, a water basin formerly intended to provide leeway during low-water periods, in order to allow the continuous functioning of industrial companies, which used the hydraulic power of the river. Due to its regular flow and its significant variation, it was the scene of various industrial activities, particularly in Sherbrooke and Magog, in the 19th and 20th century. Today, its banks are mainly occupied by private residences, by linear parks, or by a few areas still wooded, industrial activities having almost all disappeared.
