Amelia Earhart Dam
The 928th tallest dam in the world
The Amelia Earhart Dam is an earth-fill dam spanning the Mystic River near its mouth between Somerville and Everett, Massachusetts. It was built in 1966 to regulate tidal effects and the incursion of salt water in the upstream river basin. The dam is named after the aviation pioneer Amelia Earhart whose plane disappeared in 1937. Earhart lived in nearby Medford, Massachusetts in the 1920s. There is no public access to the dam.
