                         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 [5303(e)]s water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [5106 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
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 Loramie  is eutrophic.  It
        ranked nineteenth in overall trophic  quality when the 20 Ohio
        lakes sampled in 1973 were compared using a combination of six
        parameters*.   Eighteen of the  lakes had  less median total phos-
        phorus, 12 had less  and one  had  the same median dissolved ortho-
        phosphorus, 12 had less median inorganic nitrogen, 18 had less
        mean chlorophyll £,  and all  of the other lakes had greater mean
        Secchi disc transparency.
            Survey limnologists did  not  observe  any surface concentrations
        of algae but noted that higher aquatic plants were abundant in
        many areas of the lake.
            Almost continuous dredging of the lake  is required to main-
        tain satisfactory depths  (Ketelle and Uttormark, 1971).
    B.   Rate-Limiting Nutrient:
            The algal assay results  indicate  Lake Loramie was phosphorus
        limited at the time  the sample was collected  (05/04/73).  The
        lake data indicate phosphorus  limitation in August as well but
        nitrogen limitation  in October.
* See Appendix A.

                                 2
C.  Nutrient Controllability:
        1.  Point sources—The phosphorus contribution of known
    point sources amounted to 36% of the total  load impacting Lake
    Loramie during the sampling year.  The Anna, Botkins, and
    Minster wastewater treatment plants contributed 6.7%, 9.0%,
    and 23.3% of the total phosphorus load to the lake, respec-
    tively.  It is estimated that septic tanks  near the lake con-
    tributed less than 1%.
        The present phosphorus loading of 4.22  g/m2/yr is five
    times that proposed by Vollenweider (Vollenweider and Dillon,
    1974) as a eutrophic loading (see page 13).   However, Vollen-
    weider's model probably does not apply to water bodies with
    short hydraulic retention times, and the mean hydraulic retention
    time of Lake Loramie is only 29 days.  In view of the question-
    able applicability of the model and because the lake is mostly
    phosphorus limited, all phosphorus inputs should be minimized
    to the greatest practicable extent to slow  the aging of Lake
    Loramie.
        2.  Non-point sources—Nearly 64% of the total annual  phos-
    phorus input to Lake Loramie was contributed by non-point
    sources.  Loramie Creek contributed 41.4%,  and the ungaged tribu-
    taries were estimated to have contributed 21.9% of the total load.
        The phosphorus export rate of Loramie Creek (49 kg/km2/yr)  is

-------
                                    3
       somewhat high as compared to the two tributaries of nearby Indian
       Lake*  (20 and 34 kg/km2/yr).  The higher rate may have resulted
       from underestimation of the Anna and Botkins point-source loads,
       or the electroplating firm at Anna may have contributed phos-
       phorus directly to Clay Creek and thence to Loramie Creek (see
       page 10).

III.   LAKE WATER QUALITY  SUMMARY
      Lake Loramie 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 one or more 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 a_ analysis.  The maximum depth
  sampled at station  1  was  1.2  meters; only near-surface samples were
  taken 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  cajjri-
        cornutum, indicates that the potential primary  productivity
        of Lake  Loramie was very high at  the  time the sample  was
        collected (05/04/73).   The results also  indicate  the  lake
        was phosphorus  limited.   Note that the addition of phos-
        phorus alone produced a significant increase in yield, but
        the addition of only  nitrogen produced a  yield  no greater
        than that of the control.
            The  lake data indicate phosphorus  limitation  in August
        as well  (the mean inorganic nitrogen/orthophosphorus  ratio
        was 86/1).   However,  nitrogen limitation  is  indicated in
        October  (the mean N/P ratio was 4/1).

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 month of March  when two  samples were  collected.  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 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
                                   /
 determined by using a  modification of  a U.S. Geological Survey com-
 puter 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 nutrient exports,
 in  kg/km2/year, at station D-l of nearby Indian Lake and multiplying
 by  the ZZ area  in  km2.
     The communities of Anna, Botkins,  and  Minster did not participate
 in  the sampling program, and nutrient  loads  were estimated at 1.134 kg
 P and 3.401  kg  N/capita/year.

    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
        oligotrophic 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.

         hydraulic retention time of Lake Loramie:
            "Dangerous"  (eutrophic loading)        0.84
            "Permissible"  (oligotrophic loading)    0.42
* There was an apparent loss of nutrients during the sampling year.   This
  may have been due to solubilization of previously sedimented nutrients
  during dredging (see page 1), recharge with nutrient-rich  ground water,
  unknown and unsampled point sources discharging directly to the lake, or
  underestimation of the nutrient loads from the Minster sewage treatment
  plant which discharges to an unsampled tributary.
