models have increased precipitation amounts both upstream and downstream of travis with a tropical system moisture starting Tuesday into weds
they may have to close some gates on travis ..the lake is at 703.65 now and slowly falling...I think the lake will still be about 701.25 the the rain starts Tuesday afternoon and Buchanan 1018.35 or so
in the past 12 hours Buchanan has fallen .22 feet, Travis .34 feet
LCRA:
Mansfield Dam / Lake Travis
Lake Travis reached a peak level of 704.39 on Saturday, October 20. Based on current conditions, LCRA now projects that Lake Travis will slowly fall in a range of 704 to 702 feet above mean sea level today and Monday. Those projections could change if additional rain falls in the lower Colorado River basin.
There are currently four floodgates open at Mansfield Dam, which forms Lake Travis. LCRA is making controlled releases from the flood pool of Lake Travis to manage river levels downstream of Mansfield Dam. Weather forecasts call for additional rain over the next several days, which could cause a significant increase in storm runoff, which may result in the need to open or close floodgates in the coming days.
Additional rainfall could cause LCRA to need to open up to four additional floodgates at Mansfield Dam to move floodwaters downstream. If that happens, we will alert the public and local officials immediately. Anyone downstream of Mansfield Dam should remain prepared for the potential that additional floodgates may be needed. Please check this page frequently for updates.
Buchanan Dam / Lake Buchanan
One floodgate is open at Buchanan Dam. Flood releases from Lake Buchanan have been reduced as inflows to Lake Buchanan have declined. Based on current conditions, LCRA projects that floodgate operations at Buchanan Dam will continue today and tomorrow, Oct. 21 and 22, to gradually lower Lake Buchanan to near 1,018 feet msl. Forecasts for Lake Buchanan and gate operations at Buchanan Dam may change with additional rainfall.
new NAM model is very concerning dumps 2-3 inches in the basin and 3-5 just downstream with a faster arrival time too
its the first of the models in this evening
so we will have to wait a few hours for the others
