SUBJECT: Appendix N
Surface Water Quality

PREPARED BY: Bear River Basin Planning Team

Introduction

The purpose of this memorandum is to identify and summarize surface water quality issues within the State of Wyoming's portion of the Bear River basin. Ground water quality issues are discussed in a separate memorandum.

Water quality issues within the Bear River basin are monitored by a number of organizations and committees. One of these organizations, the Bear River Basin Water Quality Task Force has been instrumental in the coordination of water quality work within the tri-state (Idaho, Utah, and Wyoming) basin. The Bear River Basin Water Quality Task Force was organized in 1993 by the Bear Lake Regional Commission, the Bear River Resource Conservation and Development Council, the Western Wyoming Resource Conservation and Development Council, and other government agencies and citizens interested in the Bear River basin's water quality issues. The goals of the Task Force are:

to improve water quality of the Bear River and its tributaries, lakes and reservoirs in order to meet the designated use(s) of the water, and
to coordinate a tri-state water quality planning approach incorporating local involvement.

The Task Force coordinates water quality planning issues with the appropriate regulatory agencies for each state. The primary regulatory agency that manages water quality issues within Wyoming is the Water Quality Division (WQD) of the Wyoming Department of Environmental Quality (DEQ). The WQD oversees many of the water quality protection programs within Wyoming, including programs relating to point source (PS) pollution and non-point source (NPS) pollution, and the potential impacts on both surface water (SW) and ground water (GW) sources. A list of the programs regulated by the WQD is found in Attachment A of this memorandum. Attachment A also includes programs effecting water quality issues in Wyoming that are regulated by federal agencies (programs in which the state does not have primacy). The U.S. Environmental Protection Agency (EPA) empowers states to oversee their own environmental regulatory programs, so long as they meet or exceed the expectations of the federal government.

Water Quality Standards

Surface Water: The WQD developed water quality standards, which are documented in Chapter 1, Wyoming Water Quality Rules and Regulations. Chapter 1 can be downloaded from http://soswy.state.wy.us/rules/search.htm. [new link 10/2009 http://deq.state.wy.us/wqd/WQDrules/Chapter_01.pdf] The surface water quality standards are divided based on four different surface water classifications:

Class 1 surface waters are designated by the Environmental Quality Council based on water quality, aesthetic, scenic, recreational, ecological, agricultural, fish and wildlife, and other factors that contribute to the present and future value of the water body to the people. No further water quality degradation by point source discharges other than from dams will be allowed in Class 1 waters. Best management practices will be implemented to control non-point source pollution.
Class 2 are surface waters, other than Class 1, that either presently support game fish or have the hydrologic and natural water quality potential to support game fish, or contain nursery areas or food sources for game fish.
Class 3 are surface waters, other than Class 1, that either presently support nongame fish only or have the hydrologic and natural water quality potential to support nongame fish only, or contain nursery areas or food sources for nongame fish only.
Class 4 are surface waters, other than Class 1, that do not have the hydrologic or natural water quality potential to support fish. This includes intermittent and ephemeral streams.

These classes can be found in Section 4 of Chapter 1. Appendix A of the WQD Wyoming Water Quality Rules and Regulations report contains the classification listing of all surface waters organized by basin. Appendix B of the WQD report lists the Water Quality Criteria for Priority and Non-Priority Pollutants. This list is categorized by Aquatic Life Acute Value, Aquatic Life Chronic Value, and Human Health Value. According to Section 18, Chapter 1, the Human Health Value shall not be exceeded in Class 1, and Class 2 waters. The Aquatic Values shall not be exceeded in Class 1, 2 and 3 waters. Class 4 waters receive protection for agricultural uses and wildlife watering. The current stream classifications for the Bear River Basin are shown in Figure 1 of this memorandum.

Interstate Water Quality Standards: The Bear River flows through three states; Idaho, Utah and Wyoming, and is administered through the Bear River Compact. This compact serves as an administrative tool for the three states and divides the basin into three divisions. Part of both the Upper and Central Divisions fall in Wyoming. Each state regulates their respective divisions water quality programs, which can either be administered by the state or by EPA. The Wyoming basin is administered by the state through the water quality standards described in the above section on Water Quality Standards.

Basin Surface Water Quality

The United States Geological Service (USGS) has four water quality monitoring stations located within the Wyoming portion of the Bear River Basin that have significant historical water quality data sets as shown in Table 1. Note that all of these stations, except station 10020100, fall within the central division of the Bear River Compact. The locations of these stations are shown in Table 1.

Total dissolved solids (TDS) is a measure of the total amount of dissolved salts in water. Conductivity is the measure of a waters ability to conduct electricity. As the amount of dissolved salts in water increases, the number of ions increases, and hence the conductance increases. TDS is commonly derived from conductance measurements by multiplying the specific conductance by 0.6. Because it is easily measured by taking either specific conductance or TDS measurements, TDS is frequently used as an indicator of overall water quality.

Seasonal and flow based trends of TDS were plotted for the four USGS gages listed above. The EPA set a TDS standard in the Safe Drinking Water Act of 500mg/L for drinking water. No TDS criteria exists in Appendix B of Chapter 1, Wyoming Water Quality Rules and Regulations, but we understand that the surface water quality standard follows the same criteria that is set forth in the ground water quality standards. These standards are shown in Table 2.

