2b_2015 Wilcox aquifer contour dataset, in northern Arkansas

Dataset contains 10-foot contours for the 2015 Wilcox aquifer potentiometric-surface map in northern Arkansas. The potentiometric-surface map shows altitudes at which the water levels would have risen in tightly cased wells and represents conditions between April through June 2015. Groundwater-level data from 29 wells located in northern Arkansas cased completely in and with the screened interval open to the Wilcox aquifer are publicly available from the U.S. Geological Survey’s National Water Information System.
