Red River of the North
The Red River (French: Rivière rouge, German: Roter Fluss, American English: Red River of the North) is a North American river. 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 the border of Minnesota and North Dakota and continuing into Manitoba, Canada. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into the Hudson Bay, which is considered part of the Arctic Ocean.
The Red River flows through several urban areas along its path, including those of Fargo-Moorhead and Grand Forks in the United States and Winnipeg in Canada. The Red is about 885 kilometres (550 mi) long, of which about 635 kilometres (395 mi) are in the United States and about 255 kilometres (158 mi) are in Canada. The river falls 70 metres (230 ft) 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, to distinguish it from the Red River that is a tributary of the Mississippi River, and that forms part of the border between Texas and Oklahoma.
Long a highway for trade, the Red has been designated as a Canadian Heritage River.
There may be records about the migration in these states:
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, at a point commonly referred to as The Forks. The Red then flows further north before draining into Lake Winnipeg which is part of the Hudson Bay watershed through the Nelson River. The mouth of the Red River forms a freshwater river delta called the Netley-Libau Marsh. The Netley Marsh is west of the Red and the Libau Marsh is east to form a 26,000 hectare wetland.
