For the first time since 2007, the Lower Colorado River Authority opened the floodgate at Mansfield Dam Monday morning.
LCRA said in a release that more than 90,000 acre-feet of water is expected to flow into Lake Buchanan in the next 3-4 days. Buchanan, Wirtz and Starcke Dams will continue hydroelectric generation and floodgate operations, LCRA said.
Hydroelectric generation will continue at Mansfield Dam, LCRA said. Around 8 a.m. April 25, the LCRA will open a floodgate and it is expected to remain open for “at least 48 hours.”
LCRA partially closed the floodgate at Buchanan Dam around 12 p.m. Sunday. As of 7 p.m. Sunday, no floodgates are open on Wirtz or Starcke Dams and “Inks Lake is less than two feet (sic) over the spillway of Inks Dam and falling slowly.”
Floodgate operations at Tom Miller Dam, which creates Lake Ausitn, are expected to continue during the week. LCRA said it will increase floodgate flow Monday “to accommodate the increased flow entering Lake Austin upstream from Mansfield Dam.”
