It seems spillway control had been inop since November. Once water overtops an earthen barrier, the collapse is usually pretty quick. There's lots of YTs showing dam collapses.
True, but the spillway section was not earthen dam, it was reinforced concrete. The earthen dam section was the road section leading up to the spillway
AFAIK. Maybe I'm misunderstanding the design; the dam was built in 1956 - are there drawings of the dam structure? Was this a concrete spillway on top of an earthen dam? That is certainly not unheard of, the recent Oroville dam debacle in California is certainly an example of this.
