Will be telling in their confidence of the spillway to see if they open it up any more or not. That gunnite or whatever it is that they were pumping on to a few truckloads of rocks at the base of the E spillway is going to last about 10 minutes before it gets washed away. They should have made better time of their efforts by actually placing explosives at the base of that E spillway and blowing it . Once the water level surpasses the top of it that barrier is going to be gone in short order and the pressure release is going to be huge The Dam may be saved just by this measure, it will probably be the only structure standing but the authorities should have evacuated everybody down stream that is in harms way 24 hours ago. Instead they are setting themselves up for a catastrophic blowout that can cause an enormous flash flood at 3 o'clock in the morning. Call me a chicken, but in an event like this I would rather err on the side of caution rather than search for bodies downstream. |

If they dodge the bullet this weekend they will still have to keep the floodgates open to draw down the lake for the next storm and rain runoff.
Does the lake have any other places they could place pumps to send water down another waterway or is it all impounded by rock? |

its pretty clear at this point they do not want to take it above 65kk cfs. if they don't that thing is going to top out here tomorrow morning They're not just thinking of the spillway, they're also thinking of the downstream consequences of the release. There are lots of bridges and dams that appear to be close to maxed out right now, when flow is 65 kk cfs. Double or triple that, as they are gonna have to, via the main spillway, or just wait till the Espillway overflows, and outfall WILL match inflow, and downstream is gonna be fucked. Just look at the videos from the plane and the helo posted earlier, and add in all the debris that is gonna pile up on those bridge supports, and control gates on the smaller dams. The other thing that is happening is that the Feather river upstream to the turbine outlets is gonna be absolutely blocked up with the initial debris coming down. The turbine house is flooded now, because the water is backed up. So looking forward, the ONLY water level control is thru the main spillway. there is no way to drop the water level below the main gates, if the power house is shut down. Well, I suppose if there is a way to open the turbine flow valves, water will find a way to get downhill, especially with the pressure available there - 770 ft of head, = 370 psi +/-, that will just about move anything. But, they will need a secondary outlet, to drop the water level below the spillway, to be able to do repairs. Basically, things are gonna get very fucky in the next few months, dealing with spring melt and runoff.

That concrete wall is not a "plug" it's a weir and is not designed to "go away". Water cascades over the face and energy is dissipated when it impacts the apron (thin strip of horizontal concrete at the bottom of the weir) then is flows down the emergency spillway channel which is much wider than the primary spillway and therefore has much less velocity (at the top anyway) and will erode much slower if at all. |

I am purely speculating here and I have no idea what I am talking about. But I believe they are not opening the spillway, specifically for liability. If they open it up full bore, California is held accountable for the damage downstream. If it goes over the emergency spillway they can claim a state of emergency; and they can get a check from the fed.

Pumps?
Not any that big. If there were they couldn't haul them over the roads, they would crush the pavement. I suspect we'd need the Shuttle transporter to bring them in on a divided freeway and there is none to that dam. Like the comments on Flex Seal and tarps and slip and slide - the scale of this is either too large for some to grasp or they aren't as good with humor as they think. 
As mentioned earlier, it could resemble a mini Grand Canyon event where in a limited amount of time the water cuts a channel in the river and moves all the loose material downstream for miles. The issue is how badly will it do that to the existing valley, and how far? Uncountable tons of material are going to wind up depositing in a fan downstream and it will likely be so large there will be no cleanup. It will be left as is - just the same as some of those previous videos show happened. It keeps getting asked what happens when the surge hits the smaller dams downstream and it would seem the more difficult answer is they get washed out, too, adding their volume to the problem. |

Quote HistoryQuoted:
I disagree. The Espillway is 5+ times the width of the main spillway. The lead up is shallow compared to the spillway. Topping the Espillway is like water sloshing out of the top of a bathtub, whereas the gated spillway is like the drain at the bottom, pulling water from the bottom of the channel, Look at the pics during the drought to see the different topography. I appreciate that however things are getting worse. It's like an abscess tooth that is infected, don't drain the poison and it could kill you. The effort at relieving the pressure has failed and drastic measures must be taken now before you lose the patient. Drought has absolutely nothing to do with the cavity that caused this to happen, the situation is real and it's happening and a clove is not going to fix it. |

For those interested and those earlier in thread saying just to fill the hole with concrete. Each section visible in the spillway earlier are approximately 45' wide by 10'. They appear to be 3'-4' thick. At 3' thick that is 50 yds per section, at 4' its 67. A concrete truck will hold 10 yds.
Using one of the first pics approx 10 sections are missing. Thats 500+ cubic yards of concrete, and thats assuming the big ass hole isn't there. That hole is easily 20x the cubic yds of the replace estimate. So, Just the messed up sections = 50 trucks, 500 Cubic Yards, $75000 for just concrete. To fill = 1000 trucks, 10k cubic yards, 1.5 mil for concrete. Price is for my AO and just material, no delivery or labor. Measurements using google earth and a ruler to scale. Holy fuck thats alot of concrete either way. No doubt it is 100x worse than the photo I used. Post with Photo I used to guess area and other shit other than google earth. Quoted:
Now that's a fucking hole
