8,4 km – 8,6 km

Up to Hogs Back, the Rideau Canal is an artificial waterway of excavated channels and a drowned swamp, Dows Lake. Hogs Back Lockstation marks the transition from excavated channel to the Rideau River. Access to the river was made possible by the damming of Hogs Back Falls. This resulted in the raising of the level of the river to create a slackwater section that boats entered after passing through the two locks. An earth embankment dam separates the locks and excavated channel from the natural river course and maintains the water level for navigation.
