                          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)]s
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 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 that Tullock Reservoir is eutrophic.
        It ranked eleventh in overall trophic quality when the 24 Cali-
        fornia lakes and reservoirs sampled in 1975 were compared
        using a combination of six parameters**.   Eleven of the water
        bodies had less median total  phosphorus,  ten had less median
        dissolved orthophosphorus, nine  had less  and five had the same
        median inorganic nitrogen, 19 had less mean chlorophyll a^, and
        15 had greater mean Seechi disc  transparency.  Significant
        depression of dissolved oxygen with depth did not occur at any
        station or sampling time.
            Survey limnologists did not  observe macrophytes or surface
        concentrations of algae.  However, the chlorophyll a^ concen-
        tration at station 3 in November (64.2 pg/1) indicates a
        possible bloom condition there at that time.
    B.   Rate-Limiting Nutrient:
            Due to significant changes in nutrients in the samples
        during shipment from the field to the laboratory, the algal
        assay results are not considered representative of conditions
        in the reservoir at the times the samples were taken.
            The reservoir data indicate  nitrogen  limitation in March
        and June and phosphorus limitation in November.
* Trophic assessment is based on levels of nutrients,  dissolved oxygen,  and
  chlorophyll a^ phytoplankton kinds and numbers;  and  transparency (Allurn
  et al., 1977.
** See Appendix A.

-------
C.   Nutrient Controllability:
        1.   Point sources—No  known municipal  wastewater  treatment
    plants impacted Tullock Reservoir during  the  sampling year.
    Septic tanks serving shoreline dwellings  were estimated  to  have
    contributed 0.1% of the total  phosphorus  load,  but  a  shoreline
    survey is needed to determine  the significance  of those  sources.
        The present phosphorus loading of 7.34 g/m2/yr  is a  little
    more than twice that proposed  by Vollenweider (Vollenweider and
    Dillon, 1974) as a eutrophic loading  (see page  11).   However, the
    mean hydraulic retention time  of the  reservoir  is a short 19
    days, and Vollenweider's model  probably is not  applicable.
        2.   Non-point sources--Non-point  sources, including  direct
    precipitation, added 99.9% of  the total phosphorus  load  to  the
    reservoir during the sampling  year.   The  Stanislaus River
    contributed 92.4% of the total  load;  Black Creek, 0.5%;  and
    the ungaged tributaries, an estimated 6.9%.
        The phosphorus export  rates of the Stanislaus River  and
    Black Creek were 15 and 3  kg/km2/yr,  respectively (see page 10).

III.    WATER QUALITY SUMMARY
    Tullock 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 three 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 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  £ analysis.  The maximum depths sampled were
45.1 meters at station 1, 35.4 meters at station 2, and 32.3 meters
at station 3.
    The sampling results  are presented in full  in Appendix D and are
summarized in the following table.

C.   Limiting Nutrient Study:

        The algal  assay results are not considered representative of

    conditions in  the reservoir at the time of sample collection be-

    cause of significant changes in the nutrients  in the samples

    during shipment from the  field to the laboratory.

        The reservoir data indicate nitrogen limitation in March and

    June and phosphorus limitation in November.  The mean inorganic

    nitrogen to orthophosphorus ratios were 6 to 1 in March, 8 to 1

    in June, and 20 to 1 in November.

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).  Sampling 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.
    In this report, nutrient loads for sampled tributaries were cal-
culated using mean annual concentrations and mean annual flows.  Nu-
trient loads for unsampled "minor tributaries and immediate drainage"
("ZZ" of U.S.G.S.) were estimated using the mean concentrations in Green
Spring Run at station B-l and the mean annual ZZ flow.
    No known wastewater treatment plants impacted Tullock Reservoir
during the sampling year.

    the inclusion of an erroneous value (0.120 mg/1 on 05/12/75) in the
    calculation of the outlet load at station A-l.

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,

    Vollenweider phosphorus loadings
     (g/m2/yr) based on mean depth and mean
     hydraulic retention time of Tullock Reservoir:

        "Permissible"   (oligotrophic loading)      1.70
