Of said water so appropriated approximately 2,500,000 acre feet are diverted annually from the Colorado River above Lees Ferry and from tributaries entering said river above that point and are used and consumed in Utah, New Mexico, Colorado and Wyoming; and 3,600,000 acre feet are diverted annually below Lees Ferry and from tributaries, other than the Gila, entering said river below Lees Ferry and are used and consumed as follows: Arizona .................................................... 585,000 California ................................................2,475,000 Mexican Republic.................................... 500,000 Nevada .................................................... 40,000 Non-diversion river losses between Boulder and Imperial Dams plus evaporation from Boulder and Parker Reservoirs will aggregate 1,400,000 acre feet annually and about offset the river's gains between Lees Ferry and Boulder Dam. Of the virgin flow of the Gila in the Phoenix area, 2,885,000 acre feet per year have been used and appropriated in Arizona and 15,000 in New Mexico.
