About Carrier Creek Structure A
The primary purpose of Carrier Creek Structure A 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 Eaton County Drain Commissioner (private). It impounds the Carrier Creek.
The dam stands 24 feet tall and stretches 800 feet across, has a maximum storage capacity of 153 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2008, 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 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 10/30/2020.
