You can pull up a data set showing Alamo lake level, acre/feet, average inflow (cfs), and instantaneous outflow (cfs).

With this data plus knowing that the targeted lake level elevation is 1,125', you can start to gauge how long they will be letting water out. Furthermore, using the Water Control Plan at https://www.spl.usace.army.mil/Media/Fact-Sheets/Article/1511614/alamo-dam-water-control-plan/ you can even figure out a sort of release schedule.

Definitely get in touch with the UACE Los Angeles division and ask them what they are planning. Even the Alamo SP staff can help. Wouldn't wanna be out there and have the water shut off or turn up to 7k cfs!
