Floods and river ice break-up

Black and white satellite image of a river showing flooded areas around the river in turquoise.

The Government of Canada response to ice break-up and flood events is managed by the Government Operations Centre at Public Safety Canada and the Department of National Defense. Flood forecasts are available through regional and provincial flood forecasting centres across Canada.

Natural Resources Canada’s Emergency Geomatics Services (EGS) provides critical, near real-time information to Public Safety Canada and emergency responders during ice break-up and flood events. EGS flood extent maps and river ice state maps are available to the public on Open Maps.

Flood research and mapping

NRCan works with partners across the country to increase the knowledge base about river ice break-up and floods and to improve the ability of authorities to predict and manage flood risk:

  • CCRS is using very high resolution imagery to develop Earth Observation-based methodologies for mapping urban floodplains for flood risk analysis, mitigation and disaster response. This research is supported by Public Safety Canada, and uses geospatial data from the 2013 Calgary flood made available to NRCan under a Data License Agreement with the City of Calgary.
  • With Public Safety Canada, CCMEO is developing the Federal Floodplain Mapping Guidelines Series to advance and standardize floodplain mapping activities across Canada. This will improve the accuracy of floodplain maps to support planning and emergency response.
  • NRCan’s Adaptation to Climate Change Program facilitates the development and exchange of information, knowledge, and tools needed to plan and implement practical adaptation measures that increase the resilience of Canadian communities and industry to climate change, including more frequent flood events.
