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.

1 acre-foot of water is about the same height as Wemby going in for a slam dunk?!
Here's the play by play of that math:
🏀 an NBA court is 4,700 square feet
💧 1 acre-foot of water is 325,851 gallons of water
➡️ Therefore, if the court transformed into a ...pool, the water would reach to about the height of Wemby holding a basketball above his head going in for a slam dunk. Which is about 43,560 cubic feet of water at 9.26 feet in depth!

Happy National Caves and Karst Day!
Did you know caves play an important role in the Edwards Aquifer system? These underground spaces help move and store water, provide a habitat for unique species, and offer a window into the geology beneath our feet.
The U.S. has four of the ...world’s ten longest caverns and gets about 40% of its drinking water from karst aquifers, making National Caves and Karst Day a national treasure.
Protecting caves and karst landscapes, helps protect groundwater resources, like the Edwards Aquifer, which sustain our communities and ecosystems.
