                          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
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 Utahs
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  Joes  Valley  Reservoir  is meso-
        trophic.   It ranked sixth in overall  trophic  quality when  the
        27 Utah lakes and reservoirs sampled  in 1975  were  compared using
        a combination of six parameters*.   Five of the  water bodies had
        less median total phosphorus,  one had less and  three had the
        same median dissolved orthophosphorus,  11  had less median  inor-
        ganic nitrogen, four had less  mean  chlorophyll  a^  and ten  had
        greater mean Secchi disc transparency.   Depression of dissolved
        oxygen with depth occurred at  sampling  station  1 in  September
        (3.8 mg/1  at 36.6 meters).
            Survey limnologists noted  some  surface concentrations  of
        algae in August.
    Bo   Rate-Limiting Nutrient:
            The algal assay results indicate  the reservoir was phosphorus
        limited in September.   The reservoir  data  indicate nitrogen limi-
        tation in May and phosphorus limitation in August  and September.
    C.   Nutrient Controllability:
            1.  Point sources—No known  point sources impacted Joes
        Valley Reservoir during the sampling  year.
            2.  Non-point sources—Non-point  sources  contributed the entire

phosphorus loading to the reservoir during the sampling year.
Lowry Creek contributed 45.9% of the total, Seely Creek con-
tributed 29.6%, and Littles Creek added 13.2%.   The ungaged
minor tributaries and immediate drainage contributed an esti-
mated 3.4%.
    The estimated phosphorus loading of 0.70 g/m2/year is less
than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading but is more than his suggested
oligotrophic loading (i.e., a mesotrophic loading; see page
11).  Therefore, management of the reservoir should be directed
toward prevention of any increase in the loading.

III.   WATER QUALITY SUMMARY
      Joes Valley Reservoir was sampled three times  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 reservoir (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  a_ analysis.  The maximum depths sam-
  pled were 36.9 meters at station 1  and 12.5 meters at station 2.
      The sampling results are presented in full  in  Appendix  D and are
  summarized in the following table.

            The  control  yield  of the assay alga,  Selenastrum capri-
        cornutum, indicates that the potential  primary  productivity
        of the reservoir was moderately low at  the time the sample
        was collected (09/24/75).  Also,  the increased  yield resulting
        from the addition of phosphorus alone indicates that the reser-
        voir was phosphorus limited at that time. Note that the addi-
        tion of  nitrogen alone did not result in  an  increased yield.
            The  reservoir data indicate nitrogen  limitation in May
        and phosphorus limitation in August and September (the mean
        inorganic nitrogen/orthophosphorus ratios were  4/1,  46/1,
        and 45/1, respectively).

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 (page v), except
 for the high runoff month of May when two samples  were collected at
 three of the sites.  Sampling was begun in November,  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 Utah 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 for unsampled "minor  tributaries  and immediate
 drainage" ("ZZ" of U.S.G.S.)  were estimated using  the mean  concen-
 trations in Littles Creek at station C-l  and the mean annual  ZZ
 flow.
     No known wastewater treatment plants  impacted  the reservoir
 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.

        Vollenweider phosphorus loadings
         (g/m2/yr) based on mean depth and mean
         hydraulic retention time of Joes Valley Reservoir:
            "Dangerous"  (eutrophic loading)                 0.84
            "Permissible"  (oligotrophic loading)            0.42
* There was an apparent loss of nitrogen during the sampling year.   This
  may have been due to nitrogen fixation in the reservoir,  solubllization of
  previously sedimented nitrogen, recharge with nitrogen-rich ground water,
  unsampled point sources discharging directly to the reservoir,  or insuffi-
  cient outlet sampling.  Whatever the cause, a similar nitrogen  loss has
  occurred at Shagawa Lake, Minnesota, which has been intensively studied
  by EPA's former National Eutrophication and Lake Restoration Branch (Malueg
  et al., 1975).
