Natalie D. White R. P. Wilson Larry J. Mann 1978 The Willcox area includes about 1,500 square miles in southeastern Arizona. The main use of ground water is for irrigation. For 1954-75, the estimated ground-water pumpage exceeded 100,000 acre-feet per year, and for 1967-75, ground-water pumpage averaged about 300,000 acre-feet per year. Ground-water withdrawals have resulted in general water-level declines in most of the developed part of the area. Information shown on the maps includes change in water level (1963-75), irrigated area, depth to water, well depth, altitude of the water level, and distribution of dissolved solids and fluoride. Hydrographs of water levels in selected wells and a table of historical pumpage are included also.
