Skookumchuck Dam
The 490th tallest dam in the world
Skookumchuck Dam is an earthen dam located on the Skookumchuck River in Washington state, east of Bucoda and Tono. Owned by TransAlta since 2004, the embankment was built in 1970 to supply water for the Centralia Power Plant located in Hanaford Valley. Various proposals have been introduced to use the dam as a flood-mitigation tool or have the levee removed to improve river flow and the ecosystem. The Centralia Power Plant, also owned by TransAlta was decommissioned in 2025; water rights to the dam are planned to be given to the city of Centralia.
