EAA Board Meeting in Hondo held on January 1, 2001

June 28, 2026, marks a major milestone for the Edwards Aquifer Authority (EAA): 30 years of managing, enhancing, and protecting one of Texas’ most vital natural resources.

Since officially beginning operations in June 1996, the EAA has worked to balance the needs of communities, ecosystems, agriculture, and industry while ensuring the long-term sustainability of the aquifer system. Today, the EAA manages the Edwards Aquifer for all of Uvalde, Medina, Bexar counties and portions of Atascosa, Caldwell, Comal, Guadalupe, and Hays counties, serving millions of Texans who rely on the Edwards Aquifer as a source of water.

Why we’re here

The Edwards Aquifer Authority was established following the passage of the Edwards Aquifer Authority Act by the Texas Legislature in 1993. This was created in response to growing concerns surrounding aquifer depletion, which affected spring flow and endangered species. The EAA began a new chapter in groundwater management when it officially launched in June of 1996.

30 Years of Progress

Over the years, the EAA has achieved significant milestones that continue to shape the future of water conservation in south central Texas. One of the EAA’s most impactful achievements has been the implementation of the Edwards Aquifer Habitat Conservation Plan (EAHCP). This helps protect habitat for endangered species and maintain healthy spring flows at the Comal and San Marcos springs, especially during a drought.

The EAA has also become a leader in aquifer research and monitoring by utilizing advanced technology to track aquifer levels, spring flows, and water quality in real time. Its scientific efforts help inform regional water management decisions and provide valuable data. The EAA also expanded its research capabilities through the development of the Field Research Park, a 150+ acre living laboratory located within the Edwards Aquifer Recharge Zone. The site supports studies on recharge processes, karst geology, native ecosystems, and aquifer sustainability.

Education has remained at the heart of the EAA’s mission. Since opening in 2022, the Education Outreach Center (EOC) has welcomed over twenty thousand visitors from across Texas and beyond through interactive exhibits, educational programming, and community events.

For 30 years, the EAA has also invested in people. From interns and student researchers to scientists, educators, and directors, the organization has provided opportunities for professional growth while creating a collaborative culture dedicated to protecting Texas water resources.

Looking Toward the Future

As the EAA celebrates its 30th anniversary, the organization continues to look ahead. Population growth, climate variability, and increasing water demands present challenges, but the EAA remains committed. The past 30 years have demonstrated the importance of science-driven conservation and strong public partnerships. Through the EAA, future generations will continue to benefit from the Edwards Aquifer for decades to come.
