The Planning Board was established to ensure integrated management of the principal reservoirs of the Ottawa River Basin:
Water levels and flows along the main stem of the Ottawa River remain above average for this time of year. They are expected to increase in most locations over the next few days due to recent precipitation and to additional precipitation in the forecast. Rapid increases is possible in some locations. Please take note of an important message from the ORRPB that is posted on the website Home page in the SPECIAL FEATURE section.
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”.
