There are many reservoirs in the Feather River basin.

Frenchman Lake is a 25 minute drive from my home. Snow is very deep(in the typical places) and the lake is full.
More pictures have been added.
It sounds like they may be holding back somewhat upstream to allow time to prepare for using the main spillway at Oroville again. I wonder if, when they open it up, they will open up also upstream so that inflows increase into the Oroville Reservoir...
