Daphne Darden 1986 This map, the second in a series for the Cockfield aquifer in Mississippi, follows a map that delineated the 1980 potentiometric surface of the aquifer. This water level map is based on water level measurements made in about 80 wells in the Cockfield aquifer in the fall of 1984. The contours show altitudes at which water levels would have stood in tightly cased unpumped wells in fall 1984.
