Assiniboine River

The Assiniboine River is a river 1070 km long that runs through the prairies of western Canada. It is a typical meandering river with a single main channel embanked within a flat, shallow valley. It flows south-east from Saskatchewan to "the Forks" in Winnipeg, Manitoba into the Red River of the North. Some of the flow is diverted into Lake Manitoba at Portage la Prairie. In 1967, a dam was built in Shellmouth, Manitoba that controls the river's flow. There are three stations placed down the river that have been taking measurements since 1913.
Tributaries include the Souris River which joins it near Brandon, Manitoba.
