The Untere Grumbacher Teich , also just called Grumbacher Teich , is an artificial pond created before 1673 and about 2 hectares in size in the Harz Mountains . It lies between Hahnenklee and Wildemann in the Lower Saxony district of Goslar .
The pond is one of the Upper Harz ponds . In its catchment area are the Kranicher Ponds , the Kuttelbacher Pond , the Auerhahnteich , the Upper and Middle Grumbacher Pond and the Upper and Lower Flößteich, nine other ponds of the Upper Harz water shelf .
Geographical location
The Lower Grumbacher Pond lies within the Upper Harz in the Harz Nature Park . It is located between Hahnenklee (to Goslar ) in the northeast and Wildemann (to Clausthal-Zellerfeld ) in the southwest. It is traversed by the Grumbach , a right tributary of the Innerste, which is still fed by the Kuttelbach above the pond . It is also fed by the streams from the Great and Small Dirt Valley .
At the lower Grumbacher pond there is a refuge with the stamp point 113 “Grumbacher Teich” of the Harz hiking pin .
Data
The pond is about 2 hectares . Its catchment area is quite large at 7.92 km² for an Upper Harz pond, resulting in a high flow. The storage volume is 82,000 m³. The dam is 7.5 m high and almost 60 m long after at least one elevation.
History and rafting
The pond was created before 1673. It not only served to supply the pits below with power, but also played an important role in rafting or drifting in the Grumbach as far as Wildemann. The logs, cut into lengths of one to two meters, were led around the pond to the south through a raft ditch branching off from the Grumbach above the pond and slipped into the creek via the Gefluder in today's Grumbach waterfall . In order to wash the wood further down the valley, small tidal waves were released from the Lower Grumbach Pond , which carried the logs deep into the core.
