                          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
freshwater 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.

ACKNOWLEDGMENT

    The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Wyoming Department of Environ-
mental Quality for professional involvement, to the Wyoming National
Guard for conducting the tributary sampling phase of the Survey,
and to those Wyoming wastewater treatment plant operators who
voluntarily provided effluent samples.

I.   CONCLUSIONS
    A.   Trophic Condition:
            Seminoe Reservoir ranked fourth in overall  trophic quality
        among the 14 Wyoming lakes and reservoirs sampled in 1975 when
        compared using a combination of six water quality parameters*.
        However, the reservoir data indicate that this  relatively
        long water body (ca.  38 km) is eutrophic at stations 1 and 2
        (the North Platte River and Medicine Bow River  embayments),
        moderately eutrophic at station 3, and mesotrophic at stations
        4 and 5 nearest the dam.
            At stations 1 and 2,  spring and fall mean tqtal  phosphorus
        ranged from 29 to 461  ug/1; mean dissolved orthophosphorus ranged
        from 4 to 32 ug/1;  mean inorganic nitrogen ranged from 90 to 340
        ug/1; mean chlorophyll  a_ ranged from 1.7 to 7,7 yg/1; and mean
        Secchi disc transparency ranged from 0.2 to 0.8 meters.  No
        depression of dissolved oxygen with depth occurred at any of the
        sampling times.  Survey limnologists noted that the water was very
        turbid.
            At station 3, spring and fall mean total  phosphorus ranged
        from 26 to 47 ug/1;  mean dissolved orthophosphorus ranged from
        7 to 12 yg/1; mean  inorganic nitrogen ranged  from 110 to 220
        ug/1; mean chlorophyll  £ ranged  from 1.5 to 1.9 ug/1; and
        mean Secchi  disc transparency ranged from 0.5 to 0.3 meters.

-------
                                 2
    No significant depression of dissolved oxygen with depth occurred
    at any of the sampling times.
        At stations 4 and 5, spring and fall  mean total  phosphorus
    ranged from 18 to 48 yg/1; mean dissolved orthophosphorus
    ranged from 5 to 11  yg/1; mean inorganic nitrogen ranged from
    100 to 270 yg/1; mean chlorophyll  a^ ranged from 0.8 to 1.6
    yg/1; and mean Secchi disc transparency ranged from 0.8 to 3.0
    meters.  No significant dissolved oxygen depression with depth
    occurred at any of the sampling times.
B.  Rate-Limiting Nutrient:
        The algal assay results indicate the reservoir was phosphorus
    limited at the times the samples were collected (05/16/75 and
    10/16/75).  The overall reservoir data indicate phosphorus limi-
    tation in May and October but nitrogen limitation in August
    (08/27/75).  However, because of high turbidity during much of
    the sampling year (particularly at stations 1, 2, and 3), pri-
    mary productivity in the reservoir may be light-limited at
    times rather than nutrient-limited as indicated by the low to
    moderate chlorophyll a^ levels and phytoplankton numbers
    (page 7).
C.  Nutrient Controllability:
        1.   Point sources—During the sampling year, point sources
    accounted for 3.0% of the total  phosphorus input to Seminoe
    Reservoir.  The wastewater treatment plant at Rawlins contributed

-------
                             3
most of the load, and the facility at Medicine Bow contributed
less than 0.1%
    The present phosphorus loading of 2.91 g/m2/yr is almost
three times that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading (see page 15).  It is
calculated that the present phosphorus loading would have to
be reduced by 66% to equal the eutrophic level.  It is apparent
that non-point nutrient control, as well as point-source control,
would have to be considered, particularly if land conservation
measures are initiated in the drainage basin which could reduce
suspended sediments and the resultant turbidity in the reservoir.
    2.  Non-point sources—Non-point sources contributed 97% of
the total phosphorus load during the sampling year.  The North
Platte River contributed 60.7%, Medicine Bow River contributed
23.0%, and four other gaged tributaries collectively contributed
2.5%.  The ungaged minor tributaries and immediate drainage con-
tributed an estimated 10.2%.
    Water use in the drainage basin primarily is for irrigation.
It has been reported that 17,402 hectares (43,000 acres) are irri-
gated with water from the Medicine Bow River, and 87,009 hectares
(215,000 acres) are irrigated with water from the North Platte River
(Anonymous, 1975).  Any significant reduction in the nutrient load to
the reservoir probably would involve control of nutrients in irriga-
tion return flows.  Further investigation is needed to determine the
controllability of such nutrients.

III.   WATER QUALITY SUMMARY
      Seminoe 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 five stations on the reservoir (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 and last visits,
  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 10.7 meters at station 1, 4.3 meters at station 2,  30.8
  meters at station 3, 37.5 meters at station 4, and 47.2 meters  at
  station 5.
      The sampling results are presented in full in Appendix D and are
  summarized in the following table.

2.  Discussion -
        The control  yields of the assay alga,  Selenastrum capri-
    cornutiim, indicate that the potential  primary productivity
    of Seminoe Reservoir was moderately high at stations  1,  2,
    and 3 in May and moderate at all  other stations  at that  time
    and in October as well.  Also, in all  assays, substantial
    increases in yields with the addition  of phosphorus alone
    indicate the reservoir was phosphorus  limited at those times.
    Note that the addition of nitrogen alone resulted in  yields
    not significantly greater than those of the controls.
        The differences in the control yields  at stations 1,
    2, and 3 (south end of the reservoir)  and stations 3  and
    4 (north end of the reservoir) in May  indicate the differences
    in availability of nutrients for primary production.   Note
    that orthophosphorus concentrations at stations  1, 2,  and 3
    at that time were three times greater  than those at stations
    4 and 5.
        The reservoir data indicate phosphorus limitation in May
    and October but nitrogen limitation in August; i.e.,  the mean
    inorganic nitrogen/orthophosphorus ratios  were 19/1 and  17/1
    in May and October, respectively, and  11/1 in August.  However,
    the mean N/P ratios at each sampling station and time indicate
    that stations 1  and 2 tended more towards  nitrogen limitation
    in May and August.  Following is  a tabulation of the  N/P ratios
    at each of the sampling stations  and times with  the indicated

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the  Wyoming  National
 Guard collected monthly near-surface grab samples  from each  of  the
 tributary sites indicated on the map (page vi),  except for the  high
 runoff months of May and June when two samples were  collected.
 Sampling was begun in October, 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 Wyoming District Office of the U.S. Geological Survey for the
 tributary sites nearest the reservoir.
     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 at stations B-l,  D-l and E-l,  in  kg/km2/year, and multiply-
 ing the means by the ZZ area in  km2.
     The operators of the Medicine Bow and Rawlins  wastewater treatment
 plants provided monthly effluent samples  and  corresponding flow data.

F.   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.
