The Kokish River Hydroelectric Project is a 45 MW run-of-river facility 15 km east of Port McNeill, on the north of Vancouver Island, B.C. Every step during the development process took into consideration the diversity of fish habitats in Kokish River. The project has unique and innovative details throughout the diversion reach designed to cater to this sensitive environment, and in particular the presence of steelhead trout and salmon. It has one of the largest capacity Coanda screen intakes in the world, together with one of the smallest Obermeyer crest gates in the world, a wrap-around vertical slot fish ladder, and a tailrace fish screen.
As the lead design engineer, Knight Piésold worked closely with the owner, Kwagis Power Limited Partnership, and the EPC Contractor, Peter Kiewit Infrastructure, to develop innovative and cost-effective solutions that more than met the stringent fisheries permitting requirements. The Knight Piésold team was involved throughout the project’s development.
