The 1950 Red River flood was a devastating flood that took place along the Red River in The Dakotas and Manitoba from April 15 to June 12, 1950. Damage was particularly severe in the city of Winnipeg and its environs, which were inundated on May 5, also known as Black Friday to some residents.
An estimated 70,000–100,000 residents had to be evacuated, and four of eleven bridges were destroyed. In that year, the Red River reached its highest level since 1861 and flooded most of the Red River Valley, more than 1,400 km2 (550 sq mi). One man died, and property losses due to the flood were estimated at more than $600 million to one billion.
To prevent and reduce future damage, the government constructed the Red River Floodway, which was completed in 1968. It has been estimated to have prevented more than $100 billion (CAD) in cumulative flood damage.
Although seasonal flooding was common, this flood surpassed the others. The north-flowing Red River was fed by flows resulting from melting of heavy snows in the winter and runoff from heavy rains in the spring. Eight dikes gave way and flooded much of Winnipeg, turning an estimated 600 square miles (1,600 km2) of farmland in the area into an enormous lake. A total of more than 1,400 km2 (550 sq mi) in the Red River Valley were flooded, from Emerson to 60 miles (97 km) north to Greater Winnipeg. The depth of the flood waters on the farmland was between 2–6 feet (0.61–1.83 m). The city turned to the Canadian Army and the Red Cross for help.
In the end, four of eleven bridges in the city were destroyed and nearly 100,000 people had to be evacuated from their homes and businesses. This was the largest evacuation in Canadian history until the 1979 Mississauga train derailment. In Winnipeg there was one fatality; property damage was severe, with losses estimated at between $600 million and more than a billion dollars.
As a result of the widespread damage, the government built the Red River Floodway, to divert flood waters from Winnipeg to more distant portions of the river. The project was completed in 1968 and has been used 20 times. From 1950 to about 1997, it was derogatorily referred to as "Duff's Ditch", after the premier (Dufferin Roblin) that built the floodway. It is estimated to have prevented more than $100 billion (CAD) in cumulative flood damage. The Floodway was designated a National Historic Site of Canada in 2000, and is considered an outstanding engineering achievement both in terms of function and effects.
Flooding in the Red River Valley of the United States resulted in five deaths.
