Maps showing ground-water conditions in the Agua Fria area, Yavapai and Maricopa Counties, Arizona

The Aqua Fria area includes about 1,500 mi 2 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 Ground-water development has been slight, and in 1978 about 3,200 acre-ft of groundwater was withdrawn; of this, about 2,200 acres-ft was used for irrigation, 600 acre-ft for public supply, and 400 acre-ft for domestic and stock supplies.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.

Maps showing ground-water conditions in the Hassayampa area, Maricopa and Yavapai Counties, Arizona—1978

The Hassayampa area includes about 1,300 square miles in west-central Arizona. The area consists of basins filled with alluvial deposits and mountains composed of crystalline and consolidated sedimentary rocks. The main water-bearing unit is the alluvial deposits, which consist of gravel, sand, silt, and clay. Other water-bearing units consist of crystalline and consolidated sedimentary rocks that may yield a few gallons per minute. In 1978 about 3,000 acre-feet of ground water was withdrawn from the area. Information shown on the maps includes depth to water, altitude of the water level, well depth, specific conductance, and fluoride concentration. Scale 1:125 ,000. (USGS)
