 The Chute d'Aval (Downstream Falls) was from the Sainte-Marguerite River mouth, and the Chute d'Amont (Upstream Falls) was from its mouth.The Clarke brothers built a paper mill from the mouth of the river between 1903 and 1908, and in 1908 inaugurated the first hydroelectric plant to supply electricity to the mill and to the nearby Clarke City.They also built a railway to link the paper mill to Pointe-Noire, where they built a wharf.
