The Kollbach is a left tributary to the Danube , which mostly flows in the Deggendorf district .

course
The Kollbach arises on the north side of the Vogelsang in the Bavarian Forest through the confluence of a total of 18 source streams (11 in the municipality of Bernried and 7 in the municipality of Gotteszell) over a distance of approx. 1.8 km and 260 meters above sea level. Having already reached the Grafling municipality, the stream flows between the hamlets of Mühlen and Bergern, 1.2 km eastwards to the north side of the Graflinger Valley. The Kollbach flows through this valley in full length and crosses under federal highway 11 a total of three times until it reaches the city of Deggendorf near Niederkandelbach. Most of the last 3.5 km of the stream no longer correspond to its natural course, the stream is mostly canalised.
