Oroville Update 18 Oct IMPORTANT The 2017/18 Ops Plan |
|
Back when this debacle started, there was info posted about what the original maximum water level was to be.
Back when it was designed as a flood control dam and not used as a water storage dam. It was raised to the 850ft level when? |
|
Little bit of snow in the highest parts of the watershed this Thursday.
no signs point to a dry winter. |

It was raised to the 850ft level when? View Quote I'm guessing running it as a storage dam started in the 80s with their big drought, after the aqueducts were built to pull from Hoover dam/Lake Meade. If they plan on actually using hte spillway this year it would be rather foolish, as they know it's going to be the same or wetter than last year from all predictions so far. Next year they are rebuilding the concrete at the gates, so why wait a month to start if they can keep the water from touching them all winter? Last year filled it from 724' to > 901' in a few months. This year should be similar. So it was good news when Mr Browne said they were going to run the 5 operational turbines year around and use the original RVOS system as needed (now that it's not broken). and try to keep it at 800 feet. Usually 70%-75% is 'capacity' for a flood control dam, and that's not much elevation really, when you realize it's filling a pretty steep walled chasm. Hope they trained everybody on maintenance, as well as at the other dams, since this seems to be a common theme there -- Wait til it fails use the attention and emergency money to fix everything like at Folsom. |

That dude REALLY needs to learn how to do noise filtering, or at least cut off subsonics before posting his vid. Couldn't hear shit from everything rattling due to the subwoofer making me feel like I'm standing there. Very distracting, and their voices were drowned out. Phone video?

Did you watch anything more than the first few minutes? We should probably compare your video production to this one to see whose tour inside the spillway is better. Could you please post yours for us? View Quote View All Quotes View All Quotes Quoted:

But if he had time to overlay his logo on there, should have been easy enough to sample background noise and have the software cancel it out as well. It's video editing 101. |

They just got done ripping trenches across it, either for aeration, or to make the "erosion resistant" RCC stick to the base layer. View Quote |

Quoted:
Doesn't appear that any of the rain made it down to the dam area. Once the rain hits that area, working conditions are going to go south pretty fast. I can't imagine what the roads and hillsides will be like, let alone the sloping areas of the spillway itself. I've been on the safety end of big projects and can tell you first hand that the safety people have many many sleepless nights worried that they may have missed something that could cause someone to get hurt.

nice time lapse here. watch the spillway grow up the hill

From the looks of the live feed, it appears that they are at the bottom of the upper spillway retainer wall with RCC.
ETA: Will be interesting to see how they lay down the next layer of RCC with the "magic sauce" within a week. |

View Quote The Gorge is officially filled, now they've just got to get the RCC up another 5 feet to match the upper spillway concrete elevation. I don't know what they are going to do for the RCC wall at that last 20 foot gap once they do match the elevation. Lastly, those disloyal bastages are now using ShopVac® contractor yellow top vacuums instead of/in addition to Orange top Rigid brand vacuums for detailing the cliff prior to adding concrete. |

A question for the heavy operator and construction types: there is a heavy crane still on the upper spillway and it appears that it's not going to fit between the upper spillway and old spillway sidewalls. How will they get it out of there? Run it down to the RCC and drive it out there? How long does the spillway concrete need to cure before it'll handle the weight of that crane? Remove the boom and counterweights before driving it down there?
Inquiring minds want to know! |

Tracks will come off in the turn table. If needed they will pull the drums off the main body. And the turn table off. |

Are they still able to use the dam gates to access the roads behind the dam? If so, will the crane minus the boom fit through?

Just leave it obviously. Remember the kiddy story about the old steam shovel that dug the basement and ended up staying there?

Track cranes aren't designed to move far. Nor fast. A typical pick and carry might be a few feet. Perhaps a hundred. At most. The problem is they have to be on extremely stable and secure footing. As even empty they have a tendency to tip over. (Thus how wide they are.) However, they're designed to be taken apart and put back together. A good crew will have those cranes apart and loaded out in a day. |

That is amazing. I never thought they would make it with getting the RCC section linked up to the original spillway by November 1. October 24 and they're mating the RCC to the old section and are almost done with the RCC work. View Quote View All Quotes View All Quotes Quoted:

The time lapse of them putting down the erosion resistant topping should be a hoot to watch after staring at the slow going to fill the gajillion cubic foot plunge canyons at 1 foot per day. It'll be like Turbo mode, relatively. |

The big crane that is to the right of the lower spillway was assembled on the roadway just below the RCC plant. They drove the completed crane down the dirt road and up to the pad where it's sitting now. I obviously wasn't there but saw it on the live stream. Don't know about the people there, but I had a pretty high pucker factor going on as that thing was moving down and then back up Croyle canyon. I suspect that there were more than a few on site that had the same feeling.

I would like to see some pictures of the equipment from when they started to what they look like when this is done.
