                               FOREWORD
     The National Eutrophtcatlon 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,  concen-
trations, and impact on selected freshwater Takes as a basis for
formulating comprehensive and coordinated national,  regional,  and
state management practices relating to point source  discharge
reduction and nonpoint source pollution abatement in lake water-
sheds.

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
watershed 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
 Elanninq [§303(e)}, water quality criteria/standards review
 §303(c)], clean lakes [§314(a,bj], and water quality monitoring
[§106 and §305(b)] activities mandated by the Federal Water
Pollution Control Act Amendments of 1972.

-------
                               m
     Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condition
are being made to advance the rationale and data base for refine-
ment 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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

ACKNOWLEDGMENTS

I.    CONCLUSIONS



     A.    Trophic  Condition:*



               Survey data  indicate that  Foss  Reservoir  is early eutro-



          phic.  Of the 16 Oklahoma lakes (including Lake Texoma) sam-



          pled in  1974, 14 had greater  median  total phosphorus values,



          12 had greater  median inorganic nitrogen  levels, and 15 had



          greater  median  orthophosphorus  values  than Foss Reservoir.



          Chlorophyll  a_ values in the lake ranged from 1.9 yg/1 to



          6.8 yg/1, with  a mean of 4.9  yg/1.   Potential  for  primary



          production as measured  by algal  assay  control  yield was low



          in both  spring  and autumm sampling.  Secchi disc readings



          ranged from 0.5 m  -  1.7 m,  suggesting  possible light limita--



          tion in  portions of  the reservoir.



               Survey limnologists did  not observe  any nutrient-related



          problem  conditions such as  algal  blooms or aquatic nacrophytes



          during the visits  to the lake.   However,  other studies (Ketelle



          and Uttormark,  1971; Oklahoma Department  of Pollution Control,



          1975)  report that  the reservoir is no  longer of use as a



          municipal or industrial  water supply due  to an excessive



          accumulation of dissolved solids.





     *See  Appendix  E.

-------
B.   Rate-Limiting Nutrient:



          Mean inorganic nitrogen to orthophosphorus (N/P) ratios for



     the reservoir data were 8/1 and <6/l in the spring and fall, respec-



     tively, indicating primary limitation by nitrogen, and 24/1 in



     June suggesting phosphorus limitation at that time.  Algal assay



     results indicated primary limitation by phosphorus during spring



     and fall sampling, and low potentials for primary production in



     Foss Reservoir at those times.



C.   Nutrient Controllability:



     1.   Point sources -



               The mean annual phosphorus load from point sources was



          estimated to be 3.8% of the total load reaching Foss Reservoir



          during the 1974 sampling year.  The city of Mammon contributed



          this entire load.



               During the sampling year, outflows from Foss Reservoir



          were minimal or absent, and the Foss Reservoir outlet  (Washita



          River, tributary A-l) was not sampled.  It would appear that



          the lake intermittently acts as a nutrient sink, and any future



          proposed nutrient contributions to the reservoir should be



          considered in this light.  However, additional sampling is



          needed to determine  the true retention time and nutrient budget



          of Foss Reservoir before any conclusions as to nutrient con-



          trollability can be  drawn.

-------
2.    Nonpoint sources -
          Nonpoint sources (including precipitation)  contributed
     96.2% of the total phosphorus load to Foss Reservoir.   The
     Washita River contributed 61.1% of the total,  Quartermaster
     Creek contributed 18.4%, and ungaged drainage areas were es-
     timated to have contributed 10.2%.
          The phosphorus export rates of the Washita  River  and
                                           2
     Quartermaster Creek were 2 and 4 kg/km /yr, respectively
     (see Section IV-D) .  The rates are quite comparable to the two
     gaged tributaries impacting nearby Altus Reservoir* (range
     of 2-3 kg/km2/yr).
*See Working Paper No. 581, "Report on Altus Reservoir".

II.   LAKE AND DRAINAGE BASIN CHARACTERISTICS
          Lake and drainage basin characteristics are itemized  below.
     Lake surface area and mean depth were provided by the Oklahoma
     Department of Pollution Control; maximum depth was provided  by
     the Oklahoma Water Resources Board.  Tributary flow data were pro-
     vided by the Oklahoma District Office of the U.S. Geological  Survey
     (USGS).  Outlet drainage area includes the Take surface area.  Mean
     hydraulic retention time was obtained by dividing the lake volume
     by mean flow of the outlet.  Precipitation values are estimated by
     methods as outlined in National Eutrophication Survey (NES)  Working
     Paper No. 175.  A table of metric/English conversions is included as
     Appendix A.

