Dataset contains the groundwater well locations and water-level measurements for 273 wells measured during a water-level survey of the Sparta-Memphis aquifer in Arkansas, January through June 2015. Well-location and water-level data is publicly available from the U.S. Geological Survey's National Water Information System.

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.

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...

Dataset contains 20-ft contours for the 2015 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 June 2015. Groundwater-level data from 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.

These datasets provide the locations of and groundwater-level altitudes from 273 wells that were used to construct a 2015 potentiometric contour surface of the Sparta-Memphis aquifer. Measurements were made from January through June 2015 and represent synoptic conditions. All wells were cased completely in and screened in the Sparta-Memphis aquifer. Groundwater-level data are also available from the USGS National Water Information System (U.S. Geological Survey, 2017). The groundwater-level change maps for the Sparta-Memphis aquifer are constructed as a point-to-point comparison with wells measured in both 2011 and 2013 and both 2013 and 2015. Wells not measured in both 2011 and 2013 and both 2013 and 2015 were...
This dataset includes isopach contours showing altitude of freshwater of the Carrizo-Wilcox aquifer, control points used to construct the freshwater isopach contours, isopach contours showing altitude of top of the Carrizo-Wilcox aquifer, wells used to construct cross sections and isopach contours, hydrogeologic cross section H-H' through S-S' lines, isopach contours showing altitude of the base of the Carrizo-Wilcox aquifer, well points used to construct base isopach contours, isopach contours showing thickness of the Carrizo-Wilcox aquifer, and wells used to construct thickness isopach contours. Datasets are shown in figures of the larger body of work "Hydrogeologic framework of the Red River alluvial aquifer...
This dataset includes the surficial extent of the Red River alluvial aquifer, cross-section wells within the Red River alluvial surficial extent, Red River alluvial aquifer base contours and wells, isopach showing combined thickness of the Red River alluvial aquifer sand and gravel units, wells used to construct the isopach of the Red River alluvial aquifer, and well points that were used to construct 25-foot contours showing the altitude of the base of the Red River alluvial aquifer. Datasets are shown in figures of the larger body of work "Hydrogeologic framework of the Red River alluvial aquifer and Carrizo-Wilcox aquifer, in northwestern Louisiana" (Hays and others, 2021).
The groundwater-level change maps for the Sparta-Memphis aquifer are constructed as a point-to-point comparison between wells measured in both 2013 and 2015. Wells not measured in both 2013 and 2015 were not included in the change maps construction. The 2013-2015 change map contains 241 corresponding wells. Groundwater-level differences were calculated by subtracting 2013 groundwater-level measurements, in feet below land surface from the 2015 groundwater-level measurements, in feet below land surface.
