Ice Jams Impacting Lower Maitland and Nine Mile Rivers

A polar vortex has brought frigid air to the area and will persist well into the week. The combination of streamflow from the previous brief thaw and cold air temperatures may cause frazil ice formation. This will heighten the risk of ice jamming and localized flooding in areas prone to this issue including Port Albert.

It is difficult to predict where ice jams will form and how long they will persist. Residents are reminded not to attempt to drive or walk through flooded areas. Conditions can change rapidly, and access routes can quickly be cut-off.

Maitland Conservation staff will be closely monitoring conditions, particularly in the Port Albert area, over the next week and will provide an update if conditions change.

This message will remain in place until 4:00 p.m. on Friday January 30, 2026.
