About Spokane Hutterian Brethren Dam

The primary purpose of Spokane Hutterian Brethren Dam 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 Spokane Hutterian Brethren (private). It impounds the Unnamed Trib - Deep Creek.

The dam stands 39 feet tall and stretches 480 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 84 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2006, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 05/08/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 39 feet, this dam is taller than 85% of dams nationwide.
