Low Water Level 1 Condition

November 01, 2024

Due to lower than normal precipitation and streamflow, Low Water Level 1 Condition has been confirmed for the NBMCA jurisdiction, according to the North Bay-Mattawa Conservation Authority (NBMCA).

“We have experienced drier than normal conditions since the end of July. The lack of rainfall has led to low streamflow across the watershed,” stated Angela Mills, NBMCA Duty Officer. “Water levels and streamflow are generally lowest in August and rise through the autumn, but this year, they have continued to drop.”
