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.

Veterans, thank you for your service! 🇺🇸
In honor and observance of all who have served, our office is closed tomorrow, November 11, 2025.
🌎💧 Ever wondered what it really takes to protect the incredible aquifer we have beneath our feet?
Logan Schmidt, Principal Geoscientist of Aquifer Science Research, shares how different technology helps to measure the water cycle and how water interacts with the ecosystem in the ...recharge zone. Watch the full video and learn more on our YouTube channel, featuring Logan and other EAA scientists discussing their efforts to safeguard the aquifer through technology, dedicated stewardship, and science. 🌿🔬💙

Tomorrow is national STEM/STEAM Day, and we are proud to offer FREE STEAM field trip experiences at our Education Outreach Center to inspire young minds to one day be a part of the Science, Technology, Engineering, Art, and Math (STEAM) fields!
The future of STEAM depends on the students ...of today, so be sure to add the EAA Education Outreach Center to your list of places to visit this season or next! Book your FREE visit here: https://www.eaaeoc.org/
💧Conservation is key! Water resources are not infinite here in Texas, and the quantity and quality of groundwater within the aquifer depends on preservation and conservation for it to remain plentiful for generations to come. 🌎💙
Our EAA team is constantly researching and ...protecting this vital groundwater source to keep it sustainable for the future. You can help by saving water at home, choose eco-friendly habits, and plant Texas native plants which can survive in our climate with less water. 🌿✨
Together, we can protect the Edwards Aquifer, one drop at a time.💧

💧 Aquifacts with Brent: Did you know the Edwards Aquifer provides water to more than 2.5 million people across Texas? It’s also the lifeline for endangered species like Texas wild rice and the Fountain darter, both of which depend the Comal and San Marcos Springs which emanate from the ...aquifer. 🌿🐟
Every fact reminds us why protecting this incredible groundwater resource matters, for people, wildlife, and generations to come.

We wish you weir here…🎵💧
Last November, our aquifer science team began observing the effects of land management techniques on runoff within two small watersheds at the EAA Field Research Park (FRP), in a study known as Project Weir.
➡️ What are weirs? They are physical ...structures resembling small dams with a notch that can control water flow within a drainage or stream channel and are used to accurately measure streamflow.
In hydrology, a weir capitalizes on this principle by channeling water through a basic shape (a rectangle or V-shaped notch) of known dimensions, making flow calculations simple and accurate.
➡️ EAA Project Weir Research
EAA scientists aim to observe potential changes in runoff dynamics before and after applying nature-based solutions like brush and rock berms within the sub-watersheds. Furthermore, pressure sensors within the weir structures are used to track and monitor flow after rain events.
Data for Project Weir will continue to be collected across multiple seasons and meteorological conditions. After sufficient storm data has been accumulated, researchers will assess the land management practices that were installed and monitor for any changes in runoff.
This project and others like it, allows the EAA to better understand recharge mechanisms in karst aquifers and assess the potential benefits of land management for recharge enhancement.💧
