NAPA RIVER
OPERATIONS AND MAINTENANCE
PROJECT LOCATION AND DESCRIPTION
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. The Operations and Maintenance (O&M) schedule provides for a six-year cycle of maintenance dredging for the Channel to a depth of 15 feet Mean Lower Low Water (MLLW) from the Mare Island Strait Causeway to Asylum Slough (downstream portion) and 10 feet MLLW to the head of navigation at the Third Street Bridge in the City of Napa (upstream portion). The channel was last dredged in FY16 approximately 70,000 cyds of material was removed during the operation.

ISSUES AND OTHER INFORMATION
- The Napa County Flood Control and Water Conservation District is the NFS.
- The NFS has been actively pursuing additional Congressional funding.
- The project is on a 6-year cycle. However, in FY17, major winter storms caused a large amount of runoff silt to fill the channel with depths in some locations of -2 ft or less.
- The channel was last dredged in FY16 and approximately 70,000 cubic yards of material was removed.
- The NFS is also implementing a large flood-reduction project with the Sacramento District, USACE. Maintenance of the navigation channel in the Napa River will benefit the Napa River flood reduction project.
CONGRESSIONAL INTEREST
- 5th District, Rep. Mike Thompson
