Abstract:

The Gila River drainage from Painted Rock Dam to Texas Hill area includes about 3,000 square miles in southwestern Arizona. Ground-water development has taken place only in the northern part of the area, and only this part is included in the report. The southwestward-flowing Gila River drains the 1 ,900-square-mile northern part of the area. The main water-bearing unit is the valley-fill deposits. Since 1967, the estimated ground-water pumpage has exceeded 100,000 acre-feet per year, and in 1977 the ground-water pumpage was 210,000 acre-feet; the ground water is used mainly for irrigation. The ground-water withdrawals have resulted in general water-level declines in most of the area. Information shown on the maps includes change in water level, 1965-78 and 1973-78, and irrigated area; depth to water, altitude of the water level, and well depth; and specific conductance and fluoride concentration in the water. Hydrographs of the water level in selected wells and a table of historical pumpage also are included. Scale 1:250 ,000. (Kosco-USGS)
