About Clendaniel Pond Dam
The primary purpose of Clendaniel Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Joseph Warnell (private). It impounds the Hudson Mill near South Shores.
The dam stands 10 feet tall and stretches 445 feet across, creates a reservoir covering 23 acres, has a maximum storage capacity of 330 acre-feet, and collects water from a drainage area of 8 square miles. Completed in 1810, the structure is one of the older dams in the region, with over a century and a half of service.
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.
