Education and Awareness on Ground Water

We never know the worth of water till the well is dry
— Thomas Fuller


What is an aquifer? Groundwater from aquifers sustains life of every kind in Texas. It is a key resource to every industry in Texas.
An aquifer is best defined as a layer of saturated rock and the water in its pores. Aquifers were formed very slowly over vast periods of time. Water in aquifers comes originally from the surface of the Earth.

The Edwards Aquifer consists of three different zones (drainage, recharge, and artesian) covering the South Central Texas landscape.

National Geographic presents this short film showcase. Learn how groundwater was introduced back into this Hill Country restoration project by working with Mother Nature instead of against her. 

#DoYouKnowH2O? The San Marcos Springs ecosystem has some of the most environmental stability and flow reliability of any spring system in the Southwestern United States, attributing to water temperatures remaining at a nearly constant, year-round 70°F!

Take a journey through the unusual world that exists beneath a streambed. Called the hyporheic zone, this world of microscopic flora and fauna is vital to the health of rivers around the world. Find out why, and see the slime on streambed pebbles come to life! Meet for the first time the colorful and unknown world of the Hyporheic Zone and why it is important.

The purpose of the TWDB’s water-level program is to gain representative information about static water levels in aquifers (water levels unaffected by recent or nearby pumping) throughout the state in order to support water planning from the local to a more regional perspective
