FLOOD WARNINGS_1557349758370.png.jpg

Strong storms moved through the Hill Country earlier today, and more rain is in the forecast through the weekend.

  • The only floodgate operation underway now is a partial floodgate opening at Tom Miller Dam. However, this could change as we get more rainfall. LCRA is monitoring rainfall and inflows and is ready to open additional floodgates along the system of dams on the Highland Lakes, if necessary.
  • LCRA projects that over the next two or three days, Lake Buchanan will rise to between 1018 to 1020 feet above mean sea level. LCRA projects that over the next one to two days, Lake Travis will rise to between 684 and 685 feet msl, three to four feet into the lake’s flood pool.
  • The National Weather Service has issued flood warnings for the San Saba River at San Saba, which flows into the Colorado River upstream of Lake Buchanan, and the Pedernales River at Johnson City, which flows into the Colorado River at Lake Travis. (NWS forecasts are available on the bottom of the Flood Operations Report.)
  • Flows in the Colorado River below Lake Travis continue to be high, with most locations at or above bank full. LCRA will continue to hold floodwaters in the flood pool of Lake Travis until downstream conditions lessen so as not to exacerbate flood conditions.
  • LCRA also is continuing to pass storm runoff downstream through hydroelectric generation at Buchanan, Inks, Starcke, Wirtz, Mansfield and Tom Miller dams.
  • The potential for flash flooding continues to be high, and we encourage everyone to remain alert to local conditions and to be ready to take action to stay safe.
