About Twin-rush Creek Dam No. 3
The primary purpose of Twin-rush Creek Dam No. 3 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 Twin Rush Creek Conservancy District (local government). It impounds the Rush Creek near Rush Creek Valley.
The dam stands 74 feet tall and stretches 665 feet across, creates a reservoir covering 14 acres, has a maximum storage capacity of 1,781 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1969, 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 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 08/23/2019.
At 74 feet, this dam is taller than 97% of all dams in the United States.
