INTRODUCTION
This report on the quality of the waters of the Jordan River Basin
is based on information obtained during the June and August 1972
field investigations conducted by personnel of Region VIII, Environ-
mental Protection Agency.
The Utah Lake-Jordan River Basin has been one of the areas designated
by the Environmental Protection Agency as a Priority Basin; i.e., EPA
Region VIII is devoting the highest priority to a concentration of
resources in these basins to obtain water quality goals at the earliest
possible date. Thus, the priority basins receive first attention in
the allocation of regional resources. In addition, Utah Lake is listed
as a target area in EPA’s National Eutrophication Control Program.
In implementing the Priority Basin Concept, Region VIII in cooperation
with the State of Utah has conducted several studies in the Jordan
River Basin in an effort to assist the State in the gathering of per-
tinent water quality information. Through meetings and discussions
with the State and other concerned individuals and organizations, it
was determined that there existed certain areas that would benefit
from field work conducted by EPA.
The first of the studies in the Basin consisted of a short-term,
intensive water quality study of Emigration Canyon conducted during
the week of June 19—25, 1972. Also included in this study was a
limited nutrient investigation of the Jordan River in the vicinity
of a proposed impoundment on the river.
A second intensive effort during the period August 13-26, 1972, involved
the entire length of the Jordan River from Utah Lake to the Great Salt
Lake, and was focused on water quality and biological activity in the
river. The study was conducted to supplement previous data obtained by
the Utah Water Pollution Committee and the Utah Department of Fish and
Game in their program of pollution abatement and control, and river use
classification.
All sampling locations used in these investigations were developed in
conjunction with State needs and consisted of (1) stations presently
being sampled by the State, (2) newly established stations developed
to provide more detailed information in certain areas, and (3) sampling
sites where historic data was available within the study areas but not
included in the present State sampling program.
AREA
The Utah Lake-Jordan River Basin is a semi-arid interior drainage basin
located entirely within the State of Utah. Utah Lake, which averages
about 8 feet in depth, is located in the center of the Utah Valley
which is bounded on the east by the Wasatch Mountains and on the west
by the Lake Mountains.
—l —

-------
The Jordan River originates at Utah Lake and leaves the lake in a
northerly direction at an elevation of approximately 4,488 feet, and
flows approximately 55 miles northward to enter the Great Salt Lake
at an elevation of 4,203 feet. As the gradient of 5.2 feet per mile
indicates, a river of this type would tend to be slow and meandering
with few riffles. It would be subject to silting and quite vulnerable
to organic pollution due to its low capacity for natural reaeration.
At a point approximately 10 miles downstream from Utah Lake (at the Jordan
Narrows), flow in the Jordon River is affected by the first of several
diversion dams constructed for irrigation purposes. The average flow at this
location is approximately 350 cfs, ranging from about 1,400 cfs during the
spring run-off to 0 cfs when the irrigation gates are opened. Downstream
from the Diversion Dam at the Narrows, the river’s flow is augmented by
numerous springs, irrigation return flows, waste water treatment plant
effluents and about a dozen tributary streams (Figure 1). The most
significant of these treatment plants and tributaries to the Jordan River
are listed in Tables 1 and 2.
RESULTS OF STUDY
EMIGRATION CANYON
Based on meetings held between representatives of the State of Utah,
the firm of Templeton, Linke, and Alsup, the City and County of Salt
Lake, and the Environmental Protection Agency, EPA Region VIII personnel
conducted a short-term water quality investigation of certain elements
of the Utah Lake-Jordan River Basin during the period June 19—25, 1972.
The study, intended to provide baseline information, covered the elements
of: (1) bacteriological quality of Emigration Canyon (Creek), and (2)
nutrient concentrations in the area of the proposed impoundment of the
Jordan River. The results of all physical, chemical, and microbiological
determinations are tabulated in Appendix Table A-2.
Though some members of the coliform group are distributed widely in nature,
coliform bacteria are always present in excretions from the intestinal
tract of man and other warm-blooded animals. The absence of coliform
bacteria, therefore, is evidence of a bacteriologically safe water. The
presence of fecal coliform bacteria in the water environment is proof of
fecal contamination and an indication of hazardous pollution.
The microbiological investigation of Emigration Canyon was considered
necssary due to the lack of a common wastewater collection and treatment
systemalong the cnayon. Individual wastewater systems (cesspools, septic
tanks, etc.) discharge in the vicinity of or directly into the creek that
winds its way through the canyon.
Ten sampling locations were established along the creek from the vicinity
of the headwaters to its confluence with the Jordan River near 13th South
Street in Salt Lake City (Figure 2 and Table A-l). Daily grab samples
were obtained at all established stations with twenty-four-hour (round-
the-clock) samples obtained at two stations, EC-9 and EC-lO.

