<Tr> <Th> Basin </Th> <Td> 23,600 sq mi (61,124 km) </Td> </Tr> <Tr> <Td_colspan="2"> The Red River drainage basin, with the Souris River highlighted </Td> </Tr> <P> The Souris River (French: rivière Souris) or Mouse River (as it is alternatively known in the U.S., a direct translation from its French name) is a river in central North America . It is about 700 km (435 mi) in length and drains about 23,600 square miles (61,100 km). It rises in the Yellow Grass Marshes north of Weyburn, Saskatchewan . It wanders south through North Dakota beyond Minot to its most southern point at the city of Velva, and then back north into Manitoba . The river passes through the communities of Melita, Hartney, Souris and Wawanesa and on to its confluence with the Assiniboine River at Treesbank, about 25 miles (40 km) south east of Brandon . The main tributaries which flow into the Souris in Manitoba are the Antler River, the Gainsborough and Plum Creeks . Much of its drainage basin is fertile silt and clay deposited by former glacial Lake Souris . </P> <P> The channel capacity of the river in Manitoba varies from about 150 cubic feet per second (4.2 m / s) near the border, to about 1,400 cubic feet per second (40 m / s) through Melita, to about 1,100 cubic feet per second (31 m / s) near Lauder and 1,700 cubic feet per second (48 m / s) near Hartney . North of Hartney the capacity increases to more than 3,000 cubic feet per second (85 m / s). The drop between the border and Hartney is only about 6 inches per mile (9.5 cm / km). </P>
