I suspect we will find out it’s currently going over the emergency spillway still slow. Looks like it’s doing a pretty good job of removing the overburden from the bedrock.
The water levels have, surprise, messed up their water release plans. They’ve slowed the main spillway and had to shutdown an auxiliary generator that took another 12000 CFS because the concrete broken out of the spillway is backing water up.
Good news its becoming sunny. For three days. Then the longer range forecast says basically 6 straight days of rain in Oroville and up land from the lake.
