River Ice in Canada - Current Year

Current year record of river ice roughness as monitored on selected rivers by Natural Resources Canada (NRCan) using satellite imagery for the mitigation of ice jam associated risks.

In order to mitigate ice jam induced floods risks, Natural Resources Canada emergency geomatics service (EGS) may be activated by Canada’s emergency management authorities. As new satellite imagery becomes available, NRCan will produce river ice roughness maps and update the dataset in near real time (4 hours). This item contains record of the river ice roughness products generated in the current year. For the complete archive, please refer to the River Ice in Canada - Archive entry.

The river ice product is generated and validated on a best effort basis. Various factors may affect the quality of the river ice roughness maps. Those factors include but are not limited to: environmental condition at the time of acquisition, image resolution or the limitations of the methodology used.

To view a specific product, filter the data by date (UTC Date) and area of interest (AOI). Links to download specific EGS product are available in the Resources section.

Disclaimer:

Emergency response authorities are the primary users of these satellite-derived river ice roughness map products. These products are generated to provide analysis and emergency response situational awareness and to facilitate decision-making during major flood events. The river ice roughness products are generated rapidly and limited time is available for editing and validation. The river ice roughness products reflect the river ice surface roughness conditions at the date/time of acquisition. While efforts are made to produce high quality products, near-real time products may contain errors due to the limited time available for validation and the limited availability of ground truthing data.
