The Oroville Dam is the highest in the nation.
This photo is from Feb. 23rd and has the caption:
“...reduction of the outflow from 60,000 cfs to 50,000 cfs
in an effort to support debris removal from the diversion pool
at the base of the spillway...”
I have not found info any more recent than that.
Me neither. I suppose that they can do ‘some’ clearing, but there will be a time when that downflow must stop in order to dredge and clear right at the bottom of the spillway.
Since I’m fully obsessed with the event now, I’d like to see daily progress reports and images. This kind of thing is fascinating to me.
The local guy (Juan Browne -reporter doing news youtube updates) had said that the barges were staged near the power house, but they were waiting for “conditions to improve” (main spillway runoff driven - they need lower levels of flow before they can move/operate the excavation barges at the debris dam).
He describes a number of interrelationships that DWR is managing to get to this goal. (report was from the 21st).

Thanks for the article.
Good people.
re: redirected funds... I suspect there will be new revealing information that comes out on all of this (what was known, why it wasn’t done, what wasn’t known,.. and the usual deflection(s) in answering).
In engineering, it is easy to identify someone who knows what they are talking about. The intense repair work being done, how its done, where its done, and many other engineering aspect driven items are all creating “sources” on the real situation and any past knowledge. I believe that anonymous leaks will happen if the truth is obfuscated.
Activity on the far bank = good to see!
That’s a wonderful story about the Brooklyn Bridge. I think maybe in those days there was a greater commitment to quality, safety, and value of human life than there is today.
Another fascinating bridge story is the conception, engineering, and building of the Golden Gate Bridge. The project was so stressful to Strauss, the Chief Engineer, that he died before the bridge was completed, not because of the technical difficulties but mostly because of the politics,
The void carved out is huge. I read that the hole is 20’ deep. That’s going to take a lot of engineered fill.
That might be a strategic dumping location for rock - if that is their strategy.
This location is the highest of the erosion seam going through and down the other side of the blown out spillway.
Given the size of small houses of the rock at the end of the spillway aerators, the power of the flow may wash away fill attempts if they can’t keep the spillway shut down.
Have you seen any of the videos of loaded rock trucks crossing the main spillway bridge? They are creeping very slowly. This is indicative of minimizing stress vibration/flexing. I wonder much wear & tear the spillway bridge can endure - especially considering the tremendous volume of rock needed to even attempt to fill this erosion canyon using large rock.
Interesting - thanks for sharing.
Maybe the rock could be brought by barge across the reservoir and transferred to trucks in the parking area.
Good stuff. Thanks for posting.
A tunnel through the middle of an active volcano? Hmm, not too sure about that one. I guess part of the next eruption might spew laterally like a horizontal spigot spewing molten lava. Wouldn’t want to be in the way of that one.
“The intense repair work being done, how its done, where its done, and many other engineering aspect driven items are all creating “sources” on the real situation and any past knowledge. I believe that anonymous leaks will happen if the truth is obfuscated.”
I certanly do hope so. Certain people need to be held to account for endangering lives and property to push their progressive agenda.
I think that basin carved out is about 3 times that deep. Remember that the width of the spillway is almost a football field in width. Think of the spillway as about 15 sideways football fields and your scale adjustment will be about right.
60 feet deep?
3 pm California time on Feb 25th
Inflow 23204
Outflow 50076
Lake Level 845.36
I wonder if they’re going to back down the flow again soon, or maybe they want to get much lower and then stop for a while to dredge.
32 feet remaining before the spillway will be dry.
Handy, updating chart.
Looks to me like they're going to repair/clear the generators very soon.
The time to fill the reservoir is almost at hand.
