sand areas in Utah. Two development alternatives were presented-high commercial production resulting in 22,200 acre-feet per year and low commercial production resulting in 88,295 acre-feet of depletion by the year 2005. Current estimates do not anticipate utilization until after 2030. LOWER BASIN DEPLETIONS Depletions described in this section include only those needed for Colorado River Simulation System (CRSS). The depletions are only for the mainstem of the Colorado River in the Lower Basin. Estimates of future consumptive use by Lower Basin States of mainstem Colorado River water were derived from: (1) quantities recommended by the decree of the Supreme Court of the United States in Arizona v. 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 becomes fully operational. In California, the Seven Party Agreement (August 18, 1931) also serves as a basis for estimates of future use within that State. Nevada Robert B. Griffith Water Project-In 1993, the project diverted approximately 295,000 acre-feet of Colorado River water for municipal and industrial uses and consumed about 172,000 acre-feet. The project delivers water to Las Vegas Valley Water District, Nellis Air Force Base, and the cities of North Las Vegas, Henderson, and Boulder City. Non-Griffith Project Water Users above Hoover Dam-The users above Hoover Dam not from the Griffith Water Project include Basic Management Inc., the city of Henderson, Pacific Coast Building Products Inc., Boulder City, Lake Mead Recreation Area, and diversions at Hoover Dam. Total uses of such water were 16,500 acre-feet in 1993. Mohave Generating Station, Southern California Edison Company-Prior to March 1, 1993, a portion of Nevada's allotment for use by the station was obtained via contractual arrangements by the Southern California Edison Company. These arrangements permitted the diversion of up to 23,000 acre-feet annually from the Colorado River for thermal power production purposes at the generating station site about 3 miles downstream from Davis Dam. These contractual arrangements were altered, effective March 1, 1993, so that the generating station, which continues to be separately metered, receives Colorado River water out of the entitlements of the Southern Nevada Water Authority. In 1993, about 14,800 acre-feet were diverted to the Southern California Edison facility from the Colorado River below Davis Dam. Fort Mohave Indian Reservation-There are 1,939 acres of Fort Mohave Indian Reservation land located in Nevada. In 1993, no water was diverted to these lands. It has been estimated that the portion of the reservation located in Nevada will use approximately 2,000 acre-feet by 2000 and 8,000 acre-feet by 2020. 37
