Wow, what an amazing amount of work they have done, but it looks like there's still a long ways to go before she's ready yet. The huge gap of the wash-out canyon looks like it would be impossible to fill in. But I don't doubt that they'll have it filled before year's end, if the weather allows. And THAT is the big problem. |

When does the rain season usually begin in that area of CA?

I hope they finish it and that it holds. If not, a lot of towns will be wiped out.

They got it right, having bottom half meet the deepest RCC coming up, but now that flat ramp with equipment on it and the cliff up to the next concrete gives it a heck of a perspective as to how much crap washed into the river from just that little bit. |

I wonder if they could bridge the huge cavity with piers and bridge-like construction?

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.

Here's a link with climate data. The rain starts in October and really ramps up in November and December, and stays heavy thru spring. That's why I was wondering about washing out the roads and the canyon.

Couple of questions for the construction guys that do this sort of thing:
ETA: Maybe these questions would be better asked on the Blancolirio channel. What does the hive think? |

ETA: Maybe these questions would be better asked on the Blancolirio channel. What does the hive think? The parts they are putting the rebar in are the "Final Product", but that's only in the bottom sections near the dragon's teeth and the existing upper section to the cliff formed, where they've laid horizontal drainage and 20' anchor bolts to bedrock fairly often. No rebar or anchor bolts anything with RCC only. The guys doing the scrubbing and vacuuming of rock in the upper part are making it ready for Dental Concrete, which will prevent the rock from fracturing more. The watery-slurry stuff being poured right before RCC areas is Leveling Concrete (I translated it into "Primer") since RCC doesn't stick to uneven rock very well. There was a lot of info on that in I think parts 2 and 4 of the Big Tour video set Juan did. The only epoxy coated rebar is going in the structural concrete layer closest to the surface IIRC. I don't know anything about epoxy coating concrete to cure faster, though. Everything RCC except for the grade/fill (middle part of spillway) will be ripped out down to just the grade in the spring and then it all gets pretty structural concrete surfaces and walls. For this winter, RCC will be the spillway material for 1/3 of the length of the spillway. So once they have that cliff filled to the grade they want, everything they add after that is getting torn out next year, including all the emergency spillway shotcrete. |

From what I understand of it, all (mostly missing) retaining walls that do/will not have rebar in them will only be very wide RCC 12' tall chunks. They might be putting screen+shotcrete on RCC sides so it doesn't erode as quickly if a big water release is needed? I remember the shotcrete screen overhanging what the water dug out under after the first few patches in March, so it's pretty durable.

The RCC in the plunge pool seems to progressing slowly.
I'm surprised that they are not throwing more resources at it. Is there some minimum time between layers that is limiting them? Also, I was looking this picture and noticed the "guy's" hand.
I was like wtf? Just really looked odd.

https://www.AR15.Com/media/mediaFiles/35314/what_the-309244.JPG So the limiting factor is probably how fast they can make it. and the supplies they can bring in to make it. As each dump is approximately 2.5 normal semi truck loads |
