FOREWORD
The National Eutrophicatiori 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 oh 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
Elanninq [§303(e)], water quality criteria/standards review
§303{c}], clean lakes [§314(a,bj], and water quality monitoring
[§106 and §305{b)] activities mandated by the Federal Water
Pollution Control Act Amendments of 1972.
-------
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, 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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

STORE! NO. 3412
I. CONCLUSIONS
A. Trophic Condition:
Duhernal Lake is classified as eutrophic based upon
Survey data. The turbid, green lake is characterized by
low Secchi disc transparency, moderately high nutrient
levels and extensive growths of emerged and submerged
vegetation. Potential for primary productivity as
measured by algal assay control yield was low. Chloro-
phyll a_ values ranged from a low of 1.5 yg/1 in the
spring to a high of 10.3 pg/1 in the fall.
Past studies (Ketelle and Uttormark, 1971) recom-
mended complete dredging as possible weed control
treatment in Duhernal Lake.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Duhernal Lake
was limited by available phosphorus levels. Spikes
with phosphorus, and nitrogen and phosphorus simul-
taneously resulted in increases in assay yield. Additions
of nitrogen alone did not stimulate a growth response.
The mean total inorganic nitrogen to mean orthophosphorus
ratio (N/P) in sampled waters substantiates phosphorus
limitation.
-------
2
C. Nutrient Controllability:
1. Point Sources -
During the sampling year, the mean annual phosphorus
load from point sources was estimated to be 85.6% of the
total load reaching Duhernal Lake. The Pine Brook sewage
treatment plant contributed 42.5%, the Jamesburg plant
contributed 22.7%, and the Central Jersey Sewer Company
contributed 18.2%. The present loading of 60.18 g P/m2/yr
is about 19 times that proposed by Vollenweider (Vollen-
weider and Dillon, 1974) as "dangerous" (eutrophic). How-
ever, Vollenweider's model may not apply to lakes with such
short retention times.
While it is unlikely that practicable control of point
and nonpoint nutrient sources would of itself eliminate the
existing macrophyte problem in this shallow lake, other
parameters of water quality would be expected to improve.
2. Nonpoint Sources -
The mean annual phosphorus load from nonpoint sources
was 14.4% of the total load reaching Duhernal Lake. Measured
tributaries accounted for 14.0% of the total, and ungaged
tributaries accounted for 0.3%.

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized
below. Lake surface area, mean depth and maximum 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 mean flow
of the outlet. Precipitation values are 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
Duhernal 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 one station on
the lake and from one or more depths at that station
(see map, page v). During each visit, a depth-integrated
sample was collected at the station for chlorophyll a^
analysis and phytoplankton identification and enumeration.
During the first visit, an 18.9-liter depth^integrated
sample was composited for algal assays. Maximum depth
sampled was 1.5 meters at Station 1. 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 the site. Results of the phyto-
plankton 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 potential for primary
production in Duhernal Lake was low at the time of
sampling. Increased yield with the addition of phos-
phorus as well as the lack of increase when only nitro-
gen was added indicates phosphorus limitation. Maximum
growth potential was achieved with the simultaneous
addition of both phosphorus and nitrogen.
The N/P ratios were about 235/1 in the spring
field sample, 55/1 in the summer, and 153/1 in the
fall, further suggesting phosphorus limitation in
Duhernal Lake.
-------
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 vi), except for the high runoff month of February
when two samples were collected. Sampling was begun in
July 1973, and was completed in February 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 the USGS
for the tributary sites nearest the lake.
In this report, nutrient loads for Iresick Brook,
Station B(l), 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) and for Unnamed
Stream, Matchaponix Brook, and Manalapan Brook at Stations
C(l), D{1), and E(l), respectively, were estimated by using
the mean annual concentrations in Iresick Brook at Station B(l)
and the mean appropriate annual flow.

The operators of the Central Jersey Sewer Company, Pine Brook,
New Jersey Training School for Boys, and Helme Products (Helmetta)
wastewater treatment plants provided monthly effluent samples and
corresponding data. Nutrient loads for the city of Jamesburg waste-
water treatment plant were estimated at 1.134 kg P and 3.401 kg N/
capita/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.
