About City Of Lewistown Dam
The primary purpose of City Of Lewistown 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 City Of Lewistown (local government). It impounds the Tr-middle Fabius River near Taylor.
The dam stands 25 feet tall, creates a reservoir covering 35 acres, has a maximum storage capacity of 468 acre-feet, and collects water from a drainage area of 400 square miles. Completed in 1965, 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.
