Potentiometric surface dataset of the Sparta-Memphis aquifer in Arkansas, January 2013 - May 2013 (ver. 1.2, June 2021) The U.S. Geological Survey (USGS), in cooperation with the Arkansas Natural Resources Commission, Arkansas Geological Survey, and the Union County Water Conservation Board, has monitored water levels as a part of an ongoing effort to provide information for management of the Sparta-Memphis aquifer. The USGS has produced reports, at various intervals, to describe groundwater conditions in the Sparta-Memphis aquifer. These datasets provide the locations of and groundwater-level altitudes from 306 wells that were used to construct a potentiometric contour surface of the Sparta-Memphis aquifer. Measurements were made from January through May 2013 and represent synoptic conditions. All wells were cased completely in...
