    The dam ditch is the longest man-made ditch in the Upper Harz. Its purpose was to divert surface water for the operation of the Upper Harz coal and steel industry from distant areas with high levels of precipitation (in particular from the Bruchberg massif and parts of the Brocken massif). It was laid out from 1732 and extended further and further east until 1827. Its original total length was about 25 km; This could be successively shortened to about 19 km through the construction of underground sections, so-called watercourses, in the years 1820 to 1861. It gets its name from the Sperberhaier Dam, which bridges a depression in the terrain.
