The Roth is an approximately 52 km long river in the Bavarian administrative district of Swabia , which flows into the Danube from the right and south near Oberfahlheim in the municipality of Nersingen in the Neu-Ulm district .

The Roth flows between the parallel Danube tributaries, the Iller, in the west and the upper reaches of the Günz , later the Biber in the east.

Name interpretation

The name Roth comes from the reddish color of the river, which is due to the relatively high iron content of the water. As the name Eisenburg suggests, the soil in the headwaters is very ferrous.

geography

course

The Roth rises in the Otterwald , a forest area north of Eisenburg (Memmingen) . After that it flows very steadily northwards. Near Winterrieden, it crosses the reed, which is criss-crossed by many moats, between the Klosterbeurer and the Kellmünzer Forest, where it picks up a first small Roth from the left , also known as the western Roth , which also drains the reed. Further down, the Roth branches off to the left at the market town of Buch, a second Kleine Roth , which later flows back again at Weißenhorn ; on the division it is also called Ostroth to distinguish it . Both branches drain the Obenhauser Ried west of Buch. After another north run, on which it finally crosses the alluvial forest to the right of the river, the Roth flows north of the Nersingen district of Oberfahlheim from the right and south into the Danube section between Neu-Ulm and Leipheim .
