                          FOREWORD
     The National Eutrophication Survey was initiated in 1972
in response to an Administration commitment to investigate the
nationwide 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,
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 nonpoint 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
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 [§303(e)], water quality criteria/standards review
[§303(c)], clean lakes [§314(a,b)]5 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 condi-
tion are being made to advance the rationale and data base for
refinement 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 EPA
and to augment plans implementation by the states.

I.    CONCLUSIONS
     A.    Trophic Condition:
               Moores Lake is considered eutrophic based upon
          field observations and analysis of Survey data.   The
          lake is characterized by extremely high chlorophyll a_
          levels and algal assay control yields.   Nutrient levels
          were high (0.245 mg/1 median  total phosphorus  and 2.400
          mg/1 median inorganic nitrogen) and Secchi  disc  visibility
          was low.   Phytoplankton genera identified were generally
          high pollution-tolerant forms.  Problem algal  blooms and
          unstable water levels have been reported (Ketelle, 1971;
          Lesser, 1966); the lake has a record of intensive chemical
          weed control  programs.
     B.    Rate-Limiting Nutrient:
               Algal assay results indicate that  Moores  Lake was
          limited by available phosphorus levels  at the  time of
          assay sample  collection.  Spikes with phosphorus, and
          nitrogen and  phosphorus simultaneously  result  in increases
          in assay yield.   Additions of nitrogen  alone did not
          stimulate a growth response.   Lake data concerning the
          ratios of avilable nitrogen to orthophosphorus in sampled
          waters substantiate these results.

-------
C.   Nutrient Controllability:
     1.   Point Sources - During the sampling year, the mean
          annual phosphorus load from point sources (the Camden-
          Wyoming wastewater treatment plant) was estimated to
          be 40.9% of the total load reaching Moores Lake.
          Although total elimination of this point source
          input would reduce loading to Moores Lake, reduction
          of nonpoint source loading as well as point source
          would be needed to substantially upgrade water
          quality.
     2.   Nonpoint Sources - The mean annual phosphorus load
          from nonpoint sources was 59.1% of the total  load
          reaching Moores Lake.  The Isaac Branch contributed
          54.9% of the total phosphorus load, and the ungaged
          drainage areas were estimated to have contributed
          4.0%.
               The present loading rate of 73.15 g P/m2/yr is
          approximately 23 times the "dangerous" (eutrophic)
          rate proposed by Vollenweider (in press) for a lake
          of such volume and detention time.  However,  Vollenweider's
          model may not apply to water bodies with short hydraulic
          retention times, and the mean hydraulic retention time
          for Moores Lake is only 2 days.  Determination of
          surrounding land uses and unknown nonpoint sources
          contributing loading is necessary before recommendations
          for lake improvement can be proposed.

II.   LAKE AND DRAINAGE BASIN CHARACTERISTICS
          Lake and drainage basin characteristics are itemized
     below.  Lake surface area was provided by the State of
     Delaware; mean depth was estimated based on Survey data;
     tributary flow data  were provided  by  the Delaware  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
          Moores 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 one or more depths at that station (see map, page v).
     During each visit, depth-integrated samples were collected
     from 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.   The maximum depth sampled was 0.9 meters.   For a
     more detailed explanation of NES methods, see NES Working
     Paper No.  175.
          The results obtained are presented in full in Appendix D
     and are summarized in III A for waters at the surface and at
     the maximum depth for the sampling 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 Moores Lake was very high at the  time of
          sampling.  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  simul-
          taneous addition of both  phosphorus and nitrogen.
               The ratios of the inorganic nitrogen to ortho-
          phosphorus for the spring, summer, and fall  samples
          were respectively 40:1, 27:1, and 14:1, further indi-
          cating phosphorus limitation.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
          For the determination of nutrient  loadings,  the  Delaware
     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  April  1973
     and was completed in March 1974.
          Through an interagency agreement,  stream  flow  estimates
     for the year of sampling and a "normalized" or average year
     were provided by the Delaware District  Office  of  the  USGS for
     the tributary sites nearest the lake.
          In this report, nutrient loads  for sampled tributaries
     were determined by using a modification of  the 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" ("II"  of USGS) were estimated by  using
     the mean annual  concentrations in Isaac Branch at Station
     A(2) and mean annual  II  flow.
          The operator of the Camden-Wyoming 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 (in press).
     Essentially, his "dangerous" rate is the rate at which the
     receiving waters 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."

                              Total Yearly
                         Phosphorus Loading Rate
                             (grams/m2/year)
     Estimated loading rate for Moores Lake                 73.15
     Vollenweider's "dangerous" or eutrophic rate            3.15
     Vollenweider1s "permissible" or oligotrophic rate       1.57
