Special Notice: Hurricane Season

Mariners are advised that the Hurricane Season extends from 1 June 2023 to 30 November 2023.

Locks and Navigation Structures operated by the U.S. Army Corps of Engineers will attempt to pass navigation until such time that water levels and wind conditions render operations unsafe. The structures are then closed in accordance with Hurricane procedures.

Mariners will be given as much notice as possible when structures are to be closed. However, these structures may be closed on short notice well in advance of the actual storm. Mariners are advised to seek safe harbor as soon as possible.
