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)],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
Ill
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Bear Lake is oligotrophic. It
ranked first in overall trophic quality when the 27 Utah lakes
sampled in 1975 were compared using a combination of six water
quality parameters*. Two lakes had less and two had the same
median total phosphorus, one had less and three had the same
median dissolved orthophosphorus, none had less and ten had the
same median inorganic nitrogen, none had less mean chlorophyll £,
and only one other lake had a greater mean Secchi disc transparency.
Survey limnologists did not observe any nuisance conditions on
the lake during the three sampling visits. No significant depression
of dissolved oxygen with depth occurred at any of the sampling
stations or times.
B. Rate-Limiting Nutrient:
Because of nutrient changes in the samples, the algal assay
results are not representative of conditions in the lake at the
times the samples were collected (05/14/75 and 09/19/75). The
lake data indicate nitrogen limitation at all stations in May;
nitrogen limitation at stations 1, 5, and 6 but phosphorus limita-
tion at stations 2, 3, 4, and 7 in August; and phosphorus limita-
tion at all stations except station 3 in September.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources—No known municipal or industrial waste-
water treatment plants impacted Bear Lake during the sampling
year. Lakeshore septic tanks contributed an estimated 0.7% of
the total phosphorus load, but a shoreline survey would have to
be done to determine the actual significance of those sources.
The present phosphorus loading of 0.09 g/m2/yr is less than
that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as a eutrophic loading but is more than his suggested oligo-
trophic loading; i.e., it is a mesotrophic loading (see page 14).
If the existing oligotrophic characteristics of Bear Lake
are considered desirable, the loading should be reduced to the
oligotrophic loading level. If the present loading continues,
mesotrophic characteristics such as hypolimnetic depression or
depletion of dissolved oxygen will become increasingly evident.
However, changes in the trophic condition of the lake will not be
rapid or readily obvious on a year-to-year basis because of the
large volume of the lake and the lengthy mean hydraulic retention
time of nearly 22 years.
2. Non-point sources--Non-point sources contributed 99.3$ of
the total phosphorus load to Bear Lake during the sampling year.
Pumped return-flow loads from the outlet channel (station A-l)
contributed 48.1%, Big Creek contributed 9.5%, North Eden Canyon
-------
3
contributed 6.2%, Unnamed Creek E-l contributed 5.3%, and the
four other gaged tributaries collectively contributed 5.5% of
the total. Ungaged minor tributaries and immediate drainage
contributed an estimated 4.3%.
The Utah Power and Light Company operates the Lifton Pumping
Station at the outlet to return water from the outlet channel and
Dingle Swamp for peak power generation (Cogger, 1976). Since the
phosphorus load contributed by this operation is the major addition
to the total phosphorus loading of Bear Lake at the present time,
any reduction in pumpage would lessen the nutrient enrichment of
the lake.
In previous studies it has been noted that local land-use
practices may also contribute nutrients (Anonymous, 1975). Survey
data indicate that while the tributaries have relatively high total
phosphorus concentrations, the low or intermittent flows in most
of these streams result in relatively minor non-point contributions.
However, periodic heavy runoff could increase the loads in the
streams, depending on the kind of land-use practice involved. Fur-
ther study would be necessary to determine the controllability of
phosphorus contributions resulting from land-use practices in the
lake drainage.

III. LAKE WATER QUALITY SUMMARY
Bear 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 two
or more depths at seven stations on the lake (see map, page v).
During each visit, a single depth-integrated (4.6 m or near bottom
to surface) sample was composited from the stations for phytoplankton
identification and enumeration; and during the May and September
visits., 18.9-liter depth-integrated samples were 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 2.7 meters at station 1, 32.3 meters at station
2, 7.9 meters at station 3, 47.5 meters at station 4, 31.1 meters
at station 5, 24.7 meters at station 6, and 26.2 meters at station 7.
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 lake at the time of sampling (05/14/75 and 09/
19/75) due to significant changes in nutrients in the samples
during shipment from the field to the laboratory.
The lake data indicate nitrogen limitation at all stations
in May and a combination of limiting nutrients in August and
September. Following is a tabulation of the mean inorganic
nitrogen/orthophosphorus ratios at 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 Utah and Idaho
National Guards collected monthly near-surface grab samples from each
of the tributary sites indicated on the map (page v), except for the
months of May through August when two samples were collected at one or
more of the sites. Sampling was begun in October, 1974, and was com-
pleted 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 Utah District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
calculated using mean annual concentrations and mean annual flows.
Nutrient loadings for the outlet channel (station A-l) below Lifton
Pumping Station were calculated using normalized monthly flows and
mean nutrient concentrations. Negative flows (pumped return flows)
are shown as an additional inlet to the lake and positive flows as the
amount leaving the lake (see Appendix C).
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the mean concentrations
in Swan Creek at station G-l and the mean annual ZZ flow.

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 morphemetry 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.
