Show estimated to be around 134,500 acre- feet per year. An estimated 145,800 acre- feet of the present 174,300 acre- feet of existing groundwater supply is suitable for culinary use without treatment. The remaining 28,500 acre- feet is of lesser quality ( high salinity, i. e., high total dissolved solids) and suitable for culinary use only after treatment to lower the salinity or after blending with higher quality water. Water quality is discussed in more detail in Section 12, Water Quality and Section 19, Groundwater.

These development plans are discussed in more detail in Section 9, Water Planning and Development. But restrictions are currently imposed by the State Engineer on applications to appropriate new groundwater. These restrictions, discussed in greater detail in Section 19, Groundwater, essentially close the county to new groundwater applications. 5.3.3 Imported Water Salt Lake City can import as much as 61,700 acre- feet of water from the upper basin. This water is delivered from Deer Creek Reservoir through the Salt Lake Aqueduct and conveyed primarily to the MWD water treatment plant. The Central Utah Project ( CUP) currently delivers 20,000 acre- feet of municipal and industrial water to the Jordan River Basin. With the completion of Jordanelle Reservoir and other Central Utah Project elements, the CUP is now capable of delivering an annual average of 70,000 acre- feet. The Central Utah Project will be managed, however, to bring up to 84,000 acre- feet into the basin during times of drought. The Welby- Jacob Exchange of Utah Lake water for higher quality Provo River water provides an average annual supply of 29,400 acre- feet. The Big Cottonwood Creek 5- 6 |
