Revelstoke Project is located in southeastern British Columbia on the Columbia River, 130 km downstream of the Mica Dam and approximately 5 km north of the City of Revelstoke. The project consists of a 175 m high concrete gravity dam in the canyon containing the power intakes, a six 460 MW units powerhouse in the river channel immediately downstream of the gravity dam, a spillway with integrated outlets on the right (west) bank of the river and a 126 m high earthfill wing dam across the right bank terrace. River diversion during construction was effected by a 557 m long single concrete lined circular tunnel, with an internal diameter of 13. 1 m, located in the right bank between the spillway and the powerhouse. The hydraulic design of the discharge facilities of this project is generally conventional and follows the established standards of U. S. Bureau of Reclamation and U. S. Army Corps of Engineers. Only those special design features and their operating experience are discussed in this paper.
