The Coast Guard published five waterway actions in the Federal Register on Sept. 17, 2026: two rules and three proposed rules. The day's output puts safety and local regulations in Florida and Ohio alongside a set of drawbridge schedule proposals for Connecticut rivers. One finalized rule establishes a safety zone in the Key West Main Ship Channel and Fleming Key Cut in Florida ^[1]. The other sets a special local regulation on the Maumee River in Toledo, Ohio ^[3]. Both are listed as rules, meaning they take effect as published. The three proposed rules would change drawbridge operation regulations on the Mystic River in Mystic, Conn. ^[2], the Niantic River between Waterford and Niantic, Conn. ^[4], and the Connecticut River in East Haddam, Conn. ^[5]. As proposals, they carry no effective date on the record.
