The Trent Severn Canal names this lock: Lock 45, Port Severn Lock. It is the smallest lock on the canal in terms of the size of the lock chamber. The drop is 14 feet, lowering boats to the level of Georgian Bay and Lake Huron.
For Last Dance it was lock number 440, the 440th lock transited since the beginning of the Great Loop journeys, March 1, 2011. Locks have moved the boat to higher or lower water levels on the Mississippi River, Illinois River, Chicago River, Ohio River, Tennessee River, Cumberland River, Ottowa River, St. Lawrence Seaway, Tenn-Tom Waterway, Erie Canal, Champlain Canal, Chambly Canal, Rideau Canal, Trent Severn Canal, Dismal Swamp Canal, and Oswego Canal.
Above, Last Dance is tied to the wall with the blue line, indicating to the lockmaster that the crew wishes to lock through at their earliest convenience. When Lock 45 began operation at 9:00 am, Sunday, June 19, 2016, Last Dance was the first and only boat to be locked down.
