Patterson Creek No.22

About Patterson Creek No.22

The primary purpose of Patterson Creek No.22 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 Wild Meadow Run near Burlington.

The dam stands 65 feet tall and stretches 505 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 822 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1964, the structure is well into its service life at over 50 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 09/30/2025.

At 65 feet, this dam is taller than 96% of all dams in the United States.
