The Rotvorwerksteich , rarely Männigsteich , was an artificial pond near St. Michaelis in Saxony . It was created to supply water to the mining area on the Goldberg. The Hungerborn Water and its tributaries were dammed up. Its name was derived from the Rote Vorwerk, located approx. 500 m northeast of the dam. Today the inflow-free pond is used as wet grassland with temporary water flow to retain rainwater for the Freiberg industrial areas "Rotvorwerk I and II".
location
The pond, which is now dry, is located south of the Freiberg Hospital Forest or south-east of the Goldberg (479.3 m) on the north-eastern part of the district of St. Michaelis. To the east of the dam industrial area "Nord" rises in the Brand-Erbisdorf district, the heap of the Johannes-Schachtes; The industrial area "Nord" extends over the former mining site of the Johannes-Schacht and Max-Roscher-Schacht. To the north-east lies the “Rotvorwerk” industrial park in the Zug district . To the south is the fire dent through which the piped Goldbach flows.
history
Mine pond
The pond was one of the numerous projects by Freiberg chief miner Martin Planer to supply the area with impact water. It was laid out in 1577 for the new art built on the boy Stephan to deepen the water in the pits on the Goldberg and the pond site was bought out by Leonhard lower next Maß and other unions on the Goldberg. In addition to the Hungerborn, four other spring water flowed into the pond, some of which originated in the hospital forest or on the Roten Vorwerk and on the Dreschergut, as well as the water from the Johannes Erbstolln. As early as 1588, the “Young St. Stephan Art Pond” was enlarged and another basic purchase was made. The map series of the first Saxon state survey , made by Matthias Oeder between 1586 and 1614 and further processed by Balthasar Zimmermann until 1634, lists him as "pond so belonging to the young Steffan". Later, water from the Duke Auguster Kunstgraben was added to the pond from the Roten Vorwerk.
Mining at Goldberg came to a standstill as a result of the Thirty Years' War, and it took a long time to resume. This led to the fact that at the beginning of the 18th century the two neighboring landowners had assumed fishing in the pond and claimed to the " Electoral Stolln and Röschen Administration of Freiberg" that the "Männigsteich" had never been a mining pond.
The revitalization of the mining industry in the Brander mining area led to a sharp increase in the water requirement in the second half of the 18th century. During this time, the Rotvorwerksteich supplied the Silberspat Fundgrube, Beschert Glück Fundgrube and Matthias Fundgrube mines with water for artifacts. Because the Thelersberger Stolln was tapped by the introduction of the Tiefen Fürstenstolln into the Brander Revier, the New Hope God's Treasure Trove near Bräunsdorf , which had been lent since 1721 with the Thelersberger Stollnwasser, became a water quantum from the Upper Großhartmannsdorfer pond , which over the Kohlbach-Kunstgraben , Silberspater Kunstgraben and the re-excavated old Herzog August Kunstgraben in Rotvorwerksteich and from there in Goldbach by the fire Delle to St. Michaeliser valley to Striegis was headed. The costs of the repair, expansion and future maintenance of the Silberspater Kunstgraben, which was not part of the facilities of the “Kurfürstliche Stolln- und Röschen-Administration zu Freiberg”, should be shared equally with the unions in Silberspat Fundgrube am Goldberg near St. Michaelis, Beschert Glück Fundgrube behind the Three Crosses and New Hope God's Fundgrube at Bräunsdorf will be distributed. However, a long-running dispute developed over this, in the course of which, first of all, New Hope God's Treasure Trove renounced the waters from the Upper Großhartmannsdorfer Pond and finally in 1795 Silberspar Treasure Trove and solar vortices together with Holewein Treasure trove renounced the water from the Rotvorwerksteich.
In the years 1793 and 1794, the Stolln and Röschen administration carried out a major repair of the pond. The costs for the renewal of the wooden cone house, the floodlight with the floodlight house and bridge as well as the leveling of the dam and the Tarras wall totaled 377 thaler. The associated increased tension in the pond led to a dispute with the three landowners concerned. In 1795, a mining survey was carried out for the purpose of buying out the land and for the first refinement of the pond site. A water surface of 3,876 square rods and a tension of 13 cubits 6 inches above the bottom of the cone channel was determined.
