Oroville is one of the highest dams in the nation. The earthen dams at 890 now 12 feet from overflow. Meanwhile, the chute hasn't cured yet making it impossible to let more than about 12,000 cubic feet per second out. The heavy rains and snow are likely to take the dam up to 900 feet. Each additional foot plut a huge additional amount of pressure on the earth around it.
There are reports that liquefaction might already be taking place due to the high pressure. IOW, the eating away of the ground under the dam that keeps it stable.
