Director Precincts Redistricted
The new Director Precinct boundaries were finalized at the May 26, 2016 Board meeting after extensive research, public comment, and discussion. The precincts extend into the shared territory in Hays County and are meant to group communities of interests and their common sources of water supply. Very generally, there are two City of Austin urban […]
What Makes a Good Monitor Well?
Aquifer conditions are dynamic and therefore water levels can fluctuate because of drought, recharge, and pumping. Monitor wells help track these changes and inform policy to help protect water supplies and springflow for all users. After all, groundwater is a shared resource. We often get asked the question, what makes a good monitor well? In […]
Pleasant Valley Spring: A Newly Documented Karst Spring of the Texas Hill Country Trinity Aquifer
Texas Hill Country springs provide baseflow for rivers that recharge the downstream Edwards Aquifer. This study is an initial characterization of Pleasant Valley Spring (PVS) and recognition of its significance for the Hill Country, Middle Trinity Aquifer, and the Edwards Aquifer. PVS is a perennial, artesian, karst spring complex located in the bed of the […]
Influence of Faulting and Relay Ramp Structures on Groundwater Flow in the Karstic Edwards and Trinity Aquifers, Central Texas, USA
The Cretaceous-age Edwards and Middle Trinity Aquifers of central Texas are critical groundwater resources for human and ecological needs. These two major karst aquifers are stratigraphically stacked (Edwards over Trinity) and structurally juxtaposed (normal faulting) in the Balcones Fault Zone. Studies have long recognized the importance of faulting on the development of the karstic Edwards […]

Press Release: Hays County Trinity Aquifer Annexation Now Official
For Immediate Release: Saturday, June 20, 2015 For more information, contact: Robin Gary, Senior Public Information and Education Coordinator, (512) 282-8441 or rhgary@bseacd.org Hays County Trinity Aquifer Annexation Now Official Yesterday marked the effective date of HB3405, which brings the previously unregulated Trinity Aquifer portion of Hays County under management of a groundwater conservation district–the […]
Potentiometric Investigation of Two Large Springs Discharging From the Middle Trinity Aquifer, Western Hays County, Texas.
Pleasant Valley Spring (PVS) and Jacob’s Well Spring (JWS) are large karst springs providing perennial baseflow to the Blanco River and Cypress Creek, respectively, which eventually recharges the Edwards Aquifer. In order to better understand groundwater flow and sources of recharge to these springs (springsheds), we created a potentiometric map of the area surrounding the […]
Groundwater Flow as Evidenced from a Historic Petroleum Contamination Site, Barton Springs Segment of the Edwards Aquifer, Austin, Texas
Leaking petroleum storage tanks from gas stations are one of the most common sources of contamination of groundwater in the U.S. and Texas. In 1992 a 2,900 gallon gasoline and diesel release occurred at the Big Wheel Truck Stop located on the highly sensitive Edwards Aquifer in Austin, Texas. The fate and transport of the […]
Potentiometric Surface Investigation of the Middle Trinity Aquifer in Western Hays County, Texas
Pleasant Valley Spring (PVS) and Jacob’s Well Spring (JWS) are large karst springs providing perennial baseflow to the Blanco River and Cypress Creek, respectively, which eventually recharges the Edwards Aquifer. JWS flow has become intermittent in recent years due to drought and increased pumping driven by nearby population growth within the Cypress Creek watershed. In […]
Hydrologic Influences of the Blanco River on the Trinity and Edwards Aquifers, Central Texas, USA
The Blanco River of central Texas provides an important hydrologic link between surface and groundwater as it traverses two major karst aquifer systems—the Trinity and Edwards Aquifers. The Blanco River is characterized by alternating gaining and losing stretches due to the presence of springs that discharge water into the river and swallets that drain water […]
