Mississippi River Mile 63.5 to 65 AHP Saltwater Barrier Sill

Commencing on or about 9 October 2022 and continuing until further notice, the U.S. Government Contract Cutterhead Dredge
JS CHATRY will be working in the Mississippi River from approximate mile 63.5 to mile 65 Above Head of Passes (AHP).

The Dredge will be located in a borrow area on the Right Descending Bank (RDB) side of the channel. Dredged material will
be transported using floating and submerged pipelines and be discharged from a barge to construct an underwater sill across the width of the river at approximate mile 63.8 AHP. The Dredge will work 24 hours a day, 7 days a week, and can be
reached on VHF Marine Channels 67, 72, and 16. Any necessary navigation restrictions will be issued by the U.S. Coast Guard.

Mariners are urged to transit at their slowest safe speed to minimize wake and proceed with caution after passing arrangements
have been made.
