Hamilton Pool Management Zone (HPMZ)
In August 2023, the Board of Directors of the Southwestern Travis County Groundwater Conservation District (District) approved the creation of the Hamilton Pool Management Zone (HPMZ) in southwestern Travis County. This designated area is home to a unique system of aquifers and springs, and the District may consider adopting tailored groundwater management rules and strategies to better protect these sensitive resources.

The District convened a stakeholder group to develop recommendations for potential new rules and management strategies specific to the HPMZ. This collaborative process culminated in a final report prepared and presented by facilitator Christy Muse, which documented the group’s work and proposed strategies.
The District Board formally accepted the final stakeholder report on August 14, 2024, and held workshops on October 30, 2024, and January 30, 2025, to review the recommendations and consider next steps. In addition to exploring potential rule amendments to enhance aquifer and spring protections, the Board echoed the HPMZ stakeholders’ emphasis on the critical role of public outreach and education in advancing the District’s mission.
What is the source of water to Hamilton Pool?
Geologist Brian Hunt explains the Middle Trinity Aquifer system and the springs that feed Hamilton Pool in Central Texas. These spring systems are why Hamilton Pool has stayed filled—even during dry periods. But that flow isn’t guaranteed. Learn how geology, water, and conservation efforts are working together to protect this iconic Central Texas landmark.
