Flowing towards North, this river of about has its source in the
Ouiatchouan Lake, the
Bouchette Lake and
Lac des Commissaires. The Ouiatchouan River receives its water directly from the
Lac des Commissaires, which flows into the
Bouchette Lake. This last lake flows through a small channel in
Ouiatchouan Lake. The mouth of
Ouiatchouan Lake flows north-west to the bottom of a bay ( deep) in the Ouiatchouan River, in range VI, of Canton Dublon, from
Lac-Bouchette; then this river crosses range IV flowing north. Then, the river crosses ranges III, II and I of the Canton of Dablon of the municipality of
Saint-François-de-Sales; in range I, it receives water from Martin stream on the west side. The river continues its course to the north in the Canton of Charlevoix where it receives on the east side the waters of the Petite Rivière de la Savane. The latter flows in ranges II and I of the Dablon township; its mouth crosses the Ouiatchane river in range VII of the township of Charlevoix. A little further, the Ouiatchane river receives on the west side the waters of the Little Ballantyne river at range VI, where the river branches off to the East. The waters then cross several rapids of row VI: rapids of the islet, rapids Ballantyne and rapids of the Devil. In Chambord, the river crosses ranges V, IV, III, II and I; the waters then cross several obstacles: pine rapid (range IV), Grands Rapides (range II) and the Ouiatchouan waterfall (range II at Val Jalbert). At the end of its course, the river generates majestic falls in the heritage village of Val Jalbert, then the waters flow into a cove south of
lac Saint-Jean. The Ouiatchouan River flows for north to reach
Lac Saint-Jean, northwest of the intersection of
route 155 and
route 169. The Ouiatchouan river flows mainly in wooded areas, except the last two kilometers of its route which are agricultural in nature. == Harnessing project ==
