The Zethauer Kunstgraben is an artificial moat between the Mulda district of Zethau and Großhartmannsdorf in the Ore Mountains from the 16th century. It indirectly served the additional supply of impact water for the Freiberg mining and is part of the Freiberg Revierwasserlaufanstalt .
course
The ditch branches off at the southwest end of the Mulda district of Zethau at around 530 m above sea level. NN from the Zethaubach and then leads on its western slope in a north-easterly direction, where it runs through two short florets . After about 2.4 kilometers, the ditch swings to the northwest, piercing the watershed between Zethaubach and Helbigsdorfer Bach . The watershed between Helbigsdorfer and Müdisdorfer Bach is crossed by an approx. 300 meter long rosette southwest of Helbisgdorf. It reappears at the so-called Heidemühle and shortly thereafter flows into the south-east bank at about 490 m above sea level. NN in the lower Großhartmannsdorfer pond .
In 1826 August Schumann describes the ditch and its course in the state, postal and newspaper lexicon of Saxony as follows:
"[...] a pair of ponds are laid out in the upper village for the sake of the Zethauer Kunstgraben, which starts 1000 paces below the last property in the village, and, due to its slight slope, is getting further and further away from the depth of the valley, so that it over the parsonage already flows about 30 cubits over the stream; from here on it is forwarded through the Kirchberg in a rose, where there are a lot of crabs, then crosses the meadows of central and Niederzethau in great curves, thus reaching the pretty Wiesenthal, which separates it from the Großhartmannsdorf area, here - as on several Place - a hat, and finally pour it into the large (vulgo Großhartmannsdorfer, more correctly Helbigsdorfer) mine pond. "
history
The planned expansion of a water storage and supply system for Freiberg mining and metallurgy began on January 23, 1558 by the electoral order. From 1562, the construction of artificial trenches and florets took place in parallel according to the suggestions of the chief miner Martin Planer . In the course of this, the lower Großhartmannsdorfer pond was also strengthened. In order to increase the amount of water available in the pond, it was supplemented in 1564 by the artificial inflow of the Zethauer Kunstgraben. From then on, this diverted part of the water from the Zethaubach and smaller streams from the valleys southwest of Helbigsdorf into the pond.
Today the Revierwasserlaufanstalt is of supraregional importance for the service and drinking water supply of the Chemnitz , Dresden and Freiberg regions .
additional
The side walls of the trench are made of dry masonry , ie quarry stone with clay , without lime mortar. At the time, it was common to cover large parts of the trench with wooden slabs so that leaves and grass did not obstruct the flow of water, evaporation losses were kept low and accidents avoided as far as possible. Since the ditch is still used today for the service water supply, the rind cover can only be seen at some touristic important places, but otherwise replaced by concrete slabs.