III.  LAKE WATER QUALITY SUMMARY
          Foss Reservoir was sampled three times during the open-water
     season of 1974 by means of a pontoon-equipped Huey helicopter.   Each
     time, samples for physical and chemical  parameters were collected
     from three stations on the lake (Station 03 was sampled only  twice)
     and from a number of depths at each station (see map,  page v).
     During each visit, depth-integrated samples were collected from each
     station for chlorophyll a^ analysis and phytoplankton identification
     and enumeration.  During the first and last visits, 18.9-liter
     depth-integrated samples were composited for algal assays. Maximum
     depths sampled were 15.2 meters at Station 01, 6.1 meters at  Station
     02, and 8.8 meters at Station 03.   For a more detailed explanation
     of NES methods, see NES Working Paper No. 175.
          The results obtained are presented in full in Appendix C and
     are summarized in III-A for waters at the surface and  at the  max-
     imum depth for each site.  Results of the phytoplankton counts  and
     chlorophyll ^determinations are included in III-B.  Results  of the
     limiting nutrient study are presented in III-C.

2.    Discussion -
          The control  yield of the assay alga,  Selenastrum capri-
     cornutum, indicates that the potential  primary productivity of  Foss
     Reservoir was low at both times samples were collected (03/29/74,
     10/24/74).  The increases in yield with the addition  of phosphorus
     alone or nitrogen and phosphorus simultaneously indicate phosphorus
     limitation.  However, the very low response to simultaneous nitrogen
     and phosphorus spikes in the spring assay  suggests  that some  other
     factor rapidly became growth limiting.   The response  noted in the
     corresponding fall assay run is a far more typical  one.   In both
     assays, the addition of nitrogen alone did not result in a yield
     significantly greater than that of the control.   However, there were
     substantial losses in nutrients in the samples during storage and/or
     preparation for assay.  The significance of the findings must there-
     fore be tempered accordingly.
          Mean N/P ratios in the lake data were 8/1 and  <6/l  in the
     spring and fall,  respectively, suggesting  primary limitation  by
     nitrogen at those times.   The mean N/P ratio of 24/1  in June
     suggests phosphorus limitation at that time (a mean N/P ratio of
     14/1  or greater generally reflects phosphorus limitation).

IV.   NUTRIENT LOADINGS
     (See Appendix D for data)
          For the determination of nutrient loadings,  the Oklahoma
     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 April  and May when  two samples were
     collected.  Sampling was begun in November 1974,  and was  completed
     in August 1975.
          Through an interagency agreement, stream flow estimates for
     the year of sampling and a "normalized" or average year were pro-
     vided by the Oklahoma District Office of the USGS for the tributary
     sites nearest the lake.
          In this report, nutrient loads  for sampled tributaries were
     determined by using a modification of a USGS computer program  for
     calculating stream loadings.  Nutrient loads indicated  for tribu-
     taries are those measured minus known point source loads, if any.
          Nutrient loadings for unsampled "minor tributaries and imme-
     diate drainage" ("II" of USGS) were  estimated by  using  the mean
                                    2
     annual nutrient loads, in kg/km /year, in Quartermaster Creek  at
                                                                2
     Station C-l, and multiplying the means by the II  area in  km .
          Nutrient loads for the city of  Hammon wastewater treatment
     plant were estimated at 1.134 kg P and 3.401 kg N/capita/year.

F.    Yearly Loadings:
          In the following table,  the existing phosphorus  annual
     loading is compared to the relationship proposed by Vollenweider
     (1975).  Essentially, his "eutrophic"  loading is that at which the
     receiving waters  would become eutrophic or remain eutrophic;  his
     "oligotrophic" 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
     "eutrophic" and "oligotrophic".
          Note that Vollenweider's model may not be applicable to  water
     bodies with very  short retention times or in which light penetration
     is severely restricted from high concentrations of suspended  solids
     in the surface waters.
