low at the time the sample was collected.
However, there was loss of about 6 pg/i of dissolved phosphorus
from the time the sample was collected until the time the
assay was begun. Had this loss not occurred, the control
-------
9
yield probably would have been nearer 1 mg/i dry weight
(moderately productive).
The increased yields with increased levels of ortho-
phosphorus (to about 30 pg/l) show that the primary pro-
ductivity of the Pond was phosphorus limited at the time
the sample was collected (note that the addition of only
nitrogen produced no greater yield than the control).
However, the Pond data indicate that Kelly’s Falls Pond
was nitrogen limited in June and August (nitrogen/phosphorus
ratios were 10/1 and 7/1, respectively, and nitrogen limi-
tation would be expected).
0. Trophic Condition:
Data obtained during the Survey indicate that Kelly’s Falls
Pond is eutrophic. The Pond receives annual nutrient loadings
of 257 lbs/acre/yr (28.8 g/m 2 /yr) of phosphorus and over 2,600
lbs/acre/yr (292.7 g/m 2 /yr) of nitrogen. However, the “flow—
through” characteristic of the Pond (retention time of 1.5 days)
is minimizing nutrient retention and thus is suppressing the
effects of these excessive nutrient loadings.
-------
10
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 the map (page v), except for the high runoff months
of March and April, when two samples were collected, and the colder months
of the year when one or more samples were omitted, depending on the site.
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 normalized” 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 annual concentrations and mean annual flows. Nutrient loadings
for unsampled “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 /yr, at
stations B-i, C-i, and D-l and multiplying the means by the ZZ area in m1 2 .
Also, because of relatively insignificant flows and loads (P = <10 ibs;
N = 80 lbs), the nutrient loads measured at station [ -1 were added to the
loads calculated for the minor tributaries and imediate drainage.
-------
11
The Hilisboro County Home did not participate in the Survey, and
nutrients loads were estimated*. The Goffstown wastewater treatment
plant discharges to upstream Glen Lake , and the nutrient loads
attributed to that source were adjusted for the observed retention in
Glen Lake (32% of the phosphorus and 28% of the nitrogen). In the
loading tables, the nutrient loads attributed to the Piscataquog River
are those measured at station A-i 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 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”.

Volle weider loading rates for phosphorus
(g/m /yr) based on mean depth and mean
hydrualic retention time of Kelly’s Falls Pond:
“Dangerous” (eutrophic rate) 4.40
“Permissible” (oilgotrophic rate) 2.20
* 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, underestima-
tion of point—sources nitrogen loads, or a combination of these. Whatever
the cause, a similar nitrogen loss has occurred at Shagawa Lake, Minnesota,
which has been studied intensively by EPA’s National Eutrophication Research
and Lake Restoration Branch.
