Ottawa River Regulation Planning Board

The Planning Board was established to ensure integrated management of the principal reservoirs of the Ottawa River Basin:

  • to reduce flood and drought impacts along the Ottawa River and its tributaries, all the way down to the Montreal Region
  • while maintaining beneficial water uses in the basin.

River Conditions Forecast

Last Update: 2025-06-25 3:27 PM
Next Update: 2025-07-02 4:00 PM

Flows and water levels along the main stem of the Ottawa River are above average for this time of year in most locations due to recent rainfall. Forecast precipitation later this week is expected to delay the decline in water levels and flows. Over the next few days and into the weekend, levels and flows are expected to stabilize at and upstream of Lake Deschenes (Britannia), and to continue increasing slightly downstream of that location. Later next week, flows and water levels are expected to decrease in most locations.  Please take note of an important message from the ORRPB that is posted on the website Home page in the SPECIAL FEATURE section.

Special Feature

Summertime ORRPB message

In both Ontario and Québec, citizens have the primary responsibility for their safety, the safety of their property and the safety of the activities in which they engage.

Heavy rains can cause the Ottawa River levels to rise rapidly and without warning.

A general message describing current and forecast river conditions is posted weekly on our website, on Tuesday, throughout the summer.  If the message is revised thereafter due to significant change in weather and flow conditions, a post is sent to the platform “X”.
