I cant copy and paste anything from the article... Probably some way around them disabling that function, but you will just have to go read it on their site, but there is a ton of new images now that the flow got shut off on the main spillway.

Excellent footage, thanks.
From our local paper today. http://www.orovillemr.com/general-news/20170227/oroville-dam-operators-stop-flow-down-spillway-see-extensive-damage?source=most_viewed
We never evacuated as we lived above the dam. It was pretty harrowing though as us folks that stayed behind couldn’t get any food, etc as all the stores were closed for miles around. There was a market opened at Lakeside, but they couldn’t get any deliveries as roads were closed.
While our experience was nothing to the level of those that experienced Tornados or Hurricanes or actual floods, it was still something to think about.
Gov wants money from the Feds to fix the damage. Why did the state vote for billions for this very thing? What a mess and us locals are none to happy about it.
From our vantage point below the spillway we see the sidewall and slab failure allowing the blowout of billions of pounds of water that have cut the new canyon.
Moonbeam Canyon, a spectacle similar to many items in the legacy of the Democrat party to the Golden State.
I was expecting it to keep eating its way to the top.
Hundreds of thousands of tons of dirt and rock now going downstream in the river below.
Our relatively new RiverBend Park is now toast thanks to the massive release of water. Real Estate deals have gone sideways, what few companies we have here in town lost money and employees lost wages. What a mess. As the Gov says...”Stuff happens...” What a schumeel.
“Moonbeam Canyon”
How can you make it official and get the H out of there.
Leave it “as is”...down to bedrock already, and looks more “natural” now. ;-)
amazing the power of water under the force of gravity. just a few days of spill way water and a new canyon is born.
The slabs of concrete were not thick enough to handle the pounding from the water. It looks like California wanted to get by with the least amount of material to scam the tax payers.
I think I spy a snail darter ...
Ultimately, I think that’s right. The scale of this thing is amazing. Maybe it was just a liiiiiitle underengineered ... just to save, you know, a coupla million ... and now ...
thats why hurricanes are so dangerous...you simply cannot estimate the power of water...especially salt water. These fools that ride out hurricanes are just asking for it.
There has got to be Delta Smelt down in there somewhere! ;-0
It appears to be unreinforced concrete, that just seems insane to me in a state with that much seismic activity.
Concrete cracks, plain and simple, then you put that much water over cracked concrete and this is a fairly obvious result. Especially if fill washed out under the spillway over years and the unreinforced, cracked concrete was spanning over voids.
One liberal state’s engineering disaster; alternatively a really cool challenge for Evil Knievel!
:-)
I ask myself, "Why did it fail in the first place?" and "Why did it fail again in the same spot?"
My hypothetical answer is that the location just below the fall-off of the chute causes increased stress due to cavitation, or what have you, and it failed the second time ( after the repair ) for the same reason that it failed the first time ... faulty design!
