The Oroville Dam is the highest in the nation.
I did a lot of building on the north side of Sacramento. The levees in that whole area of California are a joke to me. I spent most of my life in Kansas City along the Missouri and Kaw River. We learned what bad levees did in the 1951 flood and in the ‘93 flood.
California has neglected this just waiting for a disaster so that Federal money will come fix it.
If one was a prepper.....
Yes and no. The lake’s 6 inches above the edge and will be down to even in about three hours. Problem is the spillway’s 30 feet high, and it’s unknown how far down it the erosion is. If the area of erosion breaks through at the bottom, the top 30 feet of the lake’ll flow through. Getting the level that far down’s going to take days.
Thanks - I'm just thinking that as the soil under the concrete erodes, then there may be a big hole soon between the lake and the land below. That hole will erode to a huge passage if it happens.
ps. IMHO, they are getting ahead of politics.
What about that top left in the pic you posted and was circled in red? That’s more worrisome.
Sounds to me like there will be some good placering on the Feather river come May or June...
Kinda like there was on the Tuolomne after the floods of when was it, 2000?
LOL
Exactly.
Yeah, exactly. The design spec for the damaged spillway is 250,000cfs and they cranked it up from 50,000 to 100,000 about two hours ago. Guess we’re going to find out what the spec is with a big sinkhole in the middle.
If this dam’s only 30 years old, why isn’t it hydro with multiple gates, like 8, with turbines? My dam, Mansfield on Lake Travis, was completed in 1940, so the technology existed.
It only gets worse.
Dumping boulders will go the same path as that concrete poured a few days ago.
This is bad.
How much more do they need to drain it. ? Is that the 30’

Discharge from the turbines is possibly blocked by the debris from the spillway failure.
Priority will be to clear debris from river channel as soon as is possible to allow turbine flow again.
Turbines are currently shut down.
Anyone remember the Baldwin Hills dam break in the 60’s?
The mud pushed by rushing water is like quicksand. Cars are pushed downstream destroying buildings.
I’m sorry for the good people of California, whatever their politics. This event is not a natural disaster. It is the result of ignorant holier-than-thou overlords who’ve been working the system without opposition like Chicago politicians. Reds, nihillists, destroyers.
Don’t believe that crap!
There’s more weather and snowmelt on the horizon.
This is a months-long event.
The no-fly zone extends to the end of May.
Good question. It does have a power station incorporated in the design. They increased flow through it a few days back and it caused so much debris flow downstream that they had to cut it back again.
Why no maintenance when there was no water?
Union was just making money
