                         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
.	 i                r

    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.

-------
                                 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 Atwood Reservoir  1s eutrophic
        It ranked first in overall trophic quality when the  20 Ohio
        lakes sampled in 1973 were compared using a combination of
        six lake parameters*.  None of the lakes had less median  total
        phosphorus or median dissolved phosphorus, two  had less median
        inorganic nitrogen, six had less mean chlorophyll a_, and  one
        had greater mean Secchi disc transparency.  Marked depression
        of dissolved oxygen occurred with depth at station 1 in July-
            Survey limnologists noted high numbers of algae  at stations
        3 and 4 in April and moderate numbers at station 3 in October.
        Dense submerged vegetation was observed near the shorelines  at
        stations 2 and 3 in October.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate the reservoir was pho^horus
        limited at the time the sample was taken (04/20/73).  The reser-
        voir data also indicate phosphorus limitation at all sampling sta-
        tions and times.
    C.  Nutrient Controllability:
            1.  Point-sources--More than 24% of the total phosphons load
        reaching Atwood Reservoir during the sampling year was contributed
        by the Carroll ton wastewater treatment plant.   Septic tanks were
        estimated to have contributed 0.5% of the total phosphorus  load.
* See Appendix A.

-------
    In addition, two industrial point sources discharge to
the reservoir via Town Creek/Indian Fork (see page 10).   Although
no information is available on the nutrient contributions of
these sources, they are of probable significance as indicated  by
the high phosphorus export rate of Indian Fork (see discussion
of non-point sources below).
    The present loading of 1.67 g P/m2/yr is more than  2.5  times
that proposed by Vollenweider (Vollenweider and Dillon,  1974)  as
a eutrophic loading (see page 13).  A 100% reduction of the phos-
phorus from the listed point sources would reduce the loading  to
1.26 g/m2/yr.  Although this loading would still  exceed the eutro-
phic loading, the reduction should at least help slow the rate of
deterioration now occurring in the reservoir, particularly  if  a
significant portion of the phosphorus export of Indian  Creek also
can be controlled.
    2.  Non-point sources—The phosphorus load from non-point
sources was estimated to be 75.1% of the total reaching  the reser-
voir during the sampling year.  Indian Fork contributed  62.1%;
Pleasant Valley Run, 2.5%; and Willow Run, 1.7%.   Minor tributaries
and immediate drainage contributed an estimated 7.8% of the total.
    Indian Fork appeared to be impacted by sources other than  non-
point; i.e., the phosphorus export rate was a high 106  kg/km2/yr
(see page 13).  This rate is much greater than the rates of the
other tributaries; e.g., Pleasant Valley Run (12 kg/km2/yr)  and

-------
Willow Run (9 kg/km2/yr); and indicates that the industrial point
sources probably are significant contributors to the total phos-
phorus load to the reservoir.         ,

III.   LAKE WATER QUALITY SUMMARY
      Atwood Reservoir 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 four stations on the lake  and  from one or more depths at each
  station (see map, page v).  During  each visit, a  single depth-inte-
  grated (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 collected from each of the  stations for chlorophyll a_ analysis.
  The maximum depths sampled were 8.2 meters at station  1,  4.6 meters
  at  station 2, 1.8 meters  at station 3,  and near-surface only at sta-
  tion 4.
      The lake sampling results are presented in full in Appendix D and
  are summarized in the following table.

        of Atwood Reservoir was moderately high at the  time the
        sample was collected (04/20/73).   There was a significant
        increase in yield when orthophosphorus was added  but  a lack
        of yield response when nitrogen alone was added.   Based  on
        these results, phosphorus limitation is indicated.
            The reservoir data also indicate phosphorus limitation;
        i.e., the mean inorganic nitrogen/orthophosphorus ratios were
        18/1  or  greater at all sampling stations  and times.

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 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 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 and multiplying
 the means by the ZZ area in km2.
     The operator of the Carroll ton wastewater treatment plant provided
 monthly effluent samples and corresponding flow  data.

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 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.
