The Albrechtsbach , in Upper Sorbian Albrechtowka or Hołborka , is a small left tributary of the Kotitzer water in the Upper Lusatian region in Saxony .
course
The source of the Albrechtsbach is about 2 km south of the district of Rachlau in the municipality of Kubschütz at about 300 m above sea level. NN on the north slope of the Czorneboh . The stream initially flows northwest towards Bautzen , then swings northeast and is crossed by federal road 6 west of the Bautzen district of Auritz . On the other hand, in some maps and in popular parlance , the Boblitzer Wasser , which rises in Boblitz near Oberkaina and flows into the Albrechtsbach near Nadelwitz from the left, is also referred to as the Albrechtsbach . For this reason there is a street called “Am Albrechtsbach” in the Strehla district of Bautzen .
In the further course of the Albrechtsbach flows through Niederkaina , where it turns to the right on an east-northeast run. Then he passes the place Kreckwitz , where he flows from the main bridge of the place through the so-called flood channel, an approx. 2 km long artificial river bed. This dead straight ditch ran parallel to the natural stream for several years. This showed a multitude of meanders and lush bank vegetation, but it was then filled in in the late 1980s in the GDR to enlarge, merge and ameliorate useful land, a controversial undertaking at the time. The old course of the brook can still be recognized today by some trees that stand in the middle of today's field.
Then the stream crosses under the federal motorway 4 and then reaches Kleinbautzen and Preititz . After another 1.5 km the Albrechtsbach flows into the Kotitzer water after a run of about 16 km . Just before its mouth, the Albrechtsbach is approx. 2.5 m wide and between 40 and 70 cm deep. The flow velocity is approx. 60 cm / s at normal water level.
Flood
The Albrechtsbach is usually a very small and calm brook that has an average width of about 1.6 m and a depth of 40 cm. But it is known to the residents as a very capricious and unpredictable brook; because it swells very quickly in the right weather and overflows its banks, within two hours in heavy rain it can grow into a torrent of over 3 m water depth. (The last time it happened in 1981 was the flood .) It even regularly floods immediately adjacent houses, gardens and streets, causing great damage every year. To date, there is no effective flood protection, for example through retention basins or other measures. The reason for this is, among other things, the inconspicuous water flow in the "normal" periods.
Water quality
Until industrialization in the times of the GDR, the Albrechtsbach was a very clean, spring-clear stream. Contemporary witnesses report that trout could be found in the Albrechtsbach. This changed from the 50s, wastewater from industry and sewage treatment plants, especially from Bautzen, now polluted the stream very heavily. It stayed that way until the 1990s. At that time the Albrechtsbach was a stinking, black, sometimes milky white body of water, without any animal or vegetable inhabitant. Since then the water situation has improved, as of today (2012) the water quality has recovered significantly.
