The river Wutach originates as Seebach at the Feldberg mountain and was originally the source river of the Danube. Today the Wutach is a tributary of the Rhine. The Wutach begins approximately 3 km east of Lenzkirch after the union of the river Haslach, which flows through Lenzkich, and the river Gutach, which origins in the Feldberg region. The Wutach dug a up to 200 meter deep canyon into the earth's crust. An astonishing animal- and plant-variety can be found in the Wutach Gorge. Here grow 1200 kinds of ferns and flowers, and 1400 kinds of bugs and 590 kinds of butterflies are native here. The Wutach Gorge is a nature reserve since 1939.
