INTRODUCTION The Sweetwater County Conservation District, in order to achieve the goals and objectives of the BitterIKilipecker Watershed Advisory Group (BKWAG), desired to acquire a comprehensive historical perspective related to water quality found in the Bitter Creek Watershed, hydrologic unit code # 14040 I 05. Bitter Creek and Killpecker Creek, a tributary to Bitter Creek are the focus of this document although cursory information for other tributaries within the watershed is referenced when appropriate. The primary constituents of concern were fecal coliform and chloride concentrations. This report, prepared by Rik Gay, Lost Iguana Consulting Inc., presents the results from a historical reference literature search and an electronic database search, and anecdotal personal interviews from local citizens whom provided a first hand historical water quality based perspective of the conditions found in the Rock Springs area. This poem below, written by David G. Thomas a Rock Springs resident around the tum of the 20 lh century, commemorated the general feeling toward Bitter Creek in the poem below.

"Here's Bitter Creek; an empty thing, Save when the melting snow in spring Rolls madly down the mountainside And fills its channel deep and wide. At times it nearly overflows With dirty water, as it goes Beyond the home of Noah Walters, Where for a moment falters To proudly view Jack Noble's castle Before it starts to Ii ght and wrestle With old bottles, cans, and sundries Certain men throw in on Sundays, Mondays, Tuesdays and on all days. On it goes- its filthy charges Dash against old Uncle George's House on stilts, from which it dodges Past the stable of Frank Hodges, By Woll Dickenson's humble dwelling; Chopping, grinding, booming, swelling, Curling, whirling, onward ever Till it flows into Green River, 0, Classic Creek! Rich in tradition Of tragedy and superstition; Your yearly, reckless inundation Provides the means of sanitation; Besides, the Lord knows very well When you have purged yourself of smell And other things that much displease You've freed the town of foul disease."'

HISTORICAL LITERATURE This first section will begin with information and quotes from diaries and literature from the earliest written descriptions from within the Bitter Creek watershed. The Bitter Creek area first became of interest in the mid-1800's as Indian trouble in the South Pass area promoted soldiers and emigrants to begin looking for an alternative route west. Surveyors from the transcontinental railroad were also looking for a viable route through Wyoming. Both soon found that the Bitter Creek drainage provided the most reasonable passage through the area. A bonus to the railroad was the discovery of vast coal seams within the watershed from which the trains could extract the energy needed by the nation for decades to come.

Some of the observations of the Bitter Creek area from the pre-settlement period are found below. Journal entries by Surveyor , September 1850'; September 14th; "We passed the mouth of Bitter Creek ... so rapid is the disintegration of the sandstone bluff ... is almost entirely destitute of even a spear of grass." "crossing the creek, which will be somewhat difficult, as the bed of the stream is not infrequently at a depth of twenty feet ... with perpendicular banks on each side." th 0 September 15 ; "10 miles upstream of 400 34' 41",109 23' 09" (south of the point of rocks area). Bitter Creek at the camp flows in a bed twelve feet below the plain of the bottom and the water at its present stage is about sixty feet wide by six inches in depth. But the accumulation of the large piles of flood-wood shows that during spring freshets the whole valley, here about 1000' feet wide, is completely covered in water."

Journal entries by Major J. Lynde, December 18573 December 3'd; "took breakfast at the mouth of Bitter Creek ... grass very scarce, it has a bitter brackish taste, wood is very scarce, nothing but greasewood and small sage. " December 4'h; "The water is not fit for man to use, being at least 118 salt."

Journal entries by A. Howard Cutting, 1863' June 7'h; Black Butte Station "but the water in Bitter Creek, all we had yesterday and all we are likely to have today, is as strongly impregnated with alkali we can hardly drink it without using Sartaric Acid or Vinegar in it. Sides of the bank crusted .... water is a dirty reddish color and tastes like no one can know until they try it. Tim Connell's horse sick from alkali water." th June 8 ; Salt Wells "The well water is very salty and tastes and acts, when used for washing, just like seawater .... Bitter Creek which runs directly past the well is almost unfit for any purpose. Seems to grow worse the further we travel on it." June 9'h; "Bitter Creek is too miserable a stream to have a name. The water grows worse, so bad now, that even whiskey won't help it. ... It gives us a kind of pain in the stomach which is hard to bear. Pokers child is very sick from the effects of the water.;"

From these descriptions it is clear that in pre-settlement days the landscape in the Bitter Creek watershed was barren and the water in Bitter Creek so saline that is was not palatable and not likely useable for any purpose. No references to Killpecker Creek were found.

Settlement of the area occurred in the early 1900's. Numerous descriptions were found that allowed the reader to appreciate the rapid, spontaneous way the town came together and its impact on Bitter Creek: "Perhaps the feature of the early day Rock Springs that is etched most deeply in my memory is that of Bitter Creek meandering through the center of town. It entered from the east - through East Flat, flowed past the coal chutes, turned slightly north and cut across lower K Street. It flowed on through what is now Bunning Park to join Killpecker Creek near the end of Grant Street on West Flat. A red steer bridge crossed Bitter Creek on lower K street and business houses were built to the edge of the creek banks. On the north side of the creek, on the ri ght, a group of buildings, occupied by Chinese, clung to the creek bank. As you passed across the bridge on foot you heard wastewater from the buildings splash into the creek. The creek was offensive to the eyes-for, indeed, it was an eyesore, but it was more offensive to the sense of smell- for it smelled to a degree that defied description during the dry summer and fall months. "l

"Through the years Bitter Creek wiggled, wormed and squirmed its shifting way through the heart of the village, and through it' s early spring floods bore resemblance to the turbid Tiber, the early settlers, from dearth of money and materials wherewith to build, dug into its sheltering banks as a protection against wintry blasts, moving out when forced by spring and mid-summer floods. No provisions were made for sanitation, and all toilets were outside. It was not until 1924 that the city, with a population then of 8000, was to realize that it enjoyed the doubtful notoriety of being the largest city in the United States devoid of any system of sanitary sewerage. And it was not until July, 1926, that the oft-recurring overflowing of Bitter Creek's turgid waters was to fail to find homes located in its channel. Water for domestic use was hauled by Ed Clegg from the sulphur spring north of town to the storage barrels that stood before the houses and stores, for twenty-five cents a barrel. Later the railroad hauled water from Green River and Point of Rocks in tank cars and distributed it to the homes and stores at the same cost" 6.

