geography
course
The Twannbach rises on the Montagne de Diesse , north of the hamlet of Châtillon belonging to the Plateau de Diesse , at an altitude of about 806 m. It flows first in a northeasterly direction. At Sur les Moulins, a hamlet of Plateau de Diesse, he makes an arc and turns his direction south. It digs its way through the narrow Twannbach Gorge and finally flows into Lake Biel at Twann , in the Kleintwann district.
