Update: The Lower Colorado River Authority issued information around 7 a.m. Saturday stating the open floodgate at Tom Miller Dam has been closed for now, but levels in the Colorado River and tributaries downstream of Mansfield Dam are elevated due to runoff from heavy rains Friday and early Saturday. LCRA officials expect to partially reopen a floodgate at Tom Miller Dam after downstream flood conditions improve and releases through hydroelectric generation at Mansfield Dam are increased over the next day or two. LCRA information also states Lake Travis is expected to rise to between 683 and 685 feet above mean seal level by Sunday, and releases through Mansfield Dam have been stopped and will resume when conditions improve along the Colorado River downstream of the dam. Original story: The Lower Colorado River Authority is urging caution Friday evening as strong thunderstorms move along the Colorado River watershed. A statement issued by the LCRA states floodgate operations are underway at Tom Miller Dam in Austin in response to heavy rainfall and rising water levels in Lake Austin. One floodgate has been partially opened with more action possible depending on coming rainfall. The statement encourages anyone living near the Highland lakes to be cautious and take action to protect people and property. "Conditions are changing rapidly with additional rainfall and increasing inflows," the LCRA warning states. "LCRA is closely monitoring conditions and encourages the public to remain alert to local conditions and be prepared to take protective actions." The storms, which are producing moderate to heavy rain, have forced the LCRA to release runoff through hydroelectric generation at the Highland Lakes.
