The Ybbs [ ɪps ] is a right tributary of the Danube in Lower Austria .
Run and landscape
The source is located near Mariazell on the Lower Austrian-Styrian border at the foot of the Großer Zellerhut . The river is initially called the Weisse Ois , after about 5 km it is called Ois and from around Lunz am See to the confluence with the Danube at Ybbs on the Danube Ybbs.
The Ybbs has a very winding river course and flows over a length of about 130 km from south to north through the Ybbsal . Mainly metal and wood processing companies are located along the river. In the foothills of the Alps reached, it changes direction and flows northeast to the Danube.
The most important places along the Ybbs are Lunz am See , Göstling an der Ybbs , St. Georgen am Reith , Hollenstein an der Ybbs , Opponitz , Ybbsitz , Waidhofen an der Ybbs , Sonntagberg , Kematen an der Ybbs , Amstetten and Ybbs an der Donau .
Economical meaning
Up until the 1980s, the Ybbs in the lower reaches of the river was one of the most polluted bodies of water in Austria. The pollution was drastically reduced through sewage treatment plants in the neighboring cities (especially Waidhofen an der Ybbs and Amstetten) and mainly through the wastewater treatment of the paper mill in Ulmerfeld-Hausmening and pulp production in Kematen an der Ybbs .
The river is also used to generate electricity. Part of the electricity for Amstetten is produced in a Ybbs hydropower plant . In Kemmelbach just before the confluence with the Danube, a modern hydropower plant was built that produces electricity for the city of Ybbs and its surroundings. There are also power plants in Opponitz (Wien Strom) and in Ybbsitz (Gaissulz), which has served the RIESS company since 1937.
Wien Energie has been operating the Hausmening hydropower plant near Amstetten since 2016, with an annual standard working capacity of 13,000 megawatt hours. In the past, a works sewer was diverted in Kemmelbach in order to generate electricity in Ybbs since the 1890s. As a result, the lower reaches of the Ybbs suffered from water shortages, especially in summer. This works sewer and the power station have since been shut down and filled in.
