Upper Wheeler Saddle Dam

About Upper Wheeler Saddle Dam

The primary purpose of Upper Wheeler Saddle Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Wenatchee Heights Reclamation District (public utility). It impounds the Orr Creek near Malaga.

The dam stands 15 feet tall and stretches 150 feet across, creates a reservoir covering 33 acres, has a maximum storage capacity of 495 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1992, the structure is 34 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 09/22/2020.
