Quote HistoryIt'll be a shame that, with the current long term forecasts, that the spillway could avoid being used at all this wet season, and the RCC will be ripped up again to replace with structural in the spring. So part of me wants them to manage the water level and keep the spillway dry until it's fully rebuilt, and another part of me wants to see this spillway in "normal" operation, but by the time they're using the spillway, their margin for error is reduced a great deal. Better to keep dumping water and lowering the level more until the rain they know is coming hits, then keep running all the turbines they can instead of wanting it "full" before April, when they'll have to dump it below 800' again anyway for work on the spillway gates/intake/top bit. |

I'm about 100 pages behind in this thread but has anyone mentioned the updated cost of repairs yet? Saw a report on the local news yesterday. It went from an estimated $275 million to...$500 million.

It's its ripe for a Mike Rowe narration. A Technical version used for training civil engineering students to help understand proper maintenance and upgrades on older projects since we can't afford to simply build everything over again. A Technical one that doesn't pull any punches for educating operators of other dams, covering maintenance, workarounds, importance of plans in place, etc. A "Public Version" with a bit of geek info, with 'sensitive information' redacted (blame original builders instead of operators) A "Public Version" dumbed down for the masses. The latter two will make CA the "Victim" of "bad engineering from the 60s" without touching on maintenance issues (River Valve Outlet system broken, spillway never GPR'd until it failed, etc.) I'd really like to see the first 3, but realize I'll only probably get the 3rd version, like what Juan Browne has already put together. I doubt any will be released until the rebuild is complete so they can end them on a high note and 'expensive lesson'. |

The only thing I don't understand is what they're going to do for this wall gap, since they can't build an RCC wall that high without using cranes to lift the steamroller up there as well as dump RCC (though that may be their plan... I don't see a big wall form on the ground anywhere near this spot on either the North or South sides..

Will be an interesting turnaround with concrete production and transport next year. All the product from the RCC plant will now need to go to the other side of the spillway for armoring the e-spillway flow area instead of the more direct and shorter route they had this year.

Wow!!! The have finished with the RCC! The video shows how they've closed the gaps in the walls and the ramp is all connected. Now it looks like some transition walls will be built from the RCC walls to the original walls above.
If you had told me they were going to finish the RCC work before November 1st I would have bet against you. I thought they would need until the last minute to get it done. |

Those transistions from structural to RCC and back seem like an invitation for cavitation damage. Going to be interesting to see how this holds up if they have to use the spillway this wet season.
ETA: I'm amazed they've managed to meet the schedule. Just goes to show what money and enough people can get done. |

Part of me wants to see the spillway in action and part of me hopes they don't have to use it this next rainy/snow melt season. |

I'm curious what that "ramp" is for at the bottom edge of Structural concrete to RCC joint. They have 3 days to lay down about 1 road mile of the Epoxy RCC. They've been hosing down and roughing up the main RCC run for over a week now, I think it's un-smoothed enough to hold for 6 months.

Quote HistoryI'm impressed. I'm also curious what's making the funky color shifts in the "erosion resistant" RCC top layer, it's flat and level, but looks like hell. Maybe it'll even out once it cures completely? The arc swirls are going to be there from the swing/reach of the tamping arm, I don't know what the white/black "runs" are coming from (maybe water above??) If they can keep from using the spillway this year, that'll leave their road at the end intact, and make next year start a month earlier than they'd need to wait otherwise. Plus, lots of power generation. |

Take a look at the live cams. Wall forms are removed and they're finishing up smoothing the last of the RCC. There is a huge tour group there right now and a large helicopter flying up the spillway. Just a few minutes ago, there was a drone doing some close up work.
ETA: Oops, one wall form left on the upper spillway transition. |

If there are ANY reservoirs not generating maximum power possible (save for maintenance turbines) then the director needs to be fired. They should all be at 70% or lower with the amount of predicted snowmelt, it's not like they aren't going to end completely full in the spring if wanted to supply water year around. Managing with breathing room is easier than managing the top 15%, but they apparently finally figured that out Conspiracy Theory: More non-disclosed Neglected Maintenance at other site(s) like Shasta and hoping for a dam to fail for even more federal emergency money to repair and rebuild. The emergency money for Oroville was used to fix the broken RVOS, which was damaged in 2009, but never repaired. Leadership is either idiots, criminal, or both if another failure occurs anywhere. All dams should have been audited thoroughly over the summer. |

Thank you so much Orion for making those albums! Is there a way to download the archive of each album as a .ZIP file? I'd like to keep a local copy for whacky reasons.
Mostly, because it allows flashbacks, like going from "That couldn't get more totally screwed if they tried!!!" 
To today, where there's just a little touching up and equipment removal left. In SEVEN MONTHS!!!

I'm not aware of any batch method to download an album built into the site. I know there are browser add-ons you can get which will download every image on a page but don't know any to recommend. There's always the manual method of right click >>> save as... on every image.

imgur actually paid attention to people wanting that, and it is now a built in feature with an album! How to Download an Album on imgur It gives you a .ZIP archive, and is pretty speedy at sending it (not throttled). |

It's amazing what can be done when the .gov let's people get to it and do their job.
I can believe it's been seven months, if a read every response and have shown the albums full of pics to others. I still become amazed at the true size of this project, I would love to visit this site one day and see the true size in person. |
