thumb|Aerial view of the Red River Floodway Winnipeg was inundated during the 1950 Red River Flood and had to be partially evacuated. In that year, the Red River reached its highest level since 1861 and flooded most of the Red River Valley. The damage caused by the flood led then-Premier Duff Roblin to advocate for the construction of the Red River Floodway; it was completed in 1968 after six years of excavation. Permanent dikes were erected in eight towns south of Winnipeg, and clay dikes and diversion dams were built in the Winnipeg area. In 1997, the "Flood of the Century" caused over in damages in Manitoba, but the floodway prevented Winnipeg from flooding.
