                               FOREWORD
     The National Eutrophicatlon 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 lakes 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
planning [§303(e)], water quality criteria/standards review
L§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.

-------
     Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and tronhic 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.

I.    CONCLUSIONS
     A.    Trophic Condition:*
               On the basis of field  observations  and  Survey  data,  Lake
          Hefner is considered eutrophic,  i.e.,  nutrient  rich and  highly
          productive.  Whether such nutrient  enrichment  is  to be consid-
          ered beneficial or deleterious  is determined by its actual  or
          potential impact  upon designated beneficial  water uses of each
          lake.
               Potential  for primary  production  as indicated  by algal
          assay control yield  was high  on  both sampling occasions.
          Chlorophyll a_ values in the lake ranged  from 0.9  yg/1 to 8.6
          yg/1 with a mean  of  5.7 yg/1.  Of the  16 Oklahoma lakes,
          (including Lake Texoma) sampled  in  1974, 7 had  higher median
          total  phosphorus  levels,  6  had  higher  median inorganic nitrogen
          values, and 3 had higher  median  orthophosphorus levels than
          Lake Hefner.
               Survey limnologists  did  not report  any  problem algal
          blooms or macrophyte growths  in  the lake.  However, low  Secchi
          disc readings (range of 0.8 to  1.2  m)  suggest that  light may
          be  limiting primary  production  in Lake Hefner.

     *See  Appendix E.

-------
B.   Rate-Limiting Nutrient:
          Algal assay data indicate phosphorus was the primary limiting
     nutrient in Lake Hefner during spring sampling and nitrogen was
     limiting during fall.  Mean inorganic nitrogen to orthophosphorus
     (N/P) ratios in the lake data were 8/1 or less on all  sampling
     occasions, indicating primary limitation by nitrogen.
C.   Nutrient Controllability:
     1.    Point sources -
               There were two municipal point sources (El  Reno and
          Yukon) known to impact Lake Hefner during the 1974 sampling
          year.  However, loadings from these plants are not defined  in
          the lake nutrient budget on pages 13 and 14.   Lake Hefner
          is a storage reservoir for Oklahoma City and water is pumped
          in from the North Canadian River (through Bluff Creek Canal)
          when its flow is sufficient for pumping.  Input from the sew-
          age treatment plants  is indirectly received to Lake Hefner  via
          this pumping, and estimations for actual annual  contributions
          to the lake from these sources are not available.   Plant load-
          ings are reflected, however, in the calculated loadings for
          Bluff Creek Canal (B-l).
               The estimated annual  phosphorus loading to Lake Hefner
                       2
          of 0.45 g P/m /yr is  greater than Vollenweider's  proposed
          "eutrophic" level (1975).   Although Vollenweider's model  may

-------
     not be applicable to lakes in which epilimnetic  light  penetra-
     tion is severely restricted by the presence of suspended
     solids, actual  annual  loading to the lake may be higher than
     calculated due to runoff from Oklahoma City or unmeasured sew-
     age treatment plant influences.   Thus, any future nutrient
     addition to the lake should be carefully evaluated as  to its
     potential  impact on the trophic state of the lake.
2.    Nonpoint sources -
          During the sampling year, nonpoint sources  (including
     precipitation)  contributed all of the calculated nutrient
     budget to  Lake Hefner.   The Bluff Creek Canal (pumping some
     impacted water from the North Canadian River) contributed
     93.7% of the total phosphorus load, and ungaged  drainage areas
     contributed an estimated 2.4%.

-------
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 provided

     by the Oklahoma District Office  of the U.S.  Geological  Survey (USGS).

     Outlet drainage area includes the lake 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

III.  LAKE WATER QUALITY SUMMARY



          Lake Hefner 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 02  and  03 were



     only sampled 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  ^analysis and



     phytoplankton identification and enumeration.  During  the  first



     and last visits, 18.9-liter depth-integrated samples were  compos-



     ited for algal assays.  Maximum depths sampled were  18.3 meters  at



     Station 01, 18.6 meters at Station 02, and 4.3 meters  at Station



     03.  For a more detailed explanation of NES methods, see NES Work-



     ing 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 maxi-



     mum depth for each site.  Results of the  phytoplankton counts and



     chlorophyll a^ 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 was



     high in Lake  Hefner during both spring  and fall  sampling.   It  is



     anticipated that  the control yield would  have been  substantially



     higher were it not for significant nutrient losses  occurring



     between the time  of sample collection and assay.  The nutrient



     loss changed  the  relative proportions of  inorganic  nitrogen to



     orthophosphorus resulting in assay results of questionable  utility,



     at best.



          In the spring sample, the addition of phosphorus alone pro-



     duced a significant increase in yield over that of  the  control,



     indicating phosphorus limitation.  The  addition of  nitrogen alone



     did not result in any increase in  yield over that of the  control.



     In the autumn assay, the addition  of nitrogen alone resulted  in



     a significant increase in yield, indicating nitrogen limitation at



     that time.  The maximum increases  in yield over that of the control



     were achieved with the simultaneous  addition of both nutrients.



          Mean N/P ratios in the lake data were 8/1  or less  on all



     sampling occasions, suggesting primary  limitation by nitrogen  (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  generally  two
     samples were collected.   Sampling was begun in November  1974, and
     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 tribu-
     tary 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
     immediate drainage" ("II"  of USGS) were estimated by  using  the
     mean annual concentrations in Unnamed Creek at Station C-l  and
     mean annual II flow.

      flake Hefner is a storage reservoir for Oklahoma City and water is
       pumped in from the North Canadian River when its flow is sufficient
       for pumping.  Thus, input from sewage treatment plants is indirectly
       received to Lake Hefner via this pumping.

E.    Yearly Loadings:
          In the following table,  the existing phosphorus  annual  load-
     ing 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 remain-
     ing 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 penetra-
     tion is severely  restricted from high concentrations  of suspended
     solids in the surface waters.

                          Phosphorus Loading

     Estimated  loading for Lake Hefner                           0.45