Results of the grab samples indicated that low total and fecal coli-
form densities existed in the headwaters of the creek. At station EC-l,
the mean total and fecal densities were 20/100 ml and 6/100 ml, respectively
(Figure 3). Moving downstream, both the total and fecal mean densities
steadily increased, reaching maximums at station EC-9 (IC 2413/100 ml and
FC 623/100 ml over the 5 routine sampling days), the point where the creek
enters the 13th South Storm drain. This increase is indicative of the
effects of discharges along the stream’s course.
The construction of the storm drain outfall is such that is is not possible
to sample the outlet of the storm drain (creek) before it becomes partially
mixed with Jordan River water. Station EC-lO, the outlet of the storm
drain, therefore, indicates the density of coliform in the creek mixed with
the Jordan River. At this location, mean densities (over the 5 routine
sampling days) of 1052/100 ml total coliform and 177/100 ml fecal coliform
occurred.
At the station located in the Jordan River approximately 50 yards upstream
from the confluence with the 13th South storm drain, mean total and fecal
coliform densities of 64,000/100 ml and 3200/100 ml respectively, occurred.
These values in the Jordan River indicate that the impact on the river from
waters entering from the Emigration Canyon area was slight at the time of
this investigation.
Water quality classifications applicable to all waters in the Utah Lake-
Jordan River Basin call for total coliform densities not to exceed
5000/100 ml. Although the daily grab samples did not indicate values
in excess of this criteria (Figure 3), the round-the-clock samples did
indicate that at times during thedaytotal coliform densities increased
to levels which exceeded this criteria at stations EC-9 and EC-lO
(Figures 4 and 5). This is of particular significance in that the sport
of “tubing” - riding an innertube down the creek - was observed in the
area of stations EC-8 and EC-9. In this reach between these two stations
the creek is enclosed for some distance in a large concrete pipe. The
“sport” calls for the navigation by innertube through this pipe. The
high coliform densities at these locations, therefore, indicate a probable
health hazard to those indulging in this “sport.”
Organic matter contained in municipal and many industrial wastes, when
biochemically degraded, exerts an oxygen demand on the waters receiving
such wastes, resulting in a reduction of the dissolved oxygen resources
of the waters. High concentrations of such oxygen-demanding wastes can
cause excessive dissolved oxygen depletion, resulting in a reduction of
desirable aquatic life, including fish, and create unpleasant odors.
Dissolved oxygen requirements applicable to all waters in the Utah Lake-
Jordan River Basin call for a dissolved oxygen concentration of 5.5 mg/l
to be maintained for a warm water fishery and that a concentration of
6.0 mg/l be maintained for a cold water fishery. All waters of the basin
are classified by the State as a cold water fishery with the exception of
Utah Lake and the Jordan River from Utah Lake downstream to the Utah County
Li ne.

Dissolved oxygen determinations made during this study indicated that
the DO was fairly uniform over the reach from the headwaters (EC-l)
to station EC-9 (8.9 mg/i to 8.3 mg/i). The DO then decreased from
8.3 mg/i to 7.5 mg/i through the storm drain to the outlet to the
Jordan River (Figure 6).
The results of the nutrient Investigation in the vicinity of the pro-
posed impoundment of the Jordan River are discussed later in this
report.
JORDAN RIVER
As a result of additional meetings held between representatives of the
State of Utah, the consulting firm of Templeton, Linke, and Alsup, and
the Environmental Protection Agency, and based on the findings of the
field study conducted by the EPA In June, EPA Region VIII personnel
conducted an intensive short—term water quality investigation of certain
elements of the Jordan River Basin during August 1972. This study
covered the elements of: (1) bacteriological quality of the Jordan
RIver, (2) dissolved oxygen concentrations in the Jordan River, (3)
nutrient impact of irrigation return flow on selected tributaries and
the Jordan River, and (4) aquatic biology of the Jordan River. The
results of all physical, chemical, and microbiological determinations
are tabulated in Appendix Table A—3.
Water Quality
Microbiology
The microbiological examination of the Jordan River was initiated
to obtain information on short-term coliform concentrations,
through a short-term Intensive survey, for correlation with the
long-term measurements of the State of Utah.
Eighteen sampling stations were established on the Jordan River
(Figure 7) for this study. Another five sampling stations were
established on major tributaries to the Jordan. Sampling at
these stations was on a daily grab sample basis for a period of
nine days.
These stations were also used for all other water quality measure-
ments.
An additional round-the-clock study was undertaken during which
samples were collected throughout a 24-hour period to document
any changes that might occur during this time period. Two
routine Jordan River stations were included as part of this study.
These were JR-2 and JR-17, the Jordan River at Fairfield Road and
at Cudahy Lane, respectively. Three aqditional stations in the
vicinity of the Utah State Prison were also included.

