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 that Lake Hennessey is eutrophic. It
ranked fifteenth in overall trophic quality when the 24 Cali-
fornia lakes and reservoirs sampled in 1975 were compared using
a combination of six parameters**. Twelve of the waterbodies
had less median total phosphorus, nine had less and five had
the same median inorganic nitrogen, eleven had less median
dissolved orthophosphorus, eleven had less mean chlorophyll a^
and 14 had greater mean Secchi disc transparency. Significant
depression of dissolved oxygen with depth occurred at all three
sampling stations in June, and depletion occurred at station 1
in November.
Survey limnologists did not observe surface concentrations
of algae, but noted emergent macrophytes along much of the
shoreline in June. However, it is reported that a copper formu-
lation, Cutrine, is applied periodically to control problem
growths of algae (Bailey, 1977).
B. Rate-Limiting Nutrient:
The results of the algal assay indicate nitrogen limitation
in November. The reservoir data indicate nitrogen limitation
all three sampling times.
* 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 municipal wastewater treatment plants
are known to have impacted Lake Hennessey during the sampling
year, although the Angwin facilities may have contributed
to the phosphorus load (see discussion below).
The present phosphorus loading of 1.46 g/m2/yr is more
than twice that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading (see page 12), and every
effort should be made to minimize the input of phosphorus
to slow the aging of the reservoir.
2. Non-point sources--Non-point sources, including direct
precipitation, apparently contributed all of the total phosphorus
load to the lake during the sampling year. Conn Creek added 68.5%
of the total phosphorus load; Chiles Creek, 7.4%; Clear Creek,
10.4%; and the ungaged tributaries contributed an estimated
12.5%.
The phosphorus export rates of Conn Creek, Chiles Creek,
and Clear Creek were 106, 8, and 15 kg/km2/yr, respectively
(see page H).
The export rate of Conn Creek was very high compared to
the other tributaries and may be due to point source impact.
The community of Angwin is served by a series of stabilization
ponds that normally do not overflow to Conn Creek (Kramer, 1976).
However, precipitation and flow data indicate higher than nor-
mal runoff during the sampling year, and it appears likely
that some overflow from the Angwin ponds to Conn Creek did occur.

III. WATER QUALITY SUMMARY
Lake Hennessey was sampled three times in 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 in
March and three stations in June and November (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 last visit, a single 18.9-liter depth-integrated
sample was composited for algal assays. Also each time, a depth-integra-
ted sample was collected from each of the stations for chlorophyll a_
analysis. The maximum depths sampled were 26.2 meters at station 1, 13.1
meters at station 2, and 8.5 meters at station 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

2. Discussion - v
The control yield of the assay alga, Selenastrum capri-
cornutum. indicates that the potential primary productivity
of Lake Hennessey was high at the time the sample was taken
(11/11/75). Also, the significant increase in yield when
nitrogen was added alone, and the lack of response when
only phosphorus was added, indicate nitrogen limitation
at that time.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the California National
Guard collected monthly nea-r-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the high
runoff month of March when two samples were collected. 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'1 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
Sage Creek at station K-l and the mean annual ZZ flow.
No wastewater treatment plants are known to have impacted Lake
Hennessey during the sampling year.

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.
