Krause Springs has been called the most beautiful swimming hole in Texas. Approximately 30 miles west of Austin. The property has 32 springs and a spring-fed, man-made pool and has been privately owned by the Krause family for over 50 years.
Okay so this isn't Katy, but it's not far -this is a great article on the water pools of Texas. The cool water of Barton Springs pool invites people of all ages to swim and relax in Austin’s summer sun. I love this place!
