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.
-------
1-11
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.
ACKNOWLEDGEMENT
The staff of the National Eutrophication Survey (Office of
Research and Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the Utah Department of Social
Services and the Utah Department of Natural Resources for pro-
fessional involvement, to the Utah National Guard for conducting
the tributary sampling phase of the Survey, and to those Utah
wastewater treatment plant operators who voluntarily provided
effluent samples and flow data.
The staffs of the Bureau of Water Quality of the Division
of Health and the Division of Wildlife Resources provided inval-
uable lake documentation and counsel during the Survey, reviewed
the preliminary reports, and provided critiques most useful in
the preparation of this Working Paper series.
Major General Maurice L. Watts, the Adjutant General of Utah,
and Project Officer Lt. Colonel T. Ray Kingston, who directed the
volunteer efforts of the Utah National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Willard Reservoir is eutrophic.
It ranked eighteenth in overall trophic quality among the 27
Utah lakes and reservoirs sampled in 1975 when compared using
a combination of six water quality parameters*. Sixteen of the
water bodies had less and one had the same median total phos-
phorus, 18 had less and one had the same median dissolved ortho-
phosphorus, 14 had less and one had the same median inorganic
nitrogen, 15 had less mean chlorophyll a., and 23 had greater
mean Secchi disc transparency. Some depression of dissolved
oxygen with depth occurred at station 2 in August (4.0 mg/1 at
1.5 meters).
Survey limnologists noted surface algal scums at all four
sampling stations in May and September.
B. Rate-Limiting Nutrient:
The algal assay results are not considered representative of
conditions in the reservoir at the times the samples were collected
(05/14/75 and 09/23/75). However, the reservoir data indicate
nitrogen limitation at all sampling stations and times.
C. Nutrient Controllability:
1. Point sources—It is estimated that the Southern Pacific
Railroad wastewater treatment facility contributed 1.3% of the

total phosphorus load to Willard Reservoir during the sampling
year, assuming all of the phosphorus discharged reached the
reservoir. However, the effluent is discharged to the Weber
River southeast of the reservoir and would impact the reservoir
only when river water is diverted at Slaterville Into Willard
Canal and thence into the reservoir.
Personnel of the Utah Bureau of Environmental Health report
that Willard Canal essentially has a zero gradient, and water
can be diverted into or pumped out of the reservoir via the
canal; however, water is pumped out only infrequently to insure
the pumps are operating properly (Hinshaw, 1976; Tate, 1976).
The flow data provided by the U.S. Geological Survey indicate
diversion into the reservoir only in May and in June of the
sampling year (see Appendix C). If no diversion occurred at
other times, the phosphorus contribution of the railroad
facility was much less than the indicated 1.3%.
The phosphorus loading of 0.21 g/m2 measured during the
sampling year is less than that proposed by Vollenweider
(Vollenweider and Dillon, 1974) as a eutrophic loading (see
page 12), but the trophic condition of the reservoir indicates
the loading ordinarily is greater than that; i.e., it would be
expected that a higher loading would result in years during
which more frequent diversions to the reservoir via Willard
Canal occurred.
2. Non-point sources—Non-point source contributed nearly
all of the phosphorus inputs to the reservoir during the sam-
-------
3
pi ing year. The Willard Canal accounted for 84.4% of the total
load, and the remaining six gaged tributaries collectively con-
tributed 5.8%.

III. WATER QUALITY SUMMARY
Mil lard 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 num-
ber of depths at four stations on the reservoir (see map, page v). Dur-
ing each visit, a single depth-integrated (4.6 m or near bottom to sur-
face) sample was composited from the stations for phytoplankton identi-
fication 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 4.0 meters
at station 1, 4.9 meters at station 2, 5.5 meters at station 3, and 5.2
meters at station 4.
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 times the samples were collected
(05/14/75 and 09/23/75) due to significant changes in the nutrient
concentrations in the samples during shipment from the field to
the laboratory.
The reservoir data indicate nitrogen limitation all three sam-
pling times. The mean inorganic nitrogen/orthophosphorus ratios
were 6/1 in May, 4/1 in August, and 11/1 in September, and nitro-
gen limitation would be expected.
Nitrogen limitation, as indicated by the algal assay or by in-
reservoir nitrogen to phosphorus ratios, does not necessarily mean
that the trophic condition of the reservoir can be improved by
controlling nitrogen inputs. In many cases, the apparent condition
of nitrogen-limitation results from excessive phosphorus input
from point sources and is often accompanied by a corresponding
increase in primary production. In such cases, the reversal of
the enriched condition depends upon phosphorus control, not
nitrogen control.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Utah National Guard
collected monthly near-surface grab samples when possible from each of
the tributary sites indicated on the map (page v). Sampling was begun
in November, 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 Utah
District Office of the U.S. Geological Survey for the tributary sites
nearest the reservoir.
In this report, nutrient loads for sampled tributaries were calculated
using mean annual concentrations and mean annual flows. Nutrient loads
shown are those measured minus point-source loads, if any.
The operator of the Southern Pacific Railroad wastewater treatment
facilities provided monthly effluent samples and corresponding flow data.

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 ma^y not be applicable to
water bodies with short hydraulic retention times.
