About 80 percent of the reservoir storage, which <br />is principally for regulation of streamflow, would be constructed in the Bear River <br />and Great Salt Lake subregions. None would be constructed in the Tonopah sub- <br />region. Nearly all of the canals, tunnels and aqueducts would be constructed in the <br />eastern subregions. <br /> <br />FACILITIES PLANNED TO DEVELOP THE REOUIRED WATER SUPPLY <br /> <br />1965 1980 2000 1965 <br />to to to to <br />Type of Facility Unit 1980 2000 2020 2020 <br /> <br />Total surface water storage 1000 A.F. 1,600 981 700 3,281 <br />Conservation water storage' 1000 A.F.

This permits meeting a substantial part of the projected depletion <br />requirements without additional new diversions. Part of the additional depletion re- <br />quirements for waterfowl habitat will be met by improved management. Additional <br />diversions are required only to supplement the natural supply. Further development <br />of smaller streams and ground water, and more widespread water reuse practices will <br />also be important in meeting projected water requirements. <br />Land use changes were projected to continue as indicated by past trends, and <br />competition for certain uses will increase. For example, urban and industrial land <br />
