A Flood Watch has been issued for the Lake Nipissing Shoreline in the City of North Bay and Municipality of Callander and a Flood Watch remains in effect for the Mattawa River downstream of the Hurdman dam to the confluence with the Ottawa River and a
Watershed Conditions Statement – Flood Outlook remains in effect for other areas of the North Bay-Mattawa watershed, according to the North Bay-Mattawa Conservation Authority (NBMCA).

“Water levels and flows are high in most areas in response to last week’s rain,” stated Angela Mills, NBMCA Flood Duty Officer. “Water level on Lake Nipissing has increased by 31 cm since April 12. Water level on the Ottawa River in the Mattawa area is expected to stabilize but remain high. Elsewhere, flows and water levels are expected to decrease,” she added.

Lower reaches of Lake Nipissing tributaries (such as Chippewa Creek, Parks Creek, Jessup’s Creek, and La Vase River) will be impacted by high water levels on Lake Nipissing. Strong winds and wave action are a concern while lake levels are high. Flows may increase quickly with any additional precipitation.

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 Friday, April 19, 2024 at 4:00 pm EDT.
