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.

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.
Alaska holds the all-time U.S. record. The mercury plummeted to 80 degrees below zero on Jan. 23, 1971, in Prospect Creek, north of Fairbanks.
Location of the San Marcos Springs. The San Marcos Springs is an area of artesian outflow from the Edwards Aquifer along the Balcones Escarpment. More than 200 springs flow from three large fissures and other smaller openings in the rock. The springs provide most of the water for the San Marcos River, which flows southward from the springs ...
