The Planning Board was established to ensure integrated management of the principal reservoirs of the Ottawa River Basin:
Water levels and flows on the main stem of the Ottawa River (between Lake Timiskaming and Pembroke) are expected to increase rapidly in the next few days in response to forecast rainfall of 40 to 80 mm over a large portion of the basin. Levels and flows in downstream locations, particularly on Lac Deschenes, are expected to continue increasing into the coming weekend. Levels may increase rapidly depending on location but will remain below flood thresholds along the main stem of the Ottawa River. This river conditions message will be revised on Thursday.
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.
