The Colorado River is an important part of the past, present and future of Texas. Perhaps most importantly, 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.
Why are the lakes important?

Where does rain have to fall to flow into the region’s water supply reservoirs?
The Highland Lakes capture water during rainy times so we have reliable water supplies during drier times. In 2018, inflows, or the amount of water flowing into the lakes, were extremely low through the summer, and historically high toward the end of the year.
