That's just the surface, the weir extends down below that. The weir probably has as much height below grade as above it. I am skeptical of that but am not going back to find the cross section...assuming that it is even close to accurate. That rocky area is not what I would consider viable bedrock for use as an emergency spillway. |

Did you see the cross section drawing that was posted about 20 times? What you see is all there is. The sill for the water to land on is even with the bottom of the weir. I'm pretty sure that drawing was just that, a drawing. I'm sure the prints show what was actually done |

Of course that isn't a trivial amount of excavation and construction work to do, but perhaps they don't have to dig all new footings, just dig to tie it into the hill better, and then somehow anchor the new poured concrete to the old weir. Way out of my lane though... Just go to Home Depot and get a box of hurricane ties and really good adhesive. |

At this point of Monday Morning Quarterbacking it is pretty clear they should have never tested the E Spillway. They almost had a catastrophic failure and had to evac 200000. Upping the release of the main spillway and monitoring the erosion of the flume, in hindsight was much safe in the short term. The problem is can the damaged flume of the main spillway survive every drop of H2O in that water shed? Time will tell.  Quote HistoryQuoted:

The spillway being damaged was a bad thing but why on earth did they decide to use the emergency spillway?
Isn't an emergency spillway an absolute last resort, Hail Mary to save the main dam incase shit goes sideways on the main spillway. As in the main spillway won't flow any water for whatever reason. Why didn't they ramp up the output on the spillway and monitor the erosion early on before deciding on the E spillway option? After all said and done, they did ramp up to 100K cfs and the spillway wasn't damaged too much more. Didn't the E spillway only put out 12K cfs. If so, their cost-benefit analysis ration was way off.

Quoted:
You have repeatedly stated that the dam was no longer licensed by the FERC, as of 2005, but there's a settlement agreement for relicensing the dam in 2006, and nothing in that agreement covers anything about increasing capacity, the bulk of it talks about remediation measures for various forms of wildlife (snakes, fish, bald eagles, etc...). License still not issued it has been in the renewal process for over a decade. --ETA: Lawsuits from Sierra Club and others wanting emergency spillway to be modified the way they are doing it today, and others have tied it up. More Info from CA DWR itself on the license problems. Yet when I look, the dam is operating under a year-to-year license issued by the FERC and the only issue preventing issuance of the final license has to do with an aquatic biological opinion from the National Marine Fisheries Service, the FERC staff had recommended that a new license be approved once all of the wildlife management concerns had been addressed. NOTHING about modifications to the structural integrity of the dam or requiring different inspections (provided they were complying with the applicable Army Corps of Engineers standards, however, no statement is made regarding evidence of noncompliance or penalties if such is detected). |

nope, it has to be lower than the weir - or you have a dam. They wanted 1700 feet of weir at 901' elevation. The parking lot is a non-issue and is sacrificial to a flood event. No one is going to be parking there during a flood anyway Tell me how water is flowing from some distance BELOW the top of the weir along the parking lot section? That was clearly visible in about three spots when people were looking at the "hole." |

I've been following this since the beginning but seeing photos that show scale is still pretty awe inspiring. Though saying that, please understand that I know there are tens of thousands of people that are suffering because of this fuck up. This is also an important lesson for engineers that are responsible for the safety of the public. Don't sign off on something you aren't sure of, bonuses or management pressure be damned. It'll all work out until it doesn't, then it's your ass that's going to have your license pulled, terminated, and possibly prosecuted. Or worse than that, you kill people. |

Been out most the day today. Nothing big seems to have happened today which is good. But i have a question that I've been pondering for while. The rain over the watershed is supposed to start on Wednesday night correct? What are the possible side effects of heavy rainfall on the regular spillway and E-spillway? I'm talking about mudslides and further erosion without any lake water going through the spillway.We see what happens on a hillside that's been involved in a fire. Heavy rain + Exposed ground and roots = Mudslide. I don't see it been any different here.

Otherwise the retardant is ineffective. Not to mention, birds do fly at higher altitudes as well. |

Ok, it finally occurred to me to attempt to look at historical data instead of hysterical...
Looking at the electronic records is enlightening. Going back to the earliest online data (around 1986), it shows there have been only 4 instances where the peak inflow has been above 100k cfs. I understand that this can change, but based on past info, I would be comfortable right now knowing that only one time has it ever flowed so much that the current partially disabled spillway was unable to keep up with the inflow.
