42 Chapter 6-Present and Future Development 6,000 acre-feet. It was assumed that the dam will be in place by 2010. 011 Shale Present planning 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 in the early 1980's. Values shown through the year 2010 were suggested by the Utah Division of Water Resources. Tar Sands In November 1983, the Bureau of Land Management issued a draft environmental impact statement describing development alternatives for special tar sand areas in Utah. Two development alternatives were presented-high commercial production and low commercial production-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 recommended the numbers shown. LOWER BASIN DEPLETIONS Depletions described in this section include only those needed for CRSS. The depletions are only for the main stem of the Colorado River in the Lower Basin. 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 existing uses are presumed to be curtailed when the Central Arizona Project will become fully operational by the mid 1990's. In California, the Seven Party Agreement (August 18, 1931) also serves as a basis for estimates offuture use within that State. Depletions projections for 1990 presented in table 3 were estimated in 1989. Nevada Las Vegas Valley The Las Vegas Valley consumed about 93,255 acre-feet of municipal and industrial water in 1987 and includes diversions from the Basic Management, Inc. (BMI) pipeline and the Robert B. Griffith (RBG) water project. The latter project delivers water to Las Vegas Valley Water District, North Las Vegas, Henderson, and Nellis Air Force Base. The BMI pipeline serves municipal water to the city of Henderson and BMI in Henderson. Boulder City Boulder City's maximum allowable diversion from the Boulder City Act of 1958 is 3,650 gal- lons per minute or 5,890 acre-feet per year. In the next few years, Boulder City is expected to establish an entitlement to an additional 11,000 acre-feet of water from Lake Mead under the Robert B. Griffith Project. In 1987, Boulder City diverted about 6,300 acre-feet from RBG and less than 50 acre-feet from its older, separate, federally constructed system. Lake Mead Recreation Area The Lake Mead Recreation Area is entitled to that quantity of water that is reasonably necessary to fulfill the purpose for which the recreation area has been set aside. In 1987 about 906 acre-feet were diverted to the recreation area from Lake Mead. It is also projected that 1,000 acre-feet will be diverted to the area annually through the year 2010. Miscellaneous Users Above Hoover Dam Two corporations have contracts pennitting diversions of 1,048 acre-feet per year of Lake Mead water. In 1987, only 572 acre-feet were diverted. It was projected that 928 acre-feet, on the average, will be consumed through the year 2010.
