Built in 2017, Yellow Falls is the first hydroelectric power station in Ontario.

Audet & Knight worked on the leveling of this station, located on the Mattagami River. In the underwater work field, this contract was granted by the company Pomerleau.

The project consisted of cleaning the concrete surface, taking the bathymetric measure (measurement of ocean depth through dept sounding), installing the formwork underwater, put in place the concreate, drill in the chemical anchors and also do the steel welding work.
