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. [3]
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. 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). [5] The city turned to the Canadian Army and the Red Cross for help.
Four of eleven bridges in the city were destroyed and approximately 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 [1] and more than a billion dollars. [3] The flood postponed opening day for baseball in the Mandak League due to inundation of Osborne Stadium. [6] The league and its president Jimmy Dunn arranged benefit games to raise money for Winnipeg's Flood Fund. [7]
As a result of the 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. [8] 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. [9]
Flooding in the Red River Valley of the United States resulted in five deaths. [2]
The Red River, also called the Red River of the North to differentiate it from the Red River in the south of the continent, is a river in the north-central United States and central Canada. Originating at the confluence of the Bois de Sioux and Otter Tail rivers between the U.S. states of Minnesota and North Dakota, it flows northward through the Red River Valley, forming most of the border of Minnesota and North Dakota and continuing into Manitoba. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into Hudson Bay.
The Red River Floodway is an artificial flood control waterway in Western Canada. It is a 47 km (29 mi) long channel which, during flood periods, takes part of the Red River's flow around the city of Winnipeg, Manitoba to the east and discharges it back into the Red River below the dam at Lockport. It can carry floodwater at a rate of up to 140,000 cubic feet per second (4,000 m3/s), expanded in the 2000s from its original channel capacity of 90,000 cubic feet per second (2,500 m3/s).
The Red River flood of 1997 was a major flood that occurred in April and May 1997 along the Red River of the North in Minnesota, North Dakota, and southern Manitoba. It was the most severe flood of the river since 1826. The flood reached throughout the Red River Valley, affecting the cities of Fargo and Winnipeg, but none so greatly as Grand Forks and East Grand Forks, where floodwaters reached more than 3 miles (4.8 km) inland. They inundated virtually everything in the twin communities. Total damages for the Red River region were US$3.5 billion. The flood was the result of abundant snowfall and extreme temperatures.
The Souris River or Mouse River is a river in central North America. Approximately 435 miles (700 km) in length, it drains about 23,600 square miles (61,100 km2) in Canada and the United States.
Morris is a small town in the Pembina Valley region of Manitoba, Canada, located 51 km south of Winnipeg and 42 km north of Emerson. Morris is home to 1,885 people (2016). The town is named after Alexander Morris, the second Lieutenant Governor of Manitoba.
Lockport is a small unincorporated community in Manitoba, Canada. It is located 28 kilometres (17 mi) north of the city of Winnipeg along the Red River. The community is split between the Rural Municipalities of St. Andrews and St. Clements.
The Shellmouth Reservoir is a man-made reservoir on the Assiniboine River in Manitoba and Saskatchewan, Canada.
The Portage Diversion is a water control structure on the Assiniboine River near Portage la Prairie, Manitoba, Canada. The project was made as part of a larger attempt to prevent flooding in the Red River Valley. The Portage Diversion consists of two separate gates which divert some of the flow of water in the Assiniboine River to a 29 km long diversion channel that empties into Lake Manitoba near Delta Beach. This helps prevent flooding on the Assiniboine down river from the diversion, including in Winnipeg, where the Assiniboine River meets the Red River.
Osborne Stadium was a multi-sport outdoor stadium in Winnipeg, Manitoba, Canada. It operated from 1932 until 1956, and hosted Canadian football home games for the Winnipeg Blue Bombers and baseball games in the Mandak League. The stadium was also home to local high school football, soccer, baseball and softball games.
Winnipeg lies at the bottom of the Red River Valley, a low-lying flood plain with an extremely flat topography. This valley was formed by the ancient glacial Lake Agassiz which has rich deposits of black soil. Winnipeg is on the eastern edge of the Canadian Prairies in Western Canada; it is known as the 'Gateway to the West'. It is relatively close to many large Canadian Shield lakes and parks, as well as Lake Winnipeg. Winnipeg is bordered by tallgrass prairie to the west and south and the aspen parkland to the northeast.
The history of flooding in Canada includes floods caused by snowmelt runoff or freshet flooding, storm-rainfall and "flash flooding", ice jams during ice formation and spring break-up, natural dams, coastal flooding on ocean or lake coasts from storm surges, hurricanes and tsunamis. Urban flooding can be caused by stormwater runoff, riverine flooding and structural failure when engineered flood management structures, including dams and levees, prove inadequate to manage the quantities and force of flood waters. Floods can also occur when groundwater levels rise entering buildings cracks in foundation, floors and basements. Flooding is part of the natural environmental process. Flooding along large river systems is more frequent in spring where peak flows are often governed by runoff volume due to rainfall and snowmelt, but can take place in summer with flash floods in urban systems that respond to short-duration, heavy rainfall. Flooding due to hurricanes, or downgraded severe storms, is a concern from August to October when tropical storms can affect Eastern North America. Flood events have had a significant effect on various regions of the country. Flooding is the costliest natural disaster for Canadians. Most home insurance claims in Canada deal with water damage due to sewer back-up, not fire.

The history of Winnipeg comprises its initial population of Aboriginal peoples through its settlement by Europeans to the present day. The first forts were built on the future site of Winnipeg in the 1700s, followed by the Selkirk Settlement in 1812. Winnipeg was incorporated as a city in 1873 and experienced dramatic growth in the late 19th and early 20th centuries. Following the end of World War I, the city's importance as a commercial centre in Western Canada began to wane. Winnipeg and its suburbs experienced significant population growth after 1945, and the current City of Winnipeg was created by the unicity amalgamation in 1972.
The 2009 Red River flood along the Red River of the North in North Dakota and Minnesota in the United States and Manitoba in Canada brought record flood levels to the Fargo-Moorhead area. The flood was a result of saturated and frozen ground, spring snowmelt exacerbated by additional rain and snow storms, and virtually flat terrain. Communities along the Red River prepared for more than a week as the U.S. National Weather Service continuously updated the predictions for the city of Fargo, North Dakota, with an increasingly higher projected river crest. Originally predicted to reach a level of near 43 feet (13 m) at Fargo by March 29, the river in fact crested at 40.84 feet (12.45 m) at 12:15 a.m. March 28, and started a slow decline. The river continued to rise to the north as the crest moved downstream.
The Red River floods refer to the various flooding events in recent history of the Red River of the North, which forms the border between North Dakota and Minnesota and flows north, into Manitoba.

Major floods along the Mississippi River in April and May 2011 were among the largest and most damaging recorded along the U.S. waterway in the past century, comparable in extent to the Great Mississippi Flood of 1927 and Great Flood of 1993. In April 2011, two large storm systems deposited record levels of rainfall on the Mississippi River drainage basin. When that additional water combined with the springtime snowmelt, the river and many of its tributaries began to swell to record levels by the beginning of May. Flooding occurred in Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
The Fargo-Moorhead (FM) Area Diversion project, officially known as the Fargo-Moorhead Metropolitan Area Diversion Flood Risk Management Project, is a large, regional flood control infrastructure project on the Red River of the North, which forms the border between North Dakota and Minnesota and flows north to Lake Winnipeg in Manitoba, Canada.
