Hydrography

Lake Winnipeg has the largest watershed of any lake in Canada, receiving water from four provinces (Alberta, Saskatchewan, Ontario and Manitoba) and four U.S. states: (North Dakota and Minnesota via tributaries of the Red River, South Dakota via rivers draining into Lake Traverse, and Montana via tributaries of the Oldman River). The lake's watershed measures about 982,900 square kilometres (379,500 sq mi).

Lake Winnipeg drains northward into the Nelson River at an average annual rate of 2,066 cubic metres per second (72,960 cu ft/s) and forms part of the Hudson Bay watershed, which is one of the largest drainage basins in the world. This watershed area was known as Rupert's Land when the Hudson's Bay Company was chartered in 1670.
