The Aqua Fria area includes about 1,500 mi2 in central Arizona. The area is bounded by the Prescott National Forest on the west, north, and east; by the Tonto National Forest on the southeast; and by the Bradshaw Mountains and Lake Pleasant on the southwest. Ground-water development has been slight, and in 1978 about 3,200 acre-ft of groundwater was withdrawn; of this, about 2,200 acres-ft was used for irrigation, 600 acre-ft for public supply, and 400 acre-ft for domestic and stock supplies. Public-supply use has increased nearly 30 percent (data in files of Arizona Corporation Commission Phoenix, Ariz.) Many small-capacity wells have been drilled in the area, and only selected areas are shown on the maps in areas of high well density.