Examination of the results of the daily grab samples indicated that
the waters leaving Utah Lake (JR-i, Saratoga Springs Rd.) and form-
ing the Jordan River, had a mean total and fecal coliform density
of 1180 and 70/100 m1, respectively (Figure 8). Over the 13-mile
reach of the river from JR-l to JR-4 (Bluffdale Rd.), the total
coliform concentration decreased and remained at a low level with
a range of mean densities between 350-575/100 ml. From Bluffdale
Rd. (JR-4) on downstream, the total coliform densities start to
increase from various sources, including irrigation return flows,
waste water treatment plant discharges, storm drains, and unknown
sources, to reach a peak mean concentration of 52,470/100 ml at
the station at 3rd South St. (JR—15).
From 3300 South St. (JR-13) downstream to the mouth of the Jordan
River, the mean densities at all stations in this reach exceeded
the 500/100 ml criteria for all waters of the Basin. From 7800
South St. (JR-9) downstream to the mouth, individual grab samples
indicated values in excess of this criteria.
The results of the round—the-clock sampling at Fairfield Rd. (JR-2)
and Cudahy Lane (JR—17) are shown graphically in Figures 9 and 10.
Chemi stry
The average dissolved oxygen values in the Jordan River equalled
or exceeded the DO reguirements from the station near Utah Lake
downstream to and including the station at 3300 South St. (JR—13).
From the station at 2100 South St. (JR-14) downstream to the mouth
of the river, the average dissolved oxygen values decreased steadily
and did not meet the cold water fishery DO requirement. At the
Cudahy Lane station (JR-17), the average DO was 3.7 mg/i (Figure 11).
During the June 1972 study, grab samples taken at selected stations
on the Jordan River (Table A-i) indicated that there might be photo-
synthetic activity taking place since dissolved oxygen concentrations
as high as 19 mg/i were measured (12600 South St., JR—5). To docu-
ment any diurnal differences in DO concentrations in the Jordan
River, two stations (Fairfield Rd., JR-2 and Cudahy Lane, JR-17) were
sampled on a round-the-clock basis.
The results of the round-the-clock sampling program indicated that
at Fairfield Rd. (JR-2), a significant dissolved oxygen change
occurred over a day’s time interval (Figure 12). DO concentrations
at this station varied over a range of 7 to 12 mg/i throughout a
24-hour period, reaching a peak concentration around 10:00 p.m.,
and a minimum concentration around 8:00 a.m. No significant diurnal
differences in the DO concentrations at the station at Cudahy Lane
(JR-17) were indicated (Figure 13).
The two most significant nutrients influencing biotic production
and nuisance aquatic plant growths are phosphorus and nitrogen.

factors such as velocity, turbidity, etc., are not limiting, the
number of algal cells increase, leading to such nuisance condi-
tions as surface scums and odors, Several significant sources
of phosphorus and nitrogen in the environment are domestic and
industrial waste effluents, agricultural run-off, detergents, and
animal and plant processing wastes. Nutrients can also be released
to the stream from bottom sediments and from decomposing plant and
animal matter.
A proposal has been made to impound the Jordan River in the vicinity
Of the Jordan Narrows, producing a shallow reservoir with a maximum
depth of about 60 feet. Inspecting the phosphorus and nitrogen con-
centrations from the June and August 1972 studies gives an indica-
tion that a major problem may occur (Tables A—2 and A—3). At the
stations at Saratoga Springs Rd. (JR-l) and the Narrows Pumping
Station (JR-3), the total phosphorus levels were 0.14 mg/l and
0.22 mg/l, respectively (Figure 14). The total nitrogen levels
were 1.87 mg/l and 2.19 mg/l (Figure 15). Water Quality Criteria
published by the National Technical Advisory Conuiittee suggests
that the amount of phosphorus entering lakes or reservoirs not
exceed 0.05 mg/l. The Jordan River in the area of the proposed
impoundment contained three to four times this suggested limit
during the study period. Water Quality Criteria published by the
State Water Quality Board of California reports that a total nitro-
gen level of less than 0.6 mg/l would not support large growths of
aquatic plants. The Jordan River contained three times this level
in the Impoundment area. The phosphorus and nitrogen levels In
the river appear to increase even more moving downstream to the
mouth (Figures 14 and 15).
By impounding the Jordan River, with its high concentrations of
nutrients (phosphorus and nitrogen), It is probable that large algal
blooms, extensive growths of aquatic plants and fish mortalities
would occur. As indicated in the discussion on dissolved oxygen,
there already appears to be a significant amount 0 f algal photosyn-
thetic activity.
Nineteen sampling stations were established at several selected
locations on tributaries and canals for examination of the irriga-
tion return flow contribution to the nutrient levels at these
locations. Included In the study were stations on Mill Creek,
Jordan and Salt Lake City Canal, Upper Canal, Big Cottonwood Creek,
Little Cottonwood Creek, East Jordan Canal, and the Sandy—Draper
Canal. The location of each station and the results of the examina-
tion appear in Table 3. Results of this study Indicate that with
the exception of the extreme upstream stations on Mill Creek, Big
Cottonwood Creek, and Little Cottonwood Creek, the phosphorus con-
centrations at all remaining stations exceeded the 0.05 mg/l suggested
limit. The nitrogen concentrations were equally high,

