Its construction was completed in 1950. This power station was put into service immediately. It is the central sixth to block the river from its mouth. With its 302 megawatts (405,000 hp), it is the most powerful.^{[clarification needed]}^{[citation needed]} Hydro-Québec acquired La Trenche power from the Shawinigan Water & Power Company.

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.
