Importance of these rivers to the Pekuakamiulnuatsh
For the Pekuakamiulnuatsh, these rivers were also very important for establishing seasonal camps and for hunting moose. Before flowing into Lac-Saint-Jean, the two rivers join and represent an important point for the ascent and reproduction of the ouananiche.
However these rivers remain less important than the Péribonka and Ashuapmushuan and the more one goes into the interior of the territory, the less navigable they become. However, at the level of Lake Framboise, along the Mistassini River, an important stretch was identified in 1977, allowing one to believe in a significant route between the Péribonka River and the basin of the Ashuapmushuan River. Maybe even a route connecting the North-Coast with James Bay, a route parallel with the fur route but located advantageously in the depth of the territories.
