The River Rivière Coulonge ( English Coulonge River ) is a largely untamed river in the west of the Canadian province of Québec .
It has a length of 241 km, a catchment area of 5232 km². It runs from its source at Lac au Barrage (in the Réserve faunique La Vérendrye ) mainly in a south-easterly direction to the Ottawa River , into which it flows at Fort-Coulonge . Over this distance, the river overcomes a gradient of 260 m, 48 m of which are accounted for by the Chutes Coulonge (also Grandes Chutes ) waterfalls at ( ⊙ ), about 15 km upstream from the confluence with the Ottawa River.
As a white water river popular with canoe enthusiasts , it is often mentioned along with the neighboring rivers Rivière Dumoine and Rivière Noire . All three rivers are in the same catchment area and have similar white water properties. All three flow into the Ottawa River within a distance of 65 miles.
history
The Rivière Coulonge river was named after Nicholas d'Ailleboust, Sieur de Coulonge. In the winter of 1694-95 he founded a trading post at the mouth of the river. This was the first permanent European settlement in the Pontiac region of western Québec.
The river was used as a waterway by the Native Americans . Later it was used by Coureurs des bois for their fur trade. In 1835, the Scottish wood baron George Bryson acquired rights of use over large areas of forest around the Grandes Chutes.
In 1994 a hydroelectric power station with a dam was built above the Grandes Chutes. This leaves only the Rivière Dumoine as the last major free-flowing tributary of the Ottawa River.
