Completed in 1860, this dam serves primarily for recreational purposes, providing a storage capacity of 1400 acre-feet and covering a surface area of 205 acres. It spans 130 feet in length and stands at a height of 17 feet, with a spillway width of 60 feet for uncontrolled discharge.
Despite its historical significance, Sunset Lake Dam currently carries a high hazard potential and has been rated as being in poor condition. The last inspection in May 2020 highlighted the need for maintenance and repairs to ensure the safety of the surrounding area. The dam is regulated and inspected by the NHDES Dam Bureau, with enforcement and permitting processes overseen by the state of New Hampshire.
Climate and water resource enthusiasts will find Sunset Lake Dam to be a compelling case study in dam management and risk assessment. As it faces moderate risks and a history dating back to the 19th century, the dam presents challenges and opportunities for sustainable water management practices in the face of changing environmental conditions. With its location on the Suncook River and its association with recreation, the dam serves as a focal point for balancing human activities with the preservation of natural resources.
