A flood watch remains in effect for the Township of Ashfield-Colborne-Wawanosh as ice-related conditions increase the risk of localized flooding along area waterways.
Maitland Conservation says the advisory, first issued January 25, continues due to prolonged cold brought on by a polar vortex. Officials note that runoff from a recent short-lived thaw, combined with sustained frigid temperatures, is creating conditions favourable for frazil ice to develop in rivers and streams. That ice can accumulate quickly, raising the likelihood of ice jams and flooding in locations that have seen similar problems in the past.
Water level gauges near Benmiller and along Sharpes Creek Line are already showing a rapid rise, which conservation staff believe is the result of ice obstructing normal flow. Residents in affected areas are being urged to avoid travelling through flooded roadways or walking through standing water, as conditions can shift quickly and routes may become impassable with little warning.
Conservation officials say forecasting the exact location or duration of ice jams is challenging. As a precaution, staff with the Township of Ashfield-Colborne-Wawanosh are being advised to keep a close watch on bridges, culverts, and other crossing structures for signs of ice buildup and localized flooding.
Maitland Conservation will continue monitoring conditions closely, particularly in the Port Albert and Benmiller areas, over the coming week. An updated notice will be issued if the situation changes.
The current flood watch is set to remain in effect until 4 p.m. on Friday, January 30, 2026.
