An engineering marvel dating from 1536 to 1866, the Upper Harz Water Management System is considered one of the Harz Mountains' greatest attractions. It encompasses all the structures built to store water and transport it to mines, some of which are located far away. It is one of the largest and most significant historical water management systems in the world of mining. The Upper Harz Water Management System includes numerous reservoirs, kilometers of water channels, and underground waterways.

The "Grüner Hirsch" (Green Stag) silver mine, belonging to the Burgstätter mining district and once located about 400 meters west of the Mittlerer Pfauenteich (Middle Peacock Pond), began operations in August 1645. It was one of the few, not particularly productive, ore mines in this mining area. This mine would probably have long since been forgotten if the pond, built around the same time and named after it, had not soon played a crucial role in mining near Clausthal. The exact date of the pond's construction has not been recorded, but it likely occurred at the same time as work began at the "Grüner Hirsch," or at least before 1660. In any case, a comprehensive document from 1661, which has survived to the present day, already lists the "Grüner Hirsch Pond" as part of the water supply for the Burgstätter main drainage system.

The Bärenbrucher Teich (Bärenbruch Pond) is a reservoir near Buntenbock belonging to the Upper Harz Water Management System, and its history can be traced back to the 17th century. Today, the Bärenbrucher Teich operates as an overflow reservoir, meaning that the inflowing water flows over the spillway into the Ziegenberger Teich (Ziegenberg Pond). The stamp box is located in the shelter at the dam. Source: https://www.harzer-wandernadel.de/stempelstellen/uebersichtskarte/stempelstelle-137-baerenbrucher-teich/
