I wonder how much crap from the spillway is going to end up in the diversion pool.
More OT for the bucket operators.

I'm curious to see this too. Seems like since they're spilling at a way lower rate than their previous maximums there shouldn't be too much new erosion, but from the couple of videos Chokey has just posted, looks like that water coming down into the diversion pool is awfully brown and dirty looking. At a minimum the material they didn't get shoveled out yet will probably get re-distributed across the river channel and will need to be cleared out again, whether or not it builds up enough to raise the pool level and block outflows from the power station is the question for me.

Quote HistoryThese are from much earlier during the initial event, yes? Didn't think that the spillway was still in a contiguous piece?
ETA: Nevermind, I see now that it is water that has come back up and is going down the lower portion after the drop off from the top. |

I'm guessing they are spoilers or turbulence creators, or similar, to disrupt the semi laminar water flow, to relieve pressure on the rough edge of the spillway there, the same way as those huge 'teeth' on the bottom of the lower spillway were breaking up the smooth flow of the water before it dropped into the river. There is a particular name for these things which I cannot recall right now. But looks VERY intentional. |

Mounting points for those flow modifiers. I'm guessing aerated water is not as likely to curl underneath the lip of the spillway, preventing further upstream erosion underneath the spillway was the reason for installing them. |

https://www.youtube.com/watch?v=EA-O485hpgU Helicopter footage of gates open and at full flow. They left equipment on the far side of the emergency spillway just in case, I guess, or they plan on using it again. Power plant is shut down completely, only flow out is from spillway, where they want to get the level back to 840 ft, then probably repeat what they did with dredging and hope they can make the rest of the spring melt with the 60 ft of storage + power plant running? |

Notice how they were quick to point out that they did follow all procedures and are now evaluating the adequacy of those procedures. Will be interesting to see how the 70 year old engineering holds up, and determine if it was the design or operating and maintenance faults that led to the failures.

It's a testament to the original engineers and builders it has held up as well as it has. I don't think they ever intended for it to last forever with no maintenance. |
