The Lauterbach is a 9.4 km long orographically right tributary of the Werra in Thuringia , Germany .

course

The Lauterbach rises east of Berka in front of the Hainich , on the saddle between the 468 m high Löhberg im Hainich and the 424 m high Lohberg south-southwest of it, from several sources. The Lauterbach valley forms the Berka-Mihlaer Mulde , the river only gathers north of Berka from a number of small brooks and is also strengthened downstream by many lateral tributaries. These have cut shallow, deep gullies into the sloping layers of the Keuper . Strong, tectonic springs ensure the water supply even in midsummer, for example the Sülzenborn spring south across from the Burgberg and the one in Trippel .

Initially, the creek flows three kilometers through a deeply incised and winding valley, initially directed to the northwest and finally to the west, until it meets the Augraben on the southern edge of the municipality of Bischofroda . Here the direction of flow changes again to the northwest. Below Lauterbach to the locality of Mihla there is a short, natural section. In Mihla, the river is largely in a walled river bed and reaches the Werra at the Gray Castle .

Surname

The name could be derived from loud = clear and pure , the municipality Lauterbach is named after the river.

Economic history

A few flour mills can be found along the course of the river .

Flood protection

In the flood disaster of May 23, 1978, triggered by heavy rain, major economic damage was reported in the towns of Bischofroda, Lauterbach and Mihla, which led to the construction of two flood retention dams in the Bischofroda district:

  • The retention basin Bischofroda I was built 1985–1986 and blocks the valley of the Sülzaue and thus the headwaters of the Lauterbach. The maximum permitted storage volume is 200,000 m³. The dam is 9.5 m high and allows a maximum storage height of 8 m ( location ).
  • The retention basin Bischofroda II was built from 1987 to 1988 and blocks the Ebental north of Bischofroda. The maximum permissible storage area should be 4.5 ha. This dam also allows a maximum storage height of 8 m ( location ).
  • The retention basin Berka vd Hainich on the Augraben east of Berka is primarily used for irrigation ( location ).
