Mendums Pond Dam Repair Project
The New Hampshire Department of Environmental Services’ Dam Bureau  is planning to repair Mendums Pond Dam, and will be drawing down the level of Mendums Pond for the repair starting in September 2015.  Mendums Pond Dam is located in Nottingham, New Hampshire, but most of the pond is located in Barrington.  The dam is approximately 31 feet high and averages about 36 feet wide and 440 feet long. The dam is an earthen embankment placed between upstream and downstream dry stone masonry walls.  The dam was originally constructed in 1840 and acquired by the State in 1955.  It is one of the highest laid stone and earthen gravity dams in New Hampshire. The dam is classified as a High Hazard Dam because its failure would flood houses in Nottingham and Lee and overtop roadways downstream, including U.S. Route 4.
