About Stony Creek Dam #9

The primary purpose of Stony Creek Dam #9 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 Lord Fairfax Soil And Water Conservation District (local government). It impounds the Stony Creek.

The dam stands 80 feet tall and stretches 960 feet across, creates a reservoir covering 44 acres, has a maximum storage capacity of 3,417 acre-feet, and collects water from a drainage area of 7 square miles. Completed in 1971, 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 12/08/2021.

At 80 feet, this dam is taller than 97% of all dams in the United States.
