Vincentown Mill Dam

About Vincentown Mill Dam

The primary purpose of Vincentown Mill Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Township Of Southampton (local government). It impounds the South Branch Rancocas Creek near Vincentown.

The dam stands 12 feet tall and stretches 400 feet across, creates a reservoir covering 22 acres, has a maximum storage capacity of 557 acre-feet, and collects water from a drainage area of 52 square miles. Completed in 1891, the structure is over a century 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 03/26/2024.
