The Edwards Aquifer is more than a water source — it’s a living story that connects our past, present and future. It’s the reason settlers came to this area, and it’s the lifeblood of our growth. Our aquifer is a resource we can study and learn from. It’s an incredible wonder, and it’s why we’re here.

🤔 True or False: The Edwards Aquifer is a giant underground lake.
❌ False! The Edwards Aquifer isn't a single underground lake but a network of conduits, caves, and porous Edwards limestone that stores and transports water. Rainfall replenishes it, supporting millions of ...South-Central Texans, iconic springs, and unique ecosystems.
💙 Understanding how it works is crucial for its protection.

🛟 What does “refugia” mean?
Derived from the Latin word refugium, it means shelter or refuge.
The Edwards Aquifer Refugia Program (EARP) maintains protected, off-site populations of covered species at the San Marcos Aquatic Resource Center (SMARC) in San Marcos, TX and the ...Uvalde National Fish Hatchery (UNFH) in Uvalde, TX. These backup populations help safeguard vulnerable species if a catastrophic event threatens their natural habitat in the Comal or San Marcos springs systems.
It’s one more way science and collaboration help protect the Edwards Aquifer ecosystem.

Improved Aquifer Conditions in Uvalde, TX Result in End of Critical Period Management for the Uvalde Pool
San Antonio, TX – The Edwards Aquifer Authority (EAA) has lifted all Critical Period Management (CPM) pumping curtailments for Edwards withdrawal permit holders in the Uvalde Pool ...of the EAA’s jurisdiction (Uvalde County) effective, Tuesday, August 11, 2026. The EAA declared the lifting of CPM based on improved aquifer conditions as the 10-day average at the J-27 index well measured 850 feet above mean sea level (ft. amsl), which is above the threshold for all stage restrictions within the Uvalde Pool. The Uvalde Pool has been under a stage of CPM reductions since June 2022 due to prolonged drought. However, significant rainfall across much of the region in July has caused the Uvalde Pool to trend upward over the past few weeks.
The EAA is a groundwater conservation district that manages, enhances, and protects the Edwards Aquifer, a major groundwater system serving approximately two-and-one-half million South Central Texans. The EAA jurisdiction spans across 8 counties including Uvalde, Medina, Bexar, and parts of Atascosa, Caldwell, Guadalupe, Comal and Hays counties.
