. """ Q W ..(;:I.. .J . ANTICIPATED EFFECTS OF ADDITIONAL OEVELOPMENTS (continued) total of 150,000 acre-feet (185 x 106m3) depletion exclusive of Fon- tenelle evaporation is anticipated. Of this, an estimated 6,000 acre- feet C7 x 106m3) is planned for wildlife purposes while the remaining 144,000 acre-feet (178 x 106m3) of depletions was assumed to be for industrial purposes. Irrigation, however, may not yet be completely out of the picture. Industrial users include Pacific Power & Light Co., Sun Oil, and J'ossibly other industries. It is assumed the 6,000 acre-feet C7 x 106m3) of water for refuge purposes would neither pick up nor lose salts, but the remaining water for industrial purposes would deplete the salts as well as the water. The salinity concentration in the future at the Green River, Wyoming, gage would remain almost the same as at present because diversions to industries are anticipated to be located not too far above the gage. Private Industrial Rights. These for mineral development, particularly Total future depletions are expected to by the year 2010. rights are expected to be utilized for trona mining and processin~. reach 57,000 acre-feet (70 x 106m) 2. Between Green River at Green River, Wyoming, and Green River near Greendale, Utah Lyman Project. This is a multipurpose project located in southwestern 'vyarning. Project facilities consist of two dams and reservoirs. One is located at the Meeks Cabin site on the Blacks Fork in Wyoming and provides 33,000 acre-feet (41 x 106m3) of storage capacity. The other has been constructed at the State line site of the East Fork oE Smith Fork in Utah and will provide 14,000 acre-feet 07 x 106m3) of storage capacity. The project when completed will have the primary purpose of providing supple- mental water to 36,000 acres Os 000 ha) of existing fannhnd along with fish and wildlife and recreation benefits. This project will present an opportunity to study the water quality effects of adding supplemental water to lands already irrigated. Of the 10,000 acre-feet (12 x 106m3) total de- pletions, only 4,000 acre-feet (5 x 106m3) remain since 6,000 acre-feet (7 x 106m3) from Meeks Cabin Reservoir is now depleted. Utah Power & Light Co. This steam powerplant (Viva Naughton) is located at Kemmerer, Wyoming, with present depletions of about 6,000 acre-feet C7 x 106m3). Total future depletions of this plant are ex- pected to increase to 14,000 acre-feet (17 x 106m3 by the year 2000. 3. Above Yampa River near Maybell, Colorado Hayden and Craig Steam Powerplants. The addition of new units will require an estimated 20,000 acre-feet (25 x 106m3) of water by 1990. Present depletions amount to 10,000 acre-feet (12 x 106m3). It is assumed the plants will return no salt or water. 48
