What happened

The episode as NWS STO wrote it up.

A gate failure on Cresta Dam sent a surge of water (measured as 14.5 feet high at the nearest downstream gage) through the north fork of the Feather River. Several people trapped by the sudden surge had to be rescued by helicopter. The release contributed to a four inch rise in the level of Lake Oroville.
