Spring Flood Outlook Remains High for Manitobans

Warm temperatures have initiated spring thaw and surface run-off in most areas of Manitoba according to Manitoba's Transportation and Infrastructure’s Hydrologic Forecast Centre. River levels are expected to continue to rise in the next week as the ice continues to melt. The flood forecast remains consistent with the spring outlook issued on March 22, which indicated a major flood risk for the Red River between Emerson and the Red River Floodway inlet. The Red River Floodway is expected to reduce water levels within Winnipeg. The Portage Diversion is also anticipated to minimize and reduce the effects of ice jamming on the Assiniboine River east of Portage la Prairie and control river levels in Winnipeg and areas along the Assiniboine River downstream of Portage la Prairie.

The flood risk remains low to moderate in the Interlake region along the Fisher and Icelandic rivers, and along the Assiniboine River. The risk of spring flooding is generally low along several other rivers including the Souris, Roseau, Rat and Pembina rivers. Water levels are expected to remain below community and individual flood protection levels. The flood protection level of community dikes and individual flood protection works in the Red River basin are higher than predicted flood levels and are expected to protect communities and properties in the region.

There is also a low risk of flooding for most other Manitoba basins including the Saskatchewan River, Whiteshell lakes area and northern Manitoba. With the exceptions of Dauphin Lake and Lake St. Martin, most Manitoba lakes, including Lake Winnipeg and Lake Manitoba, are projected to remain within operating ranges after the spring run-off. As always, the risk of flooding could change in any of the basins depending on weather conditions in the next few weeks.
