The Seebach is an approximately 8 km long right tributary of the Aare in the Swiss cantons of Solothurn and Bern . It drains an area of ​​around 10 square kilometers in the Solothurn water authority and in the Bernese Oberaargau .

geography

course

The Seebach rises as Moosbächli at about 503  m above sea level. M. at Cholholz right next to the Etziken forest house in the canton of Solothurn. At the beginning it runs through Etziken and for the first time comes to the surface at the embankment. From here it flows after an arc in an easterly direction and passes Bolken in the north before it flows into the western half of the Inkwilersee . After leaving the lake, it flows mainly to the northeast through the canton of Bern. It passes Inkwil , Röthenbach , Heimenhausen and the Berken districts of Ober- and Unterberken . Here it flows at 417  m above sea level. M. from the right into the Aare.

Catchment area

The catchment area of ​​the Seebach is 9.97 km² and consists of 24.8% wooded area , 63.4% agricultural area , 10.4% settlement area , 1.0% water area and 0.4% from unproductive areas.

The mean height of the catchment area is 471  m above sea level. M. , the minimum height is 416  m above sea level. M. and the maximum height at 523  m above sea level. M.
