ABSTRACT
The quality of the waters in the Bear River Basin was surveyed
from August 27 to August 29, 1974. The purposes of the survey were
to determine point and non-point source loading, to determine whether
water quality has improved since the adoption of the 1958 Enforcement
Conference pollution control measures, to determine the cause and
effect relationships between major waste sources and receiving water
quality, and to determine whether major waste sources are complying
with their NPDES permits. Survey results show violations of Idaho
Water Quality Standards in these parameters: bacteria, turbidity, and
dissolved oxygen. Also, levels of Lindane, a chlorinated hydrocarbon
pesticide and mercury significantly higher than the recommended maximal
levels were found in the upper reaches of the Bear River. Although
sufficient data since 1958 was not available to evaluate the pollution
control measures, water quality changes in BOD's and Total Coliform
bacteria were noted. The Monsanto Co. was found to comply with their
NPDES permit in all but one area - there was an apparent temperature
violation. Nutrient loading was investigated and related to algal
productivity - but not all loading sources were located. Other findings
include realization that point sources did not appreciably affect the
quality of the Bear River except in very localized areas.

INTRODUCTION
Unlike most major rivers of the United States that flush pollutants
into the oceans, the Bear River discharges into the Great Salt Lake.
Because the Great Salt Lake has a limited capacity to assimilate
pollutants, it is important to identify and reduce the pollutant levels
entering the lake from the Bear River.
There have been no water quality surveys conducted on the Idaho
portion of the Bear River since 1955. As a consequence, little data
is available to define the present water quality of the Bear River Basin
as required by PL 92-500.
Region X of the Environmental Protection Agency conducted a water
quality survey on August 27,28 and 29 of 1974. The purposes of this
survey were to:
1. Determine the point source and non-point source loading during
the period when the most severe water quality problems exist.
2. Determine whether there has been an improvement in the Bear
River Basin water quality since the 1958 enforcement conference.
3. Expand the data base to support water quality standards
revisions, waste discharge permitting activities and future pollution
abatement actions.
4. Determine the cause and effect relationship between waste
sources and receiving water quality.
5. Determine whether major waste sources are in compliance with
the NPDES permits.
The results of this study are detailed in subsequent sections
of this report.

BEAR RIVER EVALUATION REPORT
SUMMARY
Findings and Conclusions
1. Idaho's water quality standards for bacteria, turbidity and
dissolved oxygen were violated during the August 1974 survey.
A. Class A and B fecal coliform bacteria standards were violated
in several tributaries to the Bear River as well as in Worm
Creek.
B. The 90% dissolved oxygen standards were violated periodically
throughout the Bear River system over the last six years.
C. Dramatic increases in turbidity levels in the Bear and Cub
Rivers suggest water quality standards violations; however,
the standards are difficult to apply due to the wide range
of interpretations of the standard.
2. Recommended water quality criterion (1) of 0.05 ug/1 for mercury
(Hg) was exceeded throughout the entire reach of the Bear River
in Idaho. Based upon survey data, there is a possibility of a
mercury buildup in the bottom of Alexander Reservoir.
3. During the August 1974 survey, the chlorinated hydrocarbon pesticide,
Lindane, exceeded the recommended criterion (1) of .005 ug/1 in the
Bear River. The highest levels of approximately .010 ug/1 occurred
in the vicinity of the Bear Lake outlet.
-9-
-------
4. There has not been ample data collected since the 1958 Bear
River Enforcement Conference to adequately document the effective-
ness of pollution control actions resulting from the conference;
however, the following water quality changes are apparent:
A. Biochemical Oxygen Demand (BODS) levels have increased in the
lower Bear River and decreased in the Cub River following the
enforcement conference.
B. Total coliform bacteria levels generally are higher in the
Bear and lower in the Cub River for the post conference
period.
C. The reduction of BOD5 and total coliform levels in the Cub
River apparently resulted from installation of treatment
facilities at Del Monte Corporation.
5. The compliance monitoring evaluation of Monsanto Company showed that
the company was generally in compliance with the initial effluent
limitations as specified in their NPDES permit except for an
apparent violation of the discharge temperature stipulation.
6. High levels of total and fecal coliform bacteria were infiltrating
the Mud Lake area from the Paris, Idaho septic tank drainfield
during the survey period.
7. High levels of fecal coliform bacteria and the presence of some
pathogenic bacteria were documented in Worm Creek below the Preston
STP indicating poor disinfection of the STP effluent.
8. Nutrient loading of the Cub River in the Franklin area cannot be
reconciled with the Del Monte discharge; apparently an unknown inflow
in that area adds a large percentage of loading to the Cub River.
10-
-------
9. The bacteriological data collected during the August 1974 survey
show that the domestic animal population along the Bear River has
a heavy bacterial impact on water quality. Livestock appears to be
the major source of warmblooded animal fecal contamination in this
portion of southeastern Idaho. Even though the pathogen recoveries
were more frequent near populated areas, the predominant source of
fecal waste contamination still appears to be animal in origin.
10. High total solids concentrations are predominant in the Bear River
basin. Most of the solids are dissolved with 20% to 30% of the total
being of organic nature. The solids increase significantly from the
Wyoming-Idaho to the Idaho-Utah border as the result of groundwater
and irrigation return inflow.
11. The greatest number of game fish caught in the Idaho Bear River
sustem occur from downstream of Soda Spring Reservoir to Grace
Powerhouse. The greatest catch per angler occurs in the area between
Grace Dam and Powerhouse where the only flow in the reach is from
groundwater inflow. These high catch reaches are characterized by
low turbidity and suspended solids. Alexander Reservoir apparently
settles out the suspended solids.
12. During the survey period point sources did not appreciably affect
water quality of the Bear River except in very localized areas.
Non-point sources from agricultural runoff and groundwater affect
the Bear River water quality to a greater extent.
The majority of the phosphorus in the Bear River Basin comes
from identifiable but non-controllable sources. The primary
11-
-------
phosphorus sources are springs throughout the lower river from
Alexander Reservoir to the Utah-Idaho border and Mud Lake, Georgetown
Creek, Soda and Spring Creeks.
During the survey period considerably more phosphorus and
suspended solids were being discharged from the Mud Lake area than
were entering. This was probably due to scouring caused by the high
volume of discharge from Bear Lake. Mud Lake at the same time was
acting as a sink for organic material and N03-N.
13. The potential for nuisance levels of algal productivity exists
in the reservoir areas of the Bear River. High phosphorus, pH,
and alkalinity levels as well as 120% to 130% daytime dissolved
oxygen saturation levels indicate an insipient algal production
problem in the slack water areas of the basin. Periphyton
chlorophyll a_ levels below Grace Power Plant indicate that the
water in that area can presently be classified as mesotrophic.
Recommendat ions
1. Permanent monitoring stations should be established at the
following locations:
A. Bear River at the Idaho-Wyoming Border
B. Bear River just below Soda Springs Reservoir
C. Bear River near the Idaho-Utah Border
D. Cub River near the Utah-Idaho Border
Sampling should be minimally on a monthly frequency.
-12-
-------
2. The following studies are needed based upon the results of the
August 1974 water quality survey:
A. More extensive surveys to evaluate the vertical water
column and bottom muds of Alexander and Oneida Reservoirs.
B. Evaluation of water quality during the non-irrigation
season in the Soda Springs vicinity to determine effect of
the Monsanto discharge.
C. Diurnal studies during the late summer for dissolved oxygen
in selected areas of the Bear River to assess actual water
quality standard violations.
D. Studies or research to determine what, if any, agricultural
management practices could be used to reduce the turbidity
and nutrient loading in the Bear River system.

