Looks like the Oroville Dam in Calif is getting ready to crack open,sounds like its going to be a real big flood.

Supposedly the spillway is failing at the bottom.
Regardless, all of Yuba COunty has been ordered evacuated. Collapse may occur within the hour. If the spillway goes, it can easily erode over into the damn. Regardless, the collapsing spill way can be as bad as a collapsing dam.I'm about 70 miles away as the crow flies. Not in any danger.

First time the reservoir has filled to capacity and has over toped the spillway since it was built nearly 50 years ago.
And the rushing water washed a big chunk out of the concrete spillway.

Yeah it doesn't look good. My great grandmother's house is only 4 blocks from the river. Hopefully it makes it through. It has been said that if the dam had a catastrophic failure, there would be a couple of feet water all the way to Sacramento (70 miles away and probably 40-60 miles wide valley).

What I heard was they had another Dam somewhere they could open to releave the pressure but right now they were avoiding using that. Because of so much drought over the years they were trying to accumulate as much water as they could.

Kinda sad they have been hoping for rain and snowpack to fill the dam for years....when it rains it pours in California. Probably some nice tractors are going to get destroyed...

Last time I was at the Oroville Dam (1964), they were still building it. Tallest earth filled dam anywhere - 1 MILE wide at the base. Water goes to irrigation in Hemet (long ways south). Hope it doesn't fail.
It is failing midway up. 45 deep, 200-300 feet long, 100+ft wide. That is the main spillway that is normally used.
Now the emergency spillway (made of rocks, dirt, no concrete) is eroding and there is a 30' high section that is in danger of failing. Though report currently is that water is at 901.02'. at 901 it should stop going over emergency spillway which will alleviate a lot of worry. Currently working on filling bags with rock to reinforce dam erosion.

11 pm Just heard the damn is getting worse.They are trying to drop rocks to fill crack.
News conference just said no more water over emergency spillway. They are shooting to drop lake 50' before next rain storm on Thursday, if normal spillway can take it. Releasing 100k CFS and input is only 40k, do they are gaining on it. Plan to assess damage at day light and shore up what they can with helos and bags of rock.
There is No dam above the Oroville dam that would help. I live
35 miles as the crow goes from there but 2000' feet higher in elevation.
We have had a lot of rain so far this year (65") but I have seen a lot more in the last 70 years that I can remember.
This once great but now goofy state needs to put more resources
towards the infrastructure and none for things like the high speed
train to nowhere. But what can you expect when we have
a governor named Moonbeam.

They could have hauled in all kinds of concrete and re=bar when the spillway hole was still small.

What people don't realize is the force behind water such as seen herein. That bridge may fail if that turbulent flow continues like
that.....anchored in rock or not. If I were the Cal. Hwy. Dept. I'd close it till the water stopped, dropped to a reasonable level and the
structure was inspected. Course it may have been built to withstand earth quakes and it does look pretty sturdy and that surely will help.

This sad!
OLDSEABEE is right when the liberals could fix it they didn't the desire now they'll to steal someone else's river.
Reminds me of the story of the appillalation (sp) mountain boy with a leaky roof on his cabin. When it was raining it was too wet to fix and when it wasn't raining it wasn't leaking.

Yep,
Moving rocks with helicopters is not very efficient and I doubt if it will make any difference.

nnalert is already getting blamed for this. Just caught part of what was said but they were blaming nnalert.

Well you know who is getting blamed for this.Caught part of a conversation blaming you know who.
I've been reading the book on the building of the Hoover Dam back in the early thirties. It helped me to understand the force behind the water when they get allot of rain. That was a real feet of engineering in its day. If the Oroville Dam was built after that it seems like they would of done a better job and kept up with inspections and repairs. I supposed it wasn't designed for the amount of rain they have been getting out their though.
When the subject of dams comes up it reminds me that one should read Cadillac Desert. It discusses many of the dams, mostly in the west, built by the Army Corps of Engineers and the Bureau of Reclamation. It is another story of government run folly. Not that all dams are bad. It is worth a look though.

I read that after reading about it on YT. The problem is the book predicted the west would be out of water by 2000. It was written in the early 80s . The history part of the book is great as I had never heard of Jedediah Smith.
Oroville Dam was built by California Dept. of Water resources, completed in 1967.
As a former employee of the US Army Corps of Engineer(30+ years), I can unequivocally state that the Corps has never had a dam that they designed and built fail. Bureau of Reclamation has had several failures, however, most notably Teton Dam in Idaho about 20 years ago. I will readily admit that the Corps of Engineers has their problems, however dam failures have never been one of them.

It's not fair to blame the governor or the CA legislature for not maintaining the dam properly. They Have had their hands full with other, more pressing issues.

While this may be true about dams; I do not think you can say the same thing if you call it a levee.

Yea they gotta get to the important things first.
True enough, John. Especially the Mississippi River levees. But they became a political issue many years ago. I know that the Corps virtually begged for funding for those levees for decades and they were always refused funding. Congressmen of all political persuasions share guilt for what transpired. However, some of those levees never should have been built to exclude the floodplains in the first place. Like the old saying goes, "You don't mess with Mother Nature."
