Get Prepared for a Flood in British Columbia

Floods are common in B.C. and can happen at any time of year. The most severe floods usually occur in spring and early summer due to heavy rain and melting snow. This seasonal flooding is known as freshet. They can also be caused by storm surges, ice jams or damage to structures like dikes or dams.

In some areas of B.C., climate change and related extreme weather events have increased the flood risk. Rising temperatures, changing freeze-thaw cycles and rising sea levels can all contribute to flooding.

Floods can damage buildings, cause power outages, disrupt transportation and create landslides. Fast-moving flood waters can also be a hazard for people.


Stages of a Flood

Depending on the type and severity of flooding, it could take weeks and potentially months for the water to recede. It’s important to take time to prepare and understand what to do before, during and after a major flood:
