Flood Watch – Ice Jamming

Due to observations of ice jams, Maitland Conservation is issuing a Flood Watch for all municipalities in the Maitland and Nine Mile River watersheds.

While most smaller streams throughout the watershed are ice-free, signs of ice jams have been observed in larger river reaches. Jams have been reported on the Lower Maitland River near Wingham, the South Maitland River near Summerhill and the Nine Mile River in Port Albert. As of early this morning, river levels have either peaked or are nearing peak flows; however, with fast falling temperatures there’s risk of blockages from ice jams freezing in place.

Ice jams are unpredictable - they can form, shift, worsen or breakup suddenly. These blockages cause rapid changes in water levels and localized flooding, even in non-traditional areas. While Maitland Conservation will monitor known ice jams, there’s risk that unknown or new jams may form elsewhere in the watershed.

Municipal officials are encouraged to check low-lying roads and infrastructure. We remind people that conditions around all watercourses remain hazardous.

Maitland Conservation is monitoring watershed conditions and will provide an update if warranted.

This message is in effect until the afternoon of Friday March 7, 2025.
