The Lombach (also Äschlisbach ) is an approximately 7 km long right tributary of the Ilfis in the Swiss canton of Lucerne . In contrast to most of the rivers in the Entlebuch, it does not drain via the Kleine Emme , but rather the “big” Emme into the Aare .

geography

course

The Lombach arises at 1093  m above sea level. M. below the Turner ( 1215  m above sea level ) and above Escholzmatt , where two 150 meter long spring streams flow together, each of which has its source in two springs. It initially flows in a south-westerly direction through the narrow, undeveloped and densely forested Lombachtal valley in the upper part , which is therefore also called Lombachängi (Lombachenge) in the uppermost section . At the Lombachgrebli farm , the valley widens and it now flows through agricultural area, which is surrounded by wooded hills. The stream turns in an arc to the east and passes the courtyards Hinter- and Mittellombach as well as Lombach and Grabenhof before it reaches Escholzmatt.

Here it turns to the southwest and flows through the southern part of the village. At Längried , shortly after Escholzmatt, it takes up the Alpbach and is now also called Äschlisbach. From here the creek is followed by the railway line and Hauptstrasse 10 . It flows here mostly surrounded by fields and only in a few places is a forest edge. After the Lombach has passed several courtyards, it flows into Wiggen at 786  m above sea level. M. from the right into the Ilfis.

Catchment area

The Lombach drains an area of ​​13.6 square kilometers in the upper Entlebuch. This is made up of 52.7% agricultural area, 45.4% near-natural area and forest area and 1.9% built-up area. The highest point of the catchment area is 1736  m above sea level. M. and is located on a ridge south of the Beichlen ( 1769  m above sea level ). The average altitude is 1035  m above sea level.
