The Oroville Dam is the highest in the nation.
Thanks for the new scanner link.
I urge anyone with loved ones in flooding areas to monitor local scanners and on-the-ground citizen feeds.
MSM reports via the DWR aren’t telling the whole story, IMHO. Evacuation plans are insufficient. Have your own evac plan in place, and a plan B.

I’d like to see some video of the action or inaction at the bottom of the spillway where they are trying to (I think) dredge out the river back towards the dam in preparation of running the generating units. I think they can pass about 17,000 GPM through the 3 units. There were also some bypass valves of some sort that I read about earlier, but those may have been damaged a few years ago and might not be available.
Dredging out that back channel towards the power plant and firing up those generating units will take more than a couple days.
WAY more.
That stinks - sooner = better, of course. But they have a ton of debris down there, I’m sure. I mean, it washed out an enormous amount of earth and loose rock.
Just getting in - catching up. SeanD was just on periscope, missed a lot but he’s evacuating, said something is going on with main spillway??
current water level at Oroville dam 854.23 feet as of 3:00 pm this afternoon. Capacity 900 feet. If I understood correctly when I read a few days ago, the main spillway can drain about one inch of waterfall every 24 hrs. According to Maggie’s chart upthread, 4-5 inches will put water over the top of the auxiliary spillway.
Grass Valley south of Oroville is on track for 7.5 to 10 inches starting Sunday night. To the north rainfall estimated around 4 inches.
At 100k CFS, it can lower the level much faster than that... the question is how high they want to bring the rate with the damage that has already occurred... IIRC, I think the main spillway (I damaged) was rated for 150k... they ran it at 100k for much of the last week to drop it 45ft while inflow was still ~30k CFS most of the week. Don’t think the water will top the espillway again, but there are lots of other concerns as well.

Driving through a flooded I-5 near Williams from trucker’s point of view
Feb 18, 2017
Trucker Joshua Willis kept plowing through the floodwater across Interstate 5 near Williams in this video.

Re 1450 - Love that view. Always happy to see electrical equipment. That’s my thing.

Looks like they’re down to 55,000 the last 4 hours. A little lower than expected. Maybe they want to be able to see what’s down at the bottom of spillway.
I thought Gene Hackman was in the Poseidon Adventure...
OK,
what do you think about the status of an electrical generator
that has been underwater for over a week, now.
(not to mention all of the control panels, etc...)
Has the generator (actually, there’s 3 of them) actually been under water for over a week? I had not heard that. Is there a link?
If it was, then it’s essentially toast. Might as well salvage it for the copper.
Links in this thread that I have read
said “the hydro plant is flooded”.
Maybe I am reading too much into that?
I think that it is not flooded, but there is that possibility. I’ve tweeted the CA-DWR to see if they have any information.
I was under the understanding that the blocked lower river was the only thing preventing the plant from running. But I’ve been wrong before.
I saw the original Poseidon Adventure in the theater. A few (dozens) years ago. Good movie.