"First among these responsibilities, he (newly elected Mayor Peter Bunning) felt, was Bitter Creek. The creek, an open sewer, boiling perilously into flood in the spring, and smelling to heaven during the long dry season, chose to overflow the April after the new Mayor' s inauguration. The dugouts that lined it's banks in the pioneer days of Rock Springs had persisted, and a number of families had even ventured into the channel itself, building and filling, until every flood inundated dozens of homes. The flood of 1924 was no exception. Simultaneously with the carrying on of the rescue work and salvage, Mayor Bunning began a crusade to convert the hazardous and pestilent stream into the beginning of a modem sanitary system . .... Bitter Creek was filled up and converted to a street, the creek was detoured from a point on Rainbow Avenue to a point west of Elk Street, where it again united with the original Bitter Creek channel, and a complete sanitary and flood sewage system was installed. All of the work was completed by the Spring of 1926. On July 10" of that year a flood as serious as the one in 1924 came down, but instead of inundating homes, washing away possessions, and driving families to spread their beds on the roof, this time the rushing water was merely a spectacle for the miners to watch." 7

HISTORICAL WATER QUALITY DATA An electronic database search utilizing the UWYO Water Resources Data System Water Quality Database based upon rectangular latitude 1 longitude boundaries of 41° 58' 00" North, 41° OS' 00" South, -109° 27' 00" West and _108° 10' 00" East was executed in February 2003. The results of that search provided 277 stations with water quality data. To reduce the number of data sets the specific lat/long of each station was evaluated and 104 stations were found to reside outside of the Bitter Creck and Killpecker Creek watershed boundaries, the project area proper. Of the remaining 173 stations, four (4) were wells with unrelated data. The remaining 169 stations were then classified as to collecting agency/organization.

Each data set was then evaluated to determine which data sets contained project relevant data, specifically fecal coHfonn and chloride data, to establish historical levels of those constituents. Of those 169 surface water data sets, four (4) from Bitter Creek and one (I) from Killpecker Creek were found to contain credible fecal colifonn data. Note that the WDEQ listing data is not contained in this data set as it is still considered PROVISONAL as of this report. Those data sets containing fecal colifonn data were:

While the two Green River water quality monitoring stations are not located within primary project area, 0921700 was located immediately upstream of the Green River I Bitter Creek confluence and 092170 I 0 was located two miles downstream of the GreenlBitter confluence. Inclusion of those data sets allowed for analysis of the degree of influence that Bitter Creek, currently classified as a 2C water (those known to support or have the potential to support nongame warm water fish populations or spawning or nursery areas') which experiences negligible recreational contact opportunity, has the class 2AB (Cold Water Fisheries) Green River which has a significant potential for recreational contact.

Chloride data was found in 93 data sets. However, a majority of those data sets were single event. To accommodate analysis on a watershed scale multiple events per site are required. Nine (9) sites, eight USGS and one BLM, within the project area had sufficient sampling events for analysis and are listed in the table below.

WDEQ WATER QUALITY STA~-nARDS In order for the reader to gain an understanding of the data presented in this report, an understanding of the current standards is first required. In this section the current WDEQ water quality standards for the constituents of concern to this effort are discussed. Fecal coliform and Chloride are the primary focus of this project, however a number of other closely related constituents are also discussed as they provide supplemental data for the two primary constituents.

Microorganisms such as fecal coliforms are present in all terrestrial and aquatic ecosystems. Most types are beneficial, functioning as agents for organic and synthetic chemical decompOSition, a small subset of microorganisms however are harmful. If taken into the. body they can cause sickness, disease and even death. As a group, these harmful microorganisms are known as pathogens Fecal coliform and E. coli are the indicator bacteria that are used as an indicator of general fecal contamination and to evaluate the potential for water contamination by harmful pathogens. Although indicator bacteria are not pathogenic in and of themselves, high numbers may indicate fecal contamination from leaky septic tanks, animal manure" or faulty wastewater lD treatment facilities • During the entire year, fL'Cal coliform concentrations shall not exceed a geometric mean of 200 organis ms per 100 milliliters (based on a minimum of not less than 5 samples obtained during separate 24 hour periods for any 30 day period), nor shall the geometric mean of 3 separate samples collected within a 24 hour period exceed 400 organisms per 100 milliliters in any Wyoming surface water" .

Chloride occurs naturally in streams. Wyoming streams generally contain low ambient chloride concentrations of less than 25 mg/1. However, some streams that drain areas high in natural salts will have higher ambient chloride levels. Stream chloride concentrations may increase due to introduction of oilfield produced water, industrial and municipal effluent, irrigation returns and Jow flow. Macroinvertebrates are sensitive to elevated chloride concentrations. Chloride values at or below 565 mg/I have been reported as not affecting the benthic aquatic community structure. The current WDEQ surface water quality standard for an instantaneous chloride concentration is 860 mg/I."

Surface water standards for conductivity or Total Dissolved Solids (TDS) are not currently established in Wyoming as these parameters generally pose no threat to surface water supplies, beneficial use, or aquatic organisms. However, a conductivity limit of 7500 umhos/cm has been set for point source effluent discharges. Wyoming ground water quality standards specify that TDS concentrations for domestic, agriculture, or livestock purposes will not exceed 500 mg/I, 2000 mg/I, or 5000 mg/I, respectively. Conductance is related to the number and chemical types of ions in solution. Although conductivity is not directly proportional to TDS concentration it can provide a reliable field estimate if a site-specific correlation between the two is established first. In general, the more dissolved substances present in water the higher the conductivity measurement. Conductivity depends on the temperature of the solution, the presence of ions, their total concentration, mobility and valence. Dissolved substances are required to establish and maintain a diverse macroinvertebrate community. However, water with a high specific conductance of greater than 6,900 urnhoslcm has been reported to negatively affect aquatic organisms whether the source was natural or man-induced.

