I wonder if those lakes use more water for consumption than we do..and also have had less run off rain.
Buchanan and Travis are strictly for flood control. I’ve read that Buchanan dam could break and Lake Travis could hold most of the water before going over the top of Mansfield dam. That is if Travis is at 650’ MSL.
The LCRA was letting water out of Travis last month to get fresh water to the oyster beds. Now all the rain water from the recent rains will end up in the gulf too. All the major runoff was below Mansfield dam.
