Due to forecast storms in the Feather River basin, The Department of Water Resources (DWR) has taken steps to prepare for use of the main spillway. DWR anticipates use of the spillway for the first time since it has been reconstructed on .April 2.

“DWR has restored full functionality to the Oroville main spillway and is operating the reservoir to ensure public safety of those downstream,” said DWR State Water Project Deputy Director Joel Ledesma. “The Oroville main spillway was designed and constructed using 21st century engineering practices and under the oversight and guidance from state and federal regulators and independent experts.”

The information below reflects current reservoir level estimates. Forecasts can change quickly and may affect the estimates provided.

DWR may increase releases to the Feather River again later this week to between 40,000 and 60,000 cfs to prepare for forecasted inflows.

The main spillway and the emergency spillway are reconstructed and able to handle flows as needed to manage reservoir levels and provide flood protection for the surrounding communities. Public safety and flood protection are DWR’s top priority in operational decisions regarding Oroville reservoir.

Oro Dam Blvd. East will be open to pedestrian and vehicle traffic unless flows from the main spillway exceed 30,000 cfs. If spillway flows exceed 30,000 cfs, the road will be closed to ensure public safety. Credentialed media will be provided access past the roadblocks located at Glen Drive and Canyon Drive and can use turnouts along Oro Dam Blvd. East.

DWR has followed its standard process of notifying regulatory agencies, local maintaining agencies, local law enforcement and local elected officials regarding the anticipated use. The Department will continue to update the public, media and local partners through calls, emails, news releases and social media.
