Our Purpose Runs Deep

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.

The Edwards Aquifer Authority’s Environmental Data Portal is your gateway to today’s research, insights, and discoveries driving sustainability and innovation for the region.

Did you know there’s a massive cistern hiding in plain sight at the Edwards Aquifer Authority HQ? Since 2012, this tank has quietly collected hundreds of thousands of gallons of water over the years straight from roof rainfall runoff and the HVAC condensate!💧

That reclaimed water is ...then used to irrigate the EAA grounds, which are filled with beautiful, drought-tolerant and Texas native plants.🌿🌞

Remember, water conservation doesn’t always require big systems - sometimes, it starts with the small stuff:
🪥 Turn off the faucet while brushing your teeth
🚿 Take shorter showers
🌼 Plant native species in your yard

Every drop matters and big or small, conservation takes us all.💙

"So our farm is family. I tell people the three F’s - Faith, Family, and Farm. Those are the three things I feel strongly about."💙

At McFadin Farms in Uvalde, TX, farming isn’t just about crops - it’s about legacy. On this Father’s Day, we’re honoring the generations... of dads, like Nathan and Archie, who remind us that it’s not just about what you grow, but who you grow with. 🌾

With center pivot irrigation, McFadin Farms is cultivating corn, cotton, cabbage, cucumbers, wheat, and sunflowers more efficiently - protecting water, soil, and the future for the next generation.

Big thanks to PepsiCo U.S. Beverages and U.S. Foods for supporting the Edwards Aquifer Authority’s Groundwater Conservation Program and helping families like this thrive.

Capturing the impact of this morning's rains, along with Ann-Margaret Gonzalez of the EAA, and videographer extraordinaire Taylor James Johnson. We'll have some neat stuff to share with you, straight from the Field Research Park, shortly!

Again, we direct your attention to the always valuable www.TexMesonet.org, operated by our friends at the Texas Water Development Board. You can check rain gauges across the area to determine where and how much rain has fallen -- in the last hour, up to the last seventy-two hours. You'll see... the impact of last night's rain on some parts of our region -- especially in Medina, Bexar, and Comal Counties. Let's keep our fingers crossed for more rains across the entire 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.
