The Bois de Sioux River is a river which drains the Lake Traverse, the southernmost waters of the watershed of Hudson Bay.

It is a tributary of the Red River of the North, and forms part of the border between the U.S. states of Minnesota and North Dakota and South Dakota. The river has a length of about 48 kilometers.


The river flows starting at a dam on the United States Army Corps of Engineers at the northern end of Lake Traverse ( ⊙ 45.769276785556-96.639127166944 ) north and then flows through the Mud Lake. Below this lake the river is channeled and straightened, so that its course deviates from the historical border of the states of Minnesota and South Dakota. It flows past the White Rock before it forms together with the Otter Tail River at Wahpeton, ND and Breckenridge, MN to Red River of the North ( ⊙ 46.264129421944-96.598970581111 ).


The two largest tributaries of the Bois de Sioux are the Must Inca River, which flows into Lake Traverse and the Rabbit River, south of Breckenridge; both tributaries have their origin in Minnesota.
