The Red River (French: rivière Rouge) is a Central North American river. Formed by the confluence of the Bois de Sioux and Otter Tail rivers in the United States, it flows northward through the Red River Valley and forms the border between the U.S. states of Minnesota and North Dakota before continuing on into Manitoba, Canada. The Red River flows through several major urban areas along its path including Fargo-Moorhead and Greater Grand Forks in the United States and Winnipeg in Canada. The Red is about 880 km long, falling 70 m on its trip to Lake Winnipeg where it spreads into the vast deltaic wetland known as Netley Marsh. In the United States, the Red River is sometimes called the Red River of the North which helps to distinguish it from the other Red River which is a tributary of the Mississippi River that forms part of the border between Texas and Oklahoma). In Canada, the Red has been designated as a Canadian Heritage River.

Geography
Along its course, the Red River flows across the flat, fertile flood plain of the ancient glacial Lake Agassiz. The Red River forms at Wahpeton, North Dakota and Breckenridge, Minnesota, passes through Fargo, North Dakota/Moorhead, Minnesota and Grand Forks, North Dakota/East Grand Forks, Minnesota, and then continues on to the province of Manitoba in Canada. Manitoba's capital — Winnipeg — is at the Red's confluence with the Assiniboine River. The Red then flows further north before draining into Lake Winnipeg which is part of the Hudson Bay watershed.
History
Originally part of Rupert's Land, the Red was a key river in the early settlement of Canada, a centre of the fur trade and the Métis people, and the site of the Red River Colony — the primary city of which eventually became Winnipeg, Manitoba.
The River is well known for flooding in spring due to snow runoff, and has been a topic of "paleoflood" study.[1] Although only three major floods are generally talked about since Europeans have settled in the area, in 1826, 1950 and 1997, there have been many other floods of equal size and even larger ones that can be studied due to their effects on the local landforms.[2]
1950 flood
On May 8, 1950 the Red River reached its highest level since 1861. Eight dikes protecting Winnipeg gave way and flooded much of the city, turning 600 square miles of farmland into an enormous lake. The city turned to the Canadian Army and the Red Cross for help, and nearly 70,000 people were evacuated from their homes and businesses. Four of eleven bridges in the city were destroyed, and damage was estimated at between $600 million and $1 billion.
As a result of the floods, a flood control project was started to ensure the same would never happen again. The Red River Floodway was cause for some derision at the time, as it seemed massively overbuilt and was the largest earth-moving project in the world at the time. The project was completed under-budget, and has been used for at least some flood control twenty times in the thirty-seven years from its completion to 2006. The Floodway has saved an estimated $10 billion (CAD) in flood damages.
1997 flood
In April 1997, the Red River rapidly swelled and eventually caused widespread flooding. Damages to the city of Grand Forks, North Dakota totaled $2 billion (USD) and resulted in the largest civilian evacuation in the United States since the burning of Atlanta during the Civil War.[3] In Winnipeg, the Floodway diverted most of the floodwaters around the city, although the surrounding area and some parts of the city were flooded, causing $500 million (CAD) in damage. In April 2006, another large flood caused the Gretna, Manitoba border crossing to close as the water levels rose considerably.