Water pH is a Watershed Program BURP Monitoring core parameter. The pH for most mountain streams in Wyoming ranges from near neutral to slightly basic; plains streams are usually basic. pH values range from 0 to 14 standard unIts (SU). The pH of pure water at 7S.2E F (24E C) is 7.0 SU, defined as neutral. Water above 7.0 SU is considered basic while water with a pH below 7.0 SU is considered acidic. Chapter I, Wyoming Water Quality Rules and Regulations sets pH limits from 6.5 SU to 9.0 SU.

In Wyoming streams, sulfate is naturally present in waters in concentrations ranging from a few to several thousand mgll. Stream sulfate levels may increase from headwater to plains regions due to natural causes. Sulfate concentrations may be artificially increased due to introduction of oil field produced water, irrigation returns, industrial and other point discharge effluents. Increases in sulfate concentration appear to negatively affect benthic macroinvertebrates. In a reported study of streams in the Great Basin, as sulfate levels increased, macro invertebrate community diversity decreased. A sulfate concentration below ISO mgII was optimal there for macroinvertebrates. The State of Wyoming and USEPA have not established surface water quality standards for sulfate. Sulfate levels for Wyoming groundwater have been set at 250 mg/l, 200 mg/l, and 3,000 mgII for domestic, agricultural, and livestock uses, respectively (WYDEQ 1980).

HISTORICAL WATER QUALITY DATA ANALYSIS Fecal Coliform Once the monitored locations were reduced to those sites containing pertinent data, the data was then reduced again for analysis. In the table and ill ustration below, fec al coliform data from five sites is presented spatially as a general overview of where, and at what average concentration, was fecal coliform historically present within the watershed. A similar fecal coliform data points, the mean or average concentration at that site, and the percentage of data which exceeded the current WDEQ acute standard.

A general observation can be made thai historically, concentrations of fecal coliform bacteria increased dramatically in the lower reaches of the watershed. As the graphic on the following page shows, temporal anal ys is of the historical mean does indicate a gradual decrease in the mean concentration of fecal colifo rm bacteria over time, especially at the Kanda site.

Again, note the significant decrease in mean fecal coliform concentration at the Kanda monitoring location in 1981. During discussion of this phenomenon with members of the BK W AG it was remarked that the decrease coincides with the completion of the Jim Bridger Power Plant. It was noted that during the 10 years that the power plant was under construction that due to limited housing that many of the workers camped along the streambanks of the creeks in the area, A theory was developed by the BKW AG that the lack of adequate sanitary facilities to support such a large influx of workers and uncontrolled long-term camping was the likely source of the high concentrations of fecal coliform bacteria found in the area creeks during the time period indicated by the graph above.

An additional data set, Biner Creek above the confluence of Killpecker Creek, also contained a significant amount of fecal coliform data but was not included in the analysis of the five monitoring stations previously mentioned as the time period during which it was sampled did not coincide with the other stations. The graph below represents the additional data set and exhibits, albeit unacceptably high, a typical fecal coliform concentration winter/summer fluctuation.

While a good historical data set for the lower reaches of the watershed exists, with the exception of the provisional data compiled by the WDEQ, the most recent data is still 10 years old. The provisional WDEQ data set was a result of surface water monitoring conducted more recently, in 1999 and 2000. Because the data is still considered provisional it will be presented in this report only in general terms. Geometric means for fecal coliform bacteria obtained by WDEQ ranged from 26 colonies/lOOml to 929 colonies/lOamI. Water quality samples were collected in the summer of 1999 for fecal coliform bacteria analysis at three locations on Bitter Creek on five separate sample dates within a two-week period and resulted in exceedance of the "<200 mean" fecal coliform standard at two of the three locations. The following year the number of monitoring locations on Bitter Creek was increased to nine and sampled in May but did not result in significant levels of fecal coliform bacteria present at any of the monitoring locations. Several theories were explored in the resulting WDEQ provisional report but all were unsubstantiated due to lack of adequate current dala.

Water quality samples were also collected in both 1999 and 2000 fTom Killpecker Creek in conjunction with Bitter Creek investigation. The summer 1999 sampling regime resulted in a slight exceedance of the "<200 mean" fecal coliform standard. As was the case with Bitter Creek, the spring sampling in Killpecker Creek in 2000 indicated very low levels of fecal coliform bacteria.

A current (2003-2004) watershed wide fecal coliform data set would be very valuable for comparative analysis against historical data. Such data and subsequent analysis could provide important information as to continued trends as well as identification of potential areas in which best management practices could be applied to continue to minimize the health risks associated with high concentrations of fecal coliform bacteria.

Chloride Included in the table below is the number of Chloride data points at that site, the geometric Chloride mean concentration in milligrams per liter (mg/I) for that sample set, and the percentage of the sample events at which the WDEQ standard for Chloride (860 mg/I) was exceeded. Note that the sites are listed in the table spatially beginning at the top of the watershed and ending at the bottom of the watershed at the Green River as illustrated in the accompanying graphic.

Spatial analysis illustrates a cumulative increase from the headwaters to mid-way through the watershed near Salt Wells (322). Mean chloride concentrations from Killpecker Creek are historically the highest in the watershed and likely is at least partially responsible for the resultant increase in chloride levels further downstream. It should be noted however that the soils and geology contained within this watershed are naturally high in chloride and related constituents.

• 09216562, Bitter Creek: Of the 104 data sets for specific conductance, 31 % exceeded the recommended levels of specific conductance for livestock, 5000 mgtl, with a average value for the entire data set of 4,11 o. There were 55 data sets for chloride of which 14.5% exceeded the non-aquatic life standard of 860 mgll, with a mean of 322 mgll. Recommended sulfate levels for livestock, 3000 mgll, were also exceeded at 14.5% of the 55 data points with a mean of 1,333. Regressional comparative analysis was performed with sulfate and chloride. R-value for the regression was .84 indicating a strong relationship at this location and coincided with the exceedance rates. There was also a positive relationship between the two constituents and specific conductance .

