Hydrogeologic Investigations of the Trinity Aquifers in Western Travis County along a Portion of Lake Travis and a Transect from Northern Hays County to Bell County, Central Texas

The Barton Springs/Edwards Aquifer Conservation District (BSEACD), in cooperation with Travis County, compiled existing and new hydrogeologic data to evaluate groundwater resources in central Texas. Analysis and interpretation of these data provide the foundation for hydrogeologic evaluations presented in the Hydrogeologic Atlas of Southwest Travis County, Central Texas (Hunt et al., 2020). The Atlas describes the hydrogeologic framework, aquifer conditions, and conceptual model of the Middle and Lower Trinity Aquifers in Hays and southwestern Travis County (SWTC). This report presents the continuation of the hydrogeologic studies in cooperation with Travis County. The studies described in this report help characterize two important hydrogeologic aspects identified in the Atlas of Hunt et al. (2020) that warranted additional investigation. This was accomplished through two focused studies: Study 1: Hydrogeologic Investigations of the Trinity Aquifers in Western Travis County Along a Portion of Lake Travis; Study 2: Hydrogeologic Investigations of the Trinity Aquifers along a Transect from Northern Hays County to Northern Bell County, Central Texas
