Source and mouth of the sitters

The Sitter is by far the largest tributary of the Thur and flows through the four Swiss cantons of Appenzell Innerrhoden , Appenzell Ausserrhoden , St. Gallen and Thurgau .

Surname

The name Sitter originated from Sidrona and probably goes back to Illyrian influences in the early days of the settlement of the Appenzellerland.

geography

Source / catchment area

The two source brooks of the Sitter, the Wissbach (1.35 m³ / s) and the Schwendibach (1.79 m³ / s), arise in the Alpstein and merge in the village of Weissbad to form the Sitter. It is 49 kilometers long from the junction of its source streams to the confluence with the Thur near Bischofszell . The Sitter develops from a mountain stream to a river with an average water flow of almost 12 m³ / s. Its catchment area has an area of ​​340 square kilometers and covers an altitude range of 460  m above sea level. M. to 2501  u m. M.

Tributaries

From the confluence to the mouth. Selection.

economy

use

Both the main river and the tributaries are used in many ways, other sections are almost untouched by humans.

The sitters and their floodplains serve

Hydropower

Originally, electrical energy was generated in eleven hydroelectric power stations along the Sitter . Seven of them are still in operation today. The largest share (87%) is attributable to the Kubel power plant of St. Gallisch-Appenzellische Kraftwerke AG (SAK) . The Gübsensee on the outskirts of the city of St. Gallen serves as a water reservoir.

Shipping and transport

Since 1975, the mammoth raft race with self-made floats has been held annually (usually on Mother's Day ) on a route over Sitter and Thur in front of thousands of spectators. In addition to the speed, the originality of the rafts counts.

The Gertau – Degenau ferry connects the communities of Hauptwil-Gottshaus and Zihlschlacht-Sitterdorf .

bridges

On its way, the Sitter is spanned by 50 bridges. Most of the bridges on the St. Gallen Bridge Trail lead over the Sitter.
