Lower Merino Pond Dam

About Lower Merino Pond Dam

The primary purpose of Lower Merino Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Town Of Dudley (local government). It impounds the Unnamed Tributary Of French River near Dudley.

The dam stands 24 feet tall and stretches 340 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 40 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1850, 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. 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 11/02/2023.
