I think there were some speculation that the flow was reduced due to eroding the inlet channel. Not sure this is a big deal. DWR stated they turned the flow down so they could resume work at the bottom of the spillway clearing debris so the river level leading back to the powerhouse could be reduced. The inlet channel seems to slope up towards the gates BTW. https://youtu.be/XZO_744b_Gs https://www.youtube.com/watch?v=XZO_744b_Gs View Quote Thanks for posting that video, it makes the channel for the spillway make a little more sense. |

The massive chute is 178 feet wide, as wide as 15 lanes of freeway, and just 15 inches thick in the middle. I new it was big but 15 lanes wow. They really do dump as much water down that as goes over Niagara falls. |

Ever notice how these gloom and doom scenarios always have a common thread? There is always some core belief that the government is holding back some sort of information, and the author is the only one privy to the "real" information. If the conspiracy of government withholding information falls through, the whole theory of destruction is out the window. View Quote If a simple visual inspection, up close and personal, had been done of the spillway over the last 5 years, there would be no problem or conspiracies to talk about. This really has been comedy of errors. |

His assumption relies on every drop of water entering that dam all at once (impossible) rather than over time. The e-spillway, should it remain intact, will never see feet of water going over it. |

So with the rain the area is presently getting, what is the inflow looking like ?

View Quote Just a curiosity question about that photo: I wonder where the drive in point was for getting those trucks into the spillway? Did they make a temporary one for that operation and then fix or remove it later? |

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 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. To the best of my knowledge no mining equipment ever broke through ice at the Centralia mine. Winters here are relatively mild at +/- 400 feet above sea level. I've never seen a river here ice over in over 50 years here. There were several land slides of spoils through the years and a large walking dragline sunk in a soft spot once. The tub was tilted about 30 degrees from level. It walked free after undermining material and re-constructing a new pad under the opposite side of the sunken portion of the tub. Link to video? |

https://s28.postimg.org/d2ikvo1ct/IMAG0185.jpg Okay here's how it should work... It rains... Some flows out, if too much comes in it gets stored then released later. It does not, as already said above come in at the same time. It also depends on the intensity of the storm , so 9" of rain as a total over 30 minutes is very different to 9" of rain over 24 hrs.

Spillway Before/After (Slide to compare thing)
It's pretty clear that when they finally noticed cracks in the concrete a lot of their anti-cavtation water had already flowed under the ramp, eroding it bit by bit and was either non-checked or ignored ("Hey, we're in perma drought!"). The distance that ramp fell didn't get eroded in the past two months. Their Patches were somewhere between proper patches and road patches, they obviously didn't ensure the ramp was sitting on something solid. The ramp was originally poured on ripped away bedrock, so there should be NO open areas/spans beneath ramp, it was designed as a water road, not a bridge. Lastly, has anybody seen a link to the maintenance records they said would be made public several times now? And lastly, to the members here believing what the TV is telling them... They are releasing their numbers/data, they don't make it easy to get and manipulate (hence the spreadsheet), but they are releasing them. At their press conferences, however, they twist the hell out of those numbers and forecasts to make it seem nothing at all is wrong with the dam. |

View Quote Last year was the first time in 5 years that they ran water over the spillway. Than ran something like 8,000 cfs and it tore big holes in the spill way. Instead of thinking they needed to do a full inspection they just patched it, the way any state worker would. As you mentioned clearly their were voids under the spillway. They apparently never asked why or thought it was a concern until the ran water last Tuesday which destroyed the spillway. |
