About New Creek Dam No.16
The primary purpose of New Creek Dam No.16 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 Potomac Valley Cd (local government). It impounds the Thunderhill Run near Keyser.
The dam stands 102 feet tall and stretches 650 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 384 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1960, 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 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 07/31/2025.
At 102 feet, this dam is taller than 98% of all dams in the United States.
