Sparta-Memphis aquifer water level altitude contour dataset in Arkansas, January-May 2013 (ver. 1.2, June 2021)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-09-29T00:00:00Z
This dataset contains 20-ft contours for the 2013 Sparta-Memphis aquifer potentiometric-surface map in Arkansas. The potentiometric-surface shows altitudes at which the water levels would have risen in tightly-cased wells and represents conditions during the period from January through May 2013. Groundwater-level data from 306 wells cased completely in and with the screened interval open to the Sparta-Memphis aquifer are publicly available from the U.S. Geological Survey’s National Water Information System.
