Wyna (river)


The Wyna is a river located mostly in canton of Aargau, but also in canton of Lucerne, Switzerland and runs through the Wynetal. It is a tributary of the Suhre. The Wyna is 32 km long. Larger towns in Wynetal are Beromünster, Menziken, Reinach and Gränichen.

River

The Wyna is started by several headwaters south-west of Neudorf in the Lindewald, 17 km north-east from Lucerne. Near Underdorf, the Lochbach, or Hole Creek, which starts in the Chegelwald, west of Neudorf, joins the Wyna. Then, it runs north through Beromünster, through Menziken and Reinach, west of Zetzwil, through Oberkulm and Unterkulm, through Teufenthal, and through Gränichen before joining the Suhre at 385m in Suhr, which joins the Aare further north, just three kilometres later.
Tributaries that feed the Wyna include the Lochbach, Moosbach, Schwarzenbach, Rickenbach, Vorderdorfbach Zetzwil/Totenbächli, and Dorfbach Gontenschwil/Sagenbach, Dorfbach Teufenthal, Pfendelbach, Refentalbach, Lochbach.

Valley

The valley, the Wynetal, is fairly narrow, with an average width of about 500 meters, and drops very smoothly from 670m a.s.l. in Neudorf to 406m a.s.l. in Gränichen. Quite steep hills rise on both sides, carved by tributary valleys. In the east, a mountain range separate the Wynetal from the Seetal with the Hallwilersee and the Baldeggersee. The mountain range in the west separate the Wyne Valley from the Suhretal with the Sempachersee, from which the Suhre rises.
Municipalities found in the Wynental from beginning to end of the Wyna are: Neudorf, Beromünster, Burg and Menziken, Pfeffikon and Reinach, Leimbach, Gontenschwil, Zetzwil, Oberkulm and then Unterkulm, Teufenthal, Gränichen, and finally Suhr. The general region is also known as the Stumpenland due to the cigar industry that once centered in Menziken.

Glacial genesis

The upper portions of the valley was carved by the Reuss Glacier. Large moraine deposits remain at Zetzwil and Gontenschwil. The surrounding hills are largely molasse.

Transportation

Connecting road 23 runs along the Wyna for the majority of the valley's length from Beromünster to Suhr. This road is referred to variously as Aargauerstrasse, Hauptstrasse, Aarauerstrasse, Wynentalstrasse, and numerous names north of Teufenthal and is a popular cycling route. The WSB, a narrow gauge railroad, serves the Wynental. The Wynental branch of the WSB runs from Aarau to Menziken.
