As soon as rushing water gets under the concrete the whole mess will find the bottom of the hill.
“They are placing 1,200 tons per HOUR”
How is that possible using Helicopters that carry rock in bags that are rated at a one or two tons?
Exactly. Those are some big holes.
Unless you have flood insurance (most mortgage companies would require this in a flood plane) the payouts are minimal at best. Here’s praying that the rain goes elsewhere.
That much water rushing downstream would be unprecedented.
great closeups and perspective
UPDATE “ROCK SHOT” at Oroville Dam: Repair Before Rain Overtops Spillway Again

Although this isnt a collapsing dam, the outflow would look something like this. Although you can times this by about a hundred thousand.
It will spread out after the intial breach and collect a ll the debris and take it down stream. The debris is what is really bad. After it collect all the houses, trees, mud, cars, bridges and everything, the force behind it will keep steamrolling everything in its path. Then it spreads out sideways and floods since the intitial stream wont be able to hold it since that will be filled with everything of imagine. Basically, it will go where the least resistance is.

They trucked in most of the rock.
So they are trying to dump pebbles into a massive flow. Ya that’ll work alright.
They should be working on the EM spillway in case that runs again. I would have got down there with every GD bulldozer I could find and PUSH the berm out in front of that thing so that water flows AWAY from the spillway instead of collecting into one stream.
Like one other guy on here said. Those pebbles they are dropping into that primary spillway are going to bunch up and restrict flow. And that is exactly what they are dumping..pebbles.
Didnt these geniuses ever learn anything about hydraulics in school?
The main spillway is getting worse and you can see it cutting into the base of the mountain that supports the dam here:

Actually most homeowner policies do not cover floods. It is usually a very expensive optional add-on.

With a huge deductible.

Look at where I live.
I have to have flood, typhoon and Tsunami insurance. It is cheaper here because the building code don’t let you build wood frame construction. Our house has 8 inch thick reinforced concrete walls and an 8 inch thick reinforced concrete roof. No shingles, no carpet and a foundation that is three feet thick
.
The dam is not in any danger at all.
It never was.
It’s all incompetent knee-jerk as far as the evacuation is concerned.
The rock they are placing will protect the main spillway from being torn away from the dam.
A lot of rock was placed by truck. They choppers were carrying bagged stone to inaccessible areas while they used earthmoving vehicles to build a new road that allowed them to backfill and harden the area along the emergency spillway. It’s a combination of riff raft and concrete.
They’ve been very busy.
I think you meant rip-rap. Unless they are picking up some of the riff-raff from LA and San Francisco and laying them out along the spillway! (That has been suggested by other Freepers.)
LOL - spell checker... whatever they can find to plug that hole!
But the rock they are placing is intended to fix the damaged emergency spillway. The main spillway nor the dam itself was never the reason for the evacuation.
