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 creek begins in northern Hays County and flows 40 miles (64 km) east through Austin, draining into the Edwards Aquifer recharge zone in southwest Austin. [2] The stream then reemerges at Barton Springs and proceeds toward Lady Bird Lake (formerly Town Lake), where it joins with the Colorado River.
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 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.
Shoal Creek is the largest of Austin’s north urban watersheds, encompassing approximately 8,000 acres (12.9 square miles). About 27% of the watershed is over the Edwards Aquifer Recharge Zone. [1] Its length is approximately 11 miles. It runs parallel to and between Waller Creek to its east and Johnson Creek to its west.
This year, the system has seen an 850,000-acre-foot increase in water flowing into the river from the aquifer, 300,000+ acre-feet in aquifer recharge, a 400-500 cubic-feet-per-second increase in ...
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
