Clear Creek Dam

About Clear Creek Dam

The primary purpose of Clear Creek Dam is fish and wildlife pond. The dam creates habitat for fish and wildlife, supporting local ecosystems and potentially serving conservation goals. The dam is owned by Bureau Of Reclamation (federal). It impounds the North Fork Tieton River near Naches.

The dam stands 84 feet tall and stretches 404 feet across, creates a reservoir covering 260 acres, has a maximum storage capacity of 5,300 acre-feet, and collects water from a drainage area of 64 square miles. Completed in 1914, the structure is over a century old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 08/26/2020.

At 84 feet, this dam is taller than 97% of all dams in the United States.
