Dear Harbor User:

The 2017-18 dredging season is just around the corner!


Three areas of the north harbor will be dredged commencing October 2, 2017. To maximize production and efficiently return the shoaled areas at the turning basin, X-J channel and culvert area, and I-Dock area to design depths, crews will utilize the 16″ hydraulic dredge Twin Lakes for a portion of the work. Several dock fingers have been temporarily removed from a section of J-dock to facilitate the process. Crews will utilize the District’s smaller, 8″ dredge, Squirt, to perform the remainder of the work, once Twin Lakes is moved to the south harbor for entrance dredging (anticipated to start early-November).

A 10″ diameter plastic pipeline may be on and just under the surface of the water at times in the north harbor. It is black and difficult to see, and can create an obstruction to navigation. The pipeline may surface and sink in the areas generally depicted on the attached maps. Mariners should be observant of the pipeline and equipment hazards in the area and navigate slowly and cautiously. Access may be restricted at times.

The attached maps depict three areas in the north harbor where dredging will be performed, and the anticipated pipeline configuration.

Vessels displaced during dredging operations will be returned to their slips when dredging operations are complete. Boat owners whose vessels are in temporary berthing assignments will be informed of changes to the schedule.

If your vessel is in an area blocked by dredging equipment, and you need to use your vessel, please contact the harbor office for a temporary berthing assignment.


Entrance dredging is anticipated to start in early-November 2017, and continue through April 2018. The typical dredge schedule is Mondays-Thursdays, with maintenance being performed on Fridays.

Entrance soundings will be updated frequently and posted on the harbor’s website.

If you have any questions about entrance channel conditions or to report a hazard to navigation, please contact the Harbormaster’s office via VHF radio on channel 9 or 16, or via telephone at (831) 475-6161. For after-hours emergencies, please call 911. The dredge crew may be contacted on VHF channel 8 for passing instructions.
