NBMCA issued a Flood Warning on April 21 for waterways in our jurisdiction and it remains in effect.
The combination of snowmelt, precipitation and already high water levels in area streams and rivers have created flooding conditions throughout the watersheds within NBMCA's jurisdiction (see map).
(Please note NBMCA does not provide flood forecasting for the Parry Sound District.)
Updates on the status of the flood forecast are posted on our website under
Spring 2019 Flood Event Updates and the "News" section below.
If you think that your property may be at risk of flooding, please contact your municipality.
If you live in an unorganized township in Nipissing District, contact the Ministry of Natural Resources and Forestry District office at 705-475-5529.
Please share photos of conditions in your area using #NBMCAFlood on all social media and include the location of the photograph.
Thank you. NBMCA Communications & Outreach. 705-474-5420
