Show water sources in the Jordan River Basin is completed, approximately 348,360 acre- feet of water will be available annually on a reliable basis to meet public water needs ( see Table 9- 2). Of this total, 125,410 acre- feet is from groundwater sources, 5,800 acre- feet from artificial groundwater recharge, 61,850 acre- feet from local mountain streams, 61,700 acre- feet from Deer Creek Reservoir, 84,000 acre- feet from CUP, and 9,600 acre- feet from the Welby/ Jacob Exchange. Little Cottonwood Water Treatment Plant, Metropolitan Water District of Salt Lake City Salt Lake City has acquired an annual average water supply of approximately 167,000 acre- feet. This includes 61,700 acre- feet of storage in Deer Creek Reservoir controlled through the Metropolitan Water District of Salt Lake City. In addition, Salt Lake City obtains an average of 68,000 acre- feet each year from mountain streams, 20,000 acre- feet from the CUP, and 17,600 acre- feet from springs and wells and additional small quantities of water from miscellaneous sources. Salt Lake City's water supply can be characterized as " firm". The SLCWCD has a firm water supply at the present time of 98,600 to 102,800 acre- feet. In addition to the water it directly controls, the district has an agreement with the MWD ( subject to availability) for an annual 10,000 acre- feet of treated Deer Creek Reservoir water. This 2-; agreement is valid through the year 2001, and may then terminate. Water from the MWD has been sufficient in most recent years to meet Salt Lake City needs and fulfill conditional commitments to the SLCWCD, but continued growth in Salt Lake City service areas will reduce water currently delivered to SLCWCD. With this in mind, the SLCWCD has developed plans for other sources of water. The district's current supply of about 100,000 acre- feet should provide an adequate supply through the year 2010. Beyond that time SLCWCD intends to develop 25,000 acre- feet through conversion of Utah Lake irrigation water in Salt Lake County along with a. major treatment plant expansion and improved treatment processes. The SLCWCD also expects to develop 50,000 acre- feet of Bear River water by the year 2015 as part of a state- sponsored Bear River project. It is anticipated that another 25,000 acre- feet of Utah Lake water will be converted to municipal use sometime after the year 2015. 2.12 Water Quality This section presents data and information on existing levels of water quality in the Jordan River Basin. Sources of pollution are identified, problems and solutions are discussed, and recommendations for control and improvement by responsible agencies are given. The 44- mile stretch of the Jordan River from the outlet of Utah Lake to the Great Salt Lake is currently used for recreational, industrial, agricultural and wildlife purposes. The Jordan River represents a tremendous potential for even greater usage in all of these areas, as well as a potential source for domestic water, if the water quality could be improved to acceptable standards. It is generally acknowledged that water flowing from Utah Lake is of poor quality. Water quality data collected for the Jordan River, however, shows water quality continues to be degraded as the river makes its way through the Salt Lake Valley en route to the Great Salt Lake. At the present time, the basin has five wastewater treatment plants( WWTP). Four are public facilities. The fifth, privately owned and operated by Kennecott Corporation, is a self- contained facility. South Valley WWTP discharges directly to the Jordan River while Central Valley WWTP discharges to Mill Creek just above its confluence with Jordan River. The other two treatment plants, Salt Lake City WWTP and Magna WWTP, discharge almost directly into the |
