the logical answer is to build a true aux spillway over at the hill by the parking lot. They could complete the spillway and connect to the lake during low water. Then they could repair the original spillway at leisure. View Quote |

I have not read any since they started dropping bags of rocks with helicopters. Have they cut the spillway flow to get a photo yet? Any other excitement since the (first?) evacuation? |

What about a ramp to cause the rushing water to jump over the damaged area of the main spillway? How about we do not give them another excuse to run the dam up past flood control level when they already think that is fun? |

I'd like to get back to my life. OP, could you update the title when the n.ext failure occurs or the level gets to 895 or so? This is the best epic thread since Herby Curby! View Quote What? Why do you get off easy? There's over 660000 people watching this. Tune in Sunday nite. It only takes a minute. Of course, then you drop into the middle of the conversation, have to back track, start catching up, then you notice it's 4 hours later and you have to get up in 3 more hours. You're doomed, ya know. It's like crack coated carmelcorn. It's already altering your conscience, and all you've done is post a plea against it worming it's way to the to core of your mind and taking over. Soon you'll realize you've been up 48 hours and the boss thinks you're a no call no show while your wife (or mother) is screaming at you while you pound the keyboard with bloody fingertips as you calculate the inches of rise against the inches of rain desperately paging back and forth from early page to page trying to understand the calculus of watershed vs impoundment ratios and who would be the most likely to order this disaster not knowing it's been a wet winter and just the start of the spring runoff with 7 major cracks in the bedrock funneling water into schist folds forcing them to spread hydraulically and wedge open even further in a geometric acceleration of horrendous proportions allowing the entire emergency spillway to completely tip over right down to the river bed exposing 200,000 innocent men, women and children to a massive wall of water filled with broken rock, trees, cars, buildings, and concrete in a titanic blender of incredible power destroying everything in its path down the river past Sacramento into the Bay and then in a towering wall of hurtling mud destroying the Golden Gate leaving nothing more than stubs of concrete that are swallowed up in the cataclysmic earthquake of California sinking into the Pacific.

That comes from the operations manual IIRC. Some body will correct me if I'm wrong. It is the ideal level for flood control and water storage. The assumption being the hydro is running and spillways set according to pool height. It was announced they were going to be down to 850 by now but that hasn't happened.

where have you seen that they've tried to maintain at 850 ft? That comes from the operations manual IIRC. Some body will correct me if I'm wrong. It is the ideal level for flood control and water storage. The assumption being the hydro is running and spillways set according to pool height. It was announced they were going to be down to 850 by now but that hasn't happened. Yeah, 850 was announced several days ago but completely impossible in the time frame they gave. Because of the drought they have been trying to keep it as close to 850 as possible so the feds don't yell at them but they will let the lake fill up a lot higher than that during "floods" and then slowly draw it down. I've seen the peak elevations posted here for the last 7 years or so and it went way above 850 each year, yet last year was the only year they opened the spillway. In the one report last year they said they opened the spillway up to just 6,000 cfs and that is when it tore holes in the spillway. It would appear no one thought to do a complete inspection of the spillway after 5 years of not running and the first time a light flow does go over it the thing crumbles. Nope, they just slapped a couple patches down and called it good. The epitome of how state workers operate. |

Het Profryan, are you still itchy? Take showers that are as hot as you can stand. You won't believe how
good that feels when that hot water hits the affected area. It is addictive. |

Various articles dated before the recent events. The 850 mark is where they are required, not that they have been following it, to release water.

They dropped outflow to 80k CFS 4-5hours ago. http://cdec.water.ca.gov/cgi-progs/queryF?s=ORO |

First I would rip out the old Emergency Spillway. Then I'd dig/blast down ... to and then good bit past fresh non fractured bedrock... then re-pore the ogee(new term for me) weir all the way to the hill... maybe put another concrete tower there at the height of the dam 922... for the road to go over to access the parking lot. Then I'd finish out the down hill side into a real concrete spillway... putting the road as a long bridge over it... or maybe re-routing it so it's lake side of the weir...

In between the concrete patches is... The same kind of rock that water ran through. Will the water not simply cut between the patches?

Sierra club or whoever it was is going to get their concrete spill channel. It also looks to me like they weren't ever worried about this storm system, if they were they'd have started at the weir. |

Some history of the dam The bucket wheel excavator (shown bottom right) was built by the company I worked for in the mid 60's. More history View Quote Interesting information. Were you involved with the tear down and relocation? That Krupp bucket wheel excavator system ended up at the Centralia, WA coal mine where it was used for about 25 years or more for pre-stripping coal seams. It was used in 2 different pit areas as I recall. I started work at the mine when it was in the second area and spent many an hour keeping it maintained and operating. |

was hoping for some pics of the dredging work... or some new aerial shots...
Oh well album updated with CA DWR's latest pics. Really just the one pic of the work at the Emergency spillway is of any significance. And Chokey already posted it. |

Yah, I agree, that's probably what will actually happen. But how cool would it be to see that spillway launching 100k cfs off a ramp down to the river 400ft below. View Quote My guess is that a ski jump at the current break in the spill way could be a temporary repair to the main spill way that would enable them to build a new spillway. I'd think that the time to construct a temporary jump would be shorter than the additional excavation and potential blasting work required for a complete new spillway. The other thing I was wondering was the auxiliary gates near the e-spill that were never finished. With modern equipment I wonder if those could be connected as a new diversion tunnel. The challenge there would of course be figure out how to do it if the lake levels are above the inlets. |

there is not a dam thing wrong with the Espill as it sits. Build a new auxiliary spillway next to the hill so the original can be repaired View Quote It needs to go deep and get keyed into the good rock down there... and you aren't getting down there without removing the old one first. Building a temporary emergency spillway while you replace the current one seems like wasted effort... just repair the bypass tunnel and use that for emergency situations while you replace the Emergency spillway. |
