Information and products on the Souris River Basin.

The Souris River (also known as the Mouse River in the United States) originates in the Yellow Grass Marshes north of Weyburn, Saskatchewan, Canada, and flows southeast, crossing the northern boundary of North Dakota west of Sherwood, North Dakota. The Souris River then forms a loop and flows back north, entering Manitoba, Canada near Westhope, N. Dak., eventually flowing into the Assiniboine River near Brandon, Manitoba.
