Community Update: Dam Demolition to Begin

Trent-Severn Waterway National Historic Site

Cofferdam Installation –Dam at Lock 38

February 12, 2020 – As cofferdam completion draws to a close, workers are organising for the next phase of work. The work area has been dewatered and workers are preparing for the demolition of a large portion of the existing dam this week.

The Dam at Lock 38 was originally constructed in 1908 and has only undergone one minor rehabilitation since then. The full replacement of the Dam at Lock 38 will result in a renewed effective asset life of over 75 years, increase water management capabilities and have increased safety features for visitors and operators alike. Trent-Severn Waterway Community Update

What to expect

  • Construction noise that is consistent with regular construction activities, in addition to noise associated with demolition.
  • Demolition is expected to take about 3 weeks.

The Government of Canada has announced more than $615 million of work on infrastructure across the Trent-Severn Waterway and its reservoir lakes. As a part of this historic re-investment, major work is being done throughout the Talbot and Lake Simcoe community.
