Interfor Pacific Stormwater Pond

About Interfor Pacific Stormwater Pond

The primary purpose of Interfor Pacific Stormwater Pond is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Interfor Pacific Inc. (private). It impounds the Tr - Dry Creek near Port Angeles.

The dam stands 8 feet tall and stretches 625 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 32 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2001, the structure is relatively new.

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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 09/17/2015. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
