About Hogs Back Dam and Fixed Bridge:

Construction of the first dam at Hogs Back began in the late 1820s and was plagued with many challenges. Throughout its construction, the dam was compromised by unexpected high waters and the winter frost impacting its foundation which resulted in its collapse on three separate occasions.

Colonel By’s team eventually installed timber cribwork and added a water waste weir to allow excess water to bypass the main dam during high flows. This dam was completed in 1830. Throughout the mid-to-late 1800s the dam sustained significant damage and underwent repairs. A reconstruction effort took place in the early 1890s.

The version of Hogs Back Dam in place today was completed in 1977 along with the fixed bridge. Hogs Back Dam is the currently second highest dam on the Rideau Canal system, following the dam located at Jones Falls.

The replacement of the Hogs Back Dam and Fixed Bridge is part of Parks Canada’s infrastructure program, a $3 billion dollar investment over 5 years that supports infrastructure work to heritage, visitor, waterway and highway assets located within national historic sites, national parks, and national marine conservation areas across Canada
