The Alberta government says it has secured all the land it needs to make construction officially a go on a long-awaited reservoir needed to protect Calgary and surrounding communities from disastrous floods — like the one that killed five people and caused billions of dollars in damages in 2013. The $432-million Springbank off-stream reservoir will redirect water from the Elbow River into a dry reservoir should extreme flood events occur. With up to $168.5 million in federal funding, the reservoir will be built on about 1,497 hectares of land near the rural community of Springbank, which is west and upstream of Calgary.
