About Wolf Creek

The primary purpose of Wolf Creek is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Powder Valley Water Control District (local government). It impounds the Wolf Creek And Anthony Creek near North Powder.

The dam stands 128 feet tall and stretches 1,600 feet across, creates a reservoir covering 220 acres, has a maximum storage capacity of 12,000 acre-feet, and collects water from a drainage area of 32 square miles. Completed in 1974, the structure is well into its service life at over 50 years 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. 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 08/24/2020.

At 128 feet, this dam is taller than 98% of all dams in the United States.
