                               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,  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 1s documented.  The report is formatted to provide  state
environmental agencies with specific Information for basin
 flanninq [§303(e)], water quality criteria/standards review
 §303(cj], clean lakes [§314(a,b)L 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 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 Survey data and  field observations,
          Palisades Reservoir is  considered  mesotrophic.   Of the  13
          Idaho lakes sampled in  1975,  6  had higher median total  phos-
          phorus (0.024 mg/1) levels, 1 had  higher median  inorganic
          nitrogen values  (0.080  mg/1)  and 9 had higher median  ortho-
          phosphorus (0.007 mg/1) levels  than Palisades Reservoir.
          Chlorophyll a^ levels ranged from 0.8  yg/1 to 5.6 yg/1 with
          a mean of 2.1 yg/1.  Potential  for primary production as
          measured by algal assay control yields was generally  low.
               Survey limnologists did not observe any problem  con-
          ditions during their visits to  the lake. The Idaho Depart-
          ment of Water Resources, et al.  (1975) reports  the stretch
          of the Snake River above Heise  which  includes Palisades
          Reservoir is high quality water, and  in stable  condition.
     *See Appendix E

-------
B.   Rate-Limiting Nutrient:
          The algal assay results indicate that Palisades Reservoir was
     colimited during September sampling (09/18/75)  and phosphorus
     limited during October (10/20/75).   The reservoir data suggest
     nitrogen limitation at all three sampling times.
C.   Nutrient Controllability:
     1.   Point sources -
               The city of Jackson was the only known  point source
          impacting Palisades Reservoir during the sampling year.   It
          is estimated that Jackson contributed less than 0.1% of  the
          total phosphorus load to the lake.
                                                                     2
               The calculated annual  phosphorus loading of 6.25 g  P/m /yr
          is over three times that proposed by Vollenweider (1975)  as
          "eutrophic" for a lake with such volume and  retention time.
          If the present loading continues, increasingly undesirable
          responses to enrichment are likely to occur.
     2.   Nonpoint sources -
              , Nonpoint sources contributed almost all  of the known
          nutrient loading to Palisades  Reservoir during the sampling
          year.  The Snake River contributed 68.8% of  the total phos-
          phorus load, the Greys River contributed 14.9%, and Salt  River
          contributed 13.1%.   Ungaged drainage areas were estimated
          to have contributed 0.9% of the total.   It is not known  how
          much of the apparent  nonpoint  contributions  from the Snake

-------
River are in fact attributable to an underestimation of nutrient
loadings from the community of Jackson.
     The phosphorus export rates of Greys River were substan-
tially greater during the sampling year than the other tribu-
taries to Palisades Reservoir (Section IV-D).  This inflation
may be due to unidentified point sources rather than to nonpoint
source inputs, but more extensive sampling is needed to determine
the location and significance of these possible sources.

-------
II.   LAKE AND DRAINAGE BASIN CHARACTERISTICS
          Lake and drainage basin characteristics  are itemized below.
     Lake surface area, mean depth and volume were provided by Martin
     and Hanson (1966).  Tributary flow data were  provided by the Idaho
     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 NES Working Paper No.  175.  A  table of metric/English
     conversions is included as Appendix A.

III.  LAKE WATER QUALITY SUMMARY
          Palisades  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 five stations on  the lake 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 September
     and October sampling,  18.9-liter  depth-integrated samples were
     composited for  algal assays.   Maximum depths sampled were 16.8 meters
     at Station 01,  8.5 meters at  Station  02, 45.1  meters at  Station  03,
     and 53.3 meters at Stations 04 and  05.   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 maximum
     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  yields of the assay alga,  Selenastrum capri-
     cornutum, indicate that the potential  for primary  production in
     Palisades Reservoir was low during September for sampling
     Stations 04, 05,  and during October for Stations 01-03, but high  in
     September for Stations 01-03.   In the October and  September
     (Stations 04, 05) assays,  the  addition of orthophosphorus  alone
     produced 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 those samples.  In the  September (Stations 01-03) assay, a
     growth increase accompanied the addition of either phosphorus  or
     nitrogen alone, suggesting colimitation by the two nutrients.
          The mean inorganic nitrogen to orthophosphorus ratios (N/P)
     in the lake data  were less than 13/1 on all  sampling occasions,
     suggesting nitrogen limitation in the lake (a mean N/P ratio of
     14/1 or greater generally  reflects phosphorus limitation).

                                  12
IV.   NUTRIENT LOADINGS
     (See Appendix D for data)
          For the determination  of nutrient  loadings,  the  Idaho  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 month of 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 Idaho 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  tributaries
     are  those measured minus known point  source loads, if any.
          Nutrient loadings  for  unsampled  "minor tributaries and immediate
     drainage" ("ZZ" of USGS) were estimated by using  the  mean annual
                             2
     nutrient loads, in kg/km /year, in  Big  Elk Creek,  Indian Creek  and
     McCoy Creek at Stations D-l,  E-l and  F-l and  multiplying the means
                         2
     by the ZZ area in  km .
          Nutrient loads for the Jackson 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  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 Vollenwieder'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.

                   PARAMETRIC RANKINGS OF LAKES
                      SAMPLED BY NES IN 1975

                          STATE OF IDAHO
     Mean or median values for six of the key parameters  evaluated
in establishing the trophic conditions of Idaho lakes  sampled  are
presented to allow direct comparison of the ranking,  by parameter,
of each lake relative to the others.  Median total  phosphorus, median
inorganic nitrogen and median dissolved orthophosphorus levels are
expressed in mg/1. Chlorophyll a^ values are expressed  in  yg/1.
To maintain consistent rank order with the preceding  parameters,
the mean Secchi disc depth, in inches, is subtracted  from 500.
Similarly, minimum dissolved oxygen values are subtracted from 15
to create table entries.
