The Jona is a river in the Swiss cantons of Zurich and St. Gallen , after which the town of Jona in the municipality of Rapperswil-Jona is named.
From the source to the mouth
The Jona flows through the following municipal areas:
- In the area of the canton of Zurich : Hinwil , Fischenthal , Wald , Dürnten , Rüti and
- in the canton of St. Gallen : Rapperswil-Jona .
The source of the Jona is located near Schufelberg in the municipality of Hinwil on the eastern slope of the Allmen . The Jonatal extends from Gibswil south to the village center of Wald. Here the Jona is fed from the left by the Schmittenbach (source on the Schwarzenberg, in the district of Goldingen ). Below Wald, the Jona flows westward through a steep-walled gorge (the Grundtal), which is bridged with a viaduct by the Tösstalbahn (S26 of the Zurich S-Bahn ) . From here on, the Jona forms the municipality boundary of Rüti , initially with forest, after about 500 m with Dürnten . It flows further west along the pilgrim path (Jonatobel) and Tannertobel and finally reaches Tann . Between forest and fir it overcomes a height difference of 100 m. At Tann (Joweid) the Jonah turns south and is fed from the right by the Schwarz . The Schwarz rises on the Ornberg on the southwest flank of the Bachtel, and drains the drumlin -shaped plain between Wetzikon and Dürnten (right tributary Mülibach ), parts of Hinwil ( Rütibach / Berenbach ) and Bubikon ( Egelsee ). Hinwil forms the watershed between the Jona- and the Glatttal ( torrent ).
The Schwarz forms the municipal boundary between Rüti and Dürnten, so that from the confluence the Jona flows through the Rütem municipality. In Rüti, the Jona flows into the Dachseggbächli from the left . Below Rüti, at Wydenchlösterli , the Jona becomes the canton border between Zurich and St. Gallen for a short distance. The Jona is crossed here by the Oberlandautobahn (A53) and turns to the west, now within the municipality of Jona-Rapperswil, in a ravine between Aspwald and Platten (Joner Wald, Hackenest, Bettlerwäldli, Grunau) along the railway line (S5 and S15 ). Above the village of Jona it turns again to the south (Lattenhof) and is fed from the left by the Latten brook (which drains Laupen and parts of Goldingen ). In the center of the town of Jona, the river was channeled, which quickly results in differences in the water level. The Jona finally forms a small alluvial cone and flows into the Obersee at Busskirch (near the Stampf seaside resort ) .
Name and story
The Jona (also Jonenbach ; dial. Joone; Joonebach ) shares its name with the Jonenbach in the Säuliamt , a tributary of the Reuss . The name is first documented in 834, Latinized as Johanna , in the name super Johannam fluvium (also the first document for the place Jona), Middle High German (1243) as de Jonun . A derivation of Roman * Jauna via Old High German * Jōna is assumed , ultimately from a pre-Roman * Jounā , derived from an idg. Root * ieu- .
The Murerplan of 1566 writes for the place Jonen and for the river Ione . The Gygerplan from 1667 writes for the place Jonen and for the river Jonen fl. The Alemannic form of the name is Jōne n ; The current spelling in -a is a learned Latinization from the 18th century (in Scheuchzer (1752) " Jona , die Jonen").
As early as the Middle Ages , mills used the water power of the small river. Already in 812 a previous building of the parish church Jona on a hill directly at the Jona, in the flood area between the Aspwald and the estuary delta at the Obersee, is mentioned. In 1259, the Wydenklösterli buildings were built on a bend in the Jona river in the Rüti Forest , in what was then the territory of the Counts of Rapperswil ( in what was later to become the municipality of Jona, not far from the border with neighboring Rüti ).
As a renewable energy source , the Jona made a major contribution to industrialization in the 19th century , especially in the neighboring communities of Wald and Rüti, and to the prosperity of the region and its textile industry .
