The emergency spillway of the Oroville Dam is expected to fail, according to the Department of Water Resources.
An immediate evacuation order has been issued for low levels of Oroville, a town of nearly 16,000 just north of Sacramento.

Officials say that operation of the auxiliary spillway has resulted in "severe erosion that could lead to a failure of the structure." Such a failure would result in an uncontrolled release of flood waters from Lake Oroville.
