The Winnipeg River is a Canadian river that flows roughly northwest from Lake of the Woods in the province of Ontario to Lake Winnipeg in Manitoba. This river is long from the Norman Dam in Kenora to its mouth at Lake Winnipeg. Its watershed is in area, mainly in Canada. About of the watershed is in northern Minnesota, United States. The Winnipeg River watershed was the southeasternmost portion of the land granted in 1670 to the Hudson's Bay Company. The portion in Canada corresponds roughly to the land deeded to Canada in Treaty 3, signed in 1873 by Her Majesty's treaty commissioners and the First Nation chiefs at Northwest Angle on the Lake of the Woods. The river's name means "murky water" in Cree. This river route was used by natives for thousands of years before European contact. French and English colonists also began to use the river in order to reach First Nations for the fur trade, with trade interactions for hundreds of years. It is the only major water route between what is now Ontario and southern Manitoba that was easily navigable by canoe. The Red River route was much farther south and had a longer portage. La Vérendrye was one of the first explorers to establish fur trade forts near the First Nations camps along the river. The river section through Whiteshell Provincial Park has many petroforms near the Whiteshell River forks where the two rivers meet. These petroforms are an ancient reminder of the importance of the area for native travel, trade, ceremonies, harvesting, and settlements. Geography The Winnipeg River watershed stretches to the height of land about west of Lake Superior. Major modern communities along the banks of the Winnipeg River include Kenora, Minaki and Whitedog in Ontario; and Lac du Bonnet, Pinawa, Powerview, and Pine Falls, all in Manitoba. Whitedog is the home of the Wabaseemoong First Nation. The Sagkeeng First Nation is located near the mouth of the Winnipeg River and Pine Falls. In Ontario, dams were built on the Winnipeg River at Kenora, exiting Lake of the Woods, and at Whitedog Falls. Power from the dams have supplied Kenora and a local pulp and paper mill, while local Anishinaabe populations have been negatively impacted by consequent environmental degradation. In Manitoba, there are six hydroelectric dams: Pointe du Bois Generating Station at Pointe du Bois, Slave Falls a few kilometres downstream, Seven Sisters
