Some reports I heard today said Lake Travis, just west of Austin, would reach full capacity as a result of the upstream flooding. From the chart, it looks like the water level has exceeded the full pool level.
I drove by Mansfield Dam (the dam that forms Lake Travis) about noon today and saw a lot of cars parked on the loop road that goes under RM 620. Apparently folks were watching a high water release from Mansfield Dam. The river was much higher than normal downstream of the dam flowing on into Lake Austin but did not appear at flood levels downstream then.
Last I heard the Mansfield Dam had 4 floodgates open. They haven’t opened any floodgates on the Buchanan Dam yet, but it’s 95% full up.
EVERY gate on that dam is open.
