The Lower Spiegeltal Pond was created by Upper Harz miners in the 17th century as part of the Upper Harz Water Regale and is one of the Upper Harz Ponds. Like all structures of the Upper Harz Water Regale, the Lower Spiegeltal Pond has been part of the UNESCO World Heritage Site of Rammelsberg Mine, Goslar Old Town, and Upper Harz Water Management since 2010.

A beautiful, well-maintained facility. Plenty of rest areas and a lovely café right by the pond.

The reservoir supplies drinking water to the cities of Braunschweig, Wolfenbüttel, and Wolfsburg. The water is piped to the Lewerberg reservoir near Liebenburg, where drinking water from the Grane Dam also arrives. From there, a pipeline leads to the Thieder Lindenberg and further to the cities of Braunschweig and Wolfsburg. The water of the Ecker River is relatively acidic, with a pH of 4.6, due to the humic acid-rich moor streams. It is also low in nutrients and therefore well suited for drinking water treatment.[3] The dam is not used for fishing, as most fish cannot tolerate the low pH.[5] Below the dam, the water is almost neutral.

The Ecker Dam (sometimes also called the Ecker Reservoir) is a dam near Bad Harzburg in the Harz Mountains, which was commissioned in 1943[1] and impounds the Ecker River and its tributaries. Operated by Harz Waterworks, the facility serves to supply drinking water, protect against flooding, increase low water levels, and generate energy.[2] Source: https://de.wikipedia.org/wiki/Eckertalsperre