BASIN DESCRIPTION
The Bear River, shown on Figure 1, drains approximately 6,800
square miles in three different states of which 2,350 square miles,
or 35 percent, is in the State of Idaho. The total length of the
river is approximately 500 miles; of which 160 miles, or 32 percent,
is in Idaho. After flowing some 500 miles from its source in the
Uinta Mountains of Utah and crossing state boundaries five times,
the river terminates in the Great Salt Lake, only 90 miles west from
its point of origin. Major tributaries to the Bear River in Idaho
are shown on Figure 1.
The Bear River Compact, approved by the U.S. Congress in 1958,
established a commission that administers the distribution of river
water among the states of Idaho, Utah, and Wyoming. The compact
stipulates the policy of the participating states to encourage additional
projects for the maximum beneficial use of the available Bear River
water.
The principal uses of water in the Bear River basin in order of
priority are hydroelectric power, irrigation, domestic, stock and
industrial purposes.
The Bear River enters Idaho near Border, Wyoming and flows in a
westwardly direction towards Stewart Dam where water is diverted by
canal into Mud Lake and then to Bear Lake. Bear Lake is approximately
70,400 surface acres in size and contains 1.4 million acre-feet of
water. The Lifton Pumping Plant located at the north end of Bear Lake
was constructed in 1914 to control the water level in Bear Lake and
thereby regulate flows into the Bear River for downstream power
generation and irrigation purposes. The pumping station contains no
-14-
-------
power producing facilities.
Between the north end of Bear Lake and the city of Soda Springs,
the river meanders through rolling farm and grazing lands. Near Soda
Springs the river enters a narrow channel which it has cut through the
lava. Alexander Reservoir, also called Soda Reservoir or Soda Point
Reservoir, and its associated hydroelectric plant are located in this
lava channel. The Alexander power plant was constructed in 1924, is
operated by the Utah Power and Light Company, and contains a total
installed generating capacity of 14,000 kilowatts. At capacity,
Alexander Reservoir covers approximately 1,007 surface acres and
contains 15,000 acre-feet of water.
West of Alexander Reservoir, the river passes Alexander Point
and makes a sharp turn to the south where it enters Gem Valley. In
Gem Valley, the river passes Last Chance Dam which is a mains tern
irrigation diversion structure: the river then flows into the Grace
Reservoir. Grace Reservoir was constructed in 1923 and contains
approximately 200 acre-feet of water at capacity. At the Grace Dam
the river water is diverted into a flume and sent cross-country for
approximately 4.5 miles to the Grace Power Plant. This facility was
constructed in 1923 and is operated by the Utah Power and Light Company.
It has a total installed generating capacity of 31,000 kilowatts.
From the Grace Dam to the Grace Power Plant, the river is located
in a steep walled canyon known locally as Black Canyon. When all river
water is being diverted at the Grace Dam, flows in the Black Canyon
consist almost entirely of spring water. It has been suggested that
springs which arise in the Black Canyon are the result of leakage
from the river between Alexander Dam and the Grace Dam.
-15-
-------
Immediately downstream from the Grace Power Plant is the Cove
Pond. At capacity, this pond is approximately five surface acres in
size and contains 25 acre-feet of water. It serves as an equalizing
reservoir and point of diversion for water which is used at the Cove
Power Plant located approximately two miles downstream. Water demands
by the Utah Power and Light Company's Cove Plant, which has an installed
generating capacity of 7,000 kilowatts, render the river virtually
unfishable between the Cove Pond and power plant.
Downstream from the Cove Power Plant, the river meanders through
Gentile Valley and Mound Valley and enters Oneida Narrows Reservoir near
the small community of Cleveland. Oneida Reservoir and associated
power plant is located in the upstream portion of a narrow canyon
(Oneida Narrows) which is about 11 miles in length. At capacity, the
reservoir covers approximately 480 surface acres and contains 11,485
acre-feet of water. This facility was constructed in 1920, is
operated by the Utah Power and Light Company, and has a total installed
generating capacity of 30,000 kilowatts. Water flows in the river
downstream from the dam vary daily, depending on power demands at high
flows. Because of this, fishing downstream of Oneida Reservoir is
virtually impossible.
Downstream from Oneida Narrows, the river enters Cache Valley and
leaves Idaho near the small community of Weston.
Figure 2 shows the hydrology of the Bear River at three stations
for a data period of 1969 to 1973. Maximum river discharge normally
occurs between March and July of each year ostensibly to satisfy
irrigation needs downstream. The large difference in flow between
maximum and minimum flows is the result of flow regulation at the dam
for power and irrigation purposes.

PREVIOUS STUDIES
Following is a list of water quality or related studies that
have been conducted on the Bear River over the past twenty years:
1. In 1953, the States of Idaho and Utah conducted joint
bacteriological studies of streams in the Idaho-Utah border area.
More than 200 stream samples were collected at about fifteen stations
in this area and coliform organism numbers were determined. These
studies were made during March, June, and Sept., and consisted of a
one-week's series of samples and tests in each of these months.
2. In 1954, United States Public Health Service (USPHS) personnel
conducted a study of the Bear River and some of its tributaries from
the Idaho-Utah border area to its mouth. The purpose of this study
was to ascertain the effects, especially biological, of the cannery and
sugar refinery wastes on the stream. A one-week study was made in
August during the operating season of the canneries and another study
of one week was made in November when the sugar refineries were in
operation. In addition to detailed biological population analyses,
temperature, turbidity, pH, alkalinity, and dissolved oxygen were
determined.
3. From November 7 to December 9, 1955, a joint State-Federal
study of water quality and industrial waste characteristics was made
in the Idaho-Utah border area to obtain physical, chemical, and
bacteriological data which Utah could use in classifying streams and
ascertaining waste abatement needs. The study included analyses of
-18-
-------
10 samples from each of 14 stations. Stream flows also were determined
with the aid of the United States Geological Survey (USGS). Industrial
waste studies also were made at three beet sugar refineries and two
dairies. The 1955 study provided data which enables a reasonably
complete analysis of the problem during the sugar refining season.
4. Idaho Fish and Game Department (IFG) conducted a fish creel
census in the Idaho portion of the Bear River in 1972 and 1973. A
report titled "Returns of Planted Rainbow Trout, Fishing Pressure and
Catch in the Bear River and Fish Populations in Mains tern Reservoirs
and Tributary Streams" was published in June 1974.

1958 BEAR RIVER ENFORCEMENT CONFERENCE SUMMARY
On October 8, 1958, the first session of a two session enforcement
conference on pollution of interstate waters of the Bear River was
convened at the request of the Utah Water Pollution Control Board. The
Surgeon General of the Public Health called the conference under
provisions of Section 8 of the Federal Pollution Control Act because
it was feared that pollution occurring in Idaho was endangering the
health and welfare of persons in the State of Utah.
At the conclusion of the first session, the conference unanimously
made the following conclusions and recommendations:
1. The Bear River is an interstate stream within the meaning of
the Federal Water Pollution Control Act.
2. The Bear River, as it flows back and forth from Wyoming and
Utah in the Evans ton area, may present a potential minor pollution problem.
3. Pollution of interstate waters subject to abatement under the
Federal Water Pollution Control Act is occurring in the Bear River and
its tributary, the Cub River, as they flow from Idaho to Utah.
Municipal and industrial wastes from Preston, Idaho, the Franklin Sugar
Company at Whitney, Idaho, and the California Packing Company at
Franklin, Idaho, are finding their way into the waters of the Bear River.
