Dredging Operations


Twin Lakes will begin dredging the federal entrance channel on Monday, November 13, 2017. Entrance dredging operations will continue through April 2018. All material will be disposed of on the beach or through the offshore pipeline. The disposal area is condensed due to the County of Santa Cruz Twin Lakes Beachfront Improvement project, which is currently underway.

The typical dredge schedule is Mondays - Thursdays, with maintenance performed on Fridays.

Learn why seasonal dredging of the Santa Cruz Harbor is necessary, how it is done, and its effect on the environment.

During dredging operations, pass Twin Lakes on the east side (Crow's Nest side) of the channel unless otherwise marked. Stay at least 50' from the dredge. Contact the crew for passing instructions on VHF channel 8. Know tide and weather conditions prior to transiting the entrance and what your vessel draws. The entrance sounding is corrected to mean lower low water.

NORTH HARBOR DREDGING - October 2017 - April 2018

North harbor dredging began on October 16, 2017, in the X-J channel area and culvert area using Twin Lakes, and will continue for the remainder of the season using Squirt, and the Port District's submersible Toyo pump. The dredging window ends on February 28, 2018, for material comprised of less than 80% sand, and continues through April 30, 2018, for material greater than 80% sand, in accordance with the Port District's permits.

Mariners are cautioned to be vigilant when transiting in the north harbor area as submerged pipeline hazards may exist. Please review the attached graphic which depicts the typical pipeline configuration depending on the location of the dredge.
