Looks like they are down there clearing the river. http://ww4.hdnux.com/photos/57/11/57/12360651/7/1024x1024.jpg Good. I've been wondering if it wasn't a mistake investing so much effort into shoring up the E-spill rather than dredging the river and getting the turbines running again to contribute a steady flow. I figured they knew they couldn't get that done before the next crisis but it's a good sign they're working on it. |

If they lose the dam it is several orders of magnitude worse than losing the Espill. The dam would scour the Feather basin bare and the wall of water would flood Sacramento. Does anyone really know how much water escapes if the E spillway breaches? To my untrained eye it seems plausible that the main spillway gates would be in great jeopardy. At what level will the bedrock hold? Can any section of the weir hold if there is a break? |

I don't know, but I've read that the dam proper is some 20' taller than the e-weir. The dam itself will never be overtopped. Given that the dam proper and the spillway gatehouse share a road on top and the gatehouse and dam are the same height, the picture bellow should illustrate the fact that the e-weir is somewhat lower. https://upload.wikimedia.org/wikipedia/commons/c/c5/Oroville_dam.jpg |

There is 21' from the top of the weir to the top of the dam. So that weir is something like 60' high at that point. There is concrete weir structure all the way to the far side of the parking lot. It's not as substantial as the weir section shown here. Somewhere out there there is a photograph that clearly shows it, I just can't seem to find it. The drawings of the dam showed it and showed the 2 different sections. It does not show how it is anchored or even if it is anchored to the rock.

Not having any luck on finding the original borings so far. For now here's a photo of the dam near the end of construction in 1967: You can clearly see the emergency spillway to the left of the main spillway and flume. A review of design manuals from that era indicates the structures i.e.: emergency spillway weir, main spillway, and flume may be supported on rock anchors. In addition it would not have been uncommon to pressure grout the rock to create a curtain wall below the upper control structures. https://www.AR15.Com/media/mediaFiles/11755/IMG-0510-146572.png FWIW: I owned a geotechnical construction company for 22 years. We did rock anchors and grouting for a living. Now I teach people how to do it.  The end of the weir with a footing, is the parking lot. The red dots bracket where the "curb" wall is alongside the parking lot. Note the lack of footing there. It doesn't look like they dug down very far to put that thing in. No way should they have been fooling around with the emergency spillway, and no way should it be used again.  Attached File |

I found a report that says the river valve outlet was partially repaired in 2014, and tested in 2014 - 2015 up to half capacity. Since the river valve uses the same tunnels as the plant, they can not open it without further flooding to the plant due to the debri at the end of the spillway backing up the water. Just ran across this for a diagram of power plant tunnels to give a visual of the setup. <a href="https://www.AR15.Com/media/mediaFiles/106468/Scan-Pic0014-1487036675831-8508251-ver1-146524.JPG" target="_blank">https://www.AR15.Com/media/mediaFiles/106468/Scan-Pic0014-1487036675831-8508251-ver1-146524.JPG</a> here's a larger pic with the story behind it <p style="text-align:left"></p> <a href="http://www.abc10.com/news/local/river-valve-damaged-in-2009-could-have-been-fourth-way-to-release-excess-water/408086236?utm_source=dlvr.it&utm_medium=twitter" target="_blank"> River valve damaged in 2009 could have been fourth way to release excess water</a> <a href="https://pbs.twimg.com/media/C4l3-E8VMAApR-b.jpg" target="_blank"><a href="https://pbs.twimg.com/media/C4l3-E8VMAApR-b.jpg" target="_blank">https://pbs.twimg.com/media/C4l3-E8VMAApR-b.jpg</a></a> According to this, it was repaired in 2014: http://www.nwhydro.org/wp-content/uploads/events_committees/Docs/2015_Annual_Conference_Presentations/04-Tuesday/4-Anderson.pdf |

It was always a water storage dam from its inception along with hydroelectric generation and flood control. Where did you get the idea it was only built for flood control? They haven't run the net flow negative this year, even though they were aware of double snowpack. Roughly, the 65% to 70% mark is where pre-melt conditions should be (top 150'). They've been pushing it at 80% before considering opening the spillway, regulating the top 50 feet. That is why they are treating it as storage instead of flood control. |

