A Flood Watch continues for the Lake Nipissing Shoreline in the City of North Bay and Municipality of Callander. A Flood Watch on the lower reaches of the Mattawa River has ended. A Watershed Conditions Statement – Flood Outlook remains in effect for other areas of the North Bay-Mattawa watershed, including the Mattawa River below Hurdman Dam, according to the North Bay-Mattawa Conservation Authority (NBMCA).

“Average water level on Lake Nipissing continues to rise in response to inflows from last week’s rain event,” stated Angela Mills, NBMCA Flood Duty Officer. “Lower reaches of Lake Nipissing tributaries (including as Chippewa Creek, Parks Creek, Jessup’s Creek, and La Vase River) will be impacted by high water levels on Lake Nipissing. The forecast winds will trigger higher water levels and increased wave action along the Lake Nipissing shoreline, heightening the risk for shoreline erosion.,” she added.

Landscape conditions with dormant vegetation and saturated soils have limited capacity to store additional moisture. Local rivers may respond rapidly to precipitation. Easterly winds have caused water level fluctuations in North Bay as the water is pushed to the West. As the winds change direction becoming southwesterly or westerly today, the water in Lake Nipissing will be pushed back towards the East.

The public is encouraged to keep children and pets away from watercourses and shorelines. Area residents and visitors, especially those in low-lying areas, are encouraged to monitor the conditions as they develop and take proper precautions during times of high water levels. If you have a flood emergency, please contact your municipality. If you live in an unincorporated township, please contact the Ministry of Natural Resources and Forestry – North Bay District.

As part of the NBMCA Flood Forecasting and Warning Program, staff will continue to monitor weather and watershed conditions and update this message if needed based on the changing weather/streamflow conditions. Staff remain in contact with municipalities and other partners as required.

The general public is advised of these messages through the www.nbmca.ca website with the flood status icon and a link to information about current conditions. NBMCA also circulates these messages to local media and social media, posting on X (@theNBMCA), Facebook (@theNBMCA) and Instagram (nbmcainfo).

This message will be in effect until Monday, April 22, 2024 at 4:00 pm EDT.
