Crane Prairie Dam

About Crane Prairie Dam

The primary purpose of Crane Prairie Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Bureau Of Reclamation (federal). It impounds the Deschutes River.

The dam stands 36 feet tall and stretches 285 feet across, creates a reservoir covering 4,940 acres, has a maximum storage capacity of 68,800 acre-feet, and collects water from a drainage area of 184 square miles. Completed in 1940, 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 05/17/2023.

At 36 feet, this dam is taller than 83% of dams nationwide.