As part of the August Jordan River Study, special round-the-clock
samples were taken at stations established in the vicinity of the
Utah State Prison. Samples were analyzed for total and fecal coliform
and dissolved oxygen concentrations. Sampling stations were established
in the effluent ditch from the waste water treatment facility of the
Utah State Prison (p-l), in Corner Canyon Creek upstream from the
confluence with the prison effluent ditch (DC-i), and in Corner Canyon
Creek downstream from the effluent ditch and prior to the confluence
with the Jordan River (DC-2).
Results of this study indicate that the total and fecal coliform
concentrations in the prison effi 1 uent ditch reached mean densities
of 306,250 and 262,300/100 ml, respectively (Figure 16). The
effect of the wastes entering Corner Canyon Creek from the prison
effluent ditch caused the total coliform concentration to increase
from a mean of 5950/100 ml upstream of the ditch to a mean of
97,420/100 ml downstream from the ditch. The fecal coliform values
likewise increased from a mean of 3545/100 ml upstream to a mean of
82,385/100 ml downstream (Figures 17 and 18).
Dissolved oxygen measurements at these stations indicated that the
average DO in Corner Canyon Creek decreased from 7.3 to 5.8 mg/i
after the influence of the waste ditch from the prison (Figure 19).
The dissolved oxygen in the prison effluent ditch had an average
concentration of 2.5 mg/i.
Biology
Methods
The biological study of the Jordan River (August 14-23, 1972) was
conducted to supplement data obtained by the Utah Department of
Fish and Game in its initial investigation in 1965-66.
Since the biological community is a good indicator of the severity
of pollution, an investigation was made of the benthic organisms,
algae, and existing fish populations in the river. Access to past
data made it possible to compare trends in water quality.
A total of twenty-six sampling locations was selected on the Jordan
River and several of its tributaries. (Biological sampling loca-
tion descriptions are listed in Tables 4, 5, and 6.) Sampling sta-
tions were chosen on the basis of their relevance to existing data
and also how pertinent they might be in reflecting changes in that
data. All types of populations were not sampled at each location
if it was felt that they could not show further change in water
quality or were repetitious. The types of samples taken at each
of the biological sampling stations are listed in Table 7.
Benthic sampling was conducted by examining the substrate and
attached debris that might provide a suitable habitat for various
organisms. Quantitative samples were taken with a square-foot

Surber sampler when shallow riffle areas were present and with a Peterson
dredge when riffles were absent or substrate made the use of the Surber
impractical. Qualitative samples were collected with U.S. No. 30 sieves
and small mesh dip nets. All samples were washed through No. 30 sieves in
the field, placed in pint jars, and preserved with 10% formalin. They
were then packaged and transported to EPA’s Regional Laboratory in Denver
for analysis. In the laboratory, the samples were picked, sorted, and then
classified to the lowest possible taxononhic groups, hereafter referred to
as “kinds.” When the number of organisms was too large to count in a
reasonable amount of time, or the sample was loaded with debris, an aliquot
of the sample was counted. This number was then equated to the entire sample,
averaged with other quantitative samples of that station, and then calculated
to numbers per square foot. The percentage of each kind of organism was also
listed. A total of twenty-three stations was examined for presence of
benthic fauna (Table 4).
Seventeen stations on the Jordan River were sampled for algae (Table 5).
Qualitative grab samples of periphyton were collected from attached debris.
They were placed in pint jars and preserved with 5% formalin. All samples
were then put in dark storage and transported to the laboratory for processing.
Identification was done with a phase contrast microscope and all specimens
were taken to the lowest taxonomic group.
A fish population study was also conducted at thirteen stations selected
along the length of the river (Table 6). The main objective was to determine
the composition of populations in different sections of the river. The
program was one of shock, count, and release. Game fish were weighed and
measured before being released. Some specimens were preserved in 10% formalin
for later identification. Equipment included a transformer capable of pro-
ducing A.C. and pulsating D.C.; a seven horsepower, sixty-cycle generator; a
probe with 200-foot leads; dip nets; and a 16-foot john boat equipped with
a 25 H.P. motor that was used when wading was impossible. Shocking was most
effective using alternating current at 160-170 volts and 6-8 amps.
Benthic Organisms
In an unpolluted situation many kinds of organisms can exist, but because of
predation and the high competition for space and food each kind is low in
numbers. Invertebrates usually associated with this type of habitat are
pollution-sensitive kinds, such as stoneflies, mayflies, hellgrammites,
caddis flies, and riffle beetles. All these are valuable fish-food organisms.
If nutrients are added to a river, they may be beneficial as long as the
rate of enrichment does not exceed the assimilative capabilities of the
aquatic life present. If it does not, one finds many kinds of organisms
in large numbers. However, if enrichment exceeds assimilation, the physio-
chemical properties of the water are affected, resulting in varying degrees
of pollution. As organic pollution increases, there is a decrease in kinds
and numbers of sensitive organisms and an increase of more tolerant forms
such as midges, leeches, and sludge worms. If organic pollution becomes
severe enough, there will also be a reduction in the kinds and numbers of
tolerant organisms.
- 34 -

