What happened
The Portage Diversion project, a major flood protection measure in Manitoba, was ranked third among options on September 23, 2026. The idea of diverting water away from the Assiniboine River near Portage la Prairie was discussed as early as the 1940s, with the 1950 Red River flood adding urgency to the search for better flood protection across southern Manitoba.
