Quite a little canyon being eroded out there, how long has this been going on? Last I saw was yesterday morning, but it’s hard to tell what’s current and what isn’t. They’re going to have another issue and a big one with blockage due to that erosion diverting flow of the river itself soon. That will lead to flooding in Oroville, no matter what else happens up above.
I think it might of happened this morning. Someone posted a little video of it on youtube that was taken in the afternoon. That gif is of that video.
