Show Dike to keep high waters of Utah Lake from encroaching on lower lands of the Beer Creek portion of the Spanish Fork area. It would also include drainage pumping plants near Beer Creek and in the Provo Bay area to pump drainage water to Utah Lake. A deep drainage well in the Elberta subarea would be provided to protect lower- lying non- Unit lands. Water from the well could be used for irrigation of Bonneville Unit lands if it is found to be of suitable quality. Existing subsurface drainage systems in the Sevier River areas would be adequate to protect the Unit lands under present water supplies and with the small amount of water to be provided by the Bonneville Unit. Therefore, no Unit drains are planned for the Sevier River areas under the Bonneville Unit. Other areas that do not appear to require subsurface drains under the Bonneville Unit are the Heber- Francis and the Peteetneet areas. e. Municipal and Industrial Water System The Municipal and Industrial Water System ( Fig. A- 26) would include Jordanelle Reservoir on Provo River; improvement of the existing Provo Reservoir Canal; the Jordan Aqueduct; the Alpine Aqueduct; and Lampton Reservoir on Jordan River, which would reregulate Bonneville Unit return flows below Utah Lake. Most of the municipal and industrial water supply which would be stored and regulated in Jordanelle Reservoir would be salvaged from Utah Lake by reducing the evaporation. Diking of Utah Lake ( Provo and Goshen Bays; would reduce the surface area of the lake by about 35 percent and would result in an evaporation savings of more than 1059000 acre- feet of water annually. Part of this savings would be exchanged upstream in Jordanelle Reservoir for Provo River water that presently flows into Utah Lake. As required for municipal and industrial use, the stored water would be released to the Provo River, and thence diverted to Alpine Aqueduct or to Jordan Aqueduct via Provo Reservoir Canal. Municipal and industrial water developed by the Unit would total 99,000 acre- feet, to be distributed as follows: Salt Lake County, 70,000 acre- feet; northern Utah County, 20,000 acre- feet; southern Utah County, 7> 500 acre- feet; and Juab County, 1,500 acre- feet. Storing surplus flow from the Jordan River, spills from Utah Lake, and Bonneville Unit return flows, Lampton Reservoir would provide water for industrial development in Salt Lake Valley. The distribution works required to deliver this industrial supply have not been determined. 89 |
