Flooding in Calgary: Flood Preparedness

Flooding can happen at any time in Calgary. The period between May 15 and July 15 is when we are most likely to experience flooding since historically this is when we receive our largest rainfalls.

The City of Calgary’s priority when planning for and responding to flooding is to protect its citizens, critical infrastructure, civic property, the environment and the economy.

The City strives to maintain all critical business functions and services to Calgarians during any emergency or disaster including flooding.

The City does not typically protect individual private properties from flood risk. Property owners remain responsible for protecting their property.

Assessing your risk and preparing for flood season

To determine if you live in a community that may be impacted by river flooding, please review our flood maps, as well as our river flows, triggers and effects information.