-------
In the 55-mile course of the Jordan River, it receives effluents from
ten domestic wastewater treatment facilities. Depending upon the degree
of organic load added to the river, the benthic community reflected an en-
riched, moderately polluted, or severely polluted environment. Aside from
the sources of organic pollution mentioned above, the headwaters of the
Jordan River in Utah Lake, and several of its tributaries, also receive
waters that have adverse effects on its quality. Other sources of pollution
to the Jordan come from industry and irrigation return flows.
The reach of the Jordan River from Utah Lake downstream to the Jordan Narrows
Diversion Dam had a moderately swift current flowing through a 3- to 12-foot
deep channel. The bottom substrate was composed of shifting silt and sand.
Quantitative sampling of the bottom revealed only low numbers of pollution—
tolerant sludge worms (18 per sq. ft.). Other organisms were unable to
exist due to the imcompatible habitat the substrate afforded. Even though
the combination of a shifting silt and sand substrate and the high turbidity
of the river is not conducive to the progagation and maintenance of the more
sensitive organisms, qualitative samples taken from attached debris did
indicate the quality of the water was sufficient to support some of the less
tolerant forms (Table 8). The kinds of organisms increased from seven to
eleven in the stream reach from Utah Lake downstream (stations 1 through 3,
respectively) to the Jordan Narrows Diversion Dam, indicating the water
quality was improving as some of the silt precipitated out in the river’s
slower stretches.
A marked decrease in kinds of organisms was found at station 4 inuiediately
downstream of the diversion dam. There was a drop from eleven at station 3
to five at station 4. However, the decrease was not necessarily caused by
a degradation in water quality. Most of the organisms found were of the
clean water varieties. Physical characteristics of the river at this point
made it nearly impossible to sample with available equipment. The river,
although only one-third its original volume due to irrigation diversions,
was deep and very swift. The bottom was composed of large rocks and boulders
which were covered with attached algae or periphyton. The swift flow of
turbulent water prevented the settling out of suspended materials and thus
allowed sensitive organisms to inhabit the bottom.
Downstream approximately four miles, the benthic community at Bluffdale
Road (station 5) increased to 13 kinds of organisms, numbering 1399 per
sq. ft. (Table 8 and Figure 20). Although the majority were pollution
sensitive, the large numbers per sq. ft. indicate an enriched situation.
This part of the river was characterized by alternating riffle and pool
areas, and was also the first station where clear water was encountered.
A substrate of rocks, gravel, and sand provided an excellent habitat for
benthic organisms and supported a healthy growth of aquatic plants. Water
at the previous stations had a green tinge due to the abundance of free
floating algae. At station 5, water clarity and a 7-8°F drop in water
temperature from the upstream stations were primarily due to cold water
springs in the area. This area was also selected as the upstream control
for the Utah State Prison sewage treatment plant (S.T.P.) effluent which
discharges into Corner Canyon Creek and then to the Jordan River.

-------
At 12600 South (station 6), or the first station downstream from the prison
S.T.P., there was a decrease in benthic organisms from 13 kinds at station
5 to eleven kinds. The reduction of two kinds of organisms is not as important
as the 40% decrease in the numbers of benthic fauna per sq. ft. from the
previous station to this one. Although some of the reduction might have
been caused by dredging operations in past years, the main cause was attributed
to organic pollution. This is further evidenced by the fact that the per-
centage of sensitive organisms per sq. ft. decreased from more than 85%
of the total number to about 7% at this station.
Although there was approximately a 300% increase in the numbers of organisms
at 10600 South, there was again a decline in the percentage of clean-water
organisms and over 85% of the invertebrates collected were pollution-tolerant
types, indicating organic enrichment had progressed to the point that the
more sensitive organisms were unable to properly compete for available habitat.
At station 8, 9000 South, the river was both losing the cooling effects of
the springs and becoming turbid due to irrigation return flow from Dry Creek.
But water quality had improved sufficiently enough to allow percentages of
less tolerant organisms an opportunity to increase slightly from about 2%
to nearly 12%. This station was the upstream control for the Sandy S.T.P.
The largest number of kinds of organisms (16 total kinds) was found at
7800 South. The reason for this was entirely due to the influence of
Bingham Creek. In years past the Utah-Idaho Sugar Company disposed of
their wastes in the creek. Beet wastes discharged to Bingham Creek, flowed
into the Jordan, and degraded water quality to the point that only pollution-
tolerant organisms were able to exist (Hinshaw 19-). The plant has since
ceased operations and the quality of the Jordan River in the immediate area
downstream has been improved greatly by the waters of this tributary. Therefore,
a cursory glance at the data presented in the tables for this station could
be quite deceiving. Even though 16 kinds of organisms were found in the
river directly downstream from the mouth of Bingham Creek, only four types
were found in a quantitative sample taken immediately upstream of its mouth.
This would indicate that the Sandy S.T.P. is definitely advesely affecting
the river. A black coating on the bottom of the rocks caused by anaerobic
decomposition of organic matter also indicated organic pollution.
The downstream station used to check the effects of the Tn-Community S.T.P.
was located at 6400 South. There was a drop from 16 to 11 kinds of organisms
at this location, but the change cannot be entirely attributed to detrimental
effects caused by the S.T.P. upstream. As previously mentioned, the waters
added by Bingham Creek slightly improved water quality in the Jordan River, but
the effect was evident only in the immediate vicinity of the confluence. If
the one quantitative sample taken directly in the influence of the creek at
7800 South was excluded, the benthic community at the peripheral margin of
the creek’s inflow would compare quite closely with those samples taken at
6400 South -- the only difference being in the increase of pollution-tolerant
organisms at 6400 South from 176 per sq. ft. to 556 per sq. ft., respectively.
There was a decrease intotal kinds and numbers of organisms at 4800 South
(refer to Table 8). Over 95% of the organisms found in the quantitative
samples were pollution-tolerant organisms, indicating a high degree of pol-
lution. This station was the upstream control for the Murray S.T.P.
- 38 -

