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 freshwater lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concen-
trations, 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 nonpoint source pollution abatement in lake water-
sheds.
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
watershed 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 [ g314(a,b)], and water quality monitoring
[ lO6 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 condition
are being made to advance the rationale and data base for refine-
ment of nutrient water quality criteria for the Nation’s freshwater
lakes. Likewise, multivarlate 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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

I. CONCLUSIONS
A. Trophic Condition:
Lakes Hopatcong and Musconetcong are classified
as eutrophic on the basis of Survey data and field
observations. Hopatcong Lake is characterized by
moderate to low primary production as measured by
algal assay control yields, and low nutrient levels and
Secchi disc visibility. Oxygen depletion occurred
below 4.6 meters in the sumer and below 7.6 meters in
the fall. Chlorophyll a values ranged from a low of
5.5 pg/i in the fall to a high of 27.7 pg/l in the
spring. Survey limnologists reported bottom hydrogen
sulfide formation during fall sampling.
Musconetcong Lake is characterized by heavy growth
of submerged and emergent vegetation. Secchi disc
visibility and potential for primary production were
low. Chlorophyll a values ranged from a low of 3.7pg/l
in the fall to a high of 20.1 pg/i in the summer.
-------

In the past, partial annual chemical aquatic weed control
programs have been applied to Hopatcong and Musconetcong
Lakes. Ketelle and Uttorniark (1971) have recomended dredging
for both lakes for more permanent aquatic weed control and
partial diking of the existing Musconetcong Lake basin to
provide spoil areas.
B. Rate-Limiting Nutrient:
Assay results indicate that Musconetcong was limited
by available phosphorus levels at the time of sample collection.
Spikes with phosphorus, and nitrogen and phosphorus simul-
taneously resulted in increases in assay yield. The addition
of nitrogen alone did not stimulate a growth response. The
ratios of mean total inorganic nitrogen to mean orthophosphorus
(N/P) in sampled waters indicate phosphorus limitation during
spring and autumn.
Assay results for Hopatcong Lake are not considered
reliable because of a significant change in the nutrient
levels between the time the sample was collected and the
assay was begun. The N/P ratios in the lake data suggest
phosphorus limitation during spring and summer.
C. Nutrient Controllability:
1. Point Sources -
During the sampling year, the mean annual phosphorus
load from municipal point sources was estimated to be
26.7% of the total load reaching Hopatcong Lake. The
-------
3
Mt. Arlington Garden Apartments contributed 14.3% of this
load. There were no known industrial or municipal point
sources directly impacting Musconetcong Lake during the
sampling year.
It is known that municipal sewage from the Stanleck
School impacts Shawnee Lake directly above Hopatcong Lake.
However, annual nutrient export values (page 18) for Station
B(1) (Unnamed Stream) below Shawnee Dam do not reflect this
impact, probably due to the nutrient sink function of Shawnee
Lake. Thus, although loading from the Stanleck School may
eventually reach Hopatcong Lake, the main impact is to upstream
Shawnee. Therefore, estimated loadings for the school are not
included in this report.
The present loading of 0.12 g P/m 2 /yr (Hopatcong) is
below that proposed by Vollenweider (Vollenweider and Dillon,
1974) as °pernissibl&’ (oligotrophic) for a lake of such
volume and detention time. The loading value of 0.61 g P/m 2 /yr
(Musconetcong) is below Vollenweider’s “dangerous” (eutrophic)
level but above the “permissible” levels. Total elimination
of the known point sources impacting Hopatcong Lake would fur-
ther improve water quality in both lakes.
-------
4
2. Nonpoint Sources -
The mean annual phosphorus load from nonpolnt sources
was 73.3% of the total impacting Hopatcong Lake, and all
of the load directly reaching Musconetcong Lake. Septic
tanks were estimated to have contributed 24.8% of the load
to Hopatcong Lake. Ungaged tributaries contributed 26.0%
and 9.8% of the phosphorus load to each lake, respectively.

