About Coachlace Pond Dam

The primary purpose of Coachlace Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Tyca Real Estate Llc (private). It impounds the Counterpane Brook Tributary Of Nashua River near Clinton.

The dam stands 13 feet tall and stretches 440 feet across, creates a reservoir covering 134 acres, has a storage capacity of 201 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1846, the structure is one of the older dams in the region, with over a century and a half of service.

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. The most recent inspection on record was 08/15/2017.