• 09216750, Salt Wells Creek: The recommended specific conductance level for livestock was exceeded four times in the 55 sampling events with a mean value of 2,356. Significantly lower than that found at the Bitter Creek site approximately I y, miles distant. Neither the chloride levels nor the sulfate levels exceeded standards or recommended levels for livestock, with means of 137 ms'! and 1008 mgtl respectively. These were also significantly lower than those found at the nearby Bitter Creek site. The significant difference in the constituent levels between the two sites indicates that the source of chloride and sulfate is not localized and that overall it is much more likely that the upper Bitter Creek watershed as a whole is the main source.

• The two sites, 09217000 & 09217010, on the Green River were included as they are both found within two miles of the confluence with Bitter Creek, one just upstream and the other below. The intent was to determine the level of effect that Bitter Creek had on the larger waterbody. Direct comparison at the confluence was not possible as fecal coliform data had not been collected at the lower Bitter Creek sites nor did the sampling dates match. However, the Green River sites and the Bitter Creek site near Kanda (approximately nine miles upstream of the confluence) were sampled during comparable time periods and both had fecal coliform data.

• Analysis of the historical fecal coliform data obtained from the "Kanda" site on Bitter Creek show extremely high fecal coliform counts prior to October 1981. The average colony count at this site from July 1975 through October 1981 was 4-14,864 colonies/lOO mi. Then beginning at the next sample event, December 1981, the count dropped dramatically and remained low for the duration of the sampling events. The average colony count for that period, December 1981 - September 1983, dropped to 161 colonies/lOO mi. The most significant aspect, other than the very dramatic decline in fecal coliform, was the correlation with the Green River sampling site located approximately one mile downstream of the GreenlBitter confluence.

• The data set for the Green River monitoring sites was condensed to be inclusive of the time span during which both sites were monitored for fecal coliform bacteria, January 1974 - April 1987. Comparative analysis indicated a slight mean increase in discharge rate (3.96 cfs) from the upstream site 09217000, to that found at the lower site. However, the mean increase for fecal coliform between the two sites on an order of magnitude. For the period 09217000 had a mean fecal coliform count of 10 colonies/lOOml, during the same period the mean fecal coliform count for site 09217010 was 108 colonies/J OOml.

• Given the location of the lower Green River monitoring station and its relative proximity to the Town of Green River, attributing the increase of fecal coliform solely to Bitter Creek was not realistic. However, an anomaly in the Green River data provided an important correlation to Bitter Creek. Pre-1981, the fecal coliform acute standard (400 colli 00,1) at the lower Green River monitoring site was being exceeded 39% of the time with a mean fecal coliform count of 164 coloniesll 00 ml. From 1981 on through 1987 the exceedance rate drops to 3% and a mean of 16 coloniesll OOml. The timing of the dramatic reduction in fecal coliform bacteria in both the Green River and Bitter Creek at Kanda is almost identical, providing evidence of a strong correlation between the levels of bacteria at both sites.

DATA RELEVANT TO STREAM CLASSIFCATION Given the breadth of water quality parameters that have been historically sampled for 16 in the BitterlKillpecker watershed, in order to make the database manageable it is important to select parameters for analysis that will have bearing on the goals and objectives of the BitterlKillpecker Watershed Assessment Program and the BitterlKillpecker Watershed Advisory Group. The constituent creating the listing of Bitter and Killpecker Creeks was fecal colifonn, with chloride concentrations also being mentioned as a concern by a field report competed by WDEQ staff. The historical data for those parameters have been presented and discussed previously in this report.

The reclassification of both waterbodies is a major issue in the watershed. The current classification in the lower section of Bitter Creek, described as from the confluence of Bitter Creek and the Green River upstream to the town of Rock Springs, is categorized as 2C. 2C waters are those known to support or have the potential to support nongame wann water fish populations or spawning or nursery area. The section of Bitter Creek upstream of Rock Springs and 17 Killpecker Creek are both currently categorized as Class 3B waterbodies • Class 3B waterbodies are characterized as intermittent or ephemeral streams with sufficient hydrology to sustain communities of aquatic life at some stage of their life cycle. Generally 3B waters are identified by frequent wetland occurrences.

Therefore, given the current definitions of the stream classifications, the attributes andlor historical data parameters of the waterbodies analyzed should affect the viability of supporting aquatic life at some part of the organism's life cycle. Based current definitions, the presence of any warm water fish species during any period of it's lifecycle at some time in the year in the waterbodies could meet the classification criteria for 2C waters. Data presented in the 1993 Wyoming Game and Fish report "A Fisheries Survey of the Bitter Creek Drainage" presents data relevant to that component and indicates the presence that warm water fish species were present both the 2C and 3B sections of Bitter Creek and select tributaries of Bitter Creek. That report is found in the following section.

Other data relevant to the viability of the water bodies supporting aquatic life at some stage of the Iifecycle would be discharge or flow. Bitter Creek downstream of Rock Springs is a Class 2 stream, or by definition a stream with perennial flow. Both Bitter Creek upstream of Rock Springs and Killpecker Creek are considered Class 3, which includes intermittent and ephemeral streams. Streams categorized under this classification do not necessarily exhibit year-round flow. However, based upon available historical data it could be important to establish when during the year that discharge is normally present under normal conditions.

All historical flow/discharge data available from throughout the watershed was compiled, converted to a chronological database (by month) and analyzed and is presented on the following page. As previously noted, the point of delineation between class 2 and 3 streams within the watershed is the town of Rock Springs. Therefore, prior to analysis the data sets were divided into streams above Rock Springs, the Class 3 streams and those monitoring sites located on Bitter Creek (Class 2) downstream of Rock Springs. The data set for monitored locations downstream of Rock Springs was comprised of nine locations with 167 discharge data points obtained between August 3, 1966 and July 26, 1993. The data set for streams and tributaries upstream of Rock Springs consisted of 29 monitored locations with 778 discharge data points obtained during the period from August 19,1968 through September 30,1987.

A blank cell in the table only indicates that no historical data for flow was available for that site during that month and does not represent whether or not there was flow present during that period, just historically no monitoring occurred during that month at that site.

