Nemsca

Nemiscau lies on a lake of the same name along the Rupert River, between Lake Mistassini and James Bay. Its Cree name is associated with fish, an important resource in these inland waters. The lake formed part of the homeland of the Nemaska Cree and a stopping place on the long water route to the coast, where the Rupert enters the sheltered waters of its bay.

The Jesuit Charles Albanel recorded reaching Lake Nemiskau on 25 June 1672, during his journey towards James Bay. French traders established a post in the district in 1684, and the Hudson's Bay Company later operated posts in the area. These establishments brought merchants into contact with Cree families whose knowledge of the river and surrounding country was essential to travel and trade.
