                          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 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 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
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.

ACKNOWLEDGMENT

    The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Kansas State Department of
Health and Environment for professional 'involvement, to the Kansas
National Guard for conducting the tributary sampling phase of
the Survey, and to those Kansas v/astewater treatment plant opera-
tors who voluntarily provided effluent samples and flow data.

    The staff of the Kansas Division of Environmental Health pro-
vided invaluable lake documentation and counsel during the Survey,
reviewed the preliminary reports, and provided critiques most use-
ful in the preparation of this Working Paper series.

    Major General Edward R. Fry, the Adjutant General of Kansas,
and Project Officer Colonel Albin L. Lundquist, who directed the
volunteer efforts of the Kansas National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Elk City Reservoir is potentially
        eutrophic.  However, because of persistent turbidity and resulting
        light-limitation, primary productivity in the reservoir is low
        (King, 1977).
            This water body ranked fourth in overall trophic quality when
        the 15 Kansas reservoirs sampled in 1974 were compared using a
        combination of six water quality parameters*.  Two of the reser-
        voirs had less median total phosphorus, none of the others had
        less median dissolved orthophosphorus, seven had less median
        inorganic nitrogen, none had less mean chlorophyll a_, and 13 had
        greater mean Secchi disc transparency.  Depression of dissolved
        oxygen with depth occurred at both sampling stations in June.
            Survey limnologists did not observe algal concentrations or
        macrophytes but noted the reservoir was quite turbid during all
        sampling visits.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate that Elk City Reservoir was
        phosphorus-limited at the time the sample was taken (10/03/74).
        The reservoir data indicate phosphorus limitation in April as well.
* See Appendix A.

-------
    However, the low Secchi disc transparencies and relatively
    low numbers of phytoplankton (page 6)  indicate primary pro-
    ductivity in the reservoir is light-limited rather than
    nutrient-limited as noted above.
C.  Nutrient Controllability:
        1.  Point sources—Point sources contributed an estimated
    6.1% of the total phosphorus load to Elk City Reservoir during
    the sampling year.   The Howard wastewater treatment plant con-
    tributed 2.9%, the Moline facility added 1.8%, and the Elk City
    plant contributed 1.4%.
        The present phosphorus loading of  2.23 g/m 2/yr is  2.7 times
    that proposed by Vollenweider (Vollenweider and Dillon, 1974)
    as a eutrophic loading (see page  13).   However, even complete
    removal of phosphorus at the point-sources listed above would
    only reduce the loading to about  2.5 times the eutrophic loading.
    Because of this and light-limited primary productivity, it is
    not likely that point-source phosphorus control would  result in
    any appreciable improvement in the trophic condition of the
    reservoir.
        2.  Non-point sources—It is  estimated that non-point sources
    contributed nearly 94% of the total phosphorus load reaching the
    reservoir during the sampling year. The Elk River contributed
    52.5%; Duck Creek,  12.4%; and the ungaged minor tributaries and
    immediate drainage contributed an estimated 28.3% of the total
    load.

III.   WATER QUALITY SUMMARY
      Elk City Reservoir was sampled three times during  the  open-water
  season of 1974 by means of a pontoon-equipped Huey helicopter.   Samples
  for physical and chemical parameters were collected from one or  more
  depths at one station in April  and two stations in June and  October
  (see map, page v).  During each visit, a single depth-integrated (4.6 m
  or near bottom to surface) sample was composited from  the  stations for
  phytoplankton identification and enumeration; and during the October
  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  a_ analysis.   The maximum depths
  sampled were 12.8 meters at station 1 and 1.5 meters at station  2.
      The sampling results are presented in full  in Appendix D and are
  summarized in the following table (the June nutrient samples were not
  preserved properly and were not analyzed).

    2.   Discussion -
            The control  yield of the assay alga,  Selenastrum  capri-
        cornutum,  indicates  that the potential  primary productivity
        of Elk City Reservoir was high  at the  time the sample was
        taken (10/03/74).  Also,  the significant  increase  in  yield
        with the addition  of phosphorus alone  indicates that  the
        reservoir  was  phosphorus  limited at that  time.   Note  that
        the addition of  nitrogen  alone  resulted in a yield  not  sig-

                         8
nificantly greater than that of the control.
    The reservoir data indicate phosphorus limitation as
well.  The mean inorganic nitrogen to orthophosphorus
ratios were 19 to 1 or greater in April  and October,  and
phosphorus limitation would be expected.   However,  because
of persistent turbidity, primary productivity is light-
limited rather than nutrient-limited (Kring,  1977).

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient  loadings,  the  Kansas 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 May and June  when  two samples  were  collected.
 Sampling was begun in October,  1974, and was  completed  in September,
 1975.
     Through an interagency agreement,  stream  flow  estimates for the
 year of sampling and a "normalized" or average  year  were provided by
 the Kansas District Office of  the U.S.  Geological  Survey for the
 tributary sites nearest the reservoir.
     In this report,  nutrient loads  for sampled  tributaries were
 calculated using mean annual concentrations and mean annual flows.
 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 mean concen-
 trations in Salt Creek at station B-l  and  the mean annual ZZ flow.
     The  operators of the Elk City and  Moline wastewater treatment
 plants provided monthly effluent  samples,  but corresponding flow data
 were not available.   Nutrient  loads from those  sources and the waste-
 water plant at Howard,  which was  not sampled, were estimated at 1.134
 kg  P and 3.401  kg N/capita/year;  and flows were  estimated at 0.3785
 m3/capita/day.

F.   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  morphemetry  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.
