With Water Levels Increasing, Freshet Task Force Shifts Focus to the Ottawa River

April 24, 2025

The Freshet Task Force has been slowly shifting its focus from the smaller local waterways to the Ottawa River.  

Ottawa River 

Water levels and flows are gradually increasing at several locations along the main stem of the Ottawa River. Levels and flows will continue to increase over the next few days due to increased spring runoff and rain expected to start Thursday. 

The ORRPB continues to provide four-day forecasts which can be found at www.ottawariver.ca/forecasts.

Rideau River and small waterways 

Water levels and flows along our smaller waterways have generally declined to within expected seasonal norms. As a result, the risk of flooding along small waterways within the Ottawa area remains low at this time. That said, the Rideau River and small waterways may respond quickly to significant precipitation events requiring ongoing caution.  

Check the Basement and Overland Flooding page for safety and prevention measures. 

Please continue to keep children and pets away from creeks and waterways.

As a reminder, updated information on freshet operations, impacts, and resources can be found on Flooding | City of Ottawa. 

Sandbag filling stations remain in place for residents to prepare for flooding if needed. Residents can contact 311 should there be a need to replenish supplies at any of the existing sandbag filling locations. https://www.ottawa.ca/en/flooding/river-flooding 

Looking ahead 

The Freshet Task Force is expecting water levels and flows to increase over the coming days along local segments of the Ottawa River. We continue to monitor weather forecasts and water statements related to the Ottawa River and the Ottawa River catchment area. Minor flood levels may be exceeded in flood prone areas along the river between Lake Coulonge and Carillon starting Saturday, April 26. The minor flood level is defined as the level at which parts of some streets, lawns and parks are beginning to flood, with no or few houses/buildings being affected. 

We encourage residents to remain vigilant and to regularly monitor water statements, levels, and forecasts. 

Improvements to our riverine flood preparation information for residents are expected to be released as part of our end-of-week update. As always, please feel free to reach out with any questions related to spring freshet activities.