There they combine with waste from the Amalgamated Sugar Company at
Lewiston, Utah, the Cache Valley Creamery at Lewiston, Utah, the
community of Lewiston, Utah, the Sego Milk Company at Richmond, Utah,
the California Packing Company and the Rocky Mountain Dairy Company at
-20-
-------
Smithfield, Utah, the California Packing Company, E.A. Miller Packing
Company, L.L. Miller Packing Company and the Morning Mild Company at
Wellsville, Utah, the Community of Wellsville, Utah, and the City of
Logan, Utah, which are also finding their way into the waters of the
Bear River.
4. Such discharges from Idaho contribute to the pollution of
the Bear River so as to endanger the health and welfare of persons in
Utah, a State other than that in which the discharges originate. The
effects of this pollution are:
A. Deterioration of water quality used for irrigation and
stock watering so as to cause a potential health hazard.
B. Deterioration of water quality so as to interfere with
aquatic life and fishlife.
C. Deterioration of water quality so as to interfere with the
Cache River Basin area as a recreational area.
D. Deterioration of the river so as to make it unsuitable as a
potential source of public water supply.
5. The State of Utah, with the advice and assistance of the USPHS
was to gather information and data which would permit the State of Utah
to classify the waters of the Bear River under the Utah State Law.
The second session of the conference was held on July 19, 1960
and ended with the recommendation that representatives from the states of
Idaho and Utah meet and establish a time schedule for specific remedial
action by the municipal and industrial dischargers in the Bear River
area of concern.
-21-
-------
Shortly after the conference ended, Idaho obtained commitment
letters from the municipal and industrial dischargers and worked out
waste load allocation and agreements with the State of Utah.
Since the 1960 session of the conference, Franklin Sugar Company
closed down, and other significant dischargers have installed
treatment facilities.

IDAHO WATER QUALITY STANDARDS FOR THE BEAR RIVER
According to Idaho's Water Quality Standards, the Bear and Cub
Rivers have been designated as primary contact recreational waters
(Class A). These are waters where the human body may come in direct
contact with the raw water to the point of complete submergence. The
raw water may be accidentally ingested and certain sensitive organs
such as eyes, ears, nose, etc. may be exposed to the water. These
waters may be used for swimming, water skiing, skin diving, support and
propagation of fish, aquatic and semi-aquatic life and other forms of
wildlife.
Worm Creek has been designated as secondary contact recreational
waters (Class (B). Class B waters are for uses in which the raw water
supply is suitable for support and propagation of fish and other
aquatic and semi-aquatic life, and other forms of wildlife. These
waters may be used for boating, wading, and other activities where
ingestion of the raw water is not probable.
The following Idaho Water Quality Standards apply to special
waterbodies of the Bear River Basin:
Bear Lake
1. Total Coliform concentrations were associated with a fecal
source(s) shall not exceed a geometric mean of 50/100 ml., nor shall
more than 20 percent of total samples during any 30 day period exceed
200/100 mg. (as determined by multiple-tube fermentation or membrane
filter procedures and based on not less than 5 samples for any 30 day
period).
-23-
-------
2. Fecal Coliform concentrations shall not exceed a geometric
mean of 10/100 ml., nor shall more than 10 percent of total samples
during any 30-day period exceed 20/100 ml.; or greater than 50/100 ml.
for any single sample. Coliform criteria for shoreline waters shall
conform with that of Class A2 waters. Shoreline waters shall be
defined as the first 100 feet of water surface as measured from the
shoreline.
Bear River and Cub River
1. Total coliform concentrations where associated with a fecal
source(s) shall not exceed a geometric mean of 240/100 ml., nor shall
more than 20 percent of total samples during any 30-day period exceed
1000/100 ml. (as determined by multiple-tube fermentation or membrane
filter procedures and based on not less than 5 samples for any 30-day
period).
2. Fecal coliform concentrations shall not exceed a geometric
mean of 50/100 ml., nor shall more than 10 percent of total samples
during any 30-day period exceed 200/100 ml.; or greater than 500/100 ml.
for any single sample.
Worm Creek Class B
1. Total coliform concentrations where associated with a fecal
source(s) shall not exceed a geometric mean of 1000/100 ml., nor shall
more than 20 percent of total samples during any 30-day period exceed
2400/100 ml. (as determined by multiple-tube fermentation or membrane
filter procedures and based on not less than 5 samples for any 30-day
period).
-24-
-------
2. Fecal Coliform concentrations shall not exceed a geometric
mean of 200/100 ml., nor shall more than 10 percent of total samples
during any 30-day period exceed 400/100 ml.; or greater than 800/100 ml.
for any single sample.
The following Idaho Water Quality Standards apply to the entire
Bear River Basin:
Bear Lake, Bear River, Cub River and Worm Creek
The dissolved oxygen D.O.) concentration not to be less than
6 mg/1 or 90 percent of saturation, whichever is greater.
1. The DO standard shall apply to all flowing waterways.
2. The DO standard shall apply to the waters of all natural lakes
and reservoirs except as excluded below:
a. In depths of water less than 100 feet in natural lakes or
reservoirs, the bottom 20 percent of water depth shall be
excluded from application of the DO standard. In water
depths greater than 100 feet, the bottom 20 feet of water
depth shall be excluded for application of the DO standard.
b. Waters below a thermocline in stratified lakes or impound-
ments shall be excluded from application of the DO standard.
c. No wastewaters shall be discharged and/or no activity shall
be conducted in waters excluded by a. and b. above, which
either alone or in combination with other wastewaters or
activities will cause the DO concentration in these waters to
be less than 4 mg/1.
-25-
-------
c. Notwithstanding exclusion of a. and b. above, the DO
standard shall always apply to the top two feet of any lake
or reservoir.
The hydrogen ion concentration (pH) values are not to be outside
the range of 6.5 to 9.0. The induced variations shall not be more than
0.5 pH units.
Any measurable increase when water temperature is 66 F or above,
or more than 2°F increase other than from natural causes when water
temperatures are 64°F or less (unless otherwise specified).
Any increase exceeding 0.5 F due to any single source, or 20 F
due to all sources combined.
For purposes of determining compliance, a "measurable increase"
means no more than 0.5^F rise in temperature of the receiving water
as measured immediately outside of an established mixing zone. Where
mixing zone boundaries have not been defined, cognizance will be given
to the opportunity for admixture of wastewater with the receiving
water.
The turbidity other than of natural origin shall not exceed 5
Jackson Turbidity Units (JTU). Whenever the receiving water is
greater than 5 JTU, due to conditions other than those caused by man,
then no discharge and/or activity either alone or in combination with
other wastewater or activity shall cause an increase of more than 5 JTU.
Water Quality Criteria (1)
Other W.Q. criteria are also of concern in the Bear River although
not defined in the water quality standards of the state. The following
are only recommended criteria based on research:
-26-
-------
1. Mercury
2. Cadmium
3. Chromium
4.
5.
Lead
Chlorine
.05 ug/1 aquatic life toxicity
10 ug/1 livestock water limit
.03 mg/1 (T. hardness
-------
WATER QUALITY TRENDS
The State of Idaho has been sampling the Bear River at five
stations each year on approximately a quarterly basis. Those stations
are:
1. At the Wyoming-Idaho State line R.M. 273.9
2. Near Montpelier downstream of the Bear Lake Outlet Canal
Confluence R.M. 219.3
3. At Soda Spring, Idaho (Above dam) R.M. 174.4
4. Near Grace, Idaho below Grace Power Plant R.M. 156.6
5. Near Preston, Idaho R.M. 97.3
Figures 1A through 11A (Appendix A) show plots of Dissolved
Oxygen (D.O.), D.O. saturation, alkalinity and orth-phosphorus
concentrations data collected from 1969 to the present time for these
stations. Basically, for the parameters shown there has been very
little change in water quality conditions in the Bear River in the
last six years neither in time nor over the length of the River.
