Flooding in Calgary

Flooding can occur at any time with little to no warning. May 15 to July 15 is when we receive 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.

For a history of the 2013 flood, see Calgary 2013 flood.
