This concrete dam, with a height of 18 feet and a length of 260 feet, primarily serves a hydroelectric purpose, contributing to the local energy supply and water management. The dam is state-regulated by the NHDES Dam Bureau and has a low hazard potential, with a very high risk assessment rating.
Despite its age, the Ashuelot Paper Mill Dam has not been rated for its condition, but it undergoes regular inspections every six years to ensure its stability and safety. The dam's controlled spillway, with a width of 79 feet, helps manage water flow during periods of high discharge, while the dam's storage capacity of 59 acre-feet provides essential water resources for the surrounding area. With its historical significance and ongoing role in water resource management, the Ashuelot Paper Mill Dam remains a vital structure for both the local community and climate enthusiasts.
