The Lochmere Dam is a hydroelectric facility located in Belmont, New Hampshire, at the outlet of Silver Lake. The dam is owned by the State of New Hampshire and operated by Eagle Creek Renewable Energy. The dam was built in 1986 and has four submersible turbine/generator units that produce about 4.1 million kilowatt-hours of clean energy per year. The dam also controls the downstream flows of the Winnipesaukee River. The area near the dam is part of the Lochmere Archaeological District, which contains evidence of prehistoric cultures dating back to the Middle Archaic period.
