Outardes-3 is a hydroelectric power station and dam on the Outardes River 55 km (34.2 mi) northwest of Baie-Comeau, Quebec, Canada. The power station was commissioned in 1969 and is run-of-the-river.Outardes-3 was built in conjunction with the Manicouagan-Outardes project and is located 13 mi (20.9 km) downstream of Outardes-4. Only a 250 ft (76.2 m) high concrete dam was needed to exploit 478 ft (145.7 m) of hydraulic head as the dam raised up water into the existing Lake Tirebouchon.
