In the Yuma area, Arizona, ground water is pumped mainly for the drainage of waterlogged land and for irrigation. In 1975 about 255,000 acre-feet of ground water was withdrawn, of which about 158,000 acre-feet was pumped for drainage of waterlogged land. For 1915-75, about 4,568,000 acre-feet was withdrawn, of which 2 ,387,000 acre-feet was pumped for drainage. Information shown on maps includes change in water level (1970-75) and irrigated area; depth to water and altitude of the water level; and specific conductance and fluoride concentration. A table of historical pumpage is included. (Woodard-USGS)