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized
below. The lake surface area and mean depth were provided
by the State of New Jersey. Tributary flow data were
provided by the New Jersey District Office of the U.S.
Geological Survey (USGS). Outlet drainage area includes the
lake surface area. Mean hydraulic retention time was
obtained by dividing the lake volume by the mean flow of
the outlet. Precipitation values were estimated by methods
as outlined in National Eutrophication Survey (NES) Working
Paper No. 175. A table of metric/English conversions Is
included as Appendix A.

III. LAKE WATER QUALITY SUMMARY
Hopatcong and Musconetcong Lakes were sampled three times
during the open-water season of 1973 by means of a pontoon-
equipped Huey helicopter. Each time, samples for physical
and chemical parameters were collected from five stations on
Hopatcong Lake and one station on Musconetcong Lake and from
a number of depths at each station (see maps, pages V and vi).
During each visit, depth-integrated samples were collected
from each station for chlorophyll a analysis and phytoplankton
identification and enumeration. During the first visit,
18.9-liter depth-integrated samples were cornposited for algal
assays. Maximum depths sampled were 2.1 meters at Station 1,
12.5 meters at Station 2, 13.4 meters at Station 3, 9.1 meters
at Station 4, and 4.0 meters at Station 5 on Hopatcong Lake;
and 0.9 meters at Station 1 on Musconetcong Lake. For a more
detailed explanation of NES methods, see NES Working Paper
No. 175.
The results obtained are presented in full in Appendix C
and are summarized in III A for waters at the surface and at
the maximum depth for each site. Results of the phytoplankton
counts and chlorophyll a determinations are included in III B.
Results of the limiting nutrient study are presented in III C.

2. Discussion —
The control yield of the assay alga, Selenastrum
capricornutum , indicates that the potential for primary
production In Musconetcong Lake was low at the time of
sampling. In the assay, the Increase In yield with
the addition of phosphorus as well as the lack of
increase when only nitrogen was added indicates phosphorus
limitation. Maximum growth potential was achieved with the
simultaneous addition of both phosphorus and nitrogen.
The N/P ratios in Lake Musconetcong were 12/1 and 15/1
in the spring and fall, respectively, indicating phosphorus
limitation, and 7/1 during summer sampling suggesting nitrogen
limitation at that time.
The algal assay results for Lake Hopatcong are not
considered reliable because of a significant change In the
nutrient levels between the time the sample was collected
and the assay was begun. However, N/P ratios In lake
chemistry data suggest phosphorus limitation in spring and
summer, with ratios of 22/1 and 16/1 , respectively, and
nitrogen limitation during the fall with a ratio of 10/1.

IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the New
Jersey National Guard collected monthly near-surface grab
samples from each of the tributary sites indicated on the
maps (pages v and vi), except for the high runoff month
of February when two samples were collected. Sampling was
begun in July 1973, and was completed in April 1974.
Through an Interagency agreement, stream flow estimates
for the year of sampling and a °normalized” or average year
were provided by the New Jersey District Office of USGS for
the tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries
were determined by using a modification of a USGS computer
program for calculating stream loadings. Nutrient loads
indicated for tributaries are those measured minus known
point source loads, if any.
Nutrient loadings for the unsampled “minor tributaries
and immediate drainage” (“ZZ” of USGS) in both lakes were
estimated by using the mean annual concentrations in
Unnamed Stream at Station B(l) ( Hopatcong Lake) and mean
annual ZZ flow.
-------
14
The operators of the Our Lady of the Lake School and
Mt. Arlington Garden Apartments (Mt. Arlington) wastewater
treatment plants provided monthly effluent samples and
corresponding flow data. Nutrient loads for the Consolidated
School were estimated at 0.567 kg P and 1.701 kg N/capital
180-day school year.

E. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Essentially, his “dangerous” loading is
one at which the receiving water would become eutrophic or
remain eutrophic; his “permissible” loading is that which
would result in the receiving water remaining oligotrophic
or becoming oligotrophic if morphometry permitted. A meso-
trophic loading would be considered one between “dangerous”
and “permissible”.
Note that Vollenweider’s model may not be applicable to
water bodies with short hydraulic retention times.
