The agency that manages Oroville Dam says the facility’s rebuilt spillway is likely to be pressed into service for the first time as soon as next week. The Department of Water Resources announced Tuesday that Lake Oroville has risen close to the point where the agency will need to release water to maintain empty reservoir space for runoff from incoming storms and spring snowmelt. DWR said it will give the public between 24 and 72 hours advance notice of a release, which can be expected to cause relatively rapid rises on the Feather River downstream of the dam.
