The dam standing at a height of 60 feet serves multiple purposes including hydroelectric power generation, flood risk reduction, navigation, and recreation. With a normal storage capacity of 117,080 acre-feet and a surface area of 6,838 acres, the lake provides essential water resources for the region.
Managed by the Federal Energy Regulatory Commission, Seboomook Lake is a vital hub for fish and wildlife conservation, with a spillway width of 429 feet and controlled spillway type ensuring the safety and ecological balance of the area. Despite its high hazard potential, the dam's risk assessment is very high (1), indicating the need for stringent risk management measures. The emergency action plan for the dam was last revised in December 2018, highlighting the importance of preparedness and safety protocols in the event of any unforeseen emergencies.
Seboomook Lake's scenic beauty and ecological significance make it a valuable asset for water resource and climate enthusiasts. Its role in providing clean energy, water supply, and recreational opportunities underscores the importance of sustainable dam management practices to preserve this natural wonder for future generations.
