Lake level projections
LCRA projections show levels in Lake Travis and Lake Buchanan will continue to slowly fall as temperatures remain hot and water use increases over the next few months. In May, parts of the Highland Lakes watershed in the Hill Country received above-average amounts of rain early in the month, but rainfall totals in most areas were 1 to 2 inches below normal.
At 22,149 acre-feet, inflows into the lakes in May were about 11 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. Lakes Travis and Buchanan were designed to fluctuate and are not constant-level lakes.
