Spring thaw has officially begun across southern Manitoba, and provincial officials are warning that ice conditions are deteriorating rapidly—including on the Assiniboine River, the Little Saskatchewan River, and retention ponds throughout Brandon. Manitoba Transportation and Infrastructure’s Hydrologic Forecast Centre says warming temperatures are increasing river flows and weakening ice across the region, even in areas where surfaces may still appear solid.
The province notes that ice can look similar to normal winter conditions but may now be extremely thin and unpredictable. That creates a significant risk for anyone walking, skating, sledding, or snowmobiling on or near frozen waterways.
In Brandon, where the Assiniboine runs directly through the city and several neighbourhoods back onto retention ponds, officials are urging residents to keep a close eye on children and pets and to stay well back from the banks.
As daily temperatures continue to rise, the quality and thickness of river ice are expected to deteriorate quickly. The province says the strength of ice within communities is especially uncertain at this time of year, and even areas that supported weight earlier in the season may no longer be safe. Residents are advised to avoid all rivers, lakes, drainage ditches, and stormwater ponds until conditions stabilize.
The Manitoba Emergency Management Organization is working with municipalities, First Nations, and emergency partners to prepare for potential spring flooding. That work includes reviewing emergency plans, sharing updated hydrologic information, and ensuring resources are ready should river levels rise more quickly than expected. While no immediate flood concerns have been issued for Brandon, officials say preparation and caution are key as the melt progresses.
Updated flood forecasts, river conditions, and provincial advisories will continue to be posted at www.manitoba.ca/floodinfo as the spring thaw advances.
