Data Compilation and Database Structure for the Geodatabase Accompanying the Hydrogeologic Atlas of Southwest Travis 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 southwestern Travis County (SWTC). 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), which […]
Evaluating the Potential Groundwater Availability within a Lower Trinity Aquifer Well Field, Balcones Fault Zone, Hays County, Central Texas
Groundwater availability from the Edwards and Middle Trinity Aquifers in the study area is generally limited, however, the Lower Trinity Aquifer within the study area is untested because of the aquifer depths, assumed low yields, and poor water quality. This study provides an initial assessment of groundwater availability in a Lower Trinity well field based […]

Springshed Delineation in a Karst Aquifer in Hays County, Central Texas
Hays County is experiencing some of the highest growth rates in the country, and groundwater is the primary option for water in the county. One spring in the study area, Jacob’s Well, experiences periodic cessation of flow due to a combination of drought and pumping from nearby water-supply wells. Jacob’s Well is important for ecological […]
Geochemical Evaluation of Hydrogeologic Interaction Between the Edwards and Trinity Aquifers Based on Multiport Well Assessment in Central Texas
The Edwards and Trinity Aquifers are major aquifers of Central Texas that provide water supply for over two million people and contain springs that are hydrologically and ecologically important to the region. The Edwards Aquifer overlies the Trinity Aquifer but is geologically juxtaposed along the Balcones Fault Zone. Thus, understanding the hydrologic connection is necessary […]
Summary of Groundwater Tracing in the Barton Springs Edwards Aquifer from 1996 to 2017
The Barton Springs segment of the Edwards Aquifer is an important resource for the region and understanding how the aquifer functions is critical to the conservation and preservation of the resource. Groundwater tracing is an important tool used to characterize the recharge areas, flow paths, groundwater velocities, dispersion, and fate of water in karst aquifers. […]
Blanco River Aquifer Assessment Tool A Tool to Assess How the Blanco River Interacts With Its Aquifers: Creating the Conceptual Model
The Blanco River watershed spans five counties through the Texas Hill Country and supplies water to some of the fastest growing population centers in Texas, if not the country (Figure ES – 1). Over this reach, the Blanco River is both fed by and feeds the Trinity and Edwards aquifers, blurring the line between groundwater […]
Evaluation for the Development of a Jacob’s Well Groundwater Management Zone in Hays County, Texas
Jacob’s Well is a karst spring originating from the Lower Cretaceous, Middle Trinity Aquifer and is located in the Cypress Creek watershed near Wimberley, Texas. The Middle Trinity Aquifer is the primary groundwater resource for water supply in the region. Jacob’s Well flow responds to climatic variations of both short- and long-term cycles. Groundwater pumping […]
March 2018 Potentiometric Map of the Middle Trinity Aquifer, Central Texas
The Middle Trinity Aquifer is the primary groundwater resource for the central and western portions of Hays County. Groundwater levels and potentiometric surface maps provide critical information about the hydrologic relationships of recharge, discharge, and storage within an aquifer, and the direction of groundwater flow. This report provides a potentiometric map of the Middle Trinity […]
Regional Geologic Geodatabase Project, Central Texas
Geologic data are used by hydrogeologists to develop a better understanding of aquifers. Geophysical logs, driller’s and cuttings logs, and outcrops provide valuable information about aquifer characteristics and can be used in combination with other geologic data to characterize groundwater resources. The purpose of this project was to build a geodatabase of geologic control points […]