TABLE 2

Pollutant Standard according to Groundwater Classifications

Domestic Agricultural Livestock

Total Dissolved Solids 500 mg/L 2000 mg/L 2000 mg/L

TABLE 2
Pollutant	Standard according to Groundwater Classifications
Domestic	Agricultural	Livestock
Total Dissolved Solids	500 mg/L	2000 mg/L	2000 mg/L

The following Figures 2 through 6 show that, in general, the TDS decreases with an increase in flow. This expected trend can be attributed to the source of water during different flow regimes. In the late spring and early summer, much of the flow is direct runoff from snow melt. In the late summer and non-irrigation months, much of the flow is agricultural and municipal return flows. These return flows are generally higher in TDS due to both man's influence and naturally occurring constituents in the soil.

Figure 2

As shown in Figure 2, Twin Creek consistently exceeds the TDS standard for domestic use, but only exceeds the agricultural and livestock standard once in a sixteen year period (1975-1981 and 1989-1999). The primary use of lands in the Twin Creek drainage basin is for livestock grazing. If we consider the livestock water quality TDS standard as being the correct classification of Twin Creek, then TDS is not an issue. The most probable reason that TDS is higher in Twin Creek than in any other recorded segment of the Bear River basin, is due to the highly erodible shales at Twin Creek's headwaters, which contribute carbonate and salts into the drainage.

Since Twin Creek has the highest concentration of TDS in comparison to the other water quality gages in the Bear River basin, other water quality parameters at Twin Creek were studied when available. Eighteen dissolved manganese samples and 63 total nitrogen samples have been taken over the study period at the Twin Creek gage. Only two of the dissolved manganese samples are at the 50 mg/L limit for dissolved manganese as set by the Safe Drinking Water Act. All of the total nitrogen samples are lower 4 mg/L, which is far below the standard of 10 mg/L, as set in Wyoming's water quality standards for stream classifications 1 and 2. By analyzing TDS and the two additional parameters at Twin Creek, it is apparent that no water quality concerns exist for the parameters with available data.

Figure 3

Figure 5

Figure 6

The remaining four USGS gages are all consistently below the domestic use standard of 500 mg/L as seen in Figures 3 through 6.

Note that all but one of the USGS gages with a longer period of water quality records are in the Central Division of the Bear River basin within Wyoming. The Upper Division has less frequent spot samples along the Bear River and, as expected, show even lower TDS values. Figure 7 shows the average TDS for the available data from the Bear River above Reservoir downstream to the Bear River below Smith's Fork and then further downstream to Border.

Figure 7

As expected, TDS increases from the Bear River above Reservoir gage to the Bear River below Smith's Fork gage, or upstream to downstream, reflecting the use, return, and reuse of the available resource. The reach from the Bear River below Smith's Fork to Border, is less than eight river miles with little development, and this is reflected in the TDS concentrations, which remain relatively constant between the two gages. Using the Bear River at Border gage as an example, Figure 8 shows that the amount of TDS measured at this gage has been relatively constant over the study period, and indicates that degradation of water quality is not a concern at this location.

Figure 8

Total Maximum Daily Loads / 303 (d) List

Total Maximum Daily Loads (TMDLs) are the amounts of pollutants a waterbody can receive and still maintain its designated uses. TMDLs are required to be established for each pollutant that is contributing to the impairment of a waterbody. Development of TMDLs must consider both point source and non-point source pollution and additionally must account for natural background conditions.

Section 303(d) of the Clean Water Act requires States to:

identify all the waters in the State which are impaired (water which cannot meet it's designated use),
prioritize all impaired waters for the development of TMDLs based on public health and environmental risk,
and establish and adopt TMDLs for all impaired waters or for all waters that would be impaired if a TMDL was not established.

This list must be reported by the States every two years. Appendix B of the year 2000 303(b) State Water Quality Assessment Report from Wyoming includes the 303(d) list. Within the Bear River Basin, Bridger Creek was listed as a waterbody with water quality threats. Bridger Creek flows through Wyoming and enters the Bear River in Utah, downstream of the town of Randolph.

A study in the early 1990's determined that Bridger Creek was a significant contributor of sediment and phosphates to Bear River. As a result of this study, a watershed improvement project was completed in 1996 and has significantly reduced loading. However, Bridger Creek remains on the 303(d) list because of potential impairment of aquatic life use support. The impairment on Bridger Creek was indicated as physical degradation due to non-point source pollution, and was listed as a low priority for developing TMDLs as seen on Table C of the 303(d) list. Two waterbodies within the Bear River Basin were delisted from the 1998 303(d) list; Yellow Creek below the Evanston Waste Water Treatment Plant, and the Bear River below the Cokeville Waste Water Treatment. These waterbodies were delisted due to the implementation of ammonia, fecal coliform and total residual chlorine TMDLs for Yellow Creek, and the implementation of fecal coliform and total residual chlorine TMDLs for the Bear River.

Conclusions

Given the available data sets, the Bear River basin has no significant water quality issues as seen at the five USGS water quality gages.

The primary use of water in this basin is for agricultural purposes, and when the data available for TDS and other parameters is compared to standards set for agricultural use, concentrations are consistently below the water quality limits.
With the exception of Twin Creek, all the gages have TDS concentrations consistently below the TDS standards set for drinking water limits.
It is also apparent that the concentrations of TDS vary with flow. During low flow seasons, such as late summer months and non-irrigation seasons, the concentration of TDS increases, likely due to agricultural and municipal return flows. During high flow seasons, such as late spring and early summer months, TDS concentrations decrease.
Throughout the study period for the USGS water quality gages, no significant increase has been seen in TDS concentrations, indicating a relatively stable environment.
