Arizona Water Resource October-December 1981

Groundwater withdrawals in Arizona in 1978 and 1979 were, with one exception, the smallest in over twenty-five years. According to a recent U.S. Geological Survey report prepared in cooperation with the Arizona Department of Water Resources, about 4.0 million acrefeet of groundwater was withdrawn in Arizona in 1979, which is about 200,000 acre-feet less than the amount withdrawn in 1978. The withdrawals in 1978 and 1979 are the smallest since the mid-1950's, with the exception of 1966.
