Anyone in Oroville, CA?

The Columbia river doesn't reach 600k anymore.

Pretty sure that was the Kansas river.

But the Columbia averages 250k and maxed out at well over a million.

[wyeaster]

For shits and giggles, 1993 Tuttle Creek flood is worth checking out. They were letting out 600k and washed down to a 293 million year old fossil bed.

pan that shit for gold!

[capulin overdrive]

Tuttle is on the Blue before it dumps into the Kansas.

Yeah this one's a gem too. Original article is from 2005.

"The concrete weir at the top of the emergency spillway was “just plopped on top of that ridge. It’s a design area that will probably get a lot of scrutiny and had to be a major concern as [the spillway] was eroding up the hill.”

Vogel confirmed that the weir, which she said ranges in height from 25 feet to 45 feet, was not anchored."


This blows my fucking mind.

[LightRanger]

Yep. Totally.

There was also a question about where bedrock was below the main spillway too.

Not much of a question now!

[LightRanger]

Heheheh. Indeed.

They have to be pretty psyched about this break in the storms. I understand they stopped spillway releases yesterday. We've got a decent break until at least Sunday, so time to really hit those repairs.

[Dantheman]

Apparently they are going to try to clear between 500,000 and 1 million cubic yards of debris over the next five to seven days so they can reopen the power plant. So, 100k-200k cyds per day. That is a shitload of earth moving.

https://www.metabunk.org/oroville-da...h.t8402/page-6 has pretty amazing pics with the water turned off.

Google says the average commercial dump truck hauls between 10 and 14 yards of rock. Let's assume they are going to move 100,000 yards per day at 14 yards per truck. That's 7142 truckloads in a 24 hour period. 297 per hour. 5 per minute.

This can't be right.

I doubt they are using commercial trucks. I'd assume they have a fleet of mining type huge discovery channel show type machines?

[BmillsSkier]

? ? ?

[Game Over]

Wow

[Game Over]

I'm curious if they try to use the water to their advantage and let it help them cut thru it

[BmillsSkier]

That guy's thinking, "we're gonna need a bigger barge."

Where would they come from? I'm not aware of any mines in that area that would employ such vehicles, nor do I believe that the local roads are capable of handling the weight. Maybe they dump nearby, within a few hundred yards or a mile or so from the dam site and run trucks round the clock.

[Game Over]

Good point. Railway perhaps?

[Game Over]

What about just blasting a nice channel thru it? It's going to be interesting to see what they do.

Edit- otoh explosions of that size may not be good for the integrity of bedrock that they are almost entirely relying on at this point.

Thanks for that, some excellent drone footage too. 1M cyds sounds about right for that pile.

It looks like a lot of this may be done via dozers just pushing shit out of the main channel. They probably don't want to actually move all that material very far since it will be usefull fill material for the repairs.

^thats what I was wondering about. Then the water could help make it bigger? I'd assume you'd still have to blow the breech?

Was looking forward to your response. Cool stuff indeed.

[Dantheman]

With everything shut down right now there's very little flow, that area is basically just a lake right now. Also, keep in mind that those little yellow dots are probably D-fucking-9s, and this is the material left behind that 100K cfs couldn't carry away. Water isn't moving any of that.

[Viva]

I noticed those little yellow dots and wondered which model they were. They also are capable of navigating over the pile, so it's either dried significantly, or its rock. Gonna be harder to move than soft earth, I guess.
