Yep, the emergency spillway is uncontrolled and will release a torrent of water onto the hillside with trees and powerlines.Pretty scary stuff. Saw on the news tonight that they most likely are going to let it flow and deal with the damage after the rainy season. This is assuming that the 2 hr test they ran today at 4 pm went ok, guess the next decision is going to be made tomorrow A.M. The Dam does have an emergency spillway in case it is needed; it however, is not controlled by gates and could cause some flooding if used.
It was caused by a defective spillway and a high release of 60,000 cfs. That is a high release but the officials thought it was well within design constraints of the spillway.Is damage caused by old age or releasing water? Neglect?
Obviously something was defective; one reporter has commented about not seeing any rebar in the broken concrete of the structure (might just be a reinforcing mesh too small to see at a distance).It was caused by a defective spillway and a high release of 60,000 cfs.

It's gonna fill this weekend . Inflow is too great.A buddy tells me it's now 28 feet from the top. When it gets to 25, they'll evacuate Oroville.
