Lake level projections
LCRA projections show levels in Lake Travis and Lake Buchanan will slowly fall as temperatures rise and water use increases in the next few months. In April, rainfall totals over the Highland Lakes watershed in the Hill Country were 1 to 2 inches below normal, and little water flowed into the lakes.
At 9,417 acre-feet, inflows into the lakes in April were about 9 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, agriculture and the environment in the lower Colorado River basin.