-------
Between the sampling station at 4800 South and station 14 at 4500 South,
Little Cottonwood Creek enters the river. Samples taken on this creek
showed that it supported a balanced and competitive clean water environment
in its headwaters. In just a few miles of its East-to-West course across
Salt Lake City, the creek picked up nutrients and silt from several irrigation
canals, and the rock and cobble substrate of upstream was replaced by silt
and organic debris. This absence of good substrate made it difficult to
determine what aquatic life the water could support. The quality of water
from this tributary was sufficient to dilute the Jordan enough to improve
the numbers and kinds of organisms found at 4500 South. Populations per sq.
ft. increased from 277 at 4800 South to 1065 at this station, and from 9 to
12 kinds. Any effects that the Murray S.T.P. discharge, which is located
between these two stations, had on the river were limited to a short reach
of river and were not evident at this station.
Big Cottonwood Creek enters the river between 4500 South and 3300 South.
Samples taken on the creek upstream from the Salt Lake County Cottonwood
S.T.P. revealed about the same situation that was found on Little Cottonwood
Creek; i.e., an environment that proceeds from clean to enriched in a relatively
short distance across the city. The 4500 South Station did support a fair
diversity of kinds (12), but most of them were pollution-tolerant or moderately
sensitive organisms. At 3300 South, or the downstream station for the Cotton-
wood S.T.P., the number of kinds of benthic organisms decreased by approximately
50% and the sludge and silt substrate supported only the most pollution-tolerant
organisms. The plant discharge definitely contributesto the degradation of the
river. (Table 8).
Although some sensitive organisms were found in all the previous stations,
the river in the vicinity of 3100 South, 2100 South, 300 South, and 1800 North
supported only those kinds of organisms that were pollution tolerant. The
number of kinds varied slightly, from three to seven, as influenced by
entering tributary streams, but on the whole this section of river was highly
degraded by organic pollution.
The last two stations at Cudahy Lane and the State Canal showed some slight
improvement. The total number of kinds, as well as the number of organisms
per sq. ft., increased. Also, examp’es of sensitive organisms were found
on attached debris, but quantitative samples of the substrate still showed
only pollution-tolerant benthic organisms to be present.
Electra-fishing (Qualitative Fish Sampling )
The State of Utah has classified the waters involved in this investigation
as class “C” waters. Utah Lake and the Jordan River from Utah Lake down-
stream to the Utah County Line has been further classified as class “CW”
waters with the remainder of the Jordan River from the Utah County Line
downstream to the Great Salt Lake classified as class “CC” waters. Appendix
Table B defines these classifications.
The Jordan River supported a fish population that was predominatly rough
fish (Tables 9 and 10). Warm water game fish species were found mainly
in the stretch of stream from Utah Lake to the Jordan Narrows Diversion
Dam. A few white bass were collected as far downstream as 5770 South,
but the small numbers of fish collected indicated marginal populations
- 39 -

-------
probably caused by the colder temperatures at 12400 South St. and polluted
conditions at 5770 South St.
Only one reach of water in the vicinity of North Prison Road produced a
representative of a cold water fisheries (Tables 9 and 10). This single
specimen was a brown trout weighing about 3½ lbs. In the northern most
section of the river from 4800 South to the river’s mouth at the Great
Salt Lake, only pollution-tolerant rough fish were found. The most numerous
kinds and numbers of fish were found in the southern end of the river. Here,
the habitat had not been too severely disturbed by dredging operations and
organic pollution had not destroyed the majority of fish food organisms.
Several problems were encountered during fish-shocking. In most areas of
the river the water was extremely turbid and many fish that were shocked
were not observed. Some fish, when shocked, tend to sink and roll along
the bottom until out of the electric field. As a result, the data presented
represents a minimum number of species collected.

Algae
All periphyton samples collected were classified to genus level.
The diatoms were cleared according to the acid digestion method
suggested by Patrick and Reimer, 1967. Following the digestion
procedure the samples were mounted permanently with Permount media.
The following results are strictly qualitative, and Table 11 will
serve as a check list of algae present in the Jordan River on
August 18, 1972:
Four divisions of algae composed of 36 genera were col-
lected from the Jordan River periphyton samples. The
Bacillariophyceae (diatoms) were the most numerous genera,
with a total of 22 different kinds being identified. Two
other members of the Chrysophyta (yellow-green algae)
were also collected, Vaucheria sp. and Tribonema sp. The
Chiorophyta (green algae) were the next most predominant
in diversity, being represented by nine genera. The
Cyanophyta (blue-green algae) collected were limited to
the genera Oscillatoria sp. and Anabaena sp. Pyrrhophyta
(brown algae) were the least represented of the four
algal divisions, with only Ceratium sp. being collected.
As indicated earlier in the discussion of phosphorus and nitrogen
levels in the Jordan River, the river contains a high concentration
of these nutrients.
In enriched situations, such as exists in the Jordan River, algal
populations tend to shift from predominantly green algal conimuni-
ties to blue-green algal communities. Such blue-green communities
usually produce taste and odor problems and unsightly scums along
the shoreline.

