Engineers have been using 'patch and pray' techniques to repair Oroville Dam for YEARS as shocking pictures show the scale of the erosion caused by huge hole opened up in the spillway Engineers had been using 'patch and pray' techniques to repair California's crumbling Oroville Dam before it threatened to collapse last week and sent the region into a panic. Cracks in the main concrete spillway have been included in site reports since 2009 but crews have been using quick-fix concrete solutions to try to stop them from getting worse. Engineering experts described the effort as a 'patch and pray' approach on Wednesday as the emergency situation in Oroville persisted. 200,000 people were suddenly evacuated on Sunday when the California Department of Water Resources dramatically announced that an emergency spillway at the dam was an hour away from collapse. Since then, crews have been working round the clock to beef it back up by lining it with boulders and are racing against oncoming storms which may hamper their efforts. Residents nervously returned home as the evacuation order was downgraded to a warning on Tuesday but they have been told to be ready to flee again at a moment's notice if the volatile situation turns on its head again.

This vid shows more of the same patch and pray. They don't have enough time. It is a valiant effort from engineer 'Todd' and crew to keep dropping bags of rocks until it starts raining too hard for the helos. Only 8 percent of the hole is finished on the main spillway. He talks about the lakes that drain into Oroville Reservoir being full up already, not included in the rainfall filling of the lake. I checked the rad levels at NETC.com tonight. This last week looks pretty high for radiation so stay out of the rain if you can. Fallout from rain tends to drop at the foot of mountain ranges, on both sides, like at Oroville. I doubt anyone has a geiger on hand. Sure would be interesting to know a general count of CPM in the rain- :) |
