Scotts Mills Dam Replacement | Peterborough

The Scotts Mills Dam at Lock 19 will be fully replaced with a new dam that respects the historic look of the site and has a life expectancy of more than 80 years. The new dam will optimize hydraulic capacity, increase the safety of water management operations, and be constructed in a way that allows improved access for maintenance activities. In addition, the project will be the first step in creating a more public friendly lock site, with pedestrian access onto the dam itself restored.
