Barrage de Portage-des-Roches

The largest water retaining structure in Kenogami Lake, this dam constitutes the source of the Chicoutimi River, whose flow is totally dependent on it.

Portage-des-Roches is located at confluence between Chicoutimi River and the eastern end of Kénogami Reservoir.

[1] This natural corridor carved out by glaciation is a depression located between the elevation of Lac Jean-Deschênes that of the southern valley of the Saguenay–Lac-Saint-Jean or Laurentides Wildlife Reserve.

As part of the main portage suite which links the Saguenay to Lac Saint-Jean, by Kenogami Lake and Chicoutimi River, Portage-des-Roches was borrowed by Father Jean Dequen in 1652.

In 1732, it was the surveyor Joseph-Laurent Normandin, who translated the Montagnais term Ashini Kushnapagan into Portage-des-Roches.
