                          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.

-------
                                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.'

ACKNOWLEDGEMENT

     The staff of the National Eutrophication Survey (Office of
Research and Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the Utah Department of Social
Services and the Utah Department of Natural Resources for pro-
fessional involvement, to the Utah National Guard for conducting
the tributary sampling phase of the Survey, and to those Utah
wastewater treatment plant operators who voluntarily provided
effluent samples and flow data.

     The staffs of the Bureau of Water Quality of the Division
of Health and the Division of Wildlife Resources provided inval-
uable lake documentation and counsel during the Survey, reviewed
the preliminary reports, and provided critiques most useful  in
the preparation of this Working Paper series.

     Major General Maurice L. Watts, the Adjutant General of Utah,
and Project Officer Lt. Colonel T. Ray Kingston, who directed, the
volunteer efforts of the Utah National  Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I.  CONCLUSIONS
    A.   Trophic Condition:
            Survey data indicate that Moon Lake is  oligotrophic.   It  ranked
        third in overall  trophic quality when the 27  Utah  lakes and reser-
        voirs sampled in  1975 were compared using a combination of six
        parameters*.   None  of the other  water bodies  had less median  total
        phosphorus or dissolved orthophosphorus,  none had  less but ten  had
        the same median inorganic nitrogen, six had less mean chlorophyll a_,
        and seven had greater mean Secchi disc transparency.  No  signifi-
        cant depression of  dissolved oxygen occurred  at depths as great as
        40.2 meters.
    B.   Rate-Limiting Nutrient:
            The algal assay results indicate the lake was  phosphorus  limited
        in September.  The  lake data indicate phosphorus limitation at  all
        sampling stations and times.
    C.   Nutrient Controllability:
            1.  Point sources—No known  point sources impacted Moon Lake
        during the sampling year.
            2.  Non-point sources--Non-point sources  contributed  the  entire
        phosphorus loading  to the lake during the sampling year.   The Lake
        Fork River contributed about 76% of the total  load,  and Brown Duck
        Creek contributed about 13%.
* See Appendix A.

                             2
    The estimated phosphorus loading of 0.52 g/m2/yr is  less
than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as an oligotrophic loading (see page 11).   Management of
the lake should be directed toward prevention of any increase
in the existing loading.

III.   WATER QUALITY SUMMARY
      Moon Lake was sampled twice during  the  open-water season  of
  1975 by means of a pontoon-equipped Huey  helicopter.   Each  time,
  samples for physical  and chemical  parameters were  collected from
  a number of depths at two stations on the lake  (see map,  page v).
  During each visit, a  single depth-integrated (4.6  m to surface) sample
  was composited from the stations for phytoplankton identification
  and enumeration; and  during the last 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  ^analysis.  The maximum  depths  sampled were  11.6
  meters at station 1 and 40.2 meters at  station  2.
      The sampling results are presented  in full  in  Appendix  D  and
  are summarized in the following table.

of Moon Lake was low at the time the sample was collected
(09/23/75).  Also, the significant increase in yield with
the addition of phosphorus alone indicates that the lake was
limited by phosphorus at that time.
    The lake data also indicate phosphorus limitation;  i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 23/1
or greater, and phosphorus limitation would be expected.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the Utah National
 Guard collected monthly near-surface grab samples when possible from
 each of the tributary sites indicated on the map (Pa9e v).   Sampling
 was begun in November, 1974, and was completed in October,  1975.
     Through an interagency agreement, stream flow estimates for the
 year of sampling and a "normalized" or average year were provided  by
 the Utah District Office of the U.S. Geological  Survey for  the
 tributary sites nearest the lake.
  .   In this report, nutrient loads for sampled tributaries  were
 calculated using mean annual concentrations and  mean annual flows.
 Nutrient loads for unsampled "minor tributaries  and immediate
 drainage" ("ZZ" of U.S.G.S.) were estimated using the mean  concen-
 trations in Fish Creek at station B-l and the mean annual ZZ flow.
     No known wastewater treatment plants impacted Moon Lake during
 the sampling year.

E.   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 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.

     hydraulic retention time of Moon Lake:

        "Permissible"  (oligotrophic loading)              0.58
