About Poepsel Farm Lake Dam
The primary purpose of Poepsel Farm Lake 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 Herbert Struckhoff (private). It impounds the Tr Bigelow Creek near Augusta.
The dam stands 32 feet tall, creates a reservoir covering 6 acres, has a maximum storage capacity of 103 acre-feet, and collects water from a drainage area of 65 square miles. Completed in 1972, 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.
At 32 feet, this dam is taller than 76% of dams nationwide.
