[quote=rnovi]Ah, so this picture makes more sense to me. The main spillway had damage. The emergency spillway then cut into the main spillway exacerbating the damage. That's bad...really bad. ![[Linked Image]](http://i83.photobucket.com/albums/j288/rnovielli/Screen%20Shot%202017-02-13%20at%208.19.53%20AM_zpsrmlpyqiv.png) The California Department of Water Resources stopped the spillway flow on Thursday morning to allow engineers to evaluate the integrity of the structure after water had been released at 20,000 cubic feet per second through the night. (Courtesy of the California Department No, the emergency spillway is routed through a ravine quite a ways away from the main spillway... It cut a path back to the main spillway.

A guy might tinpan at the bottom of that and do some good. Might have turned up a few new nuggets. I thought of that, the first I heard of this. Back in, I think it was '86, there was a flash flood event on the Feather River above Oroville. It washed out roads and stretches of railroad track, and even topped over some of the smaller dams upstream of Oroville lake. That spurred a gold rush that lasted at least a couple years there, IIRC. I don't know if any placer miners struck it rich, but judging from all the new equipment I saw in use, the prospecting equipment makers and sellers must have enjoyed a bonus. 1986 Yuba river Levee "broke" in Linda Ca. Some believe it was blown on purpose to save Yuba City.

These arseholes really dropped the ball with the release of information. Water started flowing over the emergency spillway at approximately 8am saturday morning. Local news agencies and "officials" covered the first hour of it then looped the same morning video of it all Saturday and into Sunday. You had to rely on people live stream from the damn to get an idea of what was really going on. You would think that if there was even a slight possibility of the emergency spillway being used(which the officials decided Thursday and Friday wasn't going to happen) for the first time EVER that they would have started to get the word out to start moving away. Instead they start running around with their f ucking heads cut off shouting it's going to fail in an hour, get out of town! Talk about a Cluster f U.K. To the umptenth degree. Heads need to roll. Piss poor management. Piss poor delivery of news. A lot of people got lucky last night.

Looks like it may have failed from undermining. Percolation from the earthen dam created voids under the slabs.
I think you underestimate the power of moving water. I think that a lot of other people who are responsible do too.

Main spillway. Couple of days ago v. today. ![[Linked Image]](https://pbs.twimg.com/media/C4Pu7EPXUAcwPiV.jpg) It's abundantly clear that the failure began at a seam in the concrete, where I would bet anything that the seal had been lost and water intrusion has been allowing the rebar to rust. Years ago, I was involved in a whistleblower event regarding a bridge that was on the verge of collapsing. My voiced concern was blown off by the controlling authority initially, with explanation that fractures in concrete were not a problem unless rebar was rusting - and rusting rebar would have to be evidenced by rust stains streaking the concrete. My follow-up photos showing the rust streaks, along with threat to go public when the bridge fails, drew immediate and dramatic positive response. I'd bet that the photo posted above from 2013 shows when crews were out there looking at rust stains. Makes me wonder what else might not have been reported or dealt with. Looks like it may have failed from undermining. Percolation from the earthen dam created voids under the slabs. Did you see the some of the faulting lines in the over thrust in the formation immediately below that hole ? Percolation dittos, with a probable grout curtain problem contiguous. GTC

So, is it going to fail right now?
Or is the danger over until more storms?

I think you underestimate the power of moving water. I think that a lot of other people who are responsible do too. This is the principal behind "Digger Dams", which I will be using on my hunting property hopefully this spring. Cut and leveled tree trunks, set into the slope, cause the cascading water to dig out the downhill side. This creates ponds. I hope to have 4 or 5 in series in the same gulley. This will privide standing water for game, where there is now only watershed.

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.

But my point was more about how that hole didn't need to be there for hydraulic forces to rip away the concrete skirt once the rebar had failed.

I've yet to SEE any rebar, myself.

Looks like plain concrete slope paving. Probably has wire mesh...
Done quite a few channel linings that way.
