Quote HistoryQuoted:
Water seeping under through small fissures in the foundation material has very little energy in it due to the low head differential +/- 1 or 2 ft. Where as there's a lot of energy in the water going overtop of the weir +/- 20' of head. It's that energy that causes down stream scour And the water is still fairly high up on the weir. If flow through the rocks under the weir were happening you'd have water flowing downstream of the weir now. Scouring under the weir causing a collapse would seem to me to be the panic. Not sure an end run around the weir is a huge issue - unless it undercuts the weirs base and starts peeling the weir away from its base. |

Quote HistoryQuoted:
The Espillway should have never been built that way. It should have been solid concrete with a high spot on each side and the water only be allowed to spill over concrete. Allowing water to flow over one end of it was and is always going to end in a failure. Everyone had to know that. It was never supposed to get to this point. The emergency spillway is exactly that. Flood control not water storage. Avoid cat a tropic full damn failure. Thanks iPhone. It's a sacrificial lamb. The espillway that is. A cluster fuck of engineers screaming and somebody not listening. Pay now or pay much more later. That's what engineers do. |

What I'd like to see is something that confirms the base of the weir is at roughly the same design and elevation the full 1700 feet, or if it terrain follows. It''s not the same cross section all the way across. The two different cross sectionshave been posted multiple times. The weir near the parking lot does not go into the ground very far at all. |

If water cut a hole into the ground there, it continued to cut a tunnel until it resurfaced. Putting bags of rocks on the surface is like putting a bandaid on a sucking chest wound. It needs excavated and filled and compacted or pumped full of grout or wet concrete. Is that the entrance or is it the exit? I see the topo but that sinkhole they're filling doesn't seem like an imminent threat to the weir if it's the top of the feature. Could they be preparing to pour into a sinkhole behind the weir? |

Looking at the pics of the weir from the helo it does seem to be a crack along the base. Long dark blue crevice just a few feet out from the ripple concrete plates.
If it's working down to bedrock and then tunneling down slope it means that area is prone to slippage and it could all go into the river - which blocks the channel and backs up the main flume discharge even more until it tops out and then goes roaring down stream in it's own way. From the parking lot to the slope is more dangerous as it means it's pulled an end run under and around the rise in the ground they counted on to be substantive enough to stop the water. Now it's a VC tunnel under the Embassy and the next rainy day it could/would fail. Clocks ticking ( as if they don't know it. ) We see this a lot in SW MO because of all the underground lead and zinc mining - if it rains the tunnels collapse, if there is drought the tunnels dry out and collapse. We get some in the area almost every year. Cali went from rain to drought to heavy rain, it's stressing the ground structure and developing fissures. Open water sitting on it is going to work them even more. |

While you were off getting back to nature the other day,  the rest of us were watching water rolling down the weir face, and seemingly disapopearing beneath the ground. i want to see where it went.

We thought that was bs until a friend of mine in wildfire management with the forrest service confirmed it, guess you write your own checks when you have the biggest and the baddest. Negative. Maybe per day but not per hour. I've seen figures that the blackhawk is about $2200 per hour for fuel and maintenance Add in insurance, depreciation, profit, and pilot salary, and the figure is probably not getting up to 20k per hour, but it's going to be more than 20k a day. |

Quote HistoryQuoted:
With the potential head of water above those gates, they'really not going to be able to change the path of the spillway. The velocity is too great for any turns. Good point. What if we put in a high banked gradual turn like turn 4 at Daytona as it enters the super straight away?
I'd guess that leaves them either relocating the spillway (perhaps to the current e-spill location), or maybe some how coming into the gates at an angle so that ramp has no turns. Would also result in a lot of flow that isn't perfectly aligned with the structure. Darn this could be a really big darn deal. |

If water is standing on that parking lot while it does, that entire parking lot is going to be in the river.

I assume (maybe stupid of me to) that all the house boats on the far side of the damn are empty and anchored really good?
If the Espillway broke it will be moving a ton of surface water and I can see those boats going along for the ride, and those have to contain a good amout of fuel and or propane that can cause nice little booms when they get smashed up against something. I just haven't seen anything new about the boats and it made me think of those. |

We know there will be regular fill dirt under the road. We know the road extends west and ends in a cul de sac on the side of the ridge that could send water down the red marked area. I presume more water flowing down the existing part of the area already being torn up by the espillway wouldn't be such of a much all things considered. Yet there they are packing rocks in over there. My red marks surmise was speculation on what they may be worried about. |

Well, that is what the primary spillway was designed for. Too bad the let the dam thing fall apart. I had the espillway figured as a "fuse" that once blown, would have to be rebuilt. Point being, it saved the dam. Morons calling it an auxiliary spillway may as well be talking Democrat, where opposite speak is how the world works. |

The design makes it so that water can go around the espillway and if it does long enough it doesn't matter if the Emergency spillway is the proverbial immovable object. The result will be the same as it the walls all fell down. |

