                          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.

-------
                                m
     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 Fallen Leaf Lake is oligotrophic.   It
        ranked second in overall trophic quality when the 24 California
        lakes and reservoirs sampled in 1975 were compared using a
        combination of six parameters**.  None of the other water bodies
        had less median total  phosphorus,  seven had less  median  dis-
        solved orthophosphorus,  none of the others had less but  four
        had the same median inorganic nitrogen, and none  of the  others
        had less chlorophyll a^or greater mean Secchi disc trans-
        parency.  No significant depression of dissolved  oxygen  with
        depth occurred at any of the sampling stations or times.
            Survey limnologists  did not observe macrophytes or surface
        concentrations of algae  at any time.
    B.   Rate Limiting Nutrient:
            Due to significant nutrient changes in the algal  assay
        samples during shipment  from the field to the laboratory, the
        results are not considered representative of conditions  in  the
        lake at the times the samples were taken.
            The lake data indicate nitrogen limitation in March  and June
        but 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., 1977J.
** See Appendix A.

-------
C.   Nutrient Controllability:
        1.   Point sources—No  known municipal  or  industrial waste-
    water plants impacted Fallen Leaf Lake during the  sampling
    year.  Septic tanks serving lakeshore  dwellings  contributed
    an estimated 7.9% of the total  phosphorus  load,  but  a  shore-
    line survey is needed to determine the significance  of those
    sources.
        The present phosphorus load of 0.11  g/m2/yr  is less
    than that proposed by Vollenweider (Vollenweider and Dillon,
    1974) as an oligotrophic load (see page 12) and  every  effort
    should be made to prevent  any increase in  phosphorus inputs
    to protect the existing high quality of Fallen Leaf  Lake.
        2.   Non-point sources—Non-point sources, including
    direct precipitation, contributed 92.1% of the total phos-
    phorus load reaching the lake during the sampling year.
    Glen Alpine Creek added 56.7% of the total  load, and the un-
    gaged tributaries contributed an estimated 19.7%.
        The non-point phosphorus export rate of Glen Alpine
    Creek was 13 kg/m2/yr (see page 11).

III.    WATER QUALITY SUMMARY
    Fallen Leaf Lake 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 five stations in March and November and
from four stations in June (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 a^ analysis.   The maximum depths sampled were 59.7
meters at station 1, 21.3 meters at station 2, 68.6 meters at stations 3
and 4, and 61.0 meters at station 5.
    The sampling results are presented in full in Appendix D and are
summarized in the following  table.

C.   Limiting Nutrient Study:

        Due to significant changes in nutrients in the samples,

    the algal  assay results are not considered representative of

    conditions in the lake at the times the samples were collected

    (03/18/75 and 11/4/75).

        Overall,  the lake data indicate that Fallen Leaf Lake was

    nitrogen limited in March and June but phosphorus limited in

    November.   The mean inorganic nitrogen to orthophosphorus ratios

    were 5 to 1  in March, 6 to 1 in June, and 20 to 1 in November.

        Following is a tabulation of the mean N to P ratios  for

    each station  and sampling time, with indicated limiting  nutrient

    in parentheses.

    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, April, and June when two samples were collected
at the outlet.  Sampling was begun in November, 1974, and was completed
in October, 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 lake.
    In this report, nutrient loads for sampled tributaries were de-
termined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*.  Nutrient loads for unsampled
"minor tributaries and immediate drainage" ("ZZ" of U.S.G.S.) were
estimated using the nutrient loads, in kg/km2/year, at station B-l,
and multiplying by the ZZ area in km2.
    No known wastewater treatment plants impacted Fallen Leaf Lake
during the sampling year.

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 Fallen Leaf Lake:
        "Dangerous"   (eutrophic loading)            0.56
        "Permissible"   (oligotrophic loading)       0.28
