The Red River begins at the confluence of the Bois de Sioux and Otter Tail rivers, on the border of Wahpeton, North Dakota and Breckenridge, Minnesota. Downstream, it is bordered by the twin cities of Fargo, North Dakota – Moorhead, Minnesota, and Grand Forks, North Dakota – East Grand Forks, Minnesota. It crosses the Canada–United States border just before reaching the town of Emerson, Manitoba. Manitoba's capital, Winnipeg, is at the Red's confluence with the Assiniboine River, at a point called The Forks. Together with the Assiniboine, the Red River fully encloses the endorheic basin of Devils' Lake and Stump Lake.
