Datasets for the 2015 potentiometric surfaces and changes in groundwater levels (2009-2015), in the Cockfield (upper Claiborne) and Wilcox aquifers, in northeastern and southern Arkansas

Datasets includes groundwater well locations and 2015 water-level measurements for 31 wells, 20-foot contours, and water-level change for 31 wells measured in 2009 and 2015 of the Cockfield (upper Claiborne) aquifer. Data also includes groundwater well locations and 2015 water-level measurements for 37 wells, 10-foot contours of the northern Wilcox aquifer, 20-foot contours of the southern Wilcox aquifer, and water-level change for 31 wells measured in 2009 and 2015 of the Wilcox aquifer. Rasters for each aquifer were also constructed. Well-location and water-level data are publicly available from the U.S. Geological Survey's National Water Information System, April through June 2015 (U.S. Geological Survey, 2016).
