Summary
A hydrogeologic framework was constructed for the Coastal Lowlands aquifer system in southwestern Louisiana. Data from previous hydrogeologic and geologic studies were synthesized and expanded using 2,242 geophysical logs to map four hydrogeologic units: the Chicot aquifer system, Evangeline aquifer, Jasper aquifer system, and Catahoula aquifer. Raster surfaces were created for the base and thickness of each unit to provide a generalized framework to support regional groundwater studies. A table of the well information and point data used to generate the raster surfaces is included in this data release.

The U.S. Geological Survey (USGS), in cooperation with the Louisiana Department of Transportation and Development, has mapped the structure of four hydrogeologic units in southwestern Louisiana: the Chicot aquifer system, Evangeline aquifer, Jasper aquifer system, and the Catahoula aquifer. These data are intended to support investigations of groundwater resources at a regional scale, such as studies of groundwater availability, flow, and quality.
