PART VI FUTURE DEVELOPMENT e n. White River Dam Evaporation from the White River Reservoir is estimated to be 5,500 acre-feet, rounded to 6,000 acre-feet. It was assumed that the dam will be in place by 1990. o. Oil Shale Present plannlng indicates that the White River Dam and Reservoir may be capable of yielding up to 75,000 acre-feet of water annually. Projections of water use for the oil shale industry are down considerably from projections made 2 years ago. Values shown through the year 2010 were supplied by the Utah Division of Water Re- sources. It should be realized that all of the projected oil shale depletion values contain a high degree of uncertainty. p. Tar Sands e In November 1983, the Bureau of Land Management issued a Draft Environmental Impact Statement describing, development alterna- tives for special tar sand areas in Utah. Two development alternatives were presented--high commercial production and low commercial produc- tion--which would result in 88,295 and 22,200 acre-feet per year of depletion, respectively, by the year 2005. The Utah Division of Water Resources has requested that for purposes of Table A a level of develop- ment midway between the low commercial and high commercial production scenarios be assumed through the year 2010, which results in the numbers shown. B. Lower Basin Depletions Estimates of future consumptive use by Lower Basin States of main stem Colorado River water were derived from (1) quantities recommended by the Decree of the Supreme Court of the United States in Arizona vs. California (March 9, 1964) and (2) lists of present perfected rights filed with the court. Rates of development have been estimated in those cases where a particular use is not yet fully developed. Certain other exist- ing uses are presumed to be curtailed when the Central Arizona Project becomes fully operational (assumed to be in 1988). In California, the Seven Party Agreement (August 18, 1931) also serves as a basis for esti- mates of future ~se within that State. 1. Nevada a.