Although standards were generally attained, water quality violations
for D.O. were documented at Montpelier, Soda Springs and Preston
stations over the six year period. Alkalinity, phosphorus and pH levels
which are high throughout the six year period throughout the river
system are indicative of high algal blooms condition which occur in
predominately agricultural areas. The ortho-phosphorus levels shown
on Figures 4A and 8A are considerably greater than the .025 mg/1 P04
which is considered a minimum requirement for an algal bloom.
Water quality of the Cub River and Worm Creek; like the Bear
River, has not changed appreciably over the last six years. Figures
-28-
-------
12A and 15A show the ambient monitoring data collected by the State
of Idaho on a quarterly basis over the period. All data suggests a
high level of algal activity. The high D.O.'s were obtained during the
daylight hours during the period when algae are undergoing photosynthesis
and, therefore, supersaturate the water with D.O. No D.O. data is
available during early morning or night when D.O. levels would be the
lowest. The pH levels on Cub River in 1973 exceeded the upper limit
of the Idaho Water Quality standards again indicative of high algal
activity.
Table IA (Appendix A) shows a comparison of the pre-enforcement
conference (1954-1955) data collected in Idaho with the data collected
since the enforcement conference. The post-enforcement data is a
compilation of State of Idaho ambient monitoring data and EPA intensive
survey data. Available data was selected for two periods to conform to
the winter and summer food processing seasons. Those periods were
November through December and July through September. The EPA intensive
survey was conducted during the summer food processing season only, since
the main winter industry cited during the enforcement conference,
Franklin County Sugar Company, closed shortly after the conference.
There is not ample data available either before or after the
enforcement conference to document changes conclusively, but the
following indications are noted:
1. NOV-DEC period
Bear River
1. There appears to be higher levels of 5-day Biochemical
-29-
-------
Oxygen Demand (BODS) in the river since the enforcement
conference although the D.O. levels don't reflect that
increase. The unexpected high D.O. levels are probably
due to high reareation rates typically found during
November and December.
2. Total coliform populations are apparently greater during
post enforcement period times than before. This difference
is not significant due to the analytical techniques used.
Cub River
1. Instream BODS levels are significantly less following the
enforcement conference than prior to it. This is due to
the treatment installed at Del Monte Cannery following the
conference.
2. JULY-SEPT. PERIOD
Bear River
1. Instream BODS levels are greater following the conference
than before. This increase is reflected in the lower D.O.
concentration reported on several occasions following the
conference and including the values from the EPA intensive
survey in 1974. This higher BODS and lower dissolved oxygen
levels in the river could be due to a greater amount of
algal activity in the river system resulting from
increased agricultural activity in the basin.
-30-
-------
2. Total coliform levels reported by Idaho appear to be
considerably greater than prior data showed; however,
total coliform data during a three day period shows the
level to be very low. No conclusions can be drawn from
this information.
Cub River
1. There appears to have been an improvement in the water
quality in the Cub River during this time of the year.
The BODS level reduction between the comparative periods is
greater than appears because the stream flow is small. The
meager post enforcement conference data indicates that the
D.O. level is higher and the bacteria levels are lower in
the reach below Del Monte Cannery. This is to be expected
since treatment facilities have been installed and the BOD
levels have dropped.

AUGUST 1974 SURVEY
SURVEY DESCRIPTION
The Bear River in Idaho cannot be adequately studied as one
continuous river because major river diversions, inflows, and im-
poundments are located throughout the river which alter the river
characteristics and make it function as nearly independent segments.
For the August 27 thru 29 Bear River survey, the river was
divided into the following four independent reaches:
1. Bear River between the Wyoming-Idaho border and Rainbow
Inlet to Mud Lake. R.M. 274.5 to R.M. 232.0
2. Bear River between the Bear Lake Outlet and Grace Dam
R.M. 220.5 to $.M. 164.0
3. Bear River between Grace Power Plant and Oneida Dam.
R.M. 157.0 to R.M. 126.0
4. Bear River between Oneida Dam and the Idaho-Utah border
R.M. 126.8 to R.M. 93.8
Mud Lake and the Idaho portions of Cub River and Worm Creek
were also analyzed separately since they function independently.
A reconnaissance trip was made to the basin by EPA personnel
for the purpose of locating sampling points, measuring flows, placing
macroinvertibrate samplers, and working out logistic problems. It
was decided to sample the river daily for three consecutive days,
the tributaries, drains and springs would be sampled only once since
these flows are relatively constant. The reach of river between Oneida
-32-
-------
Reservoir and the Utah-Idaho border had to be sampled early in the
morning to obtain a sample at constant flow. The reservoir is used
for power peaking and the flow fluctuates rapidly over the day. The
reservoir release, however, is held fairly constant overnight and is
not increased until about 8 or 9:00 each day. The sampling procedure
was to sample just below this darin at about 6:00 each morning and
work in a downstream direction completing the last station near the
stateline before the raising flow reached the downstream station. The
res Its of this study reach cannot be analyzed with the rest of the
river since the flows are considerably lower than the rest of the
river.
An automatic sampler was placed near the Idaho-Utah state line so
that diurnal fluctuations in river quality could be determined over
a 48 hour period. Samples were collected and analyzed at two hour
increments over the period for turbidity, specific conductance,
nutrients, and organic carbon.
Table IB (Appendix B) lists and the map on Figure 3 shows the
survey sample locations. Figure 4 is a map showing all survey flow
meausrement locations for the study area.
All river, tributary and spring samples were collected using
the following procedures:
1. Samples were collected using a Kemmer sampler or by sample
cubitainer.
2. Specific conductance, ph and temperature were analyzed
at the sample site immediately. Samples collected for shipment
-33-
-------
to the main EPA lab were preserved, tagged and iced on the
site.
3. Dissolved oxygen samples were fixed at the site, iced and
taken to the field lab in Preston for titration.
4. Samples for alkalinities and turbidity were taken to the
field lab for analysis.
Flows were obtained by one of the following methods: reading
river stage recorder charts that correspond to sample time then
determining flow using a rating curve; obtaining flows from a water
master or; measuring the flow using a gurley current meter.
Samples for pesticide analysis were collected in the water
column in one (1) gallon glass jars and capped with teflon lined lids.
The jars were kept in the dark and shipped to the Redmond, Washington
lab for analysis.
Benthic macroinvertebrate samples were collected using artificial
substrates of the rock-basket type. The substrates were exposed for an
eight week period (August through September 1974) at representative
sites on the Bear River. At the end of the eight week period, the
colonized substrates were removed and the macroinvertebrates were
scraped from the substrate into a jar containing a 70% ethanol
solution. The samples were then shipped to the Redmond Laboratory
where they were sorted, counted and identified by genus and species
where possible. This information was used to calculate a species
diversity index (DBAR) and species density.

portions of the Bear River were obtained by exposing artificial sub-
strates (glass microscope slides mounted in partially submerged wood
frames). The slides were removed from the frames after an exposure
period of eight weeks. The slides were frozen in dry ice and shipped
to the Redmond Laboratory for spectrophotometric analysis.
Bacteria samples were collected and analyzed as follows:
All samples were collected according to standard methods (2)
in sterile polyproplyene screw-cap bottles with aluminum foil hoods.
To each bottle 0.5 ml of a 10% solution of sodium thiosulfate was
added prior to sterilization.
Stations exhibiting a fecal coliform values greater than 150/100 ml
were sampled an additional time. Bacteriological analyses of these
samples were expanded to include Pseudomonas aeruginosa and
Staphylocoecus aureus.
