Greenburn Reservoir
Greenburn Reservoir (aka Greenburn Tarn) on Greenburn Beck, is located in Little Langdale in Cumbria. It is a man-made reservoir, unlike other tarns in the area, which were formed by glacial erosion. It was built in the 19th century to supply water to the workings of Greenburn Copper Mine. The dam forms most of the south-east side of the reservoir, which has with spillways at the north and south ends. The reservoir first appears on the 1891 six inch map[1], but likely by the mid-19th century, at the peak of activity for the mine .
