geography
course
The river rises west of Immenstadt in the Oberallgäu district . From its source, which rises south-west of the Immenstädter Horn , the Weißach flows north of the Nagelfluhkette in a south-west direction, and then changes from the Imberg ridge to the north-west run to Oberstaufen . Then the Weißach moves to the southwest, crosses the border between Germany and Austria at Aach and flows into the Bregenz Ach between Langenegg and Doren .
East of Steibis in the district of Aach im Allgäu , and south of Buchenegg , Markt Oberstaufen, the river plunges down the Buchenegger waterfalls .
Honorary valley
The upper Weißach valley between the source and the bend to the southwest (Hochgratbahn) is also called Ehrenschwanger Tal , after the name of a hunting lodge in this once very remote valley.
Tributaries
The Bolgenach, the largest tributary of the Weißach, flows between Doren and Krumbach.

Fish stocks
The resident fish species are brown trout and Mühlkoppe . In the lower reaches there are low stocks of grayling , rainbow trout and brook trout due to earlier stocking .
Hydropower plants
In the hamlet of Krebs, the river is dammed up into a lake , and the water is discharged from the pressure pipe of a hydropower plant with a height difference of over 30 meters. This and a smaller power plant on the Eibelebach of the Weißachtal-Kraft-Werke supply around 1000 people with electricity.
