The Ottawa River Regulation Planning Board issued a statement on Apr. 13 forecasting a rapid increase in river levels from Pembroke to Montreal due to the heavy rainfall that began Sunday evening. 

“Water levels and flows are expected to increase more rapidly compared to last week at all locations along the main stem of the Ottawa River over the next few days,” the statement reads.  “Warmer forecast temperatures, combined with rainfall and runoff is expected to accelerate snowmelt across much of the basin.”

The statement adds that flooding is possible in low-lying areas along the river (locations that regularly flood during the freshet).

The Pembroke district of Ontario’s Ministry of Natural Resources issued a flood watch on Apr. 10, advising caution. 

“Although no widespread flooding is expected at this time, water levels and flow in the inland areas of Renfrew County will increase, and flooding in low-lying areas and areas with poor drainage is possible,” the statement notes. “Residents in flood-prone areas are encouraged to closely follow changing conditions and to take necessary measures and exercise caution around rivers and streams. Please alert and monitor any children under your care to possible dangers and supervise their activities.”
