September 17, 2018- Community Update: Upcoming Dam Replacements

As a part of the historic investment program along the Trent-Severn Waterway, work began this fall to replace the Dam at Lock 23 Otonabee in the City of Peterborough.

The Dam at Lock 23 Otonabee is located in the very north of the City of Peterborough. Lock 23 is part of a run of 5 locks that take boaters from Lakefield to Peterborough along the Otonabee River. This site also has an intake for the hydro power generating facility, run by Peterborough Utilities, located downstream at Lock 22.

This major project will see the full replacement of the dam with a new structure. Not only will this work provide a new dam with an expected lifespan of more than 60 years, it will also reduce leakage and increase the safety of water management operators and the public.

The new dam will be built in phases to allow the continued flow of water as part of the Trent-Severn Waterways system of water management. The construction site itself will be accessed from both sides of the river with the bulk of construction in the first phase to take place from the Eastern shoreline.

Construction is expected to take more than two years.