While in most months of the year the values were quite low, according to the available historical data Bitter Creek downstream the town of Rock Springs has flow in all months of the year and can be considered perennial. Data in the second "Upstream" table indicates that flow occurred in all months of the year throughout the upper watershed during the nineteen-year period during which discharge data was obtained. However, most of the averaged flow values are extremely low indicating intennittent andlor ephemeral streams hydrology. However there are times of the year when sufficient flows are present that potentially "sustain communities of aquatic life at some stage of their life cycle", thus meeting the current definition of a Class 3 stream.

SUPPLEMENTAL DATA (FISHERIES) Clarification of the stream classification of both Bitter Creek and Killpecker Creek is key to the overall goals of the BK WAG. While many attributes determine what the classification of a waterbody should be, the primary attribute that delineates between a class 2 series and a class 3 series waterbody is the presence of fish. The definitions of class 2 & 3 waters are found below:

"Class 2 waters are waters, other than those designated as Class I, that are known to support fish or drinking water supplies or where those uses are attainable. Class 2 waters may be rerennial, intermittent or ephemeral. There are four subcategories of Class 2 waters."J

"Class 3, Aquatic Life Other than Fish. Class 3 waters are waters, other than those designated as Class I, that are intermittent, ephemeral or isolated waters and because of natural habitat conditions, do not support nor have the potential to support fish populations or spawning, or certain perennial waters which lack the natural water quality to support fish (e.g., geothermal areas). Class 3 waters provide support for invertebrates, amphibians, or other flora and fauna which inhabit waters of the state at some stage of their life cycles. Generally, waters suitable for this classification have wetland characteristics, and such characteristics will be a primary indicator used in identifying Class 3 waters. There are three subcategories of Class 3 waters."l9

During the publications research phase of this review, a Wyoming Game and fish Department, Fish Division, Administrative Report titled" A Fisheries Survey of the Bitter Creek Drainage" authored by Bernard Carter in December 1993 was discovered. Given the significant impact this report will have on stream classification, a summary of that report follows. The full document, including tables and graphics, can be found in the appendix. No other documented fisheries data was found.

INTRODUCTION The Bitter Creek drainage is located in the of southwest Wyoming. The drainage consists of Bitter Creek proper, Salt Wells Creek, Gap Creek, Bean Springs Creek and Little Bitter Creek, as well as other ephemeral streams (Figure 1). There has been little inventory done of the system. In 1976 and 1977 some sampling was done in the drainage due to proposed mineral development. That sampling consisted mainly of species identification. The purpose of this survey was to determine species presence and abundance. Physical and chemical factors of the stream were also examined. Native species that have been documented in the drainage are mountain sucker (Catoslomu, platyrhynchus), bluehead sucker (Catostomus discobolus), flannelmouth sucker (Caloslomus commersolli) and speckled dace (Rhinichlhysosulus oseulus) (WY. Game and Fish, 1976- 1977: Baxter and Simon, 1970),

METHODS Stream sections were selected according to a change in habitat conditions, such as channel gradient and inflow. Sampling sites were chosen which were most representative of the habitat within the section (Figure 1). Areas where there are no sites

19 Historical Water Quality Repon Bitter I Killpecker Watersheds is due to no flow during the sampling period. Sampling was done between June and August 1993. Each sample site was approximately 300 feet in length. Data on wetted mean width, mean depth, velocity of flow, discharge (ds), and substrate composition were collected. Ten equally spaced transects were establlshed at each site. At each site, dissolved oxygen, total alkalinity, and total hardness were measured using an Ecology Combination Test Kit (model AI-36DT) produced by the HACH company. pH was measured with a VWR Scientific mini pH-meter (model 47) . Conductivity was determined using a Fisher Scientific digital conductivity meter.

Fish collections were by backpack electro-shocker. Both ends of the site were closed by a block net. Alter each pass all fish collected were measured and weighed. The fish were kept in a live well until all passes had been completed. The three-pass depletion method was used at each site. The data were entered in the River Station computer database. Due to the small size of the fish hand calculation had to be used to determine standing stock. Speckled dace, flannelmouth sucker and mountain suckers were the only native species found in the drainage. Both species were found in the tributaries to Bitter Creek. Non­ native species were fathead minnow (Pimephales promelas), white sucker (Catostomus commersoni), Utah chub (Gila atraria) and redside shiner (Richardsonius baltecus hydophiox). Species abundance (number per mile) is presented in Table 1 and standing stock (pounds per mile) in Table 2. Physical and chemical data are in Table 3.

Little Bitter Creek Site 1. 4484204019 Site 1 is at the headwaters, located about 4 miles below Maggie- Springs. This section is high gradient and clear flowing. The majority of the substrate was gravel and rubble. Banks were stable and the riparian zone was narrow. There was no evidence of grazing in the area this year, but there was evidence of past grazing. No fish were collected. This upper section of the stream may be suitable for introduction of Colorado River cutthroat trout. A food base of snails, caddis, stoneflies and beetles, were present in fair numbers. Before introduction, late summer flows and temperatures should be checked.

Little Bitter Creek Site 2. 4484204019 Site 2 is located at the lower end of the high gradient portion of the stream. The stream has done extreme down cutting of about eight feet. Inside the downcut bank stability was fair to good with 'the majority of the vegetation being rush grass. Vegetation was growing in the stream channel, showing that there may be periods of low flow in this section. Substrate was 70% silt (Table 3). No grazing had occurred this year but past grazing was evident. No fish were sampled, but one fish was seen one week later 200 feet above the site. Little Bitter Creek Site 3.4484204019 Site 3 is in an area were the stream comes out of the canyon (Site 2). The stream gradient (40 It/mi) is similar to Site 2, but the stream is wider (7.9 ft) and has a decreased velOcity (0.39 ft/sec). The stream is down cut about six to eight feet. The banks within the down cut are fairly stable with rush grass the primary vegetation. The substrate is 80% silt. Fathead minnows (FHM), mountain suckers (MTS) and speckled dace (SPD) were collected in site 3. FHM was the most abundant species with a population estimate of 6820 fish/mile. This was the highest population of FHM at any location. MTS (2923 fish/mile) and SPD (189 fish/mile) were also present. MTS had the highest standing stock of 49.4 lbs/mile.

