On March 2, 2020 a talk was given to AGS titled: “Hydrogeology of Western Travis County.” The report is now available on the BSEACD’s website—click here. The Table of Contents of the atlas is shown below.

This study presents a compilation of existing and new hydrogeologic data intended to improve the collective understanding of groundwater resources in SWTC and beyond. We hope the results of this study will provide a baseline for future groundwater studies of the region and help inform strategies and policies to manage and protect the region’s groundwater resources.

Printed versions will come soon and we plan to have all the digital (GIS) data available in the near future.
