The Otterbach , initially also called the Süssenbach after the confluence of its upper courses , is a 17 km long creek that runs roughly southwest through the Bavarian Vorwald in the Bavarian districts of Cham and Regensburg . After crossing the church village of Sulzbach an der Donau from Markt Donaustauf , it joins the Danube from the left . Together with the more important left Weismühlbach of its two upper reaches, it is even more than 22 km long.

geography

course

The Otterbach arises in the parish village of Süssenbach in the municipality of Wald in the district of Chams at around 477  m above sea level. NHN due to the confluence of the Weismühlbach , which is larger in length and sub-catchment area, on the left and approaching from the southeast with the Steinbach on the right and coming from the northeast .

From there it flows, initially also called Süssenbach , in loops that are particularly wide at the beginning, steadily in a south-westerly direction. After passing a dozen smaller towns in Wald, he crosses the border with the Regensburg district into the municipality of Altenthann , passes through the village of Forstmühle and then passes the large, community-free forest area of ​​the Forstmühler Forst in the northwest. Here he passes one after the other the Altenthanner Einöde Bruckhäusl on the left bank, its church village Heuweg on the right bank and at the height above the valley, the village Oberlichtenwald in the same position to the brook and the village Unterlichtenwald on the right of the course in the far estuary.

There, the most important tributary of the Sulzbach flows to the other side of the village , which together with its own upper course even exceeds the length of the Otterbach main line to this point, but contributes about a quarter less to the catchment area, and the state road St 2145 uses the valley from here . This now narrows again between steep forest slopes and the Otterbach changes to the area of ​​Markt Regenstauf , where it successively passes the deserted Neumühle and Klammer am Ufer. Then the valley widens into a large bay in which it flows between the hamlets of Hammermühle and Dachsberg.

Before the Scheuchenberg , the last almost south-flowing brook deviates to the right and south-west, crosses the church village Sulzbach an der Donau , runs under the state road St 2125 that follows the stream and then flows 150 meters further at about 327  m above sea level. NHN from the left into the Danube .

A popular hiking trail runs along the stream between the Forstmühle and Hammermühle.
