The Deuxième bras des Iroquois (English: Second Arm of the Iroquois) is a tributary of the Iroquois River, flowing in the unorganized territory of Lac-Ashuapmushuan and municipality of Sainte-Hedwidge, in the Le Domaine-du-Roy Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province from Quebec, to Canada. The upper part of the valley of the "Deuxième bras des Iroquois" is served by forest roads; the lower part, by the path of 9th row. Forestry is the main economic activity in this forest valley; recreotourism activities, second. The surface of the Deuxième bras des Iroquois is usually frozen from the beginning of December to the end of March, except for the rapids; however, traffic on the ice is generally safe from mid-December to mid-March. Geography The Deuxième bras des Iroquois originates from Desmarais Lake (length: ; altitude: ) in Sainte-Hedwidge. This lake has two outlets; the other flowing towards the hydrographic slope of Lac aux Iroquois. The northern mouth of Desmarais Lake is located at: north-west of Lac aux Iroquois which turns out to be the head lake of Rivière aux Iroquois; south-west of the village center of Sainte-Hedwidge; south of the mouth of the Iroquois river. From the north mouth of Lac Desmarais, the Deuxième bras des Iroquois flows over with a drop of , according to the following segments: towards the northwest by collecting the discharge (coming from the south) of lakes Calme and Sacré-Coeur, to the discharge (coming from the east) of lakes Jeannine and Jerry; generally towards the north by crossing two zones of marshes, by collecting the discharge (coming from the west) of two lakes including Lac Chanceux, and by forming a loop towards the northwest to bypass a mountain and collect the outlet (coming from the northwest) from Lac Poélon and Indien, up to the outlet (coming from the southeast) from Lac Rat Musique. Note: At the end of this segment, the course of the river leaves the zec de la Lièvre; towards the northwest by entering the unorganized territory of ac-Ashuapmushuan, passing between two mountains, collecting the discharge (coming from the southwest) of the Lake at Mouche, collecting the discharge (coming from the west) from Lac de la Chute, to a bend in the river; south-east, re-entering Sainte-Hedwidge, up to a bend in the river; first towards the northeast, then towards the north while winding in the second half of the segment,