Little Bitter Creek Site 4. 4484204019 Site 4 has similar characteristics to Site 3, width (6.9 ft), velocity (0.29 ft/sec) and gradient (35 ft/mi) (Table 3). The banks in the down cut were not as well stabilized as Site 3. There were areas of bare dirt and sloughing of the banks. The majority of vegetation was rush grass. FHM, MTS and SPD were all sampled, but in more evenly distributed proportions than at Site 3. FHM (574 fish/mile) and MTS (482 fish/mile) population decreased while SPD (519 fish/mile) increased. MTS had the highest standing stock of 13.0 Ibs/mile.

Little Bitter Creek Site 5.4484204019 Site 5 has decreased gradient (21 ft/mi), width (4.2 It), velocity (0.17 ft/sec) and flow (0.42 ft3) (Table 3). Later in the summer there may be no £low at this site. The banks were in poor condition with only spotty grass growth and were actively sloughing into the stream channel. There was a very large increase in the conductivity (3870) and total hardness (1448) from Site 4 (Table 3). Fish population decreased dramatically in Site 5. FHM (590 fish/mile) was the most abundant followed by SPD (166 fish/mile) and MTS (37 fish/mile). FHM and SPD had standing stocks of 1.8 and 1.61bs/mile respectively.

Salt Wells Creek Site 1. 4484017019 Site 1 is located approximately 4 miles below the springs that feed the stream. It is located above an irrigation diversion. The section is a high gradient (140 ft/mi) and high velOCity (1.06 ft/sec) stream (Table 3). The substrate was mostly gravel (89%). The banks are stable with rush, sedge and willows present. There were areas of the bank with no vegetation. No grazing had occurred at the time of sampling. No fish or aquatic invertebrates were sampled at this site.

Salt Wells Creek Site 2. 4484017019 Site 2 is located below the diversion. The flow (1.69 cts) was equivalent to Site 1, so it was assumed no water was being diverted at this time. Later in the summer there may be a considerable decrease in the flow due to irrigation. The site was very similar to Site 1. There was some algae growth in the stream channel which was not present in Site 1. There were no fish sampled at the site. Snails and caddis were observed. Flow decreased rapidly below Site 2 and no water was found approximately 15 miles below Site 2. There was additional flow where Gap Creek comes into Sal- Wells Creek. The flow was low and ceased approximately 4.0 miles from the confluence. No fish sampling was done at this location due to the closeness of Gap Creek Site 2 (Figure 1).

Bean Springs Creek Site 1. 4484019019 This site was located in the canyon just below the springs that feed the stream. The banks were in good condition with stable undercuts. Bank vegetation was dominated by sedge and rush grasses; willows were also present. The substrate was mainly gravel (69%). No grazing had occurred at survey time. Scuds, snails, caddis and stoneflies were sampled. No fish were collected. This section may be a good candidate for the introduction of Colorado River cutthroat trout, after further investigation.

Gap Creek Site 1. 4484017519 Site 1 is located below the confluence of Bean Springs Creek at Through Gap. Bean Springs Creek supplied all the water for Gap Creek at the time of sampling. There was no water found above the confluence with Bean Springs Creek. Velocity (0.45 ft/sec) had decreased considerably from the Bean Springs Creek (0.89 ft/sec) site. The width had also increased from 2.5 to 4.4 feet. The stream had down cut about six feet. The banks in the cut were fairly stable with sedge and rush grasses being the dominant vegetation. No grazing had occurred at the time of the sampling. SPD and MTS were sampled at this site. MTS had the highest population estimate of 7,059 fish/mile and highest standing stock of 71.3 lbs/mile.

Gap Creek Site 2. 4484017519 Site 2 was selected due to its decreased gradient (23 fI/mi) compared to Site 1 (104 ft/mi). The site is a halt-mile above the confluence of Salt Wells Creek. The banks were soft and unstable. The primary vegetation was rush grass, found on the banks and in the stream channel. Substrate was 100% silt. Fish population had decreased dramatically. A total of 28 fish were collected. FHM had the highest estimated population of 388 fish/mile and a standing stock of 2.3 Ibs/mile. SPD were also collected, with a population estimate of 84 fish/mile.

Bitter Creek Site 1. 4484200319 Site 1 is located at the head waters of Bitter Creek, below Fort LeClede. The banks are in fair condition with some down cutting of about one to two feet. The main vegetative growth is sedge and rush. Substrate was primarily gravel (75%). The gradient was fairly low (12 ft/mile). Discharge was 0.71 cfs. There had been no grazing at the time of the sampling but there was evidence of grazing in the past. Only native species were sampled at the site. SPD was the dominant species with an estimate of 6,062 fish/mile. MTS were also sampled, with a population estimate of 1,072 fish/mile. The stream bottom had little fine sediments, however there does not seem a possibility for introduction of Colorado River cutthroat trout due to water quality.

Bitter Creek Site 2.4484203019 Site 2 is located above the old town of Bitter Creek. The stream has had an increase in flow and down cutting activity. The banks are in fair condition with mainly rush grass. The stream bottom is very soft with 80% mud. The stream is wider than at Site 1. There were less fish sampled in Site 2 than Site 1. The majority of the fish were SPD, with an estimate of 2,042 fish/mile. MTS population estimate was 122 fish/mile (Table 2).

Bitter Creek Site 3. 4484203019 Site 3 is located at the upstream boundary of the Black Butte Coal mine. The stream is still down cut, but not as extreme as Site 2. The fiow had increased to 2.14 cfs. The banks were in poor condition with abundant sloughing. The majority of the bank vegetation was rush grass, with some willow present: There were areas of bare ground on the banks, but no grazing was present. MTS and SPD were coUected with the highest proportion being SPD (1,766 fish/mile). The MIS population (1,276 fish/mile) was not as high, but had a higher standing stock (26.7 Ibs/mile) than SPD (8.8 Ibs/mile).

22 Historical Water Quality Report Bitter I Killpecker Watersheds

Bitter Creek Site 4. 4484203019 Site 4 is located below Black Butte Coal mine. The stream flow had decreased to 0.64 cfs, but no correlation to the mine was made. Down cutting had continued with cuts of six to eight feet. The banks in the cut were in fair condition with some sloughing. The majority of the vegetation was sedge grass. There was an extremely high number of scuds observed in the section. Only 2 fish were collected in the site with both being SPO. The population estimate was 38 fish/mile. It seemed from the condition of the stream that more fish should have been present in the section. Further analysis may be needed to determine the cause of the decreased fish population.

