Replication Data for: Hydrogeologic Data along a Transect from Northern Hays County to Bell County, Central Texas

The dataset is a spreadsheet containing subsurface hydrogeologic data for wells in support of a study called: Hydrogeologic Investigations of the Trinity Aquifers along a Transect from Northern Hays County to Northern Bell County, Central Texas

A geologic cross section presented in the Atlas (Hunt et al., 2020) was extended north of the Colorado River into Bell County (Figure 1; C-C’-C”). The goal was to better characterize the hydrogeologic relationship between areas of drawdown observed within western Travis County and the significant drawdown experienced over the last 100 years in the northern Trinity Aquifer. Results indicate that more water-level data are needed in Williamson County, and in particular for the Lower Trinity; however, the drawdown observed in western Travis County appears to be consistent with regional drawdown throughout the northern Middle Trinity Aquifer.

This information has important implications for the conceptual model of the Trinity Aquifer and for long-term groundwater availability of the region and lays the foundation for future work in the region.
