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.

EAA Lifts Stage 4 and Returns to Stage 3 Permit Reductions for the San Antonio Pool
San Antonio, TX – The Edwards Aquifer Authority (EAA) has declared the lifting of Stage 4 and a return to 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 Sunday, April 26, 2026. Yesterday, the ten-day average at Comal Springs was 100 cubic feet per second (cfs), and the ten-day average at the J-17 index well is 632.7 feet above mean sea level (ft. amsl), which are each above the Stage 4 threshold for the EAA Critical Period Management Plan (CPM). The San Antonio Pool had been in Stage 4 since August 12, 2025.
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.
Tune in to Texas Public Radio's "The Source" to hear from host David Martin Davies as he chats with EAA General Manager, Roland Ruiz, and Steve Cargil, Edwards Aquifer Authority Board Member, Uvalde farmer, and owner of Cargil Produce as they discuss how the recent rains may have ...elevated aquifer levels but managing through drought is still top of mind.
This interview will be recorded live today, Monday, April 27, 2026, at 12:00 p.m.

Because of the ongoing drought water levels in the Edwards Aquifer have been dipping to some of the lowest in history. Yet development growth...

Thank you, Bill Taylor from KENS 5 & Kens5.com, for this week’s weather update! 🌧️ We’ve been seeing some much-needed rain lately, with portions even reaching the contributing zone of the Edwards Aquifer system.
While every drop counts, it’s important to remember that ...we’re still in extreme drought conditions. Let’s continue doing our part by staying mindful of water conservation every day. 💧🌎
Earth Day is a reminder that some of our most important natural resources aren’t always visible... but they are essential to everything we do. 🌎💧
The Edwards Aquifer is one of the most vital water sources in South-Central Texas, supporting communities, agriculture, industry, and ...unique ecosystems found nowhere else in the world. Protecting it requires thoughtful management, ongoing research, and a shared commitment to conservation.
At the Edwards Aquifer Authority, that responsibility drives everything we do, from monitoring aquifer levels and ensuring sustainable use to preserving the delicate balance of the aquifer system.
This Earth Day, we encourage everyone to take a moment to consider the role water plays in your daily life, and how small actions can help protect this critical resource for generations to come.

ICYM: Last Tuesday 4/14/26, Paul Bertetti, EAA Senior Director, Aquifer Science Research & Modeling, delivered our latest aquifer conditions report detailing the state of the Edwards Aquifer. ➡️This report is before this recent rainfall, but puts things into perspective. We are in about a 2... year rainfall deficit, so the recent rainfall is much needed but we still have a ways to go.
Stay safe out there everyone!
