The Sparta aquifer is a primary source of groundwater in north-central Louisiana with more than 60 million gallons of water per day being withdrawn in 2015, and public supply and Industry account for over 90 percent of the water-use demand from the Sparta aquifer (Collier, 2018). Concentrated withdrawals from the Sparta aquifer have caused regional water-level declines within the Sparta aquifer (McGee and Brantly, 2015). Widespread concern about the potential effects of declining water levels has brought forth many questions regarding the sustainability of the aquifer as well as continued saltwater intrusion. In cooperation with the Louisiana Department of Transportation and Development, the U.S. Geological Survey...

The most widely used aquifer for industry and public supply in the Mississippi embayment in Arkansas, Louisiana, Mississippi, and Tennessee is the Sparta-Memphis aquifer. Decades of pumping from the Sparta-Memphis aquifer have affected ground-water levels throughout the Mississippi embayment. Regional assessments of water-level data from the aquifer are important to document regional water-level conditions and to develop a broad view of the effects of ground-water development and management on the sustainability and availability of the region's water supply. This information is useful to identify areas of water-level declines, identify cumulative areal declines that may cross State boundaries, evaluate the effectiveness...

A digital dataset of analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment in Missouri, Kentucky, Arkansas, Tennessee, Louisiana, and Mississippi was developed from J.E. Reed's "Analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment" (1972). The plate was georeferenced to North American Datum 1983 and projected to USA Contiguous Albers Equal Conic (U.S. Geological Survey version) projection (standard parallels 29.5 and 45.5 degrees, central meridian -96 degrees, and latitude of origin 23 degrees). Once georeferenced (using ArcMap v 10.4.1), individual potentiometric contours were digitized manually. Figures included in the digital dataset are figures 2...
