General Presentation

25 km West of Seven Islands, the SM-1 generating station is situated on the first set of falls on the Sainte-Marguerite River. The facility is located on the site of an abandoned wood mill originally used for pulp and paper manufacture.

Gulf Pulp and Paper, the mill owners, ceased operations in 1968. The site lay idle for 20 years before being acquired by Hydromega in 1989. At the base of the existing dam, an entirely new generating station was constructed between April 1992 and December 1993.
