The Seton Powerhouse is a hydroelectric generating station on the Fraser River just below the confluence of the Seton River at the town of Lillooet, British Columbia, Canada. The powerhouse is fed by the Seton Canal, a 5 km diversion of the flow of the Seton River which begins at Seton Dam, just below the foot of Seton Lake to the west. The powerhouse is the last in sequence, and smallest, of the generating stations of the Bridge River Power Project, which diverts the flow of the Bridge River into Seton Lake.
