The Planning Board was established to ensure integrated management of the principal reservoirs of the Ottawa River Basin:
Recent flow increases from the Abitibi Timiskaming region are still working their way through the Ottawa River system. Levels have peaked from Mattawa down to Lac Coulonge but will continue increasing on Lake Deschenes over the next two days by a further 15 to 20 cm. Flows from the Abitibi-Timiskaming region are already being reduced and river levels are expected to decline through the coming week.
Extreme weather events such as the torrential rain event that occurred in the Timiskaming area on July 15 can lead to very rapid variations in river and lake conditions and can lead to serious consequences for those living along both natural and regulated watercourses. Operations at the control structures along the river do not eliminate flooding and are intended to mitigate their impacts.
You can learn more about the July 15 weather event and the mitigation measures that followed by reading the bulletin available below.
