The Zschauke (also Zschaukegraben and Zschaukebach ) in the south of Dresden is next to the Nöthnitzbach an important right tributary of the Kaitzbach .

The source of the brook is on the northeastern edge of the Bannewitz district of Boderitz . From there, the Zschauke flows for almost a kilometer through a forest belt lined with agricultural land in a north-easterly direction. Around 650 meters of this, the stream marks the boundaries of Boderitz (west) and Bannewitz (east) and then at around 200 meters the border between Kaitz (west) and Bannewitz, thus also the Dresden city limits. For comparison: the total length of the city limits of the Saxon state capital is 139.65 km. A few meters after entering the city, the 142-meter-long Zschauketalbrücke crosses the course of the federal autobahn 17 and leads to the south-eastern Dresden-Südvorstadt motorway junction just outside the city limits on Bannewitzer Flur (3). The Zschauke then crosses under the federal highway 170 (Innsbrucker Straße) , which acts as a feeder road . The further course of the stream leads around 150 meters through a forest area that merges into agricultural areas to the east until the Kaitz location is reached. There the Zschauke enters its final, piped section. At the Possendorfer / Boderitzer Strasse junction, the approximately 250-meter-long Zschauke Abschlaggraben leads north along Possendorfer Strasse to the Kaitzbach, while the Zschauke runs east along Boderitzer Strasse and, from the next intersection, north along Bannewitzer Strasse to the Kaitzbach, into which the Zschauke opens north of the intersection at the central bridge. After a further eight kilometers, the Kaitzbach flows into the Elbe in Dresden's old town .

In its open stretches of water, the Zschauke is largely close to nature, and its course has not changed in recent centuries. The upper reaches of the Kaitzbach as well as the Zschauke and Nöthnitzbach are located on a slope and are partly surrounded by conventional agriculture, so that in the event of heavy rain, soil erosion of several 100 tonnes per hectare is possible, which is deposited in the form of mud on traffic routes and adjacent properties due to the resulting flooding as well as at the Kaitzbach can be transported to the Great Garden . On May 2, 1996, the catchment area of ​​the Zschauke was hit by heavy rain lasting about an hour, which brought 40 mm (= 40  liters / m² ). As a result, the piped culverts were blocked and the property on Possendorfer and Boderitzer Strasse flooded. As part of flood protection , the Zschauke flood retention basin with 4050 m³ was restored in Kaitz in 1997/1998 , and three smaller rain retention basins were created in Boderitz (1997, 1998, 2007). A rain retention basin with a capacity of almost 3000 m³ was built in 2003 as part of the construction of Autobahn 17 near the Dresden-Südvorstadt junction. During the flood of the Elbe in June 2013 , which was slightly lower than the flood of the century in August 2002 , levels falling several times were visible at the dammed Zschauke flood retention basin. However, a heavy rain event two weeks later led to damage to the pool.
