The Edwards Aquifer Authority (EAA) is a regional water management agency that oversees the use of the Edwards Aquifer, a vital water resource. Established in 1993, the EAA was created as a political subdivision of the state to safeguard and preserve the aquifer. By implementing a capped permitting system, the EAA ensures sustainable water withdrawals while protecting endangered species in the aquifer-fed Comal and San Marcos springs.

Covering over 8,000 square miles across eight counties, the EAA regulates the Balcones Fault Zone Edwards Aquifer, which supplies water to more than 2. 5 million people. The EAA collaborates with other groundwater districts and stakeholder groups to maintain integrity, transparency, and respect for this precious resource.

The EAA offers various services and programs to support its mission, including groundwater permit management, drought management, habitat conservation planning, educational outreach initiatives, and scientific research on aquifer protection. With a commitment to accountability and environmental stewardship, the EAA plays a crucial role in ensuring the sustainability of the Edwards Aquifer for present and future generations
