THE DAM IS NOT THE ISSUE

THE DAM IS NOT THE ISSUE
Ever since you got on this thread you have been desperately trying to keep our attention away from the dam. And now your doing your own little doom porn dance about the valley flooding. What gives? Why don't you want to talk about the dam which is the subject of the thread. Why do we have to focus on the flood.
The sac valley deals with floods all the time, there will be some local flooding and then it will dry out and be back to normal. The DAM is the subject if this thread. If the flooding is such an issue start another thread and bless everyone there with your unfathamable knowledge.
Old news? Didn't this happen like 2 says ago?
think harder.. This is now..
OR did you think the lake water level magically went away?
the erosion continued now they warn of imminent failure.
yea?

The live feed is confusing. One screen says it has failed and the other says it could. Which is it?
It looks like it could fail at any minute.. the side of the lake is eroding..
the spill way is a structure that is broken already, but that is not a structure that holds water back..
is that your confusion?
they increased the flow into the spillway to 100,000 cubit feet/second.. Hoping to release pressure to the left of that where the lake is going over the edge of the dam..

Work for the government? Never thought of it till now.
Murder people down stream? What happen to you were pretty level headed but that's ridiculous.
I just wanted to talk more about the status of the dam, spillway and newley eroded sides of the dam in relation to potential seismic activity which Lake Oroville has a unique history with.
But obviously I can't, so....
No big deal. I will say you have been providing some great info and resources, thank you for that.
I hope nothing goes bad on Monday. I live in Sacramento 2 miles from one of its rising rivers (I posted about it in this thread).
Any plans to start another thread about your concernes for Monday?

Can't believe they have people back already, all considered. Ten inches of rain expected now, too - source - which, when added to the snow melt, is quite a lot. Who knows how their repairs will hold up!?
Ah, quake possibilities. Yeah, that has to be considered. I read the dam sits right on a fault line. Great planning, eh??
the conflicting reports on the looting is because there was some crime but it was like individuals no widespread looting or rioting.. Know what I mean? I bet not many even saw it.
This link you gave is data and that's what we need in this thread.
Today there was aroud an inch of rain.. 10 inches is quite a different story.
by let's make this up in my head by this time tomorrow the lake should be 854 feet above sea level, giving it a space of about 50 feet to fill.
I'd have to do some math to imagine if that would be able that 10 inches would be able to fill that last 50 feet and then over top the emergency spill way.
That is a huge danger if it can overtop, but I'm not forecasting that.
Currently we are holding at around 30,000 cfs in flow into the lake.
They are holding the main spillway at 80,000 cfs down from 100,000 cfs.
That still gives us a net drain of 50,000 cfs.. For reference as shown to me earlier in this thread niagara falls is 84,000 cfs.
so look the point of the dam. It's supposed to be flood control.. The danger is in not being able to use it as flood control .. idealy you want to hold water in the lake and only outflow what the rivers can take hoping the lake won't fill up in the process.
because of what happened and the lake being over full they had to just drain it as fast as possible without the ability to consider river levels..
So I havn't checked the other dams in the area like Shasta. I'll do that in a bit. If they all have room then the rain might not make the rivers flood.. but if they all have to release a lot of water it's going to spell trouble and at the moment the trouble is going to be further south than near the dams.

I didn't claim to be an engineer. I did, however, post information from a dam engineer who is concerned about this dam, and believes there is a real problem there. Plus, don't act like I am the one who spoke of a 30' wall of water, because I am not. Nor is than inaccurate, for that matter. When a break does occur, you do, in fact, get a wall of water, and the size will be affected by the size of the break. For closer areas, that is a very real threat. Plus, with more rain coming, and with it, snow melt, a lot more water will be in play, and that means there is still a lot of potential for disaster. That they allowed people back in isn't exactly a surprise, either. Whether it was the right thng to do is what is up for debate, and that remains to be seen.
I really hope that nothing serious happens. However, I won't say it's unlikely to happen. I said the same about New Orleans, too. "Gloom and doom" many said. The levees would hold. No storm would hit directly. We all know what happened, though.

Interesting seems discussion related to the Lucifer storms and rain fall does not compute to most people, thanks for your reply.
Here is something I saw after posting my thoughts that was rather interesting.

"Lucifer" storms? Don't know anything about that! Can you summarize the video? A bit long, and not conducive to listening right now, so will have to wait on that.
Some of the concerns are due to the precariously full Don Pedro Reservoir, which captures water from the Tuolumne River, a key tributary of the San Joaquin.
The reservoir, which has more than twice the capacity of Folsom Lake, remained close to cresting Sunday. If it goes over the top of its spillway, it would send a gush of water that could overwhelm the small Tuolumne River channel, flood part of Modesto and cause the San Joaquin to rise.

Here's a link to flooding and evacuation warning not connected to the dam. The photo is about 50 miles southwest of Oroville. There's just a massive amount of water in that area. Very flat along the I-5 corridor. I can only imagine trying to evacuate in a car only to run into roads covered in water.
Also in the article, fear from another dam further south having water run over its spillway, add to river water, causing flooding downstream in their area.

MAXWELL
Forecasters with the National Weather Service offered a stark warning Sunday for just about everyone living in the soggy, soaked Central Valley.
“Pretty much anybody needs to be prepared for the possibility that they may have to evacuate quickly,” said Sacramento meteorologist Brooke Bingaman.
