Flooding in Calgary

Flooding can occur at any time with little to no warning. Historically, May 15 to July 15 is when we experience our largest rainfalls and are most likely to experience flooding. Understand, prepare and stay informed by knowing your flood ​risk and how to prepare for flood conditions.

The Flood Mitigation Measures Assessment and 2016 Flood Resiliency Analysis report, outlining recommendations for future flood mitigation, is being presented to Council on March 22, 2017. To see these reports please visit the meeting agenda.
