Outardes-3
Outardes-3 is a hydroelectric power station and dam on the Outardes River  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  downstream of Outardes-4. Only a  high concrete dam was needed to exploit  of hydraulic head as the dam raised up water into the existing Lake Tirebouchon. Raising the water in the lake allowed it to rise east near the actual power station  downstream. Near the eastern portion of the lake, two depressions were filled in with small dikes to withhold the higher lake level, one of which supports a concrete spillway. From the intake on the northern portion of the concrete dam, water is fed via four  penstocks towards the underground power station. Water being discharged from the power station enters a  long and  high tunnel before being returned to the river.
