Map showing ground-water conditions in the Aravaipa Valley area, Graham and Pinal Counties, Arizona-1975

This hydrologic map of the Aravaipa Valley area includes about 500 sq mi in southeastern Arizona. Development of the ground-water resources is small, and pumpage is estimated to be less than 3,000 acre-ft annually for irrigation, livestock, and domestic uses. Hydrographs of the water level in selected wells show no long-term decline. Irrigation wells yield as much as 1 ,200 gal/min from the younger and older alluvium along Aravaipa Creek. The chemical quality of the ground water generally is good.
