Update on Lake Oroville Operations
The Department of Water Resources (DWR) is alerting Butte County and Oroville residents of the impending closure of Oro Dam Blvd. E. between Rusty Dusty Road and Canyon Drive due to increased releases from the main spillway at Oroville Dam. Beginning at 9 a.m. on Friday, March 17, Oro Dam Blvd. E. will be closed to traffic prior to increasing spillway releases in stages from 25,000 cubic feet per second (cfs) to 35,000 cfs.
When releases from the main spillway exceed 30,000 cfs, water spray can reduce driver visibility on the roadway, requiring a closure for public safety. Motorists may still access Oroville Dam and the State Recreation Area via State Route 162 (Oro Quincy Highway) and Canyon Drive. Oro Dam Blvd. E. will remain closed to traffic until releases from the main spillway are reduced.
In addition, flows through the low-flow channel within the City of Oroville will begin increasing starting at 10 a.m. Friday. Flows in the low-flow channel will increase gradually from 13,000 cfs to 23,000 cfs by 4 p.m. Releases from Lake Oroville are being made in coordination with the U.S. Army Corps of Engineers and downstream water operators for flood control protection to downstream communities. DWR continues to closely monitor lake inflow levels and will adjust releases accordingly.
