The Mittlere Pfauenteich (also Great Peacock Pond ) on Zellbach near Clausthal-Zellerfeld in the Upper Harz ( Lower Saxony ) is a small dam in the Upper Harz water shelf and is one of the Upper Harz ponds . Like many systems in the Oberharzer Wasserregal, it is part of a cascade in the upper Zellbachtal. The lower peacock pond is at the lowest position, followed by the middle and upper peacock pond. Above that is the much larger Hirschler pond.
dam
The storage facility (storage capacity 310,000 m³), built with a dam made of earth with an outer seal made of turf, was increased at least twice and converted into the so-called "new construction" in the 18th century. It served to supply water to the mines in Clausthal, especially on the Burgstätter Gangzug. The operator of the dam, originally built by the Oberharzer Bergbau, is now Harzwasserwerke GmbH.
On the top of the dam there are two harrow houses . The harrowing device located higher and further south formed the so-called "upper case" and was previously able to take water from the damming lamella of the top 4.5 m, whereas the second harrow house controls the bottom outlet (bottom harrow). The Elisabether Graben runs over the berm of the Middle Pfauenteich from the Upper House Herzberger Teich, which is practically the extension of the dam ditch . The water from the upper falls feeds another ditch, meets the Elisabether ditch and then leads around the lower peacock pond. At the junction there is a failure that directs excess water into the lower peacock pond. In contrast, the water from the bottom harrow is only fed into the lower peacock pond. The possibility of taking water from the "Upper Fall" enabled the miners to take water from the pond at a higher level and to pass it on at a correspondingly higher level in order to be able to feed it to a higher water wheel.
At one end of the dam, an approx. 100 m long intermediate dam was built across the reservoir for a rod art , which separates a small "triangle" from the storage area. A waterwheel was located at the foot of the Middle Peacock Pond, and the water from the Jägersbleeker and Langer Pond was fed through a channel on its dam crest . The "forces" were transferred over the new dam to the Dorothea pit via the 310 m long artificial rods. After the Hirschler pond above was able to store more water, the Dorotheer Kehrrad was supplied with water directly from there and the dam was no longer needed. During this renovation, the sweeping wheel was moved close to the shaft in an underground wheel room. Around 1750 the approx. 350 m long Dorotheer Rösche was excavated to drain this cycle room .
Ecological damage
The middle peacock pond, together with the lower peacock pond adjoining it, was polluted with over 16,000 m³ of harmful neutralization sludge from the explosives production of the Tanne plant during the Second World War . This sludge was removed and disposed of in 2011 and 2012.
