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 ANALYSI
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 p'larming [§303(c)], 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.
-------
iii
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (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.

STORE! NO. 4101
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate Brownlee Reservoir is eutrophic.
It ranked twentieth in overall trophic quality when the 21
Oregon and Idaho lakes and reservoirs sampled in 1975 were com-
pared using a combination of six water quality parameters*.
Eighteen of the water bodies had less median total phosphorus,
dissolved orthophosphorus, and inorganic nitrogen; 17 had less
mean chlorophyll £; and 15 had greater mean Secchi disc trans-
parency. Marked depression of dissolved oxygen with depth
occurred at sampling stations 2, 3, and 4 in August and at
stations 2 and 3 in September, and depletion occurred during
a previous study of the reservoir (Ebel and Koski, 1968).
Survey limnologists reported surface concentrations of
algae at station 1 in September. The concentrations of chlorophyll
a^ at stations 2, 3, 4, and 5 in April (see page 7) indicate
possible bloom conditions at that time as well.
B. Rate-Limiting Nutrient:
The algal assay results are not considered representative of
conditions in the reservoir at the time the samples were col-
lected (04/19/75 and 09/15/75) due to significant nutrient
changes during shipment of the samples from the field to the
laboratory.
* See Appendix A.
-------

The reservoir data indicate phosphorus limitation at four
of the five sampling stations in April, nitrogen limitation at
four of the stations in August, and nitrogen limitation at all
stations in September.
C. Nutrient Controllability:
1. Point sources—The wastewater treatment plants at Hun-
tington, Oregon, and Weiser, Idaho, collectively contributed
an estimated 0.2% of the total phosphorus load to Brownlee
Reservoir during the sampling year. However, other municipal
and industrial point sources in the drainage basin beyond the
40-kilometer limit of the Survey* probably are significant
contributors (see page 10).
The sampling year phosphorus loading of 33.47 g/m2 is nearly
ten times that proposed by Vollenweider (Vollenweider and Dil-
lon, 1974) as a eutrophic loading (see page 14). Although
Vollenweider's model may not be applicable to water bodies with
.short hydraulic retention times, the trophic condition of Brownlee
Reservoir is evidence of excessive nutrient loads.
2. Non-point sources—As considered in this report, "non-
point" sources include those contributing nutrients as a result of
human activities (e.g., agricultural practices, urbanization,
extractive processes, etc.) as well as natural sources (i.e.,
direct precipitation, leaf fall, wild birds and animals, etc.).
The apparent non-point source contribution accounted for 99.8%
* See Working Paper No. 175, "...Survey Methods, 1973-1976".
-------
3
of the total phosphorus load during the sampling year. However,
as noted above, part of this load is attributable to point sources
further upstream.
The Snake River contributed 95.3% of the total phosphorus
load, the Powder River contributed 2.0%, and four other gaged
tributaries collectively contributed 2.2%. The ungaged minor
tributaries and immediate drainage contributed an estimated 0.2%.
While substantial point-source inputs occur upstream on
the Snake River, in a previous report it is noted that up to
44% of the nutrient load in the river comes from agricultural
sources (Anonymous, 1974). Also, in Oregon, agricultural runoff
and irrigation return flows have been noted as the major contributors
to the nutrient loads in the Burnt, Powder, and Pine rivers (Anony-
mous, 1969). Any improvement in the trophic condition of Brownlee
Reservoir would involve minimization of nutrients from the non-
point as well as point sources in the drainage basin.

III. WATER QUALITY SUMMARY
Brownlee 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 five 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 samples were 18.9 meters
at station 1, 64.0 meters at station 2 and 3, 32.3 meters at station 4,
and 18.6 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:
The algal assay results are not considered representative of
conditions in the reservoir at the time the samples were taken
(04/09/75 and 09/15/75) due to significant nutrient changes in
the samples during shipment from the field to the laboratory.
The reservoir data indicate a combination of limiting nutrients.
Following is a tabulation of the mean inorganic nitrogen/ortho-
phosphorus ratios for each of the sampling stations and times
with the indicated limiting nutrient in parentheses.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Oregon 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 January and February 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 Oregon District Office of the U.S. Geological Survey for the tribu-
tary sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate drain-
age" ("II" of U.S.G.S.) were estimated using the means of the nutrient
loads, in kg/km2/year, at stations G-l and K-l and multiplying the means
by the II area in km2.
The operators of the Huntington, OR and Weiser, ID wastewater treat-
ment plants did not participate; nutrient loads from these sources were
estimated at 1.134 kg P and 3.401 kg N/capita/year, and flows were esti-
mated at 0.3785 m3/capita/day.

Ontario, and Baker, Oregon, most of these plants discharge into
the Snake River and its tributaries in Idaho.
2. Known industrialt--At least 31 industries are known
to discharge within the drainage basin in Oregon and Idaho.
These include sugar-beet, potato, and other agricultural pro-
cessing plants; fish hatcheries; car washes; timber processing;
a phosphate reduction plant; and a cement plant.

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.