Bitter Creek Site 5. 4484203019 Site 51 is located at the Point of Rocks Stage Station. The habitat was similar to Site 4. There was extreme down cutting, and bank instability. There was also a large number of scuds and snails observed in the section. Flow decreased below this site and within five miles there was no flow. There were more fish collected in Site 5 than in Site 4. Fish collected were SPO and MTS. Population estimates for SPO were 682 fish/mile and for MTS were 340 fish/mile. Standing stock was also higher for SPO with 6.3 lbs/mile compared to 4.9 lbs/mile for the MTS.

Bitter Creek Site 6. 4484203019 Site 6 is approximately 5 miles above the confluence of the Green River. The site is located below the Rock Springs city sewage treatment plant. This allows for a perennial flow. The stream at this site is much wider (23.5 ft) than the above sections. Conductivity was extremely high at 8500 mmhos, aJong with a high total hardness of 950. The banks were in good condition with a diverse vegetative community. There was a high concentration of algae growth in the stream channel. The fish community was more diverse than in the any other section of the drainage. This high diversity was thought to be due to the influx of fishes coming from the Green River. The highest population of fishes were the white sucker (WHS) at 1558 fish/mile and flannelmouth sucker (FMS) at 1,153 fish/mile. The majority 0' the FMS were immature fish. This may be an important nursery habitat for the FMS due to there listing of category IT under the Endangered SpeCies Act. The WHS had the highest standing stock of 54.2 lbs/mile. Other fish collected were speckled dace, fathead minnow, Utah chub, and redside shiner.

SUMMARY A total of five streams were sampled in the Bitter Creek drainage. The stream varied in size and structure. A constant variable was a progressive increase in alkalinity, total hardness and conductivity downstream. The upper portions of the streams were perennial, while lower sections were ephemeral. The upper sections typically had narrow channels and increased velocity (Photo 120 ). The lower sections usually had a wider channel with decreased velocity (Photo 12). Photo 16 is a picture of Bitter Creek below the sewage treatment plant. No correlation was found between any of the physical or chemical characteristics and fish abundance.

Fish populations were found in all tributaries to the Bitter Creek. Three native fishes were collected, speckled dace, flannelrnouth and mountain sucker. Speckled dace and mountain suckers were located throughout the drainage and seem to be well established. Flannelrnouth suckers were only sampled at Bitter Creek Site 6. Further investigation may be needed to detennine if the non-native fishes have any detrimental effects on the native fishes. Non-native fishes included fathead minnows, white sucker, Utah chubs and red sided shiner. All of the non-native fishes, except fathead minnows, were only collected below the sewage treatment plant. A few pools below Site 5 on Bitter Creek and above the town of Rock Springs were sampled and fathead minnows and speckled dace were collected. These pools may supply an environment for these fishes during periods of no flow.

ANECDOTAL INFORMATION Often when attempting to characterize the historical landscape of a watershed, anecdotal information can be used to supplement data obtained from electronic records and early written observations made in journals and periodicals. To attempt to obtain any additional historical information pertinent to the project the BKW AG developed a list of local citizens that may have possessed anecdotal information relevant to the project's goals and objectives. A list of 23 potential interviewees was developed. Numerous attempts were made to contact all of the people listed. Ultimately nine people were able to provide information related in some form to either Bitter Creek or Killpecker Creek.

Each person willing to be interviewed was asked the following seven project related questions, although some of those interviewed provided significantly more information about the past years in the Rock springs area than was relevant to the project. While that information was of gteat interest, it was outside the scope of this project and therefore is not included in the report. The general format for a majority of the interviews included seven questions that the interviewees would be asked. However, the manner in which the information was disseminated in answering those questions was not quite as structured. The transcription of those interviews follows, as close to the vernacular in which they were told:

Questions: 1. Would you be willing to discuss your memories and perceptions of Bitter Creek and Killpecker Creek? 2. How long have you lived in the Rock Springs area? 3. When you think of Bitter Creek, what is most prevalent in your memory? 4. When you think of Killpecker Creek, what is most prevalent in your memory? 5. Are there any other stories you may know related to either ofthe creeks? 6. Do you know of anyone else who may have relevant information? 7. Are there any books or articles that might contain relevant information that you would recommend?

Leonard Hay. Lifelong rest. 89 vrs) Rock Springs Area Res ident. Personal Interview Leonard ran 28 thousand sheep along the bitter creek. There were many springs in the Rock Springs area. Range condition has been improved. There is a high water table under Rock Springs (3-4 feet in some places). Stated that there where many mines under the town of Rock Springs. Once the mines closed and the pumping stopped the mines filled with water and the water table came back up. The mines were refilled to keep them from collapsing. South of town by "84 lumber" the water table is only 3-3112 feet down and seeps out through the washes. When mines used to pump out the mine water and put it directly into Bitter Creek, the children used to go and collect sulfur water once a month for medical purposes

Has photos of Bitter Creek being dry most of the year upstream of Rock Springs and maintains that Bitter Creek normally is dry above the town except during runoff but undergtound seepage from abandon mines keeps the creek flowing from Rock Springs downstream to the Green River. 1950's Leonard bought the wool warehouse and moved the creek. He used a mixture of 50% dirt and 50% ash from the mines to fill in the waterbed and rerouted the Creek along the base of the ridge. The Creek bed used to come out at National oil.

Bitter creek used to be a small town with and a school and a shearing shed that was built in 1919 by his (Leonard's) father. The town later burned down. They were unable to save the town as there was no water. At the town of bitter creek the Union Pacific RR used to pipe water to biner creek from Antelope Springs to fill the engines.

In 1860 Fort LeClede (at the headwaters of the watershed) was a stop for the pony express. Sections of the Fort can still be seen. Point of Rocks was al50 on the Pony Express route. 1886- 1887 was a tough winter with tons of snow.

