                         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.

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.
                              Total Phosphorus       Total Nitrogen

    grams/m2/yr              0.93     0.09          35.4      9.6

    Vollenweider loading rates for phosphorus
     (g/m2/yr)  based on mean depth  and mean
     hydraulic retention time  of  Pocono Lake:
        "Dangerous"  (eutrophic rate)       1.16
        "Permissible"  (oligotrophic rate)  0.58
