The Hydrologic Forecast Centre of Manitoba Transportation and Infrastructure has issued a warning to residents across southern Manitoba, highlighting the increasing dangers posed by thinning ice as the spring thaw commences. With rising temperatures impacting river basins, including the United States portion of the Red River basin, the public is urged to exercise extreme caution around waterways.
“While the ice may appear solid, it is rapidly deteriorating,” stated a spokesperson from the Hydrologic Forecast Centre. “The ice is no longer safe and will not support the weight of people or heavy objects like snowmobiles and vehicles. We are seeing a gradual increase in river flows and water levels, which further weakens ice integrity.”
The Centre specifically highlighted the Assiniboine River, noting that outflows from the Shellmouth Dam are being reduced from 680 cubic feet per second (cfs) to 300 cfs. This operational adjustment, while routine, is expected to contribute to the weakening of ice along the river from Shellmouth to Brandon.
Residents are strongly advised to avoid all recreational activities on rivers, lakes, floodways, and drainage ditches, including skiing, sledding, and snowmobiling. Special attention should be paid to preventing children and pets from venturing onto the ice.
“The daily warming trend is significantly impacting ice thickness and strength,” the spokesperson emphasized. “The quality of river ice, even within communities, is unpredictable. Citizens must stay off rivers and retention ponds to ensure their safety.”
In parallel to the ice warning, the Manitoba Emergency Management Organization (EMO) is actively collaborating with local authorities and emergency management partners to prepare for potential spring flooding. This comprehensive effort includes reviewing existing emergency plans, disseminating crucial information, and mobilizing resources for flood response.
Manitoba EMO is also working closely with Indigenous Services Canada (ISC) and Municipal and Northern Relations (MNR) to support preparation activities in First Nations and Northern Affairs communities.
As the province transitions into the spring thaw, residents are urged to remain vigilant and heed the warnings issued by authorities to prevent accidents and ensure public safety.
