this one from Yesterday seems like it was taken after they reduced flow significantly. Can see some of what's left of the main spillway. http://i.imgur.com/URQKnIY.jpg I'm surprised there's anything left of that lower portion. There must be a wall of stout bedrock (the only one in the area) it's built on. Ed |

Ed and a goldbug just knows...tons of yellow washed out and continues to wash out of those hills...just waitin to be picked up...and its bound to hit $2000/Oz this summer.... Unfortunately dredging in California is banned and has been for many years maybe 10 now. I have a 4 inch dredge on the side of my house and have ran 5 and 6 inch dredges in my life. My grandfather used to manufacture 8-10 inch triple sluice dredges back in the 60's and 70's. It's pretty tough to break even on costs if you can't move alot of material. Sure a guy can get lucky with a metal detector but most of the gold in Cali that a person can recover is placer gold, which is usually under water and is also small in actual size. Most would call it flake gold and is less then a pennyweight usually. You can get larger and I have picked 1 ounce nuggets myself a few times but that doesn't happen anymore with the current regs. |

I have removed many ounces of mercury from the bottom of rivers that escaped from sluices built in the original gold rush. Many times after moving feet of overburden to get down to bedrock you will recover gold flake , some nuggets if lucky and an amalgam of mercury and gold. You can separate the gold from the mercury thus gaining gold and removing mercury from the ecosystem. |

Useless dam trivia . . .
The coal mine (out of operation since 2006) I mentioned on pg. 204 has an accompanying steam generation plant next door. They burn rail delivered Powder River basin coal now. The steam plant operators own an earth fill dam several miles away on the Skookumchuck River to assure a year-round water supply. When I was doing some maintenance work at the fish ladder collection operation, I spoke to a surveyor doing a semi-annual dam inspection. His company has performed the inspections since it was built. I asked if the dam had moved at all since it was built. He claimed that it had "settled" about a foot down river from its original setting I then asked if the dam moves at all between the highest and lowest retention levels. He said it moves up river a couple inches when totally full compared to it's lowest level. I called bullshit saying "Yeah, that's a good one" thinking instinctively that pressure surely pushes a dam down river. He was serious. He explained that when full the maximum pressure behind the arc-shaped dam causes the center of the arc to "shift" up river slightly. Go figure. Anyway, I hope the CA factions responsible for the Oroville dam build a proper concrete spillway for the emergency outlet along with other needed repairs. I assume they will but who knows. |

Quote HistoryQuoted:
Good picture...looks as thought the hole in the main spillway is acting like a dam and directing water back towards the dam's toe.. Maybe they'd be better off blowing the rest of the main spillway right on outta there allowing the water to go on a straight line into the river in a spot where it won't erode back towards the dam...? with the flows seen already the chance that erosion will make a 90 deg left turn, erode another quarter mile of rock and dirt, then make another left turn to direct flow towards the dam is somewhat nil. |

Two questions:
1. So, it sounds like they have it safely under control (relatively speaking), at least for now? 2. Is there a way to calculate runoff from the snow pack when it starts warming up? (I'd think #2 would be an educated guess based on historical data, but I don't know) |

The whole thing, pedestals sunk in the rock and isolated with rubber. Would not take months to weld at all. Think ship construction with a bigger budget. The gap you are speaking of would have to be addressed either way. |

(I'd think #2 would be an educated guess based on historical data, but I don't know) As for 1. they're pretty close to lake level 850... So it would take a couple days for heavy sustained rain and or warm up to increased flows into the lake and raise it again. Assuming they open the gates back up to 100k cfs. Currently it's at 55k but they may be raising it to 60k in the next little bit. I don't know what they're plans are... we could even see them open up the gates further to 150k cfs or more... depends how bad the rains and warm up are and how desperate they are to avoid over-topping again or how confident they are of their juryrigged repairs. |

To get to the mercury you have to get down deep sometimes through 10-20 feet of overburden. Mercury is like gold in that it will drop through sediment layers as the river is churning and get into the deepest cracks and holes, right were gold likes to go. The theory with dredging stirring up the mercury was a scare tactic for the uninformed. Mercury will stay in the sluice of a dredge just like gold if it is sucked from the bottom. |

Yes I have a few I could go to right now and pan for gold. Panning or even sluicing for gold is just scratching the surface in terms of gold mining placer deposits. He is getting sand size and smaller flake gold that can be carried by storm surge rivers, even the larger gold flakes will migrate towards the center of the river channel. That's why dredging is so good. you are working areas that may not have been touched in decades or more and the wash out of upstream tertiary gravels have deposited gold back into those spots. Your buddy is pulling maybe a few pennyweights to maybe 10 if very lucky, I have seen 20 ounces come from one crack that got better going from the edge of the stream towards the center with 7 of those 20 ounces coming from one pocket in the deepest part of the crack. |

He would fill up a couple of the glass "crack" bottles every few months. When the water was low (either from dam release or near the end of summer) he would wade out as far as he could and look for hidey holes and bring the dirt back in plastic 5 gallon buckets and pan it. |

Any power line monkey's here? By watching that video , it appeared that what PG&E did was fly a pair of lineman to 3-4 of the towers closest to the main spillway on both sides and un - clipped the conductors from the insulators and installed stringing rollers and laid the conductor in it . The reason for that was to cut the wire down from both sides from a location where they could slack the tension off and let it down to the ground . The guy riding the chair from the helo had to cut the wire after it was slacked off from i'm guessing the tower closest to the main spillway , so they could roll it up from both directions . Lot of assumptions in my post i know , but since I'm a power line monkey thats my best guess ! Hope that helps |
