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)J, 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.
-------
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.

lake documentation and counsel during the Survey, reviewed the
preliminary reports, and provided critiques most useful in the
preparation of this Working Paper series.

GREENWOOD LAKE, NEW JERSEY
STORET NO. 3403
I. CONCLUSIONS
A. Trophic Condition:
Based upon field observations and Survey data,
Greenwood Lake is considered early eutrophic. The
lake is characterized by summer depression of dis-
solved oxygen content, high total phosphorus levels
and abundant submerged and emerged aquatic vegetation.
Chlorophyll a values ranged from a low of 5.1 pg/i in
the fall to a high of 20.6 pg/i in the sumer. Mean
Secchi disc transparency was 217.8 cm.
In the past, herbicidal control has been practiced
annually or biannually. Ketelle and Uttormark (1971)
recommended partial dredging and removal of control-
lable nutrient sources for future control.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Greenwood Lake
was limited by available phosphorus. Spikes with
phosphorus or nitrogen and phosphorus simultaneously
resulted in increased assay yields. The addition of
nitrogen alone did not stimulate a growth response.
-------
2
The ratio of mean total inorganic nitrogen to mean
orthophosphorus (N/P) in lake waters during spring
sampling substantiates these results, but indicates
nitrogen limitation during summer and fall.
C. Nutrient Controllability:
1. Point Sources -
The mean annual phosphorus load from point
sources was estimated to be 13.4% of the load
reaching Greenwood Lake. The Birch Hill Park
Disposal Co. contributed 10.5% of the total load.
The nutrient loading to Greenwood Lake of
0.31 g/m 2 /yr was 1.4 times greater than the
“permissible” load proposed by Vollenweider (Vol-
lenweider and Dillon, 1974), and was about 1.5
times below his proposed “dangerous” load. Total
elimination of known point sources would result
in a drop of the loading rate and should gradually
improve the water quality of the lake.
2. Non-point Sources —
Non-point sources contribute 86.6% of the phos-
phorus loading reaching Greenwood Lake. Measured
tributaries contributed 40.7% of the total phosphorus
load and ungaged drainage areas were estimated to
contribute 20.9% of the load.

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
Greenwood Lake was 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 four stations on
the lake (Station 1 was sampled once, Stations 2 through
4 were sampled three times) and from one or more depths
at each station (see map, page v). 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 composited for algal assays.
Maximum depths sampled were 1 .5 meters at Station 1,
14.9 meters at Station 2, 8.5 meters at Station 3, and
1.5 meters at Station 4. 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
productivity in Greenwood Lake was moderately high at
the time of sampling. The lake was phosphorus limited
at that time as indicated by the increased growth of
the test alga in response to an addition of phosphorus.
Spikes with nitrogen and phosphorus simultaneously
resulted in a maximum yield while the addition of
nitrogen alone did not stimulate growth.
The N/P ratio of 20/1 in the spring lake data
further indicates phosphorus limitation. However,
N/P ratios in Greenwood Lake during summer and fall
were 10/1 and 8/1, respectively, suggesting nitrogen
limitation at those times.

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
map (page v), except for the high runoff months of February
and March when two samples were collected. Sampling was
begun in July 1973, and was completed In June 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 unsampled “minor tributaries and
immediate drainage” (“ZZ” of USGS) were estimated by using
the mean annual concentrations in Unnamed Creek at Station
C(l) and mean annual ZZ flows.
The operators of the Birch Hill Park and Marshall Hill
School wastewater treatment plants provided monthly effluent
samples. Nutrient loads for the plants were calculated using
the available monthly chemistry and flow estimates
(0.3785 m 3 /capita/day).

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.
