                         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)]f clean lakes [§314(a,b)J,
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.

-------
                                 111
    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.

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Lake Shawnee 1s eutrophic.   It
        ranked fourteenth in overall trophic quality when the 20  Ohio
        lakes sampled in 1973 were compared using a combination of six
        lake parameters*.  Seven lakes had less median total  phosphorus,
        five had less median orthophosphorus, 17 had less median  inorganic
        nitrogen, 12 had less mean chlorophyll  ia, and nine had a  greater
        mean Secchi disc transparency.  Marked depression of dissolved
        oxygen with depth occurred at station 2 in August, and depletion
        occurred there in October.
            Survey limnologists did not observe algae concentrations or
        macrophytes, with the exception of an April algal bloom at station 2.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate that Lake Shawnee was phos-
        phorus limited at the time the sample was collected.   This finding
        is substantiated by the lake data; i.e., the mean N/P ratios were
        37/1 or greater on all sampling occasions.
    C.  Nutrient Controllability:
            1.  Point sources—During the sampling year,  the estimated
        phosphorus contribution from known point sources  was  only 1.1%
        of the total load to Lake Shawnee.  This input is attributed to
* See Appendix A.

-------
                                     2
        the unsewered homes around the lake.  The U.S.G.S. map used for
        determining the number of residences was dated 1968 and showed
        only fifteen dwellings.  However, the Survey limnologists reported
        the shoreline was almost completely developed with homes.  The
        additional homes probably would add significantly to the phosphorus
        input to Lake Shawnee.
            The present estimated loading of 0.60 g/m2/yr of total  phos-
        phorus is below that proposed by Vollenweider (Vollenweider and
        Dillon, 1974) as a eutrophic loading (see page 11).  However,  the
        lake is obviously eutrophic, and all phosphorus inputs to the  lake
        should be minimized to the greatest practicable extent to slow
        the rate of eutrophication.
            2.  Non-point sources—About 78% of the total annual phosphorus
        input to Lake Shawnee was contributed by Caesar Creek, and about
        17% is estimated to have been contributed by the immediate drainage
        and minor tributaries.
            The phosphorus export rate of Caesar Creek was a relatively
        low 15 kg/km2/yr (see page 10) and compares well with the export
        rates of two unimpacted tributaries of nearby Deer Creek Reservoir*
        (21 and 28 kg/km2/yr).

III.  LAKE WATER QUALITY SUMMARY
      Lake Shawnee 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 two  or more depths at each  station
  (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 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 a^ analysis.  The maximum depths
  sampled were 1.8 meters at station 1 and 7.6 meters at station  2.
      The lake sampling results are  presented in full in Appendix D and
  are summarized in the following table.

    2.  Discussion -
            The  control  yield  of the assay alga, Selenastrum  capri-
        cornutum, indicates  that the potential primary  productivity
        of Lake  Shawnee was  moderately  high at the time the sample
        was collected.   The  addition of phosphorus alone  produced a
        significant increase in yield over that of the  control.  Note
        that addition of nitrogen alone produced an  insignificant
        increase in yield, and phosphorus  limitation is indicated.
            The  lake data substantiate  phosphorus  limitation.  At all
        sampling times,  the  mean inorganic nitrogen/orthophosphorus
        ratios were 37/1  or  greater, and phosphorus  limitation would
        be expected.

-------
IV.  NUTRIENT LOADINGS
    {See Appendix E for data)
    For the determination of nutrient loadings, the Ohio 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 May, 1973, and was completed in April, 1974.
    Through an interegency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided  by  the
Ohio 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 loads, in kg/km2/year, at stations B-l and C-l of nearby
Rocky Fork Reservoir and multiplying the means by the ZZ area in km2.

    E.  Yearly Loadings:
            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 oligo-
        trophic if morphometry permitted.  A mesotrophic 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.

        Vollenweider phosphorus loadings
         (g/m2/yr) based on mean depth and mean
         hydraulic retention time of Lake Shawnee:
            "Dangerous"  (eutrophic loading)        0.68
            "Permissible"  (oligotrophic loading)   0.34
* There was an apparent loss of phosphorus from Lake Shawnee during  the
  sampling year.  This may have been due to unknown and unsampled point
  sources discharging directly to the lake or, more probably, to under-
  estimation of septic tank contributions.
