The New Pond , rarely Kuhschachter Pond , was a reservoir near Freiberg in Saxony . The Münzbach was dammed . The pond was an urban process water reservoir and not part of the "Electoral Stolln and Röschen Administration of Freiberg" . However, the mine water for the mountain building of the Kuhschacht Grube, later for the Ascension and the Abraham Treasure Trove, was channeled through the pond into the Kuhschacht artificial ditch via the Münzbacher Hüttengraben .
location
The new pond was located southeast of the Freiberg suburb of Neusorge in the Oberloßnitz corridor. His dam was located approx. 300 meters southeast of the Silberhof Vorwerk. The storage space extended in an arc shape for about 500 m to the southeast in the direction of the Mauckischer Vorwerk. Silberhofstrasse roughly follows its right bank. On the right bank of the pond the Alte Frauensteiner Strasse ran from Freiberg over the Lerchenhübel to the raisin house.
history
Construction and use
Under chief mining Abraham by Schoenberg in consequence of was the Thirty Years' War prostrate mining intensified. In order to guarantee the water requirements of the pits and the economy as a whole, the hut pond upstream was tensed again in 1672 . In the same year, 6,000 guilders were made available by the Freiberg City Council for land acquisition and construction costs for another pond as a municipal water reservoir. This completely new pond was finally created between 1674 and 1682. As with other hydraulic engineering systems in the region, the water was used in a variety of ways. He ensured a continuous supply of impact water for the malt mills on the Münzbach, since more and more of the water was withdrawn from them by the systems of the electoral mine water supply systems. In 1682 the Kuhschacht Grube in the Neusorge had acquired the Scheinstadt , the mill square of the desert stone mill, including the water falling from the Stockmühle into the Scheinstadt , in order to build a Poch wash there. At the same time, the union on Kuhschacht Grube had the Münzbach water that the mine was entitled to lend itself to as far as the Münzbachhütten. The mine water - the city could only dispose of the Münzbach water below the Münzbachhütten - via a water divider into the newly created Kuhschacht artificial ditch, which led behind the Stockmühle through the Münzbach valley to the Neusorge.
In the middle of the 18th century the water flow of the Münzbach had decreased so far that the Stockmüller Mehner had to convert his drive from an overshot Mühlgezeug at the Mühlgraben from Münzbach to an undershot Gezeug in the artificial moat against a contribution to the silting and covering of the Kunstgraben was approved. This triggered a protest by the Freiberg Council, which saw this as an advantage for the new owner of the Stockmühle over the municipal malt mills and at the same time criticized the silting up of the New Pond by mining. With the exception of Mehner's successor, Silbermann, from whom the Freiberg Mining Authority had withdrawn the water from the Kuhschacht artificial ditch due to his arrogance and aggressiveness towards the ditch climber, all subsequent Stockmillers used the artificial ditch to drive the mill.
After the construction of the Himmelfahrter artificial ditch branching off from the Kuhschacht artificial ditch, the desolate ditch below the New Pond was no longer able to hold the water for both pits and the stick mill without damage, so that the water of the artificial ditch was temporarily withdrawn from the mill. The widow of the smelter, Richter, applied for the shock and quarter tax for the Stockmühle to be halved, and her heirs filed a complaint against the refused transfer. The Freiberg malt millers were responsible for overseeing the New Pond, who temporarily - for a fee - commissioned Kuhschacht art and digging climbers.
Dam break
After the floodlights were opened on the evening of June 1, 1839 as a result of heavy rain at the Berthelsdorfer Hüttenteich, the water from the Münzbach and the surrounding slopes flowed into the New Pond. Early in the morning of the next day at 3 a.m., the Himmelfahrter art climber Müller , who lives in the ABC Vorwerk in Neusorge, noticed a flood of water in front of the house and suspected that the New Pond was flooding. Müller could not open the floodlight there because it was nailed up and looked for helpers to open the floodlight. At around 4 a.m. the dam of the new pond broke and a tidal wave poured through the Freiberg Münzbachtal.
After the Freiberg Malzmüller Teichmann had declared that the city would waive all claims to the water from the Neue Teich in the lawsuit pending against him, the city initially left the Teichstatt desolate and wrote it out in 1851 for reclamation. The following year, the Himmelfahrt Fundgrube bought the pond in order to use it together with Junge Hohe Birke Fundgrube as a flood sand for the Turmhofer and Junghohebirkner washers. With the commissioning of the Himmelfahrter Central Wash, the hearth flood desanding pond at Münzbach was no longer needed from 1889. In 1902, the city of Freiberg prepared a development plan for the area “Torn out pond”.
