There's been some major damage to the Oroville Dam Spillway. Photographic evidence and various news reports indicate the spillway suffered some sort of erosion damage, which may have caused chucks of concrete seen earlier today flying off the spillway path. This after dam operators increased the flows from the Lake because of excess water. The releases between 10 this morning and noon reportedly had to be stopped because of some damage.
Meanwhile, the CHP has CLOSED the road across the Oroville Dam with barricades in place.
