Waneta Dam Expansion Project


The Waneta Dam Expansion project is one of Chinook's current challenges. This is a near billion dollar project that will see the addition of a second powerhouse downstream from the Waneta Dam on the Pend d'Oreille River south of Trail, BC. This expansion will share the existing dam's hydraulic head and generate power from the flow that would otherwise be spilled. For further details on this project and to download the weekly project update please see the Columbia Power website: www.columbiapower.org

Pictured below in the tunnel is a twenty foot long by thirty foot wide rolling scaffold used for concrete finishing in this two hundred meter long tunnel on a 17% slope. These tunnels are being designed to convey water from the Waneta forebay into a two-unit powerhouse (to be built) between the Waneta Dam and Highway 22A.
