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.
ACKNOWLEDGMENTS
The staff of the National Eutrophication Survey (Office of
Research and Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the Idaho Department of Health
and Welfare for professional involvement, to the Idaho National
Guard for conducting the tributary sampling phase of the Survey,
and to those Idaho wastewater treatment plant operators who pro-
vided effluent samples and flow data.
The staff of the State of Idaho Department of Health and
Welfare, Division of Environment, provided invaluable lake docu-
mentation and counsel during the Survey, reviewed the preliminary
reports and provided critiques most useful in the preparation of
this Working Paper Series.
Major General James S. Brooks, Adjutant General of Idaho, and
Project Officer Major Vestal L. Baker, who directed the volunteer
efforts of the Idaho National Guardsmen, are also gratefully

STORE! NO. 1610
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).

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.
Total Yearly
Phosphorus Loading
(g/m2/yr)
Estimated loading for Palisades Reservoir 6.25
Vollenweider's "eutrophic" loading 1.84
Vollenweider's "oligotrophic" loading 0.92

APPENDIX E
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.
