Timiskaming Dam Replacement

The Timiskaming Dam Complex is located on the Ottawa River, approximately 65km northeast of North Bay Ontario, on the border between Quebec and Ontario.

This project included:

• The construction of a temporary downstream cofferdam
• Complete replacement of a 120m wide flow control dam on the Ottawa River
• Installation of a new dam approach road
• Demolition of the existing dam road deck and piers
• Commissioning of a new dam operational equipment system

Construction and demolition were done in phases to accommodate the numerous restrictions, fish spawning-in water work, spring freshet releases, high-pressure gas mains and permits.
