The Knappschaftsteich (Miners’ Association Pond) was created in 1684 and directly borders the Siebenschlehen stamp mill. This pond supplied the water to power another stamp mill situated below the Siebenschlehen stamp mill. The pond includes a loam-sealed earth dam, a terrace wall, a control hut for sluicing water, and a spillway. Its construction is similar to the Lindenau stamp mill pond, which also belonged to the Siebenschlehen stamp mill. The mine obtained the process water for the stamp mill and the washing works from the 600-metre ditch leading from the Lindenau pond to the stamp mill.
