The Colorado River is an important part of the past, present and future of Texas. The Highland Lakes on the river northwest of Austin provide water for more than 1.4 million users, including communities, businesses, industries, agriculture and the environment.
The lakes are vital to maintaining a reliable water supply, providing flood management in the middle of Flash Flood Alley, creating hydroelectric power for the Texas power grid and much more. Information on this page explores the variety of ways LCRA manages the lakes and lower Colorado River for the benefit of the entire river basin.
