About Arnold Dam
The primary purpose of Arnold Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Heather Linscott & Robin Avery (private). It impounds the Pecks Brook near Adams.
The dam stands 21 feet tall and stretches 150 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 9 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1954, the structure is well into its service life at over 50 years old.
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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 11/18/2015. That was over 10 years ago.
