When approaching the lock, wait for the proper signal; then enter at a reduced speed. Safety is the prime consideration when locking any type vessel through a lock. Lock operators must require all people on a deck outside handrails, all children under twelve years of age, the person catching and/or tending a line, and any other person the duty operator considers in danger of falling overboard to wear personal flotation devices (life jackets) when locking through each lock on the Tennessee Tombigbee Waterway.
All vessels must have a mooring line and must be properly secured to a mooring bit (not a fixed bit) prior to the beginning of lockage. Floating mooring bits have the potential to become stuck, either by debris or damage to the bit or recess tracks, causing the bit to not rise or fall with the water level. To prevent accidents involving stuck floating mooring bits, vessels are instructed to “loop” the mooring line around the floating mooring bit instead of actual tying off to the bit or boat cleat. Once the mooring line is looped around the floating mooring bit, a person either holds the line in his/her hand or loops around cleat on vessel in manner that line can be released from the bit or cleat quickly to avoid the vessel being pulled by a stuck mooring bit.
Wait for the lock operator's signal to leave the lock and travel at a reduced speed. For your own safety, vessel operators must obey all directions given by the lock operator. Restricted areas around the locks are indicated by buoy lines and signs. These areas are restricted for all activities including fishing.
