Get Prepared for a Flood in British Columbia
Flooding is a common, naturally occurring event in B.C. Although it can happen at any time of year, the most severe floods typically occur in spring due to heavy rain and snowmelt. This seasonal flooding is known as freshet.
Floods can also be caused by storm surges, ice jams or damage to structures like dikes or dams. Depending on the type and severity of flooding, it could take hours, weeks and potentially months for the water to recede.