Not sure what you're seeing, but I doubt it. There's a shrub on the right side that can give an illusion of a discontinuity in the weir surface. There's also the fence to the left as you're looking at it. Question for the erosion experts: I somehow think that fence is a relatively new addition to the dam, maybe post 911. I could be wrong. But wouldn't that fence post create turbulence that the shape of the weir is basically designed to guard against? |

The amount of water that would pour through the breach would cut deep into any fractured rock and OP has heard there's seven big fractures under the weir. Probably 100' drop in the reservoir level, assuming there's solid bedrock somewhere underneath it. |

If that espill weir lets go not only will there be extreme flooding in Oroville and the surrounding area, but that weir and everything below it is going to clog up the river. Then what? Dumb fucks should have kept the main spill maxed from the beginning, just like the former DWR guy said early on. Fuck, this next storm will not be kind. Couple that with the snow pack melt and the next month or two will be interesting. The residents of Oroville won't be moving back in anytime soon. |

The e-spillway was untested. Now it is tested and the issues can now be resolved. I fully believe the water over the e-spillway was intentional, for this exact purpose. That is why they kept the spillway output so low to begin with. Once they thought there was a problem they bumped up the spillway output and 4 hours later the water stopped flowing over the e-spillway. I don't think so. They bumped up the flow from the main spillway because of the threat of complete failure of the espillway, not because the testing was complete. They were trying to save the main spillway when they were reducing flow over it. The upside was that they discovered that the main spillway suffered less damage at the higher flow rate. |

Just started watching, but this looks like they're working in earnest in the main e-spill area: https://www.youtube.com/watch?v=ux9MSHoVL2g I don't get what you're saying. Moved the soil from where? |

they will have no control of water going over the Espill and they know it, the input can easily outpace the spillway Quote HistoryQuoted:

Quoted:
earthen dams will fail from over topping because you create an erosion path that accelerates as it erodes. If the weir were to let loose - that would be unlikely to happen because you have primarily bedrock below it. You'd have a huge outpouring of water to the level of failure (which would be really bad downstream) but if the rock under the weir is reasonably solid it would stop at that point. If the ground between the primary spillway and the end of the parking lot is fill, rather than natural rock, then it would carve out a path and keep draining the reservoir until it did hit rock. The few drawings that have cropped up seem to indicate the bottom of the weir is to be on rock. The geologists / rock guys here will have to comment on the ability of the fractured surface rock shown to erode slowly enough to prevent catastrophic failure of the rock itself. They know that and that is why they are not going to let any more water go over that spillway. None. Not a drop. Watch and see. They will open the gates wide-open and lat the chips fall where they may before throttling that flow back again. If there is a 170,000 cubic feet per second surplus, that surplus would run over the e-weir until it either erodes the e-weir structure away, and/or displaces the entire weir/spillway gatehouse structure. That would open up that entire end of the dam complex. With a hole that big, water may back up to major levels on the main dam structure...but I'm still not buying that it would spill over the top of the main dam. The surplus, even at 330,000 cubic feet per second inflow, is only roughly twice the capacity of the main spillway. |

Quote HistoryQuoted:
They haven't run the net flow negative this year, even though they were aware of double snowpack. Roughly, the 65% to 70% mark is where pre-melt conditions should be (top 150'). They've been pushing it at 80% before considering opening the spillway, regulating the top 50 feet. That is why they are treating it as storage instead of flood control. They can only use the spillway once the lake is up to the bottom of the gates, there seems to be some question about the elevation but it's definitely between 811' and 850' The spillway failed more or less the first time they loaded it hard in the last several years, if I've read the charts right the lake never got high enough to put any significant flow through the spillway during the drought. It's all on their half-assed spillway repair that seems to have missed that there was a void forming under the cracks they just patched over. The had a perfect opportunity to repair that during the drought and failed to do so. |

Quote HistoryQuoted:
With ~98k CCFS outflow, its dropping at about 3.85 feet per 12hrs. Looks like they only have 36hrs before the next big storm. That's not going to be good. As long as they get less than 98k in they should be fine... As long as nothing breaks, or it doesn't cause downstream to over top, or... or... |

Ok where is that going?I'm wondering if it's Swiss cheese underneath which may have contributed to the dramatic concrete failure in the spillway a few days back. |
