The Rivière Dumoine ( English Dumoine River ) is a left tributary of the Ottawa River in western Québec in Canada .

It has its origin in the small lake Lac Machin near the Réserve faunique La Vérendrye . The river flows almost entirely south through the Canadian Shield , before flowing into the Ottawa River west of Rapides-des-Joachims .

The Rivière Dumoine has a length of 129 km and drains a catchment area of 5380 km².

The Rivière Dumoine is known as a white water river , which is great for canoeing and fishing. The area around the river is still quite original. There are a few forestry trails that cross the river. There are also several cottages between kilometers 20 and 30 .

Together with the neighboring rivers Rivière Noire and Rivière Coulonge, the river forms a grouping of white water rivers in the catchment area of ​​the Ottawa River.

The name of the river is derived from the French family Le Moynes .

Almost along its entire length, the Rivière Dumoine forms the border between the two regional counties of Pontiac and Témiscamingue .

history

The Algonquins called the Rivière Dumoine Cakawitopikak Sipi and Ekonakwasi Sipi , which means "river of alder " and is probably derived from the alder trees lining the river . A map from 1755 by Jacques-Nicolas Bellin uses the name Acounagousin .

On May 14, 2008, the Ministère du Développement Durable, de l'Environnement et des Parcs announced that 1,445 km² of the catchment area of ​​the Rivière Dumoine will be placed under protection. No industrial activities are allowed in this temporary reserve, which encompasses almost a third of the catchment area and the entire length of the river.

Paddling on the Rivière Dumoine

Paddling on the Rivière Dumoine is eventful and rewarded with a multitude of navigable rapids and its strong current. Canoe tours usually start at Lac Dumoine (100 km, about 5-7 days), Lac Laforge (75 km, 4 days) or Lac Benoit (60 km, about 3-4 days). The starting points can be reached by seaplane or on forestry roads.

The rapids vary from easy to non-navigable waterfalls. Starting from Lac Dumoine, the following rapids are noteworthy:

  • km 64, "Fish Portage" (also "Triple Play") - 3 groups of waterfalls ( Class 1 and 2)
  • km 58, "Canoe Eater" - an interesting technical class 2 boulder run
  • km 55, "Log Jam"
  • km 54, "Little Steel"
  • km 44, "Big Steel" - Class 3 to 2
  • km 23, "Grande Chute" - impressive waterfall (not accessible by canoe), followed by a class 1 rapids
  • km 17, "Red Pine" - a series of rapids from Class 1 to 3
  • km 13, "Examination"

The section between Lac Benoit and Little Steel Falls (kilometers 60-50) is particularly recommended, as there are several Class 2-3 rapids, typical of rivers that cross the Canadian Shield.
