Edwards and Trinity Aquifers map. The Edwards Aquifer is one of the most prolific artesian aquifers in the world. [2] Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer's region.
Edwards Aquifer in Texas is important as a water supply aquifer and the source of major springs. This carbonate aquifer has historically been providing high quality water for nearly 2 million people, and even today, is completely full because of tremendous recharge from a number of area streams, rivers and lakes. The primary risk to this ...
The map layer was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series "Ground Water Atlas of the United States". The published maps contain base and cultural features not included in these data.

The area is well drained; rainwater flows into the Edwards Aquifer recharge zone at the south of the plateau to feed rivers to the south. Rainfall varies from 15 to 33 inches per year, typically, from northwest to southeast, and the area has a moderate temperature and a reasonably long growing season.
Barton Springs is the main discharge point for the Barton Springs segment of the Edwards Aquifer of Texas, a well known karst aquifer. Geologically, the aquifer is composed of limestone from the Cretaceous period, about 100 million years old. Fractures, fissures, conduits, and caves have developed in this limestone.
The Comal Springs are fed by the Edwards Aquifer, a large karst aquifer that runs through most of central Texas. The aquifer consists of porous, water-bearing limestone features which channel rainfall and surface runoff from the aquifer's recharge zone down to various discharge zones, including the springs.