SUMMARY AND CONCLUSIONS
The Utah Lake-Jordan River Basin, a semi-arid interior drainage
basin located entirely within the State of Utah, is one of the
areas designated by the Environmental Protection Agency as a Priority
Basin. Additionally, Utah Lake is listed as a target area in EPA’s
National Eutrophication Control Program. In Support of the Environ-
mental Protection Agency’s Priority Basin Concept, EPA Region VIII
personnel conducted field investigations in the Utah Lake-Jordan
River Basin in June and August 1972. These studies were focused
in the areas of Emigration Canyon and the main stem of the Jordan
River.
Bacteriological examination of the Emigration Canyon area indicated
the mean coliform densities in the headwaters of the creek that runs
through the canyon to be generally low (201100 ml total coliforni
and 6/1.00 ml fecal coliform). Furthermore, discharges from indivi-
dual waste water disposal facilities in the vicinity of or directly
into the creek have increased the coliform densities in the creek
to values in excess of the 5,000/100 ml criteria for waters in the
Basin. Waters in the creek, particularly in the reach where the
excessive coliform densities occurred, are used by the local resi-
dents for the sport of “tubing”--riding an innertube downstream.
The results of the microbiological study of the Jordan River indi-
cated that the mean total coliform densities in the headwaters of the
river to be less than the 5,000/100 ml criteria for waters in the
Basin (1118/100 ml IC mean at JR-i), a condition that existed for
only 13 river miles downstream. Wastes from various sources enter-
ing the Jordan River along the reach from 7800 South St. (JR-9) down-
stream through the remainder of the river caused the total coliform
densities in the river to exceed the 5,000/100 ml criteria on the
basis of the daily grab samples. From 3300 South St. (JR-l3) down-
stream to the mouth of the Jordan River, the mean densities at each
station in this reach exceeded the coliform limit.
Average dissolved oxygen values in the Jordan River were greater
than the cold water fishery criteria (6.0 mg/l) from Utah Lake down-
stream to and including the station at 3300 South St. (JR-13). From
2100 South St. (JR-14) downstream to the mouth of the river the average
0.0. values decreased and were less than the 6.0 mg/i criteria. At
Cudahy Lane (JR-17), the average D.O. was 3.7 mg/i.
Significant photosynthetic activity is taking place in the Jordan
River in about the upstream third of the river. Single 0.0. values
as high as 19 mg/i have been measured. The results of a round-the-
clock study at a station in this reach (Fairfield Rd., JR—2) indicated
that the dissolved oxygen concentrations varied from 7 to 12 mg/i over
a 24-hour period.

-------
Total phosphorus and nitrogen concentrations in the Jordan River
were excessive. This is particularly significant in the area of
the proposed impoundment of the river where both the phosphorus
and nitrogen levels exceeded those considered as limits for waters
entering impounded areas. It is probable that by impounding these
waters large algal blooms, extensive growths of aquatic plant, and
fish mortalities would occur. With the exception of the extreme
upstream stations on Mill Creek, Big Cottonwood Creek, and Little
Cottonwood Creek, the nutrient concentrations at all remaining
stations on these tributaries to the Jordan River were excessive.
Wastes from the Utah State Prison are contributing to a significant
increase in the total and fecal coliform concentrations in Corner
Canyon Creek, tributary to the Jordan River. Likewise, wastes enter-
ing the creek from the prison effluent ditch have caused a reduction
in the dissolved oxygen resources of the creek.
A biological study conducted on the main stem of the Jordan River
(August 14-23) showed that approximately 70% of the water in the
river was adversely affected either by the headwaters from Utah Lake
or by organic pollutants from numerous waste water treatment plants
and irrigation return flows.
For approximately the first nine to ten miles of the river’s course,
from Utah Lake to the Jordan Narrows, a shifting, unstable substrate
and highly turbid water limited the benthic invertebrate community
to from seven to eleven kinds of organisms. The fish population in
this reach of river was composed of five kinds, predominatly warm
water game fish.
Downstream from the Jordan Narrows to about 7800 South (15 stream
miles), the river supported a diversity of benthic organisms number-
ing from 11 to 16 kinds. In the upstream portion of this area, the
substrate was composed of course sand and cobbles. Water quality was
both augmented and enhanced by numerous springs which decreased the
temperature and turbidity, thus permitting the river to support pol-
lution-sensitive benthic organisms. Proceeding downstream from Bluffdale
Rd. (14600 South), water quality was progressively degraded. Downstream
from 7800 South, organic pollution had increased to the point that the
only areas of recovery in water quality were found in the confluences of
tributaries. One brown trout was collected from the upstream section
of the above reach (North Prison Rd.), indicating that a portion of
the river supported a cold water fishery.
Approximately 30 miles of river, from 7800 South to the Great Salt
Lake, received increased organic pollution from waste water treatment
plant effluents and irrigation return flows. The river had been
dredged and the bottom consisted mainly of silt, sand, and organic
sludge. The available habitat supported organisms more tolerant
to pollution. Fish populations in this reach of river consisted
- 4 -

