Chart showing long-term groundwater levels in a well in Georgia, 1966 to 2004.

Detailed Description

Chart showing monthly-mean water levels from 1964 to 2003 for a well in Cook County, southwest Georgia. The well is used for irrigation and public-supply purposes and offers a good visual representation of long-term groundwater declines due to excessive pumping. Periods of drought also have an effect on groundwater levels, as replentishing water infiltrating into the aquifer would be reduced.
