Datasets for the 2015 potentiometric surface and water-level changes (2011-2013, 2013-2015) in the Sparta-Memphis aquifer, in Arkansas

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-09-29T00:00:00Z
The groundwater-level change maps for the Sparta-Memphis aquifer are constructed as a point-to-point comparison between wells measured in both 2011 and 2013. Wells not measured in both 2011 and 2013 were not included in the change maps construction. The 2011-2013 change map contains 261 corresponding wells. Groundwater-level differences were calculated by subtracting 2011 groundwater-level measurements, in ft below land surface from the 2013 groundwater-level measurements, in feet below land surface.
