Air Horn Signals: Vessels desiring passage through a lock shall notify the lock operator by three long and distinct blasts of a horn, whistle, or megaphone, when within a reasonable distance from the lock. When the lock is ready for entrance, the lockmaster shall reply with three long blasts of a horn, whistle or calls through a megaphone. When the lock is not ready for entrance, the lock operator shall reply by four or more short distinct blasts of a horn, whistle, or call through a megaphone (danger signal). Permission to leave the lock shall be indicated by the lock operator by one long blast.
Obey all the instructions of the lock personnel. Your total time in the lock will be approximately 45 minutes. The pool in the lock chamber will be raised or lowered 84 to 25 feet depending on which lock you are in on the Tenn-Tom. When the pool reaches the proper level, the gates will be opened for your departure. Please wait for the operator's signal to release your line and exit the lock at a slow NO WAKE speed.
