The dam serves as a crucial water supply source, with a maximum storage capacity of 3996 acre-feet and a normal storage level of 1665 acre-feet. The reservoir covers a surface area of 333 acres and has a drainage area of 21 square miles, with a spillway width of 69 feet for uncontrolled discharge.
Maintained by the NHDES Dam Bureau, Bellamy Reservoir Dam is subject to regular state regulation, inspection, and enforcement to ensure its structural integrity and safety. The dam has been assessed as being in satisfactory condition, with a high hazard potential due to its location on the Bellamy River. In the event of an emergency, the dam has an established Emergency Action Plan (EAP) to guide response and mitigation efforts, although the last revision date was in 2009.
Despite its moderate risk assessment, Bellamy Reservoir Dam remains a significant component of the local water infrastructure, providing essential water supply services to the surrounding community. As climate change continues to impact water resources and infrastructure, ongoing monitoring and maintenance of the dam will be crucial to safeguarding its functionality and resilience in the face of evolving environmental challenges.
