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 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 [§303(e)], water
quality criteria/standards review [§303(c}], clean lakes [§314(a,b)]>
and water quality monitoring [§106 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 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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Pennsylvania Department of
Environmental Resources for professional involvement and to the
Pennsylvania National Guard for conducting the tributary sampling
phase of the Survey.
Walter A. Lyon, Director of the Bureau of Water Quality
Management, Richard M. Boardman, Chief of the Division of Water-
Quality, and James T. Ulanoski, Aquatic Biologist of the Division
of Water Quality, provided invaluable lake documentation and
counsel during the Survey, reviewed the preliminary reports, and
provided critiques most useful in the preparation of this Working
Paper series.
Major General Harry J. Mier, Jr., the Adjutant General of
Pennsylvania, and Project Officer Major Ronald E. Wickard, who
directed the volunteer efforts of the Pennsylvania National
Guardsmen, are also gratefully acknowledged for their assistance
to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Pocono Lake is mesotrophic. It
ranked fifth in overall trophic quality when the 17 Pennsylvania
lakes sampled in 1973 were compared using a combination of six
parameters**. Ten of the lakes had less median total phosphorus,
nine had less and one had the same median dissolved phosphorus,
none had less but one had the same median inorganic nitrogen, one
had less mean chlorophyll a_, and eight had greater mean Secchi
disc transparency. Marked depression of dissolved oxygen with
depth occurred at station 1 in July, 1973.
Survey limnologists noted higher aquatic plants along part
of the shoreline near station 2 in July.
B. Rate-Limiting Nutrient:
There was a loss of phosphorus and an apparent gain in
nitrogen in the assay sample between the time of collection
and the beginning of the assay and the results are not indica-
tive of conditions in the lake at the time the sample was taken.
The lake data indicate nitrogen limitation in April but
phosphorus limitation in July and October.
* Table of metric conversions—Appendix A.
** See Appendix B.
-------
C. Nutrient Controllability:
1. Point sources—The phosphorus contribution from known
point sources, including septic tanks, amounted to 37.9% of
the total phosphorus load to Pocono Lake during the sampling
year. The major portion of this load (37.4%) came from the
wastewater treatment plant at the Tobyhanna Army Depot.
Although the present loading rate of 0.93 g/m2/yr is below
the rate proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 12), phosphorus inputs from
all sources should be minimized to improve or maintain the
existing quality of Pocono Lake.
2. Non-point sources—The mean annual contribution from
non-point sources accounted for 62.1% of the total phosphorus
load to Pocono Lake. Tobyhanna Creek contributed 15.4%, Upper
Tunkhannock Creek contributed 22.4%, and Wagner Run contributed
6.7% of the total. Ungaged tributaries were estimated to have
contributed 15.6% of the load.
The phosphorus exports of the Pocono Lake tributaries were
quite low (see page 12} and compare well with the two tributaries
of nearby Stillwater Lake* (8 and 12 kg/km2/yr).

III. LAKE WATER QUALITY SUMMARY
Pocono 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 two
stations on the lake and from a number of depths at each station (see
map, page v). During each visit, a single depth-integrated {near
bottom to surface) sample was composited from the stations for phyto-
plankton identification and enumeration; and during the first visit,
a single 18.9-liter depth-integrated sample was composited for algal
assays. Also each time, a depth-integrated sample was collected from
each of the stations for chlorophyll ^analysis. The maximum depths
sampled were 4.0 meters at station 1 and 2.1 meters at station 2
(station 2 was not sampled in the fall due to lack of depth).
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

C. Limiting Nutrient Study:
There was a loss of phosphorus and an apparent gain in
nitrogen in the assay sample between the time of collection
and the beginning of the assay. As a result, the limiting
nutrient was shifted from nitrogen in the lake (N/P ratio =
12/1) to phosphorus limitation in the sample (N/P = >23/l),
and the assay results are not representative of conditions
in the lake at the time the sample was collected.
The lake data indicate nitrogen limitation in April
(N/P = 12/1) but phosphorus limitation in July (N/P = 27/1)
and October {N/P = 33/1).

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Pennsylvania
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 col-
lected. Sampling was begun in May, 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 Pennsylvania District Office of the U.S. Geological Survey for
the tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the
nutrient exports, in kg/km2/year, at station B-l and multiplying the
means by the ZZ area in km2.
The operator of the Tobyhanna Army Depot 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 (Vollen-
weider and Dillon, 1974). Essentially, his "dangerous" rate
is the rate at which the receiving water would become eutrophic
or remain eutrophic; his "permissible" rate is that which would
result in the receiving water remaining oligotrophic or becoming
oligotrophic if morphometry permitted. A mesotrophic rate 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.

(g/m2/yr) based on mean depth and mean
