The Gelbach is a 39.7 km long northern ( right-hand ) tributary of the Lahn in the southern Westerwald via its source river Aubach .


In the 19th century the Gelbach was named as the Gelber Bach or Gehlbach .



The Gelbach near Wirzenborn

The Gelbach is created in Montabaur by the confluence of the Aubach and Stadtbach . It flows into the Lahn at Obernhof and reaches an average water flow of 2.46 m³ / s.

The scenic valley of the lower course of the river, cut deep into the landscape, from above Ettersdorf to above Weinährs, together with the estuary valleys of the Bornbach es (left = east) and the Seelbach es (right), forms the natural area of Gelbachtal . In Weinähr , near the mouth, some viticulture is practiced.

Catchment area and tributaries

The Gelbach has a catchment area of ​​221.2 km² and flows through the southern edge of the Westerwaldkreis and the Rhein-Lahn-Kreis .


The town of Montabaur lies along the course of the river and, downstream on its boundaries, the towns of Wirzenborn , Bladernheim , Reckenthal (west above the valley), Wüstung Sespenroth (existed as a town until 1853) and Ettersdorf. Isselbach , Giershausen (to Isselbach), Kirchähr , Dies (to Gackenbach ) and Weinähr also follow .

Floodplain sediments

Most of the floodplain of the Gelbach and its tributaries was not deposited until the High Middle Ages . They are primarily the result of man-made deforestation and subsequent cultivation of hillside locations. It is assumed that mining ( Leopoldine-Louise mine ) in the Gelbach Valley had an impact on this process, which dates back to at least the 16th century . Investigations in 2008 and a. at Ettersdorf and Reckenthal .
