Swimming in Barton Springs Pool
Barton Springs Pool is located in Zilker Metropolitan Park, the crown jewel of Austin parks. Barton Springs is the 4th largest natural springs in the state of Texas. The pool covers 3-acres and is fed from under ground springs that maintain the pool’s average temperature at 68 F degrees year-round. The main spring pumps an average of 27 million gallons of water a day.

Native Americans called these the Sacred Springs and came here to heal their wounds. The springs passed through many American hands, including those of William “Uncle Billy” Barton and Colonel A.J. Zilker. Barton Springs Pool had been a popular swimming hole for decades when it became part of Zilker in 1917. In 1929 the irregular-shaped pool was enlarged to 1,000 feet long.

The only known surface habitats of the Barton Springs Salamander are located in Barton Springs Pool, Eliza Springs, Old Mill Springs and Upper Barton Springs. The City of Austin and the U.S. Fish and Wildlife Service are working to support operation of the pool while protecting this endangered species.
