The Sims is a river of Bavaria, Germany, near the country's southern border. A right tributary of the Inn, the Sims is approximately eight kilometers long, and is fed by the Simssee, a small lake.^[1] It flows into the Rohrdorfer Achen, close to its confluence with the Inn, near Rosenheim in the municipality of St. Stephen's churches. Initially, it runs along the edge of the municipal area from Stephanskirchen to that of Riedering.

Geography

Course

At its southern end, the Sims flows out of the Simssee to the north of Riedering at 470 m above sea level and immediately heads west through the wet Achalterwiesen meadows in the nature reserve on the southern shore of the Simssee . Here it picks up a second short outflow of the lake from the right, runs a good distance through the nature reserve and then touches the district of Eitzing on its southern edge at the Krottenhausmühle. Further downstream, it runs through the Kohlhauf and Pulvermühle sites before entering the forest area around the Lauterbacher Filze, where it picks up the Röthbach flowing in from Riedering-Niedermoosen in the south and then loops around another Stephanskirchen Pulvermühle. In the adjoining Röthbachholz, its longest mill channel branches off to the right to Landlmühle, which it then picks up again after crossing under the railroad line from Rohrdorf to Landl in the industrial area south of Landl. After the small river has also crossed under the Miesbacher Straße (St 2095) and passed through Murnau, it joins the Rohrdorfer Achen, which runs parallel to the Inn, on its western edge to the wedge-shaped alluvial forest along the Inn, and which joins the Inn from the right just 300 meters further on.
