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.
Dive into deeper discovery through education.
There’s so much to explore at the EAA Education Outreach Center. We’ve got a hub of interactive exhibits and hands-on activities designed to inspire a deeper connection to the water that sustains our region.

EAA Declares a Decrease to Stage 3 Permit Reductions for the San Antonio Pool
San Antonio, TX – The Edwards Aquifer Authority (EAA) has declared Stage 3 Critical Period Management for Edwards groundwater permit holders in the San Antonio Pool of the EAA’s jurisdiction (Medina, Bexar, ...and parts of Atascosa, Caldwell, Guadalupe, Comal, and Hays counties) based on improved aquifer conditions effective Monday June 9, 2025. Yesterday, the ten-day average at the J-17 index well is 633.2 feet above mean sea level (ft. amsl), which is within the Stage 3 threshold for the EAA Critical Period Management Plan (CPM). Additionally, the ten-day average at Comal Springs was 101 cubic feet per second (cfs), which is within the Stage 3 threshold as well.
As shown below, CPM Stage 3 for the San Antonio Pool reduces the annual authorized withdrawal amounts available to affected Edwards groundwater permit holders by 35 percent of their withdrawal amounts based on the number of days CPM is in effect for the indicated stage reduction. These reductions apply to all Edwards Aquifer groundwater permit holders authorized to pump more than three acre-feet annually. This includes industrial and agricultural users, as well as water utilities authorized to pump water from the Edwards Aquifer for delivery to their respective customers. All affected permit holders must also report their pumping totals to the EAA on a monthly basis.
Residents and businesses within those counties who receive their water from a public water system should follow their respective water providers’ directives regarding water use practices. It should be noted that the EAA does not enforce lawn watering activities or other general water limitations beyond the curtailment of withdrawals from the Edwards Aquifer. Any enforcement of such activities or limitations is enforced by a municipality. The EAA does not regulate the general public but instead regulates Edwards well owners with withdrawal permits authorizing their right to pump from the aquifer.
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.
