The flood warning has been extended until next Wednesday for the North Bay area by both the North Bay-Mattawa Conservation Authority and the Ministry of Natural Resources and Forestry.

Lake Nipissing could rise another 22 cm and the Mattawa River could climb another 43 cm due to the snowmelt in the northern watersheds and the 30-50 mm of rain in the forecast for Thursday.

A rainfall warning continues for the North Bay area with rain, heavy at times, expected to taper to scattered showers on Friday.

It’s all thanks to a low pressure system tracking across the Northeast Region.

Kurtis Romanchuk, NBMCA Duty Officer says increasing outflow from reservoirs in the Abitibi-Timiskaming region are causing Ottawa River levels to rapidly rise which raises the level of the Mattawa River impacting properties in Mattawa, Papineau-Cameron and Mattawan Townships along the river.

Lake Nipissing is currently at 196.37 m near North Bay, and is forecasted to continue to rise until its peak in approximately two weeks.


Here in North Bay, city officials have installed temporary piping by the wastewater treatment plant to allow for treated effluent to be pumped out if needed.

Memorial Dr. and the Kate Pace Way are closed between Monk and Regina Streets, with a detour in place.

Sand and sandbags are also available in flood-prone areas.


As the state of emergency continues in Mattawa because of the flooding situation, the Canadian Red Cross has announced financial assistance for affected residents there.

They will be at the Legion on Hurdman Street Thursday morning from 9 am to 11 am for registration.

Flooding conditions in Mattawa continue to pose a threat with officials monitoring water levels.


In West Nipissing, the municipality will provide 100 sandbags per residence to those in need.

Officials say properties in low-lying areas are most at risk for flooding and road closures.

Residents at risk are instructed to take necessary precautions to mitigate damage to their properties and to prepare for a potential evacuation.
