As of 2018, the Sterling Lake System, operated by SUEZ North America (formerly United Water), supplies drinking water from Sterling Lake to about 225 people.[4]
History
The Sterling Lake area is rich in magnetite deposits. Since before the American Revolution, this area was an important source of iron ore for the colonies. Ore was discovered at the site of the old Sterling Mine in 1750, on the south shore of the lake.[5] This led to the establishment of what would become known as the Sterling Iron Works. Another mine, called the Lake Mine, ran underneath Sterling Lake for some 3,800 feet at a depth of about 900 feet.[6] The mines were finally closed in 1921. The underground workings of both these mines are now flooded.[5]