Total coliforms, fecal coliforms and fecal streptococci were
determined using the MF technique in accordance with standard methods
(2), the medium selected for fecal streptococcus (Lancefield's Group D
Streptococcus) enumeration was KF streptococcus agar with 1% TTC added.
Quantatitive tests for S. aureus and P. aeruginosa were also
performed. The former organism was isolated by the MF procedure on
m-Staphylocoecus broth and confirmed by coagulase-testing and DNase
activity. P. aeruginosa was isolated on m-PA agar according to the
method of Levin (3). Verification of suspected colonies was accomplished
by observations of casein hydrolysis and fluorescent pyocyanin pigment
production of milk agar.
-37-
-------
Effluent samples from all significant wastewater sources were
collected concurrent to the receiving water sampling. Municipal and
Industrial samples were collected using automatic composite samplers
that were located in the discharge line. Samples were collected by
the automatic samplers on 15 minute intervals over a 24 hour period.
A grab sample was taken at the Del Monte Plant in Franklin, Idaho
since they have a lagoon treatment facility which characteristically
produces an effluent of uniform quality.
All samples were collected in 1 gallon polyethelene containers
and then split into individual containers for the various analyses
that were needed. Preservatives were added to the samples according
to standard EPA methods. Samples for BODS analysis were taken from
the 24 hour composites, iced and shipped to the EPA laboratory at
Redmond, Washington. Settleable solids analysis using the Imhoff Cone
method were run the same evening of sample collection.
The BODS samples were set up immediately upon arrival at the EPA
Redmond laboratory and all other samples were anlayzed according to
their perishable priority. All samples were preserved and analyzed
using standard EPA methods.

AUGUST 1974 INTENSIVE SURVEY RESULTS
Hydrology
Flow determinations during the survey were made by either 1-Reading
USGS or Utah Power Co. existing gages, 2-Actual flow measurement, 3-flow
determined by water master, and 4-flow estimation. Table lib shows the
actual values. The locations of the stations are shown on Figure 4.
The flow conditions existing at the time of the survey are discussed
separately in the following paragraphs for the Bear River, Cub River and
Mud Lake.
River Hydrology:
Figure IB is a stick diagram showing locations of the tributaries,
diversions and irrigation returns that were significant during the three
day survey period.
The curves on Figure 2B show the flow along the Bear River in Idaho
for the three day study period of August 27,28 and 29th. The points
on the figure represent instantaneous flow corresponding to sampling
times.
Flows from R.M. 233 to 220 are minimal (approximately 5 to 10 cfs.),
therefore, the river actually begins again downstream of the Bear Lake
outlet confluence with the Bear River R.M. 15.9. The flows again are
minimal below Grace Dam at about R.M. 167. The only flow in the reach
from R.M. 167 to R.M. 156 or about 11 miles is from spring water. River
flow fluctuates considerably below Oneida Reservoir due to varying
power demand; therefore, the flow shown in the figure from R.M. 130
-39-
-------
to the stateline is for a minimum release flow and cannot be compared
to the upstream flows.
The Bear River flow is supplemented by groundwater throughout
the entire river reach in Idaho with most occurring in the stretch
of river from Alexander Reservoir to the stateline in the form of
springs. Hot springs are abundant in the lower reach from approximately
R.M. 150 to the stateline.
Cub River Hydrology:
The majority of the flow is diverted at Cub Canal diversion
during the irrigation season. The Cub Canal diversion takes off at
approximately R.M. 20.9 on the Cub River. Flow in Cub River during the
August 1974 survey period, as shown in Figure 3B, at 40 cfs just down-
stream of the diversion. The river slows through agricultural land and
appears to lose substantial flow to ground or diversions until it
reaches Franklin, Idaho. Flow in the Cub River just upstream of
Franklin (R.M. 16.5) was measured at 7.8 cfs. The next point of
measurement was downstream of the Del Monte discharge at R.M. 15.1.
Flow at that point was 22.5 cfs. The source of this inflow between the
two flow measurement points is unknown. Worm Creek enters the Cub
River at approximately R.M. 7.9. During the survey period approximately
12 cfs was measured in Worm Creek leaving Idaho and presumably entering
the Cub River in Utah.
A "stick diagram" showing the inflows to and outflows from the
Cub River is shown on Figure 4B.
-40-
-------
Mud Lake Hydrology;
Mud Lake is located in the Bear Lake National Wildlife Refuge
which is directly north of Bear Lake. Mud Lake is supplied by the Bear
River via Rainbow Canal behind Stewart Dam. This water may be released
from the canal for storage in Mud Lake or released directly into the
Bear Lake outlet canal. The water from Mud Lake is diverted into Bear
Cake by a sluiceway at a pumping plant or by gates in a causeway at the
south end of Mud Lake if supplemented water for storage is needed in
Bear Lake. Bear Lake, as an offstream reservoir is operated by the
Utah Power and Light Company for power, downstream irrigation and
maintenance of favorable flow conditions in the Bear River.
Other inflow sources to Mud Lake are Bloomington Creek and small
irrigation return flows from the west as well as Crockett and Black
Otter canals from the east.
Figure 5B is a "stick diagram" of the flow condition that
existed during the August 27,28 and 29, 1974 survey period. Table IIIB
contains the inflows and outflows that occurred during the survey period.
During that period, approximately 900 cfs were flowing from Bear Lake
into the Bear Lake outlet canal which runs through Mud Lake. Comparing
the inflow and outflow, it appears that approximately 86 cfs are
entering Mud Lake through groundwater or unaccounted for passages.
This difference, however, is small and could partly be accounted for
by the variance in accuracy of the flow measurement.
-41-
-------
Point Source Dischargers
Table IVB shows the Organic and nutrient loadings in the basin,
while Tables Vb and VIb, show the point source data collected from
the main municipal and industrial dischargers in the Bear River Basin.
The data represented is for average values during the August survey
period and is based upon a 24 hour composite for all sources except
the Del Monte Corporation discharge which has a lagoon treatment system
and the Caribou Trout Farm which has a continue s discharge. Grab
samples were taken from these discharges.
All sewage treatment plants discharge into either the Bear River,
or its tributaries. The effects of these discharges upon the receiving
water are minimal for the most part; however, any noticeable effects
will be discussed in the following sections.
Monsanto Corporation discharges into Soda Creek which is
essentially an irrigation canal during the irrigation season. Very
little if any of their discharge enters the Bear River system during
the irrigation season; however, it is not known how much enters the
Bear River system during the remainder of the year. The discharge
sampling program for Monsanto corresponds with a compliance monitoring
evaluation which was completed concurrently. The compliance monitoring
evaluation report is included in the Appendix of this report.
Caribou Trout Farm utilizes spring water, supplemented by Little
Spring Creek water for their operational water supply. Their discharge
is into Little Spring Creek near its confluence with the Bear River
in the backwater of Alexander Reservoir.
-42-
-------
Del Monte Corporation discharges into the Cub River during food
processing season. The effect of this waste on the receiving water
will be discussed in the following sections.
Gem Valley Cheese is a small operation below Grace power plant.
Loadings could not be calculated because flow from the plant is inter-
mittent and could not be measured during the survey; however, discharge
constituent concentrations were determined and are included in the
tables. A compliance evaluation was made at this plant also but no
report was prepared due to the small size of the operation.
Water Quality Standards Violations
The August 27,28 and 29 intensive survey data shows that although
very few water quality standards were violated technically, values
were either very close to limits or not enough samples were taken to
support the numerical criteria of the standards.
