The Ministry of Natural Resources and Forestry – Pembroke District is advising area residents that a Flood Warning remains in effect for the Ottawa River until Friday, May 12, 2023.
Residents along the main stem of the Ottawa River, should Consider the following:
The water levels and flows along the Ottawa River remain elevated in response to last weekend’s precipitation, and most river systems that drain into the Ottawa River have peaked or are now receding. Remnants of the snowpack through the central portions of Northeast and Northwest Regions are expected to continue melting slowly, sustaining elevated levels and flows currently occurring in those region’s drainage networks. Water levels along the Ottawa River are expected to remain high through the coming week, and flood levels that have been observed in some localities is expected to continue
Residents that have been affected by high water and flow conditions in the past should continue to maintain necessary action to protect/secure any vulnerable property in proximity to rivers and lakes and closely monitor developing conditions and regularly check for updated messages.
Residents and visitors should exercise caution while around waterbodies and maintain close supervision of children and pets.
The ministry is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.
