Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed quote, Just heard on kfbk radio (local). The new spillway has 7 feet minimum concrete up to 100 feet thick in areas where the bedrock was eroded... They only used concrete on the top, all the build up and all the emergency spill area is rolled fly ash paste. Rolled fly ash has a history of not being stable or able to stand strong water flow, a history of failures. The fly ash work was meant to be replaced over the next several years. Also, looks like there is a green spot on both sides of the dam, maybe all the way across now? |

It rained lots, so everything is green. Wait till the summer and if there's a green spot, you know there's water feeding that grass. |

Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed the biggest issue i can see is that they haven't given Quoting: Kung Fu Lover this this thing enough time to Cure, before running it at full throttle. Exactly. 30 days per inch of concrete. Any additive to accelerate curing weakens the concrete. So it's either still wet or cured but at expense of strength of concrete. |

Depends how far they had to haul it also,can't let concrete heat up,lot of variables. But as much canned fruit as you can afford. |

It's called the Miner's Ranch fault. It was discovered long after the dam was built by Beale Air Force pilots. If you dont have anything else to do, here's the study from 2010 by South Feather River Water and Power. Oroville gets their drinking water from Miner's Ranch Reservoir aka Saddle Dam. The fault is capable of a 6.5 earthquake. [link to southfeather.com] |

They knew about the faults where they wanted to pile up all that mine dump waste to get rid of it instead of reclaiming it. The papers of the day detail how the officials hid the earthquake data. A little research still brings it up. |

They built a concrete plant right on the hillside and made the concrete on site. Also it was over 100 degrees for most of the summer when they were working on the spillways, don't know if that makes any difference. But Oroville Dam is very remote, they had to build a concrete plant and make the concrete right there, it wasn't trucked in. |
