オスターオーデの湖・トップ20

One of six ponds in a cascade in the Grumbach valley as well as various moats, which were used to transport the precious water. All of these facilities were built from 1680 to supply the water wheels of the mines around Hahnenklee-Bockswiese. They are part of the cultural monument "Oberharzer Wasserregal" and since 2010 also a UNESCO World Heritage Site.🌊💙🌊

The Middle Grumbacher Pond is one of many idyllic ponds in the Upper Harz water shelf and the enchanted-looking paths here. If you want to enjoy the idyll in peace, it's better to hike here outside of weekends, public holidays and holiday periods, because the Liebesbankweg and the pond cascades are now so popular that sometimes there's almost too much going on. Or you start running when the weather isn't so great, then it's quieter :)

Here you can see the idyllic Middle Grumbacher Pond, beautifully located and great paths on the Liebesbankweg

The Oderteich, built between 1715 and 1722, is the oldest dam in Germany

The Mittlerer Grumbacher Teich is a former mining pond in the Upper Harz surrounded by forest on three sides. It is located southwest of the Bocksberg and east of the town of Bockswiese. The man-made body of water was originally called the “Herzog-August-Teich” and served as a water and energy storage facility for the ore mines and smelting operations of the Bockswieser Zug. The pond dam was built in the summer of 1675 by just 70 miners in just 10 weeks. This reservoir was subsequently raised and partially redesigned using a new pond construction method. In 1827 the dam at the Middle Grumbacher Pond almost burst. On the airside embankment, a section about 20 meters long slipped, leaving less than half a meter of the top of the dam standing. A hastily organized large-scale rescue operation was able to prevent the impending breach of the pond dam at the last moment. The impending catastrophe, which would have flooded and washed away the two raft ponds down the valley and large parts of the town of Bockswiese, did not occur and the pond, which is extremely important for the operation of the ore mines and smelting works, could be completely repaired without emptying it.

The Grumbacher ponds once created to supply water to the shafts in Bockswiese are now cultural monuments.

Intelligent people came up with this system of horizontal water equalization between the Hirschler pond and ponds in the connection of the Hutthaler Graben 250 years ago. An interesting example of industrial culture in the Harz mining industry in the 18th century.

The Huttaler Widerwaage is a water system between the Hirschler pond, the dam ditch, the Jägersbleeker pond and some other moats. It should ensure a sufficiently strong flow of water into the upper area of the Hirschler pond (i.e. in the first case of the Burgstätter Zug) to ensure the energy supply of the ore-rich pit Caroline.
