Rott (Amper)

The Rott at Stillern

The Rott is about 20 km long, south-westerly flow of the Ammersee in Unterdießen in the district of Landsberg am Lech in Bavaria.


The Rott arises as Rottgraben west of polling Kugelsbühl in the Weilheim -Schongau, running half a kilometer to the west and then about a mile north-west to the inlet of an approximately equal length inflow from the south at Wessobrunn - Blaik, in the inflow direction it moves on then north. After just a few steps walk from left to the Schrallengraben which arises significantly higher at the upper slope of the Schrallenwaldes east of Wessobrunn - Postal, a little later from the same side of Ulrich Bach. Further down it feeds the elongated Zellsee in Moosmühle the community. After its northern tip at the Sähmühlensiedlung walk home from Weilheim in Oberbayern runs from left to Schlitt Bach, who created west of Wessobrunn and is fed by many short slope streams in the south. From here the water is now called Rott.

In a damp Wiesenaue the Rott travel further north between the forest areas Lichtenau right and Stiller forest left, right at the beginning accessed from the side of the silent forest of Mühlbach the Rott, soon after the stone ditch which runs through it from its southwestern edge of the Wessobrunner village Haid. Even before the hamlet Stillern in the floodplain, the first district of Raisting on the left bank, flows from the left to the Kohlgraben, about the boundary between the Silent Forest and the north Bavaria subsequent casting. Then, the Rott, after she has now turned to the north-northeast, from this great wooded area in quick succession the Rehgraben and the more important Michel Bach on. At the mouth of which ends on both sides of the forest and the water enters the corridor landscape around Raisting, which it then passes just outside the eastern edge. The Rott passes through the north equal to the village subsequently Ertlmühle where a weir accumulates the waters and the Möslegraben from the left slope feeds the mill pond. A moment later she is crossed by the railway line Weilheim- Augsburg and the county road 9 of the district Weilheim- Schongau, next to the road bridge stands the hamlet Rothbad a level of the Water Management Office Weilheim, right after that again here the Rott runs from the left slope of the Ammertalebene, in the already flows to a small ravine from the moat.

Then the Rott flows through the plains south of Lake Ammersee, which is crossed by drainage ditches and is further drained to the south. There she meets along with coming from the right and very meandering Old Ammer. This Old Bunting is the former lower reaches of the Ammer, who was separated from this about two kilometers south-east of the confluence in the years 1920-1924, after they had dug a new bed for the bunting. The oxbow lake remained after correction without passing, but since 2002, receives back from the bunting through a steel pipe under the dike Ammer through some water, the average amount but still significantly outperforms the rule of the amount of water Rott. From official side the river bed of the former Ammer underflow is attributed today the Rott from the confluence. The Rott flows in this still about three kilometers to the north and ends at the tip of a narrow, about half a kilometer long Verlandungs ​​Peninsula east of Unterdießen and now in the district of Landsberg am Lech in the Ammersee, the then drained the now Amper called Ammer.

Flood protection

After the losses of the 2002 flood, the community Raisting applied to the Water Authority Weilheim a feasibility study for flood protection measures. Narrow at high tide is the Rottbrücke in place Raisting. The municipality decided because of the high costs of an estimated 6 million euro against the initially desired three flood retention basin upstream before Raisting and thus for the inner-city development of protective measures by increasing existing and construction of new dams to about 200,000 €. These measures were implemented in three phases by 2009.


The Rott was straightened and diked in the lower reaches in the twenties of the 20th century. Thus, the meadows could be used as feed to the Rott meadows. Previously, only one was possible use as litter meadows because of the frequent flooding in the harvest time. Now that you gone over to the dismantling of the Rott to a natural body of water. 2004 saw the restoration of the lower reaches of the Rott downstream behind Raisting to the meeting with the Old Ammer. Then they began weirs and crashes in Sohlrampen convert to restore an ecologically balanced Bach system throughout its course to allow aquatic life again walks in the river.

Origin of the name

The Rott is attested by 1065 in the Wessobrunner founding legend as Rota. Rota could be found on Indo-European * rota "wheel" to go back and mean something like " the hurrying water." More likely, however, is a name of education as a result of the Bavarian land grab from the Old High German substantivized adjective red "red", resulting in " the Red " would as important. The appointment may be made ​​on the basis of red creek bed color or because of swampy water.

In the Wessobrunner founding legend also " Rotwald " is the great forest, which ( together with forestry ) extended to the territory of the present municipality Wessobrunn called without that it becomes clear what applies to the qualifying expression.
