Despite many streams already peaking or near peak levels, Manitoba's major rivers could still see waters rise with rain forecasted later this week.

Manitoba Transportation and Infrastructure's Hydrologic Forecast Centre has announced the Red River is expected to peak later this week, along with other major waterways such as the Assiniboine and Souris Rivers as water from the United States and Saskatchewan flows into Manitoba.

With rain in this week's forecast bringing approximately 15 millimetres, the centre is anticipating the Interlake and Parkland region, Upper Assiniboine River and Saskatchewan River basins to be affected.

With snow still sitting in western and southwestern Manitoba, and above-freezing temperatures expected, there could be a quick melt and those areas could see increased surface run-off which could lead to overland flooding.

The Portage Diversion is now operational to reduce the risk of ice jamming on the Assiniboine River and to control river levels in Winnipeg, which is working in cooperation with the Red River Floodway as well.

Private well owners are reminded to test wells to determine if action is needed to improve water quality and address potentially harmful bacteria. Testing is recommended at least once a year, particularly after spring run-off and overland flooding recedes. For further details on water testing, visit

The Manitoba Emergency Measures Organization (EMO) continues to work with all local authorities and emergency management partners to provide guidance and support in response to the spring flood. This includes reviewing existing emergency plans, information sharing and preparing resources used in flood response. Additionally, Manitoba EMO continues to work with Indigenous Services Canada to support its response measures with First Nation communities.

As the melt continues, updated flood information will be posted at
