Update on the Napa River Dredging Project

The official kickoff of the Napa River dredging project is expected in mid-September.

According to a spokesman from the U.S. Army Corps of Engineers, the dredging scheme has been scheduled for mid-September and will last through November.

The dredging will remove around 300,000 cubic yards of sediment from a 13-mile stretch of the river, starting from the Third Street bridge in Napa – the upper limit of the navigable channel – south to Highway 37 in Vallejo.

Material removed during the project will be deposited at various sites, including lands off Imola Avenue and Milton Road.

The project, which will concentrate on shallow spots hazardous to watercraft, will be the federal agency’s first maintenance of the waterway since 1998.

The Napa River Channel is a shallow draft channel approximately 16 miles long, that is mainly used for light commercial and recreational navigation. The channel extends from the City of Vallejo, which is located on San Pablo Bay, northward to the City of Napa.
