History
Construction of the Big Chute lockstation
Constructed: 1917; 1923; 1978

In 1914 contracts were awarded to build locks to connect the Severn River to Georgian Bay with one of the locks being #44. Wartime shortages stalled the start of construction, but the first marine railway was built in 1917 and then replaced in 1923. The current marine railway was opened to the public in 1978 and has been instrumental in halting the spread of sea lamprey to inland lakes.
