Georeferenced Maps of the Thickness of the Sparta Aquifer in MS, AR, and LA, 1961 to 1996

Metadata Updated: October 29, 2023

The Sparta aquifer is a primary source of groundwater in north-central Louisiana. In 2015, more than 60 million gallons per day were withdrawn from the Sparta aquifer, of which over 90 percent was used for public supply and industrial purposes (Collier, 2018).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.
