Manitoba residents are keeping a close eye on rising temperatures as the province’s Hydrologic Forecast Centre released its spring flood outlook, indicating a low to moderate risk for most regions. While many areas are expected to see minimal flooding, certain river systems and the Interlake region are under a moderate flood warning.
The centre’s report highlights a moderate risk for the Assiniboine River main stem from Russell to Brandon, the Souris River, the Qu’Appelle River, and the Interlake region, including the Fisher and Icelandic Rivers. A low, or minor, flood risk is projected for the Red River, Pembina River, Rat River, Roseau River, Winnipeg River, Saskatchewan River, Churchill River, Carrot River, Swan River, and the Whiteshell Lakes area.
“Spring flood risk is largely dependent on weather conditions from now until the spring melt and throughout the spring,” stated the Hydrologic Forecast Centre.
The centre is currently tracking a precipitation system that could deliver up to 15 cm of snow across central and southern Manitoba basins. This potential snowfall has been factored into the current flood outlook.
To mitigate potential flooding, minimal operation of the Red River Floodway and the Portage Diversion may be necessary. The Shellmouth Dam is being managed in collaboration with the Shellmouth Dam liaison committee to balance flood control with recreational and water supply needs.
Ice-cutting and breaking activities have concluded on the Red and Icelandic rivers, with similar operations scheduled for the Fisher River this week.
As temperatures rise and ice conditions deteriorate, residents are strongly advised to stay off waterways, rivers, and retention ponds.
The Manitoba Emergency Management Organization (EMO) is working closely with local authorities and emergency management partners to ensure preparedness. This includes reviewing emergency plans, disseminating crucial information, and preparing flood response resources. EMO is also collaborating with Indigenous Services Canada (ISC) and Municipal and Northern Relations (MNR) to support preparation efforts in First Nations and Northern Affairs communities.
While most lakes are expected to remain within their desired operating ranges after the spring runoff, the moderate risk in specific river systems and the Interlake region necessitates vigilance. Residents in these areas are urged to stay informed and follow any advisories issued by local authorities.
