Les Cèdres generating station

Les Cèdres generating station was built in 1913 and 1914. An embankment dike was also built upstream of the powerhouse to create a headrace canal that would direct water from the Fleuve Saint-Laurent into the powerhouse.

A number of studies and inspections of this dike conducted by Hydro-Québec show water infiltration and seepage from the headrace canal. As a result, to ensure the long-term operability of the facilities, Hydro-Québec must repair the fill of the embankment dike of the Les Cèdres headrace canal.

The purpose of this project is to improve the watertightness and stability of the dike and to minimize the risk of erosion of its foundation.

Hydro-Québec wants to reassure the public: the dyke at Les Cèdres generating station is safe, and the repair project aims to ensure that it remains safe for a long time. We want to carry out work to ensure its durability for decades to come. If you have any questions about the project, we invite you to contact us at 1 877 653-1139.
