About this site
Power House is the old Mille Roches hydro-electric generating power house, which now lies underwater as one of the architectural dive sites on the St. Lawrence River. It is reached by boat from Long Sault, and it is listed among the structures along the river between Morrisburg and Kingston.
The current here is medium and visibility is good. Divers have reported eels and catfish around the structure.
