9.27.25 LWD Project Update: Mariner Notice

Please observe the below to keep everyone safe!!

There will be two dredges located on the west side of the channel this weekend as dredging continues on Saturday and restarts Monday morning. Please use extreme caution when entering and exiting Popponesset Bay. The outer channel exiting the bay is marked a No Wake Zone for the entire length of the channel. The sound side beach will be closed during construction activities while the bay side will remain open.

Dredging began this week with the dredge Sand Shifter on station dredging south. The second dredge Cod Fish II will be moved to the channel as early as Saturday (9/27) and will begin dredging on Monday (9/29). The area highlighted in below image dated 9/26/25 should be avoided as there will be submerged dredge pipe throughout this area. The pipe will be marked with yellow/orange poly balls. The submerged dredge pipe can be as high as 20” from the bottom. At this time, the east side of the channel will remain open during dredging operations and should be used when departing Popponesset Bay or entering the channel from the south. Please use VHF Ch. 18 to arrange for passage when the dredges are operating.

Please note the following: Dredging will take place Monday through Saturday from 0700 to 1700 when sea conditions allow. The dredges will remain on station in the channel and will have anchor lights at night as well as lighted decks.
