History

It is believed Henry Kelsey was the first European to see the lake, in 1690. He adopted the Cree language name for the lake: wīnipēk (ᐐᓂᐯᐠ), meaning "muddy waters". La Vérendrye referred to the lake as Ouinipigon when he built the first forts in the area in the 1730s. Later, the Red River Colony to its south took the lake's name for Winnipeg, the capital of Manitoba.

Lake Winnipeg lies along one of the oldest trading routes in North America to have flown the British flag. For several centuries, furs were traded along this route between York Factory on Hudson Bay (which was the long-time headquarters for the Hudson's Bay Company) over Lake Winnipeg and the Red River Trails to the confluence of the Minnesota and Mississippi Rivers at Saint Paul, Minnesota. This was a strategic trading route for the First British Empire. With the establishment of the Second British Empire after Britain's loss of the Thirteen Colonies, a significant increase in trade occurred over Lake Winnipeg between Rupert's Land and the United States.

In 2016 the Indigenous place name Weenipagamiksaguygun was approved by the Geographical Names Board of Canada. It is an Anishinaabe name for the lake as used by the Poplar River First Nation.
