The Government of Alberta has approved a new flood mitigation project for Canmore that will help ensure public safety and lower the risk of flood damage, like that experienced in 2013.

In addition to homes and businesses, the Cougar Creek debris flood retention structure will protect critical infrastructure, including Highways 1 and 1A, the Canadian Pacific Railway main line, a school, and the RCMP detachment. Electric transmission lines and a high-pressure natural gas pipeline will also be protected.

“The Cougar Creek Dam will help mitigate the public safety risks posed by debris floods by providing a reliable level of protection for homes, businesses and critical infrastructure in Canmore,” said Jason Nixon, Minister of Environment and Parks.

All three levels of government are funding the $48.8-million project, including $30.3 million from the province. Provincial funding has been fully allocated for this project and the Town of Canmore is responsible for ongoing maintenance and operating costs, so there are no implications for Budget 2020.

“The Town of Canmore is excited to receive the final approval for the construction of the debris retention structure on Cougar Creek,” said John Borrowman, mayor of the Town of Canmore. “This structure is key to our long-term mitigation, and will protect thousands of Canmore residents during a flood event while safeguarding critical infrastructure vital to our community. We have been developing this major project in partnership with the province, and thank both the federal and provincial governments for committing 90 per cent of the funding for this important project.”

The Natural Resources Conservation Board (NRCB) approval includes conditions to ensure environmental impacts are minimized, commitments made to Treaty 7 First Nations are honoured, and plans for health and safety and emergency management are completed to the satisfaction of Environment and Parks.

The debris flood retention structure will be located on Cougar Creek, approximately two kilometres northeast of the Trans-Canada Highway. The dam will be nearly 33 metres high and capable of holding back up to 760,000 cubic metres of water and mountain debris. During a flood event, water and mountain debris will be temporarily held behind the dam, with water released back down Cougar Creek in a controlled manner.

Construction is expected to begin in summer 2020, with the project estimated to be operational by 2022.
