                          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

 [§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.
ACKNOWLEDGMENTS

I.    CONCLUSIONS
     A.    Trophic Condition:
               Kill en Pond is considered eutrophic  based  upon  field
          observations and analysis of Survey  data.   Algal  blooms
          were present during summer and fall  sampling.   Phytoplankton
          genera identified were generally high  pollution-tolerant
          forms.  Chlorophyll a^ levels  were extremely high  and
          Secchi disc visibility was low.   Primary  productivity  as
          measured by algal  assay control  yield  was  high.   Unstable
          water levels and abundant emergent vegetation (spatterdock)
          have been  reported (Ketelle and  Uttormark,  1971;  Lesser,
          1966).
     B.    Rate-Limiting Nutrient:
               Algal  assay results indicate that Killen Pond was
          limited by available phosphorus  levels.  The ratios  of
          available  nitrogen to orthophosphorus  in  sampled  waters
          indicate phosphorus limitation during  spring and  summer
          sampling dates,  but nitrogen  limitation in the  fall.

-------
C.   Nutrient Controllability:
     1.   Point Sources - During the sampling year, the mean
          annual phosphorus load from point sources was esti-
          mated to be 52.2% of the total  load reaching Kill en
          Pond.  The Swift Co. poultry processing plant con-
          tributed 51.9% of the total load.  The present
          loading rate of 14.90 g P/m2/yr is about nine
          times that proposed by Vollenweider (in press) as
          "dangerous" (eutrophic) for a lake of such volume
          and detention time.  However, Vollenweider's model
          may not apply to water bodies with short hydraulic
          retention time and the mean hydraulic retention
          time for Kill en Pond is only 8 days.
     2.   Nonpoint Sources - The mean annual phosphorus load
          from nonpoint sources was 48.4% of the total load
          reaching Killen Pond.  The Murderkill River con-
          tributed 40.5% and the remaining tributaries were
          estimated to have contributed 7.0%.
          Recommendations have been made for the construction
     of a new water control structure on Kill en Pond (Ketelle
     and Uttormark, 1971; Lesser, 1966).   Stabilization of
     water levels in the lake would curtail the growth of
     spatterdock.  Additional information concerning current
     land uses is necessary before further recommendations
     for lake improvements can be made.

II.   LAKE AND DRAINAGE BASIN CHARACTERISTICS
          Lake and drainage basin characteristics  are  itemized
     below.   Lake surface area,  and mean  and  maximum depths
     were provided by the State  of Delaware;  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
          Kill en Pond 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 each 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, 18.9-liter depth-integrated
     samples were composited for algal assays.   Maximum depth  sampled
     was 1.2 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 D
     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 ^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 primary
        productivity in Killen Pond was extremely high at the
        time the sample was collected.  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 response was
        achieved with the simultaneous addition of nitrogen
        and phosphorus.
             The ratios of inorganic nitrogen to orthophosphorus
        in the field samples for spring and summer were 42:1 and
        37:1, respectively, indicating phosphorus limitation.
        The nitrogen to phosphorus ratio for the fall sampling
        data, however, was only 4:1, indicating nitrogen
        limitation at that time.

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" ("ZZ"  of USGS) were estimated by  using
     the mean annual concentrations in Unnamed Tributary at
     Station B(l) and mean annual ZZ flow.
          The operators of the  Felton (Lake Forest High School
     and Swift Co.) wastewater  treatmemt  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."