Coliform Bacteria
Only three samples at each main river station were collected
during each day, therefore, not enough samples were collected to
apply the Bear River water quality standards. However, there is no
reason to believe that total bacteria levels would not be violated if
enough samples were taken. Figure 6B shows the bacteria results in
the Bear River and the water quality standard levels for both total
and Fecal coliforms.
Fecal coliform levels found on the survey exceed the Class A
-43-
-------
single sample criteria of 500/100 ml. for the Bear River tributaries
of Montpelier Creek, Stauffer Creek, a spring near Preston, and a
creek north of West Pump Canal. These are tributaries to the Bear
River and, therefore, are subject to the same standards. Class B
waters of Worm Creek had single sample violations (800/100 ml.) at
Worm Creek below the Preston STP and again near Franklin, Idaho.
Bacteria levels for these tributaries, as well as other tributaries
in the basin are shown on Table VIIB.
Dissolved Oxygen
All samples for dissolved oxygen analysis were taken during the
daylight hours, therefore, they probably would not reflect the lowest
values that would occur in the river system. However, one value is at
the lower limit of acceptable concentration. Diurnal studies would
have undoubtedly shown violations of Water Quality Standards for
dissolved oxygen concentration.
Figure 7B shows actual daytime dissolved oxygen concentrations as
well as percent saturation values by river mile for the mains tern of the
Bear River. The 6 mg/1 concentration standard is not violated, although
the limit is approached in the Montpelier area. However, the 90 percent
water quality criteria is violated at several points along the Bear
River. The most notable area is in the Oneida Reservoir area. The
90% criteria is violated from approximately R.M. 140 in Oneida
Reservoir to the Utah-Idaho border. Greater than 100 percent D.O.
saturations are indicative of photosynthesis by algae and occurs
-44-
-------
during the daylight hours. These same algae respire at night
driving the D.O. levels below the 100% saturation level. Percent
saturation levels of 120 to 130 percent normally means night time levels
would be much lower than 90% and, therefore, concentrations would be below
the 6 mg/1 levels.
Based upon the above discussion, the magnitude of dissolved
oxygen violations would probably be greater and cover a greater portion
of the river if samples were collected during the early morning hours.
Turbidity
Idaho Water Quality standards state that a 5 JTU increase above
background level of turbidity is a violation of Idaho water quality
standards. The JTU value of Bear River water entering Idaho from
Wyoming is around 10 JTU, therefore, any change of 5 JTU's other
than natural would be a violation. Irrigation downstream from the
Idaho-Wyoming border changes the turbidity level, shown in Figure 8B,
drastically, resulting in Water Quality Standards violations from about
the Bear Lake diversion (R.M. 242.7) to Alexander Dam (R.M. 169.4).
Alexander Reservoir apparently acts as a settling basin, thereby re-
ducing the turbidity levels again to the initial levels. Idaho water
quality standards for turbidity in the Cub River were violated during
the August EPA survey. Turbidity levels of the Cub River (Figure 9B)
increased from less than 3 JTU upstream of the Del Monte discharge to
about 11 JTU below the discharge, constituting an increase greater
than 5 JTU due to man's activity.
-45-
-------
pH levels in the Bear River (Figure 10B) and Cub River (Figure 11B)
did not violate water quality standards during the survey period;
however, the levels are near the upper levels of the standard.
Cause and Effect Discussion
Bear River
Recreation
The health of a stream can be determined non-technically by
looking at the actual recreational use of that stream. Figures 12B
and 13B show the areas in the Bear River that successful fishing has
been taking place as well as the numbers of fish that have been caught.
(4) Limited fishing takes place between the Bear Lake outlet and Oneida
Reservoir; however, the best fishing areas occur in the stretch of
river from Alexander Dam to Grace Dam and in the area of Grace Dam to
Grace Powerhouse where only a minimal flow due to river discharge
occurs. The River is diverted at Grace Dam through a pipeline system
to Grace Dam and the only flow in that reach is due to groundwater
inflow.
Invertebrate Population
The benthic macroinvertebrate community also indicates the health
of a stream. Unpolluted streams for the most part contain a biologic
community with a high species diversity. Polluted waters support a
community of low species diversity.
The species composition of the benthic macroinvertebrate community
-46-
-------
in the Bear River is dominated by those organisms which are
facultative in their tolerance to organic pollution. The diversity
index calculations (See Figure 14B) further substantiate this
contention by indicating moderately polluted water throughout the
Bear River study reach. Diversity index of 3 or above is indicative
of a healthy community. (5)
Heavy Metals
Figures 15B to 17B depict heavy meatls concentrations throughout
the Bear River system. Toxicity levels shown on the curves are from
the "1972 Water Quality Criteria" (1). Hardness as CaC03 (Figure 18B)
is also included here since toxicity is related to the water's hardness.
The heavy metals curves are dashed denoting that samples were taken
only at selected points, not at all stations.
Bear River water is hard entering Idaho, it's CaC03 concentration
is about 250 mg/1. Water from Bear Lake outlet canal that makes up
the Bear River water just downstream of Montpelier has a hardness
level on the order of 300 mg/1 and the level gradually rises in a
downstream direction due to groundwater and surface water inflow
(See Table VIIIB for chemical constituents of these inflows). Figure
15B depicts the total mercury concentrations in the Bear River. The
curve shows that the levels of these constituents recommended safe
for aquatic life are exceeded throughout the entire Idaho reach of
the river. The levels decrease considerably in Alexander Reservoir
indicating that the Reservoir is concentrating Hg in it's bottom
muds. Zinc and Cadmium levels are low in the basin (See Figures 16B
and 17B).
-47-
-------
Algal Bloom Potential
River mile graphs shown on Figures 19B through 22B represent the
potential of the Bear River to support massive algal blooms. Phosphorus
concentrations (Figure 19B) during the 3 day EPA survey exceeded the
.05 mg/1 (6) level considered minimum needed for algal blooms. Total
phosphorus levels exceed this level for the entire length of the
river while nitrate-nitrogen (Figure 20B), another required nutrient,
never exceeded its 0.3 mg/1 (6) level. However, blue-green algae have
the ability to fix nitrogen from the atmosphere.
High total alkalinity (Figure 21B) and pH (Figure 10B) values
support the potential for algal blooms. Total alkalinity values like
hardness discussed earlier constantly increase through the river system,
and the pH levels are near 8 most of the time indicating that
bicarbonate alkalinity exists, thereby indirectly furnishing carbon
dioxide for plant growth.
Periphyton samplers were placed at several locations on the river
for the purpose of collecting samples for chlorophyll a_ analysis;
however, only four samplers were recovered. Chlorophyll _a results
(Figure 22B) from these samples show that chlorophyll a^ levels are
below the 10 mg/wr level which is considered a eutrophic threshold
(7). Chlorophyll level at one station below Grace Powerhouse was at 5.5
mg/rn^ which shows that the water was in a mesotrophic condition in
this area. Oneida Reservoir was observed to have heavy algal growth
occurring during the survey. The low chlorophyll value near Preston
cannot be explained by the survey results. Even though phosphorus
-48-
-------
levels are low in that area during low-flow, the diurnal fluctuation
of phosphorus concentrations (Figure 23B) appear to be directly related
to flow and greatly exceed algal productive levels. Another possibility
is that during the low flow period, debris floating down the river
catches on the samplers, thereby limiting sunlight.
Dissolved oxygen concentrations and percent saturation values are
shown on Figure 7B. These samples were collected during the day and,
therefore, reflect the photosynthesis produced dissolved oxygen by
algae in these areas where productivity is the greatest. Saturation
values reach 120 to 130 percent between Soda Springs and Oneida Reservoir.
