Been following this thread from day one.
I live at the confluence of the Ohio and Mississippi, after looking at all the inflow/outflow numbers I did some checking of the Mississippi. Just south of me at Memphis......Holy Shit ZOMGWTFBBQ its been flowing about 1.4 Million cfs for the last week!

I've been following since day one so forgive me as all the pics and pages seem to just blend together in my mind. Has it been posted here or released what they are planning on doing exactly for the rebuild? Like a chart or list of what they are doing where? Thanks One of the best threads on here imho

I was reading a magazine at the barber shop the other day. It had an aerial photo of the dam. Was that yours?

I suppose they will be using the power house to maintain outflow.
Is 8000 CFS, IIRC. I've also been thinking about all the snow in the mountains... Hope they have it calculated... |

Looks like they're building access ramps onto the lower part of the spillway. Although why they're shoving dirt into it the hole, there in the middle on the left side, doesn't make a lot of sense.

The professor seemed a bit biased toward "decomissioning" in the interview, but he was right about DWR having no concept of "safe" or "risk". Reporter was wrong in that it took 3 years to build just the spillway originally. I can see how it might take 2 seasons now, but 3 full years? With no enviro regs causing delays, what could make it take that long? Though the ongoing lack of a batch plant tells me quite a bit straight off. These things are bigger than you are thinking. |

I have been wondering about decommission this dam. Without full use of both of the original river diversion tunnels, could they drain the reservoir quickly enough with water flow through the current penstock tunnels into the power plant and river diversion valve before the next rain season?

It's to prevent those flow levels from getting down stream and flooding everyone down there. If they had maintained the spillway such that it didn't get a hole in it... then they wouldn't have had to shut it down while they checked it out... and could have been using it to flow out reasonable amounts of water that down stream could handle and it would absorb the flood flows like it was designed to. But because they had to shut it down water built up higher than it should have... add to that the concern about running the spillway at higher flow rates due to increased erosion and the situation got out of hand. Point is... the Dam is a good thing... They just have to run it correctly as flood control and maintain it properly. |

Quote HistoryQuoted:
I get all of that. But everything has a lifespan, right? That guy in video above is talking about how the head gate structure is cracking. Replacing that might mean having to keep the reservoir at significantly lower level and relying on the power plant and river valve to maintain it there. I am just curious that if the dam became somehow compromised that it needed to be basically shut down for major repair or replacement, could it? Even with the energy dispersion ring properly replaced to allow safe use of the river valve, could they flow enough water out of the reservoir to empty it? How many cfs would that flow? They would need a way to get about 200,000 cfs out of the lake to safely shut everything down for major repairs. I don't believe they can do that with the power plant + river valve... and would need to add some other method of getting water out of the lake. |

Per California Department of Water Resources beginning as soon as Wednesday, May 24th, there will be aggressive
blasting operations at the Oroville Spillway, possibly on a daily basis.Exact times are not known, but do not be surprised if you hear explosions. As part of the recovery process, FERC is requiring that DWR install a siren at the construction site during the term of the construction. The purpose of the siren is to notify construction workers if they need to evacuate the construction site (i.e., for blasting), as well as notifying people adjacent to the site (i.e., hikers, fishermen, neighbors etc.) that they need to be aware something will be happening at the construction site. The siren is not for community evacuation purposes. |
