Message:
Due to the extreme cold temperatures over the past week, with cold temperatures expected to continue through the coming weekend, combined with the fact that the Beaver River still has not fully frozen over throughout the system, frazil ice continues to be generated within the upper reaches of the river. Municipalities are challenged with the potential for localized flooding in two separate areas as noted:
CLARKSBURG – TOWN OF THE BLUE MOUNTAINS
Over the last week, frazil ice has collected in the Beaver River within Clarksburg which has caused water levels to rise. While water levels have decreased slightly, they still remain high at this time. With windchill temperatures forecast to remain near or below –18C into the weekend, with only small warmer periods during the day, the potential exists for frazil ice to continue being produced upstream of Clarksburg until the Beaver River freezes over.
At this time, the frazil ice sheet has extended upstream of Marsh Street and there is concern that flows will be further restricted causing water levels to rise over the next few days. This area will continue to be monitored by Town and GSCA Staff. Town of the Blue Mountains crews and contractors are utilizing a long-reach excavator to remove frazil ice from the river to promote flow, despite limited access to the river. The frazil ice removal is expected to continue throughout the daytime hours.
UPDATE: LOWER VALLEY ROAD – MUNICIPALITY OF GREY HIGHLANDS
The frazil ice-related flooding along Lower Valley Road, just south of Graham’s Hill/Campbell’s Hill roads, has now cleared. Water levels have receded on the Beaver River, and Lower Valley Road has reopened to traffic. GSCA and municipal staff will continue to monitor conditions in the area.
Flood Watches are issued when flooding is possible along local watercourses. Landowners within these areas should monitor their situation and be prepared in case of flooding.
Grey Sauble Conservation Authority reminds everyone that flooding can lead to unsafe conditions along rivers and streams. Fast moving water, slippery or unstable banks, and melting ice can present significant safety risks. Please stay alert and avoid watercourses when flows are high.
GSCA staff will continue to monitor the weather and the flows and provide additional updates as needed.
This Statement expires Monday, February 2nd, 2026 at 4:30pm unless replaced by further updates.
