Frozen Lake Dam

About Frozen Lake Dam

The primary purpose of Frozen Lake Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Doi Nps (federal). It impounds the Tr-white River near Tacoma, Wa.

The dam stands 14 feet tall, and has a maximum storage capacity of 68 acre-feet. Completed in 1930, the structure is well-established, with more than 75 years of service.

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 08/09/2023.
