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”.
