NORTHERN CALIFORNIA – The California Department of Water Resources is closely monitoring Oroville reservoir levels and current forecasts.
Due to storms expected in the Feather River basin, DWR is taking steps to prepare for use of the main spillway potentially as early as the first week of April.
DWR is following its standard process of notifying regulatory agencies, local law enforcement and local elected officials for the anticipated use.
The department will continue to update the public, media and local partners through emails, news releases and social media.
To prepare for potential use of the spillway, DWR is removing construction equipment from the spillway chute. It will also remove a temporary road below the main spillway that has been utilized during construction. The road will be removed to minimize water quality impacts. Some turbidity is expected while the road is being removed.
Downstream monitoring is in place to track water quality. In addition, temporary cameras and lights have been situated alongside the spillway for observational purposes when water begins to flow down the chute.
Early Wednesday, the Oroville Reservoir was at 845 feet. The elevation on April 5 based on 10-day forecast is projected to be 850 feet.
Forecasts can change quickly and may affect the estimates provided.
Officials said the main spillway and the emergency spillway are reconstructed and able to handle flows as needed to manage lake levels and provide flood protection for the surrounding communities.
