About Mackville Pond

The primary purpose of Mackville Pond is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Hardwick Electric Department (local government). It impounds the Nichols Brook near Hardwick.

The dam stands 18 feet tall and stretches 80 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 208 acre-feet, and collects water from a drainage area of 10 square miles. Completed in 1900, 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 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 06/27/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
