Nearly 200,000 Residents Evacuated Near Oroville Dam
Over 180,000 people were given evacuation orders Sunday afternoon after a hole appeared in the auxiliary spillway of the Oroville Dam, sending water spilling over the top and raising the risk of major uncontrolled flooding.
"A hazardous situation is developing with the Oroville Dam auxiliary spillway," the Butte County Sheriff's Office said on its Facebook page. "Operation of the auxiliary spillway has (led) to severe erosion that could lead to a failure of the structure. Failure of the auxiliary spillway structure will result in an uncontrolled release of flood waters from Lake Oroville."
Evacuation orders have affected Butte, Yuba and Sutter counties. Cities with evacuation orders include Marysville, Hallwood, Ollivehurst, Plumas Lake, Live Oak, and Yuba City.
The Mercury News is already reporting that state and federal officials have been aware of the problem with the spillway for over a decade.
