About Patterson Creek No. 41 Dam

The primary purpose of Patterson Creek No. 41 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 Potomac Valley Cd (local government). It impounds the North Fork near Burlington.

The dam stands 91 feet tall and stretches 1,070 feet across, creates a reservoir covering 26 acres, has a maximum storage capacity of 7,960 acre-feet, and collects water from a drainage area of 27 square miles. Completed in 1969, 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 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 91 feet, this dam is taller than 98% of all dams in the United States.
