Flood Warning Now Issued - Update April 23 (12 noon)

(April 23, 2019)  Flood Warning extended to Thursday, April 25, 4 pm.   Water levels within local watercourses are elevated due to the recent rains combined with snowmelt.  Water levels are expected to continue to rise over the next couple of days with the forecast precipitation and continued snowmelt.  Urbanized watercourses such as Chippewa Creek are returning to more normal levels but may respond quickly to any intense rain event, and rural watercourses and lakes are expected to continue to rise with the forecasted precipitation and continued snowmelt.

Flood Watch Issued

(April 17, 2019)  It’s the rain event we were hoping wouldn’t come, but with 35 to 55mm of rain and warmer temperatures adding to the spring melt, this weather system will tip the scale and bring flooding to area rivers and streams, prompting North Bay-Mattawa Conservation Authority (NBMCA) to issue a Flood Watch.
