Otonabee Dam at Lock 23 Replacement

New mandates

By Johanne Laurin 11 January 2019

EBC is pleased to announce the awarding of a second project on the Trent-Severn Waterway in Ontario. This time, it’s about replacing the Otonabee Dam at Lock 23, located approximately 2.8 km south of the Douro Dam, in the City of Peterborough.

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 80-100 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. Lock 23 is part of a run of five 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 dam is part of the Trent-Severn Waterway National Historic Site. Since some dams in this section of canal are nearing the end of their life, Parks Canada Agency has initiated a program of repair.

Our Mississauga office will be responsible for the project. The preparatory work started in December 2018 and the project will continue until December 2020.
