WINNIPEG – Days after the Red crested in Winnipeg, the province continues to prepare for the Assiniboine to reach capacity.
Water flows will increase substantially in the coming days, with the Portage Diversion peaking near the end of next week.
But Lee Spencer with Manitoba’s emergency management team says that people along that river shouldn’t be too worried.
“We have a pretty good idea of where the water will go. In 2011 and 2014, we saw water over the bank in those areas as well. Along with local knowledge, we’ve already identified the properties that are at risk. People will be working throughout the weekend to make sure flood protections are in place.”
A flood watch still remains for Portage la Prairie and Headingley.
Based on natural Red River flow at James Avenue, the province says this year’s flooding was a once-in-13-years event.
“The cause of ice jamming is due to a number of factors such as thick strong ice that is subjected to an early spring runoff,” explains Doug McMahon with Manitoba Infrastructure. “Due to the unusually warm temperatures this year, the spring runoff was two weeks earlier than usual and the runoff rates were exceptionally high.”
Flood warnings remain in place for the upper Assiniboine from the Shellmouth Dam to Holland; Pelican, Rock, Oak and Dauphin Lakes; and the Pembina and Souris rivers.
