                          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
     V
    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.

-------
                                Ill
     Beyond the single lake analysis, broader based correlations
between nutrient concentration (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 & Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the California State Water
Resources Control Board and the nine Regional Water Quality
Control Boards for professional involvement, to the California
National Guard for conducting the tributary sampling phase of
the Survey, and to those California wastewater treatment plant
operators who voluntarily provided effluent samples and flow
data.

     The staff of the Division of Planning and Research of the
State Water Resources Control Board provided invaluable lake
documentation and counsel during the Survey, coordinated the
reviews of the preliminary reports, and provided critiques
most useful in the preparation of this Working Paper series.

     Major General Glen C. Ames, the Adjutant General of Cali-
fornia, and Project Officer Second Lieutenant Terry L. Barrie,
who directed the volunteer efforts of the California National
Guardsmen, are also gratefully acknowledged for their assistance
to the Survey.

I.    CONCLUSIONS
      A.    Trophic Condition*:
               Survey data indicate Lake Amador  is  eutrophic.   It  ranked
           twentieth in overall  trophic quality  when  the  24  California
           lakes and reservoirs  sampled in  1975  were  compared  using  a
           combination of six parameters**.   Fifteen  of the  waterbodies
           had less median total  phosphorus,  17  had less  median dissolved
           orthophosphorus,  22  had less median inorganic  nitrogen, 21 had
           less mean chlorophyll  ja, and 13  had greater mean  Secchi disc
           transparency.   Marked  depression  of oxygen with depth occurred
           at both sampling  stations in June and November.
               Survey limnologists did  not  observe  macrophytes or  surface
           concentrations of algae at any of the sampling times.   However,  the
           chlorophyll a^ concentration  at station 1 in November is indi-
           cative of a bloom condition.
      B.    Rate-Limiting  Nutrient:
               The results of the algal assay indicate the reservoir was phos-
           phorus limited at the  time the sample was  taken (03/14/75).
           The reservoir data indicate  phosphorus limitation in March and
           June and nitrogen limitation in  November.
      C.    Nutrient Controllability:
               1.   Point sources—The  contribution of known point sources
           amounted to 68.4% of the total phosphorus  load to Lake  Amador
* Trophic assessment is based on  levels of  nutrients, dissolved oxygen, and
  chlorophyll a; phytoplankton  kinds and numbers; and transparency (Allurn
  et al., 1977J
** See Appendix A.

-------
during the sampling year.   The City of Jackson added 67.6%
of the total load, and Argonaut Heights added 0.8%.
    The present phosphorus loading of 2.45 g/m2/yr is more
than twice that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading (see page 11 ).   If 90%
phosphorus removal is provided at Jackson, the reduced load-
ing will be just equal to the eutrophic loading (0.96 g/m2/yr).
If a higher degree of removal can be achieved at the Jackson
plant, the trophic condition of the reservoir should improve
once a new phosphorus equilibrium is established.
    2.   Non-point sources—Non-point sources, including direct
precipitation, added 31.6% of the total phosphorus load to
the reservoir during the sampling year.  Jackson Creek contributed
22.5% of the total, and the ungaged tributaries added an
estimated 8.4%.
    The phosphorus export rate of Jackson Creek was  8 kg/km2/yr
(see page 10).

III.  WATER QUALITY SUMMARY
      Lake Amador 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 enu-
meration; and during the first visit, a single 18.9-liter depth-inte-
grated sample was composited for algal assays.  Also each time, a depth-
integrated sample was collected from each of the stations for chloro-
phyll a^ analysis.  The maximum depths sampled were 44.2 meters at station
1 and 42.7 meters at station 2.
      The sampling results are presented in full in Appendix D and are
summarized in the following table.

     2.   Discussion -
              The control  yield of the assay alga, Selenastrum capri-
         cornutum, indicates that the potential  primary productivity
         of Lake  Amador was high at the time the sample was col-
         lected (03/14/75).  Also, a significant increase in yield
         with the addition of phosphorus alone indicates  that the
         reservoir was limited  by phosphorus  at  that  time.   Note  that
         the addition of nitrogen alone resulted in a yield no
         greater  than that of the control.
              The reservoir data indicate  phosphorus  limitation in March
         and June but nitrogen limitation  in November.   The mean
         inorganic nitrogen to orthophosphorus ratios were 15 to  1
         in March, 25 to 1 in June, and 8  to 1 in November (phos-
         phorus limitation is expected at  N to P ratios of 14 to  1
         or greater).

IV.   NUTRIENT LOADINGS
      (See Appendix E for data.)
      For the determination of nutrient loadings, the California 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 March and May when two samples were collected.   Sam-
pling 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 California District Office of the U.S. Geological Survey for the
tributary sites nearest the reservoir.
      Except for the aqueduct, nutrient loads for sampled tributaries were
determined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*.  Loads for the unnamed
aqueduct were calculated using mean annual flows and mean annual con-
centrations in Jackson Creek at station A-l.  Nutrient loads shown are
those measured minus point-sources loads, if any.
      Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the nutrient loads
at station A-2, in kg/km,2/year, and multiplying by the ZZ area in km2.
      The operators of the Jackson and Argonaut Heights wastewater
treatment plants provided monthly effluent samples and corresponding
flow data.

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.

     (g/m2/yr)  based on mean depth  and mean
     hydraulic  retention time of Lake Amador:
        "Dangerous"   (eutrophic loading)           0.96
        "Permissible"  (oligotrophic  loading)      0.48
