Snow Conditions in the Ottawa River Basin – Now available!

Our website provides a map that will help you keep track of the snow cover in the watershed. The map of the snow water equivalent is available on the Current Conditions webpage (at the top of the interactive map) or can be found by clicking here.

Snow measurements are done on a regular basis at over 100 sites across the basin. The snow map provides an overview of conditions at the time of the most recent snow measurements. It shows the amount of water held in the snow cover compared to the amount of water it normally holds at this same time of year. This amount of water is called ‘snow water equivalent’. The map covers the entire Ottawa River watershed. At a glance, it is possible to see if there was more or less snow than usual at a given time of the year.

This map will be updated in early March, and every two weeks thereafter.

Note: Recent snowfalls or thaws that have caused an increase in snow cover or melting of part of the snow cover may not have been represented in the map. Therefore, the conditions shown on the map may not perfectly reflect current field conditions.