Saturation values greater than 100% are indicative of photosynthesis.
Nutrients
Figures 24B and 25B show the relative total phosphorus and total
nitrogen nutrient loading to the Bear River in terms of ///day as well
as loadings from the sources. The survey results show that in the
upper rivers considerable phosphorus has been picked up in the Mud
Lake area (the relative contribution in the Mud Lake reach will be
discussed in a later section).
Other measured sources of phosphorus which effect the Bear River
are Georgetown and Soda Creeks. Both tributaries flow through
populated and agricultural areas; however, samples of groundwater in the
Georgetown area (See table VIIIB) showed total phosphorus concentrations
of about 0.1 mg/1 and most of Georgetown Creek water is composed of
groundwater. Soda Creek is high in total phosphorus mostly resulting
from irrigation water reuse in the Soda Springs area. Phosphorus
-49-
-------
below Grace Power plant is due to mainly groundwater. Springs
sampled between Soda Springs and Oneida Reservoirs (Table VIIIB) show
total phosphorus concentrations of .17 mg/1.
o
Major nitrate nitrogen (NO -N) loadings in the River Basin are
from Georgetown, Big Spring and Soda Spring creeks in the Reach
between Mud Lake and Alexander Reservoirs. Again springs sampled in
this reach show groundwater (approx. 3.4 mg/1) the main reason. In
the reach between Alexander and Oneida Reservoirs Whiskey and Trout
Creeks have measurable contributions; however, groundwater is the
main reason for the high concentrations. Groundwater NO-^-N
concentrations in this reach range between .09 mg/1 for hot springs
to 3.0 mg/1 for cold springs. Diurnal NO-^-N measurements taken at
R.M. 104.3 on the Bear River near Preston and shown on Figure 26B
show that Nitrogen concentrations vary from 0.1 mg/1 at high flow to
0.17 mg/1 at low flow. This data shows that groundwater is a main
contribution to nitrate nitrogen in this portion of the River.
Solids
Figure 27B shows the total, dissolved and volatile solids in
the main stem of the Bear River.
There is a substantial increase in total solids concentrations
in the Bear River from the Wyoming-Idaho border to the Utah-Idaho
border. The increase is fairly constant throughout the study reach.
The majority of the solids is in the form of dissolved solids and
approximately 20 to 30% of the total solids are of organic nature.
Suspended solids concentrations (Figure 28B) are minor compared to
-50-
-------
the other forms of solids. However, suspended solids levels coincide
with turbidity levels (Figure 8B) and affect the fishing to a greater
extent than other forms of solids. The lower suspended solids and
turbidity levels coincide directly with the highest fish catch levels
in the Bear River (Figure 12B). Survey data (See Appendix C) show
that spring water turbidity levels are minimal and since spring water
makes up part of the flow in the Bear River below Alexander Reservoir,
the ground water dilution plays an important role in this stretch.
High dissolved solids are representative of groundwater inflow and
agricultural runoff. Specific conductance has a relationship to Total
Dissolved solids. When the total dissolved solids level is less than
2000 mg/1, the T.D.S. level is approximately .6 to .7 times the specific
conductance level. Figure 29B shows the conductivity levels in the
Bear River. The conductivity-T.D.S. relationship described above holds
true for the river. Table VIIIB shows the specific conductance for
the tributaries and groundwater inflows for the various reaches of the
Bear River. The data shows that the first major increase in con-
ductivity occurs downstream of the Bear Lake outlet canal. The canal
water itself measures nearly 700 umho/cm. Major inflows of ions occur
in the Soda Springs area and downstream via Big Springs, Soda and
Whiskey creeks as well as all hot and cold springs flowing into the
River. The spring inflow conductivity range from 900 to 1400 umho/Cm.
Bacteria
Figure 6B shows river mile plots of total and fecal coliform
bacteria along with fecal streptococci (strep) for the Bear River
-51-
-------
and its tributaries. Figure 30B shows the relationship ratio of
fecal coliform to fecal streptococci bacteria. Large fecal strep
densities represent bacteria from agricultural sources and low fecal
strep densities associated with higher fecal coliform densities represent
evidence of domestic sources of bacteria. A mean FC/FS ratio of 2.0
from samples strongly suggests bacteria from a domestic source while
a ratio of 0.7 or less strongly suggests animal sources of bacteria.
A ratio between 1.0 and 2.0 indicates an uncertain source of bacteria
contamination. However, this does not mean bacteria from domestic
waste is not present only that there is a predominance of animal waste.
The complete bacteria survey data is included in Appendix B.
Downstream from the Wyoming border to Montpelier all three
bacterial indices increased progressively reflecting a loading due to
increased agricultural use. From Montpelier to Soda Springs all
bacterial counts were quite variable with no discernable pattern.
However, from Soda Springs to Preston all three indicators reflected
bacterial loading due to a combination of agricultural runoff and/or
domestic use.
The FC/FS ratio for the Bear River were all lower than the .7
value indicating a predominance of bacteria of farm animal origin.
However, high FC/FS ratio were detected on Ovid, Montpelier and Soda
Springs Creeks which suggest possible bacterial contamination from
human sources.
High bacterial levels were found in a spring located south of
Oneida Rd. West of Preston (Station 153587). Total fecal and fecal
-52-
-------
strep, populations were 10,000, 2,700 and 7,800 per 100 ml.
respectively indicating contamination of the spring probably from a
livestock source since the FC/FS ratio was about 0.4.
Table IXB summarizes the bacterial pathogen data. Coagulase-
positive _S_. aureus was found in 8 out of 13 (62%) samples examined.
High numbers of this organism were found in Montpelier Creek; Bear
River, Trout Creek, Williams Creek near Thatcher; Bear River near
Fairview and at Upper Canal near Fairview. The presence of these
pathogen in water suggests pollution from a human rather than animal
source.
Pesticides
Table XB shows the results of pesticide analysis at selected
stations in the Bear River Basin. Many other chlorinated hydrocarbon
and organophosphate parameters were analyzed; however, only those shown
on the table were above the analytical threshold.
Lindane (BHC) levels exceeding 0.005 ug/1 were equalled or exceeded
at all but three locations sampled in the basin. The recommended
toxic level for BHC is considered to be .005 ug/1 according to Water
Quality criteria. (1) Detectable levels of DDD, DDE, DDT and Lindane
were found only in the reach above the confluence of the Bear River
and the Bear Lake outlet. The levels of these parameters were below
detection limits in the Bear Lake outlet which makes up the majority
of flow below that point and, therefore, has an overwhelming influence
on the character of the river flow during this time of year. It
appears that most of the conservative pesticides are entering Idaho
-53-
-------
from Wyoming. The toxic levels for DDD, DDE and DDT are considered
to be approximately 0.05 ug/1.
Mud Lake
Table VIIIB shows the concentration of various constituents of
the inflows and outflows to Mud Lake and Table XIB contains nutrient,
organics and bacteria loading in the Mud Lake area. It appears that
twice as much phosphorus is leaving the Mud Lake area as entering. The
same ratio of suspended solids is leaving Mud Lake also. The reason
for this transport out of the area was probably the high discharge
(900 cfs) from Bear Lake scouring the sediments in Mud Lake that were
deposited during a lower flow portion of year. Since phosphorus
absorbs into soil particles, the phosphorus levels are also transported
out of Mud Lake; therefore, during the survey period, Mud Lake was a
source of suspended solids and phosphorus.
Nitrate nitrogen and total organic carbon (TOG) were reduced
through Mud Lake; therefore, Mud Lake is functioning as a sink for
these constituents.
