, at Grandes-Piles: * Lake Gabriel, whose waters flow successively into Lac de la Bouteille and Lac à la Truite. Between the mouth of lac Gabriel and the north bay of lac à la Truite, the waters descend on ; the water then crosses this last lake over its entire length, i.e. . * the two Jean-Baptiste lakes, whose waters flow successively into Lac des Caribous, a small unidentified lake, Lac Gagnon () and Lac à la Truite ( in length including the bay to the north and 700 in width). The latter lake also receives the waters of Castor Lake on the southwest side. Between the mouth of Lac Jean-Baptiste (the highest) and the mouth of Trout Lake, the current descends on , including a course, crossing this last lake. Upper course From Lac à la Truite, the waters descend for a kilometre to empty into Lac Tavibois (length: ; altitude: ) at Grandes-Piles, located in the Tavibois area. A retention dam has been built at its mouth with automated control of the water level; this dam is located on the boundary between Grandes-Piles and Hérouxville. After this dam, the water crosses a fall to flow further southeast into Lake Léo (length: ; altitude: ) which has a small dam at its mouth. This lake flows eastwards into Tessier lake (length: ; ) that the current crosses on towards the North. The lake collects a stream (coming from the north) which drains the western slope of Le Chaudron mountain (altitude: ) which straddles the limit of Saint-Tite and Hérouxville, almost at the limit from Grandes-Piles. From the dam at the mouth of Lake Tessier, the current heads northeast over , towards Le Chaudron mountain, before turning southeast to descend on crossing Chemin des Petites-Forges, up to a stream (coming from the northeast). From there, the course of the river heads south on first by forming serpentines, then crossing the Petit lac du Castor (length: ; altitude: ) and very narrow), to the dam located at its mouth, south of the lake. About thirty chalets surround the Petit lac du Castor. From this last dam, the current descends towards the south-east, crosses towards the north a small narrow lake (length: ; altitude: ) to the small dam at its mouth. From there, the current flows on eastward, forming two hooks, one north, the other south, to the discharge (coming from the north) of a lake. Then the current goes to , first over south to a stream (coming from the south), then on eastward crossing Lake Ayotte (length: ; altitude: ) whose dam is located in the camp Val Notre-Dame, then on south-east to the mouth of Ruille stream (coming from the south). Lower course From there, the river heads northeast on where it crosses the

boundary. Then the river crosses another in the zone to cut the route 159. And the mouth of the Mékinac du Sud river is further away, as the water flows into the North Mékinac River. On most of its route, approximately (measured by water) from the mouth of lac à la Truite (or from lac Jean-Baptiste), the river flows mainly in a forest environment. In short, the river runs in Grandes-Piles, in Hérouxville because of the streamers and in Saint-Tite.
