The latest hydrological forecast released by Manitoba Infrastructure on March 31, 2020 (available here), shows that there is a higher risk of major flooding across southern Manitoba and southeastern Manitoba this spring for the Red River basin, including the following rivers:
Roseau River
Red River
Pembina River
The risk of major flooding is low for most Manitoba basins including the following rivers:
Assiniboine
Souris
Qu'Appelle
Saskatchewan River
"Due to the above normal to record high soil moisture at freeze-up in southern and central Manitoba and normal to above normal winter precipitation to the middle of March in the U.S. portion of the Red River basin, the Red River Valley is at a higher risk of major flooding. There is a high risk of moderate flooding for southern and southeastern Manitoba, including the Roseau River and the Pembina River. However, the flooding risk level could change depending on weather conditions between now and the spring melt".
The Red River at Oslo, north of Grand Forks in North Dakota is already showing major flood stage as of April 4, 2020.
