This concrete dam-gravity type has a height of 53 metres (174 ft) and a length 442 metres (1,450 ft). Its retaining capacity is 6 million cubic meters of water at the outlet of Tourouvre lake. The lake is formed by a widening of the Saint-Maurice River because the dam receives water from the Trenche River.
