Have not been following this closely, but whoever drafted the "60-minute imminent failure" header should be punished.
From the link in the op's post. It was the state that said it would fail in the next 60 minutes.
The California Department of Water Resources issued a sudden evacuation order shortly before 5 p.m. Sunday for residents near the Oroville Dam in northern California, warning that the dam’s emergency spillway would fail in the next 60 minutes.
The Oroville Dam is the highest in the nation.
An emergency alert issued on Facebook stated:
EMERGENCY EVACUATION ORDER ISSUED: Officials are anticipating a failure of the Auxiliary Spillway at Oroville Dam within the next 60 minutes. Residents of Oroville should evacuate in a northward direction, toward Chico. Other cities should follow the orders of their local law enforcement
