As the upgrade of Glenmore Dam draws to a close, NCEexplores how the Canadian structure has evolved to help reduce flood risk, while increasing its water supply capacity.

Canada’s Glenmore Reservoir has become an important landmark in the city of Calgary, providing clean water, flood mitigation and a recreational setting for locals. The 3.8km2 reservoir is formed by a concrete dam, which has been the focus of a C$81M (£46M) improvement project.

Approximately 320m long, Glenmore Dam is located on the Elbow River in south west Calgary. The structure was originally built in 1933 to supply drinking water and enable the city to cater for future population growth.

Increased water demand

More than 85 years after the dam’s construction, the city’s population has increased by almost 1,500% to over 1.2M, significantly increasing water demand. But as well as the need to future proof the water supply, Calgary has also had a series of significant floods – in 1996, 2005 and 2013.
