Quote HistoryI've got no clue if they are slowing down so everything comes together with perfect timing at the end, or if they are running out of suitable on site aggregate for the RCC. Hopefully we'll hear from Juan on those details. It seams they are planning on spraying the shotcrete or epoxy concrete on the sidewalls in pretty much one go, the way they've left the horizontal scaffolding up after they've bolted the mesh to the RCC wall. Somebody with more concrete work knowledge may want to correct my assumptions here. They're putting a lot into stabilizing the RCC walls, which will be torn out in the spring, I'm guessing with all the anchor bolts they used as well. |

A lot of the bridges over the lake were very high bridges across little streams way below that had't yet got to the lake. Huge martian like valleys completely barren. Quote HistoryQuoted:

Anybody know the lowest the lake got during the drought years?

You'll know Oroville is low when people start posting photos and videos of the old railroad tunnels covered by the lake becoming visible again. This photo is from the peak of the drought in 2014. https://i.ytimg.com/vi/f-Rg7l7daOs/hqdefault.jpg Quote HistoryQuoted:

I really enjoy seeing construction guys doing just that, large scale construction. Infrastructure projects like this are awesome, not only in scope, but just what can be done with enough resources and ingenuity.

It looks like preparing the RCC is the bottleneck. It was going faster than I expected at first, but now, even with the increasingly smaller area, it's going at the speed I originally figured it would go, which is about 1/4 speed of how it started. Used to be full dump trucks of RCC were in line waiting to dump, and there were 3 bulldozers, now it just seems to be going 1 truck at a time with 1 bulldozer and 2 steamrollers. I've got no clue if they are slowing down so everything comes together with perfect timing at the end, or if they are running out of suitable on site aggregate for the RCC. Hopefully we'll hear from Juan on those details.

I wonder why we haven't seen any good dive videos of the towns that were flooded from filling as well. A couple should be shallow enough to go see, as long as they don't get anything between them and the surface. There's several old houses and Old Forts flooded by the Oahe Dam filling that are amazing dives to go and see, most dams have some hidden nuggets that are preserved like that. My brother got an old cannon from a Fort that was going to be overfilled with mud from nearby construction. It's not a large one (2 lber?), but he built a mount for it and displays it along with pictures of the old fort. Can you get a few pics? |

Some old B&W print photos of what was above water on the old forts, didn't have dive cameras in the consumer range back then (70s-80s). I don't know where those are in my house, though, other than in the photo boxes, which narrows it down to only a few tens of thousand pictures I haven't sorted yet.

 Oroville Update 20 Sept. 40 days to go... Juan update 
So due to the size of the area they are trying to raise they are only going up on average 1 foot per 12 hour shift. As they get closer to the top the area needed to be lifted will decrease and they will be able to lift more per shift. 30% of the structural concrete is in place. Hardened RCC (which will be replaced next year with structural concrete) won't get put in place until all of the base RCC is put in place. 50% of the plunge pool is filled (75 feet to go) |

During Juans' last update, he mentioned that were taking down the shoe-fly connection above the upper spillway today. Should be interesting to see that as it happens.

I believe he said it was coming down Friday, so it should be down already. Looking at the top of the spillway camera it looks like it is.
ETA: Are they going to fill the trench at the top of the bottom of the RCC with Hardened RCC? |

It is spelled both ways on different Lineman's Slang Dictionary and industry news (shoe). The Official Lists show shoe-fly, but the news reporters on other ones spell it shoo-fly. Though one list from a different electric supply company did have it as shoo-fly. Example, some funny ones in there Clearly, it's more of verbal, but I'd like to know the origins of the term. Maybe we can get Juan Brown to look it up for us.

They are literally filling that giant ass crater with nothing but concrete. That is a lot of concrete. Should the surface erode this time, it's going to take a long time for the water to hack that away.

Quote HistoryThey are doing this one right, combining everything we've learned from this and other dams/spillways, and applying to to make it pretty idiot proof. As long as they do dredge it every time there's much sediment that comes over, and they inspect the entire new spillway in spring and fall. That's not going to fail again. Now, about Shasta...

With that dredging going on the entire time the rebuild has been in progress, that river bottom has to be looking like the grand canyon by now. Or, at least, a deep quarry where the spillway waters hit, so it has room to do it's turbulence thing and slow down instead of hitting opposite bank and eroding downriver.

I'm sitting here looking at all the pictures, reading the comments, and of course I start to think. I apologize in advance for that.
Since all of this construction is being done on bedrock which I assume is pretty solid stuff, what happens to the whole system if earthquake or even just some tremors shake the area? Wouldn't it be better to have some give in the system? I had the same question when I saw some recent adverts for jacking-up sagging foundations of houses. Adverts states they anchor it to bedrock. That's fine but if you get a jolt won't that get transmitted directly to the foundation and the house? |

I did intern at Oahe Dam and studied all the dams on the Missouri system, though (Mostly Earthen). No earthquakes were considered. Got to speak with the guys who designed the dam and learned a lot that was rule of thumb, but proven accurate later via computational fluid dyanmics and stuff capabilities far beyond the slide rules they were built with. There were many failed dams around SD and the nation built by the CCC in Great Depression period, and a lot was learned about structure and failure modes, as well as sound principles, from them. People's favorite hidden fishing spots are often a CCC dam with 193x headstone and initials of workers in it somewhere. The CCC dams and Missouri Engineers are sadly a forgotten footnote in history. |