1937 Biner Creek flood: Not long after the flood the Biner Creek channel was straightened out and widened through town, after you leave city limits the channel returns to its natural meander. Salt Wells Creek dam was put in before 1948. When the landoWner opens the gates it causes large cuts in the banks due to the force of the water.

Little Bitter creek was dry every summer and would only run during spring runoff or if there was a cloudburst. Killpecker Creek also mostly dry unless there was rain. Killpecker Creek is a natural streambed and was never channelized. About 10 miles up Kilipecker is Alkali Creek.

Alan Tominc. 53 year resident. Phone Interview Bitter Creek: In the 1950's his grandfather used to make sausages. He remembers as a boy going down under the bridge by End Street and cutting willows to hang sausages on. In the 1960's two large rain events caused flooding throughout the stream area and remembers the water being almost reaching the bottoms of the bridges through town. After the second rain event the city cleaned out the silt and removed all the willows from the banks in an attempt to stop the flooding. Since that time he notes that there is a lot less willows along the banks than he remembers as a child, he has noticed some areas are trying to come back. Stated that not to long ago (not sure when) beavers moved into Bitter Creek by the Belt Loop and began using all the trees the city planted to build dams. The beavers where trapped and removed from the area. He stated that if the city had just left the willows along the banks that the beavers would have used them for dams.

Killpecker Creek: Very putrid water. Never did any swimming in the water but remembers catching pollywogs and frogs. Only remembers one time (unsure of yr) that a summertime rain storm filled the creek. Didn't understand why we are looking for information on Killpecker Creek as it is empty pretty much all the time unless there is a major rain event.

Norma Ramsey. 50 year resident, Phone Interview Has no real memories of the water itself other than four of the families around her used to carry guns and fought over the water rights. Remembers people would steal water from them. Her ranch was burned out some time ago and the only thing that was saved from the fire was the original homestead. She stated again there is a war over the water rights and unless she keeps irrigating he!" place she could loose her water rights. Has leased the ranch to Dave Toman who is going to repair fences and irrigate for her. Have no memories of Killpecker Creek as it never really had water. Said we should be talking to Billy Logan as he is much older than her and could give more information. She told me that Billy is in the hospital and she will check on him to see how he is doing.

Wallv Johnson. 63 vear resident. Phone Interview. Wally felt that we should interview some of the older people in the area who could remember the people who lived in the walls of the banks of the creek, He felt he could only give us information that he remembered as a child. He was born and raised in #4, a coal miner town located east of Rock Springs and was separated from the town by Bitter Creek. All of the residents were miners and considered to be dirt poor. The children raised in the area considered Bitter Creek a large playground. As a child he remembers ice skating, hunting rabbits, and "hooking" trash wood that would float down the creek. Wally spent many years swimming in the creek and is still amazed that no one ever got sick, as the water was really bad. Stated that there was never fish in Bitter Creek. Wally remembers the Italian families making wine and when they were done they used to throw the "dregs" along the banks. He remembers how bad the area smelled from dregs laying along the banks.

frank Durnovich. Rock Springs Coal Miner since 1945. Personal Interview Lots of water in the mines, you always had to keep pumping to enable good working conditions. Water dripping down from the ceiling always turned the coal white. Blairtown residents used cesspools until mid-1940's when they hooked up to a storm sewer system. Did not recall ever seeing any fish in Bitter Creek.

Norman Hargis. Environmental Affairs Mana!!er. Bridger Coal Company. They have water quality data from 1983 for Deadman Wash and 10 Mile Draw. Periodic Flow and TSS with semi-annual DEQ suite for sediment control program. Also has detailed soils data for over 20,000 acres that should be indicative of what would be found in the remaining area of the watershed. Major concern is that their NPDES permit comes up for renewal in two years. Reclassification is a big issue to them. Bitter Creek used to be a class 4 and is now a class 2C (or B depending on who you talk to).

Mike Mevers. Cjvil Engineer. Jim Bridger Power Plant, Personal Interview Big influx of workers for the power plant in the early 1970's and they were living anywhere they could but mostly along Bitter Creek. No sanitary facilities. The Power Plant was completed in 1979 and by 1981 all of the workers had left. This coincides with a dramatic decrease in the fecal Coliform concentrations found in Bitter Creek at the Kanda sileo

Mille Radosevich. Blairtown resident for 80+ years, Personal Interview Always remembered the strong sewage smell from Bitter Creek.

27 Historic:!.1 Water Quality Report Bitter I Killpccker Watersheds

SUMMARY While limited in scope, recent water quality data indicates that there may be a seasonal fecal coliform issue in both Bitter and Killpecker Creeks in and below the Rock Springs area. Historical water quality data (> 10 years old) for Bitter Creek, and to a lesser extent Killpecker Creek, was significantly more accessible and indicated that the fecal coliform concentrations used to be much higher and widespread. Historic literature found in the development of this report also supported the premise that waste management in the Rock Springs area was not a priority for a number of years. It does appear that dramatic improvements have been made which have positively affected the current concentrations of fecal coliform in surface waters found within the Bitter Creek watershed. Additional data will be required however to definitively determine if it remains an issue, and if so, what can be done to reduce the concentrations of fecal coliform attributable to anthropogenic influences ..

Review of historical data related to chloride and its associated constituents does verify that chloride levels progressively increase in the water column as water passes through the watershed. However, diaries and journals from the mid-1800's (pre-settlement), written by trained"observers, engineers and surveyors passing through the area, describe surface water so saline that it could not be consumed safely. There is a strong correlation between chloride and saline conditions. Initially, given the observations from pre-settlement days, it appears that the waters in the Bitter Creek watershed may always have had elevated chloride levels in it's waters. Verification of the existence of the geological conditions that would naturally produce highly saline waters would require an assessment of the soils and sub-surface geology throughout the watershed.

Review of all available historical flow data for surface waters found in the BitterlKillpecker watershed, and the Wyoming Game & Fish Survey for the Bitter Creek drainage, when evaluated based upon the current WDEQ definitions of class 2C (warm water fisheries) and 38 (intermittent andlor ephemeral waters supporting aquatic life at some stage of the life cycle) streams, supports those classifications as currently written.