Drainage from the Paris, Idaho septic tanks is main contributor
of total fecal bacteria to the area; however, the high flow down the
Bear Lake outlet canal dilutes the small amount of concentrated
waste so that the bacterial levels entering the Bear River are less
than 100/100 ml. A new treatment plant for Paris was under con-
struction during the survey period; therefore, the high bacteria levels
should be drastically reduced in the near future.
-54-
-------
Cub River
The Cub River was sampled at three locations along a six mile
reach. The three stations were at the Cub Canal diversion dam
(R.M. 20.9), at R.M. 16.5 just upstream of the community of Franklin,
Idaho and at R.M. 15.1 just below Franklin and the Del Monte discharge.
Results of the study are shown on Figures 31B through 36B and
Table XIIB.
This table shows the nutrient loadings in the Cub River. Total
phosphorus, nitrate and ammonia loadings have been reduced between
R.M. 20.9 and 16.5. Water use for agricultural purpose may be the
reason. The increase in loadings between R.M. 16.5 and 15.1 cannot be
explained by the discharge from Del Monte alone. In the 1.4 mile
reach the Cub River receives approximately 12.5 CFS flow, 18.5 Ig/day
of phosphorus, 30 Ib/day N03-N, and 57.5 Ig/day of NH3-N which is
unaccounted for. This area should be investigated further for additional
waste sources.
Bacterial densities on the Cub River as well as the FC/FS ratio
for the study reach are given on Table XIIB.
Del Monte discharges a high level of bacteria into the Cub River;
however, the samples taken approximately 1/2 mile downstream of the
discharge do not reflect the high densities. The dilution effect
of the additional flow in that reach and the die-off could help
explain this.

Cattle observed watering in the Cub River between R.M. 20.9 to 16.5
are probably the reason for the high fecal strep densities of 1600/100
ml. sampled at the lower station.
FC/FS ratios shown on the table strongly indicate bacterial
contamination caused by animals.
There is another discharge between the Del Monte discharge and
the downstream sample station. It appears the discharge is irrigation
return flow; however, access to this area is difficult and could not
be sampled. This could be the reason for the discrepancy.
Worm Creek
Samples were taken from Worm Creek at locations just above the
Preston sewage treatment plant outfall (R.M. 9.9) and approximately
0.8 miles downstream of the outfall. Twenty-four hour composite
samples were also taken from the Preston STP outfall concurrently as
part of the point source sampling program. Table XIIIB shows the
sample results.
The general quality of Worm Creek has not deteriorated much as
the result of the Preston sewage treatment plant. In fact, in some respects
the discharge has improved the water of Worm Creek.
However, during the August 1974 survey high levels of bacteria
were observed in the discharge of Preston STP as well as Worm Creek
Immediately downstream and as far as 0.8 miles downstream from the
outfall. Fecal counts as shown on the table, increase from 90/100 ml.
upstream of the outfall to a high of 50,000/100 ml. just downstream

-------
and are still high (870/100 ml.) at the downstream sample point.
Pathogenic bacteria E. aeruginosa (40/100 ml) and S. aureus (200/100 ml.)
were detected in Worm Creek below the Preston sewage treatment plant.
Although the numbers of these pathogens are not extremely high, their
presence is indicative of poor disenfection practices.
Fecal bacteria levels from Preston STP were on the order of
100/100 ml. which does not account for the high level in the stream;
however, STP samples were taken August 28 and Worm Creek samples were
taken on August 29th which could account for the bacteria differences.
During this period the operator at Preston STP was having trouble with
the chlorination equipment.

For the purposes of this subsection, the c'.iiT.y average discharge,
except for flow and temperature, is the total discharge by weight during
a calendar month divided by the number of days in the month that the
production or commercial facility was operating. For flow, temperature,
and those parameters sampled at a frequency other-than daily,jthe daily
average is the arithmetic mean of all samples collected during-a calendar
month.
.'For the purposes of this subsection, the daily maximum discharge,
except for flow and temperature, means the total discharge by weight
during any calendar day.
b. The pH shall not be less than 6.5 nor greater than 9.0.
The pH shall be monitored daily by analyzing a grab sample.
c. The plant's intake well water shall be monitored weekly
for total phosphorous (as P) by taking samples from the individual wells
when operating and compositing according to' their actual corresponding
usage from each, well during the week.
PROCESS DESCRIPTION
The following information is taken from a source test report
(72-MM-27) for the Mbns'r ato Company.
Elemental phosphorus is-produced from phosphate rock by reduction
in an electric arc furnace. Typical ores contain 10-13% phosphorus-so
C-2
-------
that about 10 tons of rode must be processed per ton of phosphorus prodir
Considerable quantities of coke, silica, and recycled materials are fed r
the furnaces with the beneficiated ore.
Prior to being fed to tne furnr.ce, the rock is agglomerated and heat
hardened in a kiln. The partially fused product is cooled and crushed tc
a specified siza before beinj fed to the furnace as- shown in Figure 1.
Phosphate feed is carefully proportioned with sili' a and coke before-
being transferred to feed bins directly above the furnace. The feed mixL
then moves by gravity from the bins down into the furnace as the furnace
feed is consumed.
The reaction within the furnace is approximated by the following
equation:
2 Ca3 (P04)2 + 10 C + 6 Sio2. (2300-27.00QF) ^ + 10 co + 6 CaSio3 .
f
Elemental phosphorous and carbon monoxide leave the furnace as gases
Dust is removed.'from the stream by an electrostatic precipitator and the
phosphorous vapor i-s later condensed out in direct-contact water condense
W.iste CO gas" is used as a' fuel in the kiln operation.
The molten process by-products and some coke must be periodically
removed from the' furnace by tapping. This molten material separates into
two layers inside the furnace. The lighter top layer is a, slag froia th.:
ore material. This slag has no economic value except as an aggregate. I'
is tapped alternately .from two tapholes at 15-minute intervals'. The slag
runs out into water-filled pits behind the furnace building.
Th ' heavier bottom layer is about twice the density of the slag, am'
islargely a phosphorous-iron mixture known as ferrophos. Thi~s metal by-
product is tapped from the furnace twice each day. The ferrophos is poui
into chills and then shipped to a nearby plant for vanadium recovery.
SELF MONITORING PROCEDURES
One outfall is used by the Company for discharge of cooling waters.
At the time of the survey all process waste water was being discharged to
non-overflow lagoons.
OUTFALL gOOl
Flow s measured continuously at this outfall by a Parshall flume in
the outfall line. Flow rate is recorded on a strip chart. A composite
sample is obtained daily.
C-3
-------
SURVEY DESCRIPTION
Monsanto's outfall was monitored for one day utiliz-lnj; automatic
sampling equipment. Samples were obtained at the; same location of compai<
installed monitoring devices. Samples obtained by the ISCO's were tiir.e
composited and split with Monsanto.
Although flow proportioning of the composite was not attempted, it
is believed that a representative sample of the effluent was obtain^1..
Flow on outfall #001 was observed to ba quite stable during the saiiiplln-
period. Due to the relatively stable ope-ation of the mill processes, fit
proportioning was deemed unnecessary.
Samples obtained by the ISCO were ke;>t cold during tho sampling
process by packing ice into the center section. The company sampling
device does not provide for refrigeration of the s"anple.
Sampling was initiated on Tuesday afternoon. The ISCO automatic
sampler was set for a one hour sampling frequency. A 2'i-hour composite-
sample was obtained.on Wednesday afternoon.
RESULTS
Table 1 presents the analytical results of tha cample; obtained'
during the survey. Based upon these results the Company was well within
their daily maximum effluent limitation for flow, total phospho'rous,
suspended solids, fluoride .and pH. An apparent violation occurred for
temperature.
