On its way, its waters flow at first to southbound across the "chutes du diable" falls, then eastward, sometimes following a serpentine path. Then, the river crosses the Saint-Gérard sector (in Shawinigan) where the river veers to the south. Then the river flows in south-westerly direction along the Quebec Autoroute 55, where a drop creates waterfalls. Nearby, an observation deck was erected. Finally, the river flows into the baie de Shawinigan, where it meets the Saint-Maurice at the foot of the Shawinigan hydroelectric complex.
