Construction on Alberta's Springbank Off-Stream Reservoir (SR1) is finally complete.
The flood protection project is located west of Calgary in Rocky View County.
Construction began in 2022, nine years after the flood of 2013, which resulted in five deaths, the displacement of more than 80,000 Albertans and more than $5 billion in damages.
Extensive consultation was conducted with members of the public and First Nations, and after three years, it is now ready for operation.
In the event of a flood emergency, the dry reservoir will divert and store water from the Elbow River, releasing it once the emergency has passed.
SR1 has a storage capacity of 70.2 million cubic metres and a diversion channel spanning 4.7 kilometres.
"The Springbank Reservoir reflects the government's commitment to protecting Albertans, wildlife, and the diverse landscapes we all share," said Forestry and Parks Minister Todd Loewen in a media release. "This flood mitigation measure will ensure critical habitats are protected, meaning fish and wildlife populations in the region can continue to thrive, while also protecting the outdoor spaces Albertans hold dear."
The project’s total estimated cost was $849.4 million, including land purchases.
Its completion comes just in time for the 2025 flood season, which runs from May 15 to July 15, according to the City of Calgary.
