The Oroville Dam Failure

I have heard that the emergency spillway is eroding through cutback. This will be an evolutionary erosive failure. It will take some time for the cut back. Hopefully the erosion will be stopped at bedrock, However, I fear that if the erosion of the emergency spillway, on the canted bedrock of the abutment communicates with the hydraulics of the principal spillway, this may result in a V notch failure. This would be the most serious type of failure.

That is what Pete Giddings on channel 2 in the Bay area is hinting when he says total rainfall in the Upper Oroville area.

Total Rain not snow fall.

Warm rain will melt snow packs.

Our north coast rivers are below flood stage but the ground is saturated and any more rain will run off into the rivers. A dam failure on the upper Mad River would flood a couple of small towns and the lower parts of the town just north of Benderville but we are safe except for a tsunami on our coast line. Our area had the Mother of all Floods in 1964...