You can't be trusted so I fixed it for you. https://www.AR15.Com/media/mediaFiles/369185/map-of-bag-drop-146264.JPG There was an official aerial map posted several pages back showing the projected flow in the event of an e-spill failure and NagOrzo15-1 is right. They had it flowing from that corner of the parking lot taking that exact path. |

Hey look, bedrock. Can we put the whole "it's not built on bedrock, it's built on fill" thing to rest now. |

This deserves a re-post. Credit to slankford for digging it up. Notice the espillway is *not* anchored to bedrock. https://www.AR15.Com/media/mediaFiles/369185/Oroville-erosion-146155.JPG |

I assume (maybe stupid of me to) that all the house boats on the far side of the damn are empty and anchored really good? If the Espillway broke it will be moving a ton of surface water and I can see those boats going along for the ride, and those have to contain a good amout of fuel and or propane that can cause nice little booms when they get smashed up against something. I just haven't seen anything new about the boats and it made me think of those. There wouldn't be any boom. That shit only happens in the same place silenced rifles go phut phut phut on full auto. To make a boom with gas you need lots of vapors and a high intensity ignition point like a spark from a battery. Those boats will just leak a little fuel that nobody will every notice. |

No, they should've spent the money to properly fix the main spillway, and they shouldn't have tried keeping the dam at 99.87% capacity all the time using the spillway gates way too frequently. Compare this dam to Fort Peck in MT. The CoE only needs to use the Fort Peck spillway once a decade because they continue to operate Fort Peck as flood control and power production, instead of water conservation. Plus, the CoE properly maintains and repairs the Fort Peck spillway for the infrequent times they need it. Quote HistoryQuoted:

This is a good photo showing how close the erosion is to the Espillway https://pbs.twimg.com/media/C4lZm_qUoAAt5ON.jpg Ed That erosion is somewhat alarming |

Actually one of the guys posted a video of governor Reagan dedicating it, he said watershed....I doubt they ever planned for it to be filled to near capacity year round though... |

Quote HistoryQuoted:
Again, not being an apologist for the idiots in charge of this fiasco, but you're incorrect saying the dam was not built for water storage and only for flood control. The dam was built for water supply, hydroelectricity generation and flood control. In 1951, California State Engineer A.D. Edmonston proposed the Feather River Project, the direct predecessor to the SWP, which included a major dam on the Feather River at Oroville, and aqueducts and pumping plants to transfer stored water to destinations in central and southern California Built by the California Department of Water Resources (DWR), Oroville Dam is one of the key features of the California State Water Project (SWP), one of two major projects passed that set up California's statewide water system. The California State Water Project, commonly known as the SWP, is a state water management project in the U.S. state of California under the supervision of the California Department of Water Resources. The SWP is one of the largest state-owned water and power utilities in the world, providing drinking water for more than 23 million people and generating an average of 6500 GWh of hydroelectricity annually. Since its completion in 1968, the Oroville Dam has allocated the flow of the Feather River from the Sacramento-San Joaquin Delta into the State Water Project's California Aqueduct, which provides a major supply of water for irrigation in the San Joaquin Valley as well as municipal and industrial water supplies to coastal Southern California. California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California. True, water supply is part of it. If you read the source I linked on page 131-ish, it was approved for 2.4M Acre Feet per year. They've been running it 50% above that, and therefore lost FERC licensing, since the dam was not designed to be run at that capacity. They planned on having it near double that, at 4.1M AF/year by 2010 "with some modifications". The paper is from 1991, before any of the crap started. All CA Dams have been keeping thier "low pool" higher and higher, making these floods a certainty. It's Engineering a disaster and then blaming the original Design team for it not handling 150% stress for the last 20% of the life of the dam. NOW, add in lack of maintenance. Lack of inspections to decide if maintenance is needed, actually. CA is going to flood, maybe not this week, maybe not this year, but these reservoirs are not going to hold if they keep trying to push the limits year after year after year. Then try to declare "EMERGENCY!" when their fuckup goes sideways. The dam failures I've seen since y2k are all due to the increased water storage due to "Global Warming going to be drought forever" hype, not just in CA. |

That looks like bedrock to you? Sure looks like loose rocky dirt to me. The one picture shows solid granite like at the bottom of the main spillway, but I still think sections are on that decayed broken up bedrock we see just down slope |

Holy shit!
I have a relative there hauling rock to the dam. I did not know where he was living until he started putting pictures up on his facebook. One pic he is posting from his truck with a caption "Heading to Marysville for a load of rock then to the dam in orriville and hope it don't disappear".

Neither balls of steel -nor stupid... Just doing their job...  I highly doubt thier job requires them to climb down into an unstable washout with potential for cave in without safety considerations. Hell, even the guys that Rand my well line would set foot in the 12' deep trench without safety zones and harnesses. 34 workers died building the dam. Hopefully she doesn't take more lives.
