Structure maps of the Carrizo-Wilcox aquifer in northwestern Louisiana

Science Center Objects

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation with the Louisiana Dept. of Ttransportation and Development, is creating structure maps and hydrogeologic cross-sections to describe the fresh groundwater resources throughout the area. The period of the study is two years.
