Manitoba’s Hydrologic Forecast Centre has released its second 2022 spring flood outlook. The risk of major flooding on the Red River and tributaries remains high flood preparation activities are underway. Though significant high water activity is expected in southern Manitoba, flood water levels are expected to remain below community flood protection levels with water levels to be influenced by the rate of snowmelt and future snow and rain accumulation.
There is also a risk of moderate flooding on the Assiniboine and Souris rivers and tributaries.
The risk of flooding in the Interlake region and northern Manitoba is low, with the risk of lakes flooding due to spring run-off remaining low, except for the Whiteshell Lakes area, which has a potential for moderate flooding.
With normal weather, water levels similar to 2020 are expected on the Red River. With the use of the Red River Floodway and the Portage Diversion, water levels at James Avenue in Winnipeg could reach 19.5 feet with unfavourable weather.
The Portage Diversion may be operated to prevent ice jamming on the Assiniboine River east of Portage la Prairie to control river levels in the city of Winnipeg and areas along the Assiniboine River downstream of Portage la Prairie.
Updated flood information will be shared next week.
