Abstract

The 1980-81 drought resulted in the lowest rates of streamflow since 1954 in most areas of Georgia, and the lowest since 1925 in some areas. Over most of the State, minimum average streamflows for periods of 1, 7, 30, 60, 90, and 183 consecutive days receded to low levels estimated to be reached at average intervals of 10 to 25 years. Flows in the Flint River from central to southwest Georgia receded to levels estimated to be reached at average intervals of 70 years. Pool levels at four major reservoirs receded to the lowest levels since the reservoirs were first filled. Ground-water levels declined below the lowest levels previously observed in many observation wells. Nearly continuous declines were recorded in some wells for as much as 20 consecutive months, and levels remained below the previous minimum level of record for as much as 9 consecutive months.
