Community Update: Construction to Resume at Scotts Mills Dam

Trent-Severn Waterway National Historic Site

Parks Canada’s construction projects are considered part of the Agency’s critical services to the public. As such, work has continued on them over the past several weeks.

May 4, 2020 –Construction of the first two sluices and completion of the secant retaining wall on the eastern shoreline is set to resume as early as this week.

The Scotts Mills Dam at Lock 19 is centrally located and as such remains an important part of the Peterborough community by way of public space, flood mitigation, environmental protection and through navigation. As construction progresses, curiosity builds for what the finished dam will look like. Wonder no more, we have that covered.

The Scope

The Scotts Mills Dam at Lock 19 is in the process of being 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 once restored.

What’s next

  • Demolition and excavation are almost complete with construction of the pier, base slab, and stilling basin to follow.
  • Pile driving is projected to resume in June, and additional construction noise can be expected.
