Flood officials in our province say they continue to prepare for flooding in the Red River Valley that is similar to 2009 between Emerson and the Red River Floodway.

Manitoba Transportation and Infrastructure's Hydrologic Forecast Centre continues to monitor flood activity as water levels on streams and tributaries in most of Manitoba may continue to be impacted by run-off from recent precipitation. Although water levels on smaller creeks and drains are beginning to stabilize, many larger rivers and streams are continuing to rise as water moves through the system.

Water levels are expected to remain high for an extended duration in many areas in southern and central Manitoba.

Overland flooding continues in the Interlake, Red River Valley and many other portions of central and southern Manitoba. Residents in these areas are advised to monitor local conditions and to take any necessary flood mitigation actions. Little to no precipitation is expected in southern and central Manitoba for the next four days.

Since April 1, southern and southeastern Manitoba and the United States portion of the Red River basin have received 120 to 160 millimetres (mm) of precipitation, which is between 400 to 600 per cent of normal amounts.

The Manitoba Emergency Measures Organization (EMO) continues to work with all local authorities and emergency management partners to provide guidance and support for response and recovery activities.

Several communities throughout the province continue to be impacted by high water levels. Reported impacts to date include loss of road access, flooded properties and damage to infrastructure. As a result of these impacts, seven municipal emergency operations centres have been activated and states of local emergency have been declared in the following 18 communities:

  • Rural Municipality (RM) of Cartier;
  • RM of Morris;
  • RM of Ritchot;
  • RM of Fisher;
  • RM of Montcalm;
  • City of Morden;
  • Town of Winnipeg Beach;
  • Municipality of Pembina;
  • Town of Arborg;
  • RM of Armstrong;
  • RM of Dufferin;
  • Municipality of Bifrost-Riverton;
  • RM of Grey;
  • RM of Headingley;
  • RM of Thompson;
  • RM of West Interlake;
  • RM of St. Laurent; and
  • RM of Grahamdale.

Manitoba EMO continues to work with Indigenous Services Canada (ISC) in supporting ISC-led response measures with First Nation communities.

Provincial Trunk Highway (PTH) 75 has been closed at the north end of Morris since April 29 with a detour in place to redirect PTH 75 traffic to Provincial Road (PR) 246. PTH 75 on the south side of Morris will also close Friday at 8 pm. A detour utilizing PTH 3 through Carman and south to Winkler and onto PTH 14 to return to PTH 75 will now be in effect. Additional detour information is available at www.manitoba511.ca or by calling 511.

Warnings and high water advisories in effect include:

  • An overland flood warning for the Interlake and portions of southern and central Manitoba as highlighted in the attached map remains in place and has been extended to include all of eastern Manitoba. Most ditches and waterways are either full or near capacity.The recent heavy rain and saturated soils are creating overland flooding in many areas.
  • A flood warning remains in place for the Red River from Emerson to the Red River Floodway inlet and from the Red River Floodway channel outlet to Lake Winnipeg.
  • A flood warning remains in place for all Red River tributaries including the La Salle, Pembina and Boyne rivers and the Deadhorse, Shannon and Netley creeks.
  • A flood warning continues for the Fisher River. Officials advise the Fisher River flow has now peaked but ice jamming continues to be a risk.
  • A flood warning remains in place for the Icelandic River and Sturgeon Creek.
  • A flood watch remains in place for streams in the eastern region and continues for the Roseau and Whitemud rivers.
  • A flood warning is issued for the Whiteshell lakes area as levels on most lakes continue to rise due to the recent rain and snowmelt.
  • A flood warning for the Assiniboine River has been expanded to include the area from the Shellmouth Dam to Brandon.

Provincial crews are deployed to a number of communities in southern Manitoba running pumping operations as well as preparing for, monitoring and implementing dike closures as required. Manitobans are reminded to stay off waterways including creeks, streams, rivers and the floodway. High flows, debris and cold temperatures present a significant safety risk.