However, the work on the Rotvorwerksteich was never completed. Although the Stolln and Röschen administration was able to reach an agreement on compensation after several years of negotiations with the St. Michaelis landowners Greifenhagen and Haubold, the third landowner affected, Börner, was not satisfied with the conditions and refused to settle and buy out. In 1799, the Sonnenwirbel mine including the Holewein treasure trove near St. Michaelis was lent with impact water from the Rotvorwerksteich for the construction of new artifacts.
After heavy water grinding had already occurred in January 1790 at the Beschert Glück Fundgrube in front of the 3rd Gezeug route location on the Beschert Glück standing south of the Richtschacht, the springs at the Roten Vorwerk and Threschergut dried up in the following years. The excavation of the Tiefen Fürstenstollnortes from Beilehn Hab Acht Fundgrube in the Goldberg after the corridors at Johannes Stolln and further on to the Pingenzügen in the Hospitalwald led to the drying up of all natural tributaries of the pond. Because of the Johannes Stehender and Schwarzfarben Spat corridors that graze under the pond, the pond could not be ruled out and flooded the Beschert Glücker mine, but a greater danger in the event of an overvoltage was a possible flooding of the Johannes Stolln, whose dry mouth was located directly on the north bank of the pond Since the pond only served as a reservoir for water from the Silberspater artificial ditch and no longer had its own water resources, it was for these reasons that the Stolln and Röschen administration could do without it. Before 1818 its dam was excavated, the remaining water surface at a maximum tension of 3 cubits 14 inches was 80,364 square feet. In February 1825, after another severe water crushing, water measurements of the inflow and outflow from the Rotvorwerksteich revealed a difference that suggested that leaks in the pond contributed to the water crowding at Beschert Glück. In September 1825, the dam was therefore breached and the water level lowered to 2 cubits 16 inches.
Immediately afterwards, disputes began between the Stolln and Röschen administration and the neighboring landowners because of unauthorized cultivation of fields in the pond area, removal of rainstones and the filling of the flood to create a driveway over the dam. In 1832 the area of the now completely drained pond was leased to the neighboring landowner for reclamation. The sale of the pond to the residents, intended by the Stolln and Röschen administration in 1850, was finally suspended due to concerns of the head of Beschert Glück Fundgrube because of the proximity of Johannes, who was part of the company's intentions, and the expected higher claims in the event of a buyback . The pond was never dammed again.
Reuse
In 1850, the Johannes Schacht was sunk to the west of the dam by Beschert Glück Fundgrube as a new open-pit to Moritzstolln on the Johannes Standing. During the operating time, a small part of the pond site was also dismayed with heaps of heaps. From 1951 to 1952, the VEB Bleierzgruben Freiberg, fire department, sunk the Max Roscher shaft not far from the Johannes shaft as the new central shaft of the Brander district, but never put it into operation. After the ordered cessation of the deficit non-ferrous metal mining, the "Rosa Luxemburg" mining industry was established in 1966 on the grounds of the VEB Leuchten- und Fluorescent Lamp Factory.
Rainwater retention basin
In the course of the construction of the Freiberg industrial park "Rotvorwerk I", the Rotvorwerksteich was designated as a rainwater retention area in 1992. In 1998 the old dam was sealed and a new monk system and a paved overflow were installed. A perforated insert in the Mönch ensures a delayed discharge of the inflowing surface water into the open ditch to the Goldbach. In 2000 the water flow was improved by increasing the permanent storage area. As a rule, the pond site is without permanent water retention.
After the overprinting for rainwater retention for the commercial area, the pond is classified as a temporary small body of water with a size of approx. 4000 m².
Trivia
On May 22, 1795, the melancholy fireworker Christian Gottlob Hähnel extinguished his entire family. His wife Eleonora injured Hähnel with a fascine knife and threw her into an open shaft near the Reichen Zeche. Then he went with his 14-year-old son Karl Heinrich to the Rotvorwerksteich, where he drowned the boy and himself. The high school teacher Johann Gottfried Merbeth published a funeral sermon for his murdered student.
In 1806 the Freiberg Markscheider and Stolln and Röschenschichtmeister August Friedrich Bollner drowned in the pond.
