Abstract
This potentiometric map is the second map of the lower Wilcox aquifer in a series of maps prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources, Bureau of Land and Water Resources, delineating the potentiometric surface of the major aquifers in Mississippi. The potentiometric surface of the lower Wilcox aquifer slopes generally to the west away from the outcrop area and it is marked by a large groundwater cone of depression in the area of Tallahatchie, Quitman, and Panola Counties. Water levels in or near the outcrop of the lower Wilcox aquifer show little longterm change. Heavy withdrawals in the downdip area have caused water level declines of about 1 to 2 feet per year since 1979 in much of the confined part of the aquifer. These water level declines in the area of Tallahatchie, Quitman, and Panola Counties have resulted in a wider cone of depression since 1979. (USGS)
