Lake level projections
LCRA projections show levels in Lake Travis and Lake Buchanan will slowly fall as temperatures rise and water use increases during spring and summer unless weather conditions are wetter than normal. In late March, spring storms brought heavy rain to some parts of the lower Colorado River basin, but lake levels stayed relatively steady as the rain amounts over the Highland Lakes watershed were light.
At 16,445 acre-feet, inflows into the lakes in March were about 19 percent of the historic monthly average. Inflows are the amount of water flowing into the lakes estimated from measurements at four gauges upstream. (An acre-foot is 325,851 gallons.)
The Highland Lakes were created to manage floods and capture water when it rains to ensure the region has a reliable water supply during dry times. Lakes Travis and Buchanan provide water for more than a million people and to industries, businesses, the environment and agriculture in the lower Colorado River basin.
