The Planning Board was established to ensure integrated management of the principal reservoirs of the Ottawa River basin:
To learn more about the Planning Board, see the presentation: Flow Management in the Ottawa River Basin – 2024
Water levels and flows along the main stem of the Ottawa River are close to seasonal values and are expected to remain fairly stable over the coming week.
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 (click on the “Snow Map” button at the top of the interactive map).
Snow measurements are done on a regular basis at over one hundred (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.