-------
of rough fish that were able to exist in water degraded by organic
pollution.
If additional biological studies are to be conducted on this river
system, efforts should be concentrated on Utah Lake and its tributaries
and the section of the Jordan River from 9000 South, downstream to
the Great Salt Lake.

-------
STREAM CLASSIFICATIONS
The following stream classifications adopted by the Utah Water Pollution
Committee apply to the waters involved in this investigation:
Jordan River - From Utah Lake to Utah County Line. CW
Utah Lake Utah County CW
Jordan River and Tributaries - From Utah County
line to Great Salt Lake. CC
C’ass “C” Waters shall be so protected against controllable pollution,
including heat, as to be suitable at all times for domestic water supplies
which are treated before use by coagulation, sedimentation, filtration, and
disinfection. Class “C° waters shall be suitable without treatment for
aesthetics, irrigation, stock watering, propagation and perpetuation of fish,
other aquatic life, and wildlife, recreation (except swimming) 1/, as a source
for industrial supplies, and for other uses as may be determine by the
Committee and Board.
It shall be unlawful to discharge or place any wastes or other substances in
such a way as to result in:
(a) Materials that will settle to form objectionable deposits;
(b) Floating debris, oil, scum and other matters;
(c) Substances producing objectionable color, odor, taste or
turbidity;
(d) Materials, including radionuclides, in concentrations or
combinations which are toxic or which produce undesirable
physiological responses in humans, fish and other animal
life and plants;
Ce) Substances and conditions or combinations thereof which
produce undesirable aquatic life; or
(f) Other constituents which will interfere with the stated
Class “C” water uses; or
(g) The following specific standards being violated in any
Class “C” waters:
]j In bodies of water where natural purification action can be shown to result
in water quality consistent with the “CR” quality standard, swimming may be
permitted subject to specific approval by the State Board of Health, not-
withstanding any different initial classification.

-------
1. Chemical and radiological standards shall be as prescribed for drinking
water by “Public Health Service Drinking Water Standards, 1962.”
2. Radioactive substances shall not exceed 1/30th of the MPC
for continuous occupational exposure in National Bureau o
Handbook 69 or result in accumulations of radioactivity in
and animals that present a hazard to consumers.
3. Hydrogen-ion concentration shall not exceed the range described by a pH
of 6.5 to 8.5, nor shall it change more than 0.5 pH unit, from other than
natural causes.
4. Monthly arithmetical mean coliform density shall not exceed 5000 per 100
milliliters, as determined by standard multiple-tube fermentation or membrane
filter techniques; except that 20% of all samples collected in any month
may exceed this standard if no more than 5% of all samples collected in
the same month exceed a coliform density of 20,000 per 100 milliliters;
AND, monthly arithmetical mean fecal coliform density shall not exceed
2000 per 100 milliliters.
5. Monthly arithmetical mean biochemical oxygen demand (BOD) shall not exceed
5 milligrams per liter; except that 20% of all samples collected in any
month may exceed this value if no more than 5% of all samples collected
in the same month exceed a BOD of 10 milligrams per liter.
6. Dissolved oxygen shall be not less than 5.5 milligrams per liter.
Class “CC” Waters shall be protected as Class “C” waters, and also against
any wastes or activities which alone or in combination will cause an in-
cremental increase in temperature of s 8 id waters of more than 2 0 F., or an
elevation in such temperature above 68 F., or will cause the dissolved
oxygen level of such waters to fall below 6.0 milligrams per liter.
Class “CW” Waters shall be protected as Class “C” waters, and also against
any wastes or activities which alone or in combination will cause an incre-
mental increase in temperature of said waters of more than 4°F., or an elevation
in such temperature above 80°F.
Class “CR” Waters shall be suitable for swiming as well as for other uses
specified and shall be protected as Class “C” waters except for specific
standard No. 4 which is modified as follows for application to Class “CR” waters:
Monthly arithmetical mean coliform density shall not exceed 1000 per
milliliters, as determined by standard multiple-tube fermentation or
membrane filter techniques; no more than 20% of all samples collected
in any month may exceed a coliform density of 1000 per 100 milliliters
and no more than 5% of all samples collected in the same month may
exceed a coliform density of 4000 per 100 milliliters; AND, monthly
arithmetical mean fecal coliform density shall not exceed 200 per 100
milliliters, provided that no more than 10% of all samples collected
in any month shall exceed a fecal coliform density of 400 per 100
milliliters.
