The Ybbs (pronounced: [ ips ] ) is a right tributary of the Danube in Lower Austria.

Running and landscape

The source is located near Mariazell in the Lower Austria and Styria border at the foot of the Great Zellerhutes. The river is initially the name White Ois, about 5 km flow path he is called then Ois and about from Lunz am See to its confluence with the Danube at Ybbs Ybbs an der Donau.

The Ybbs has a tortuous course of the river and flows for a distance of about 130 km from south to north through the Ybbstal. Along the river are located mainly metal and wood processing companies. In the foothills of the Alps reached, it changes direction and flows north-east to the Danube.

The most important places along the Ybbs are Lunz am See, Gostling 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 on the Danube.

Economic Importance

Up to the 1980s, the Ybbs was in the lower reaches of one of the most polluted waters in Austria. By sewage treatment plants in the neighboring cities (especially Waidhofen an der Ybbs and Amstetten ) and mainly by the wastewater treatment of paper mill in Ulmerfeld - Hausmening and pulp production in Kematen an der Ybbs pollution has been reduced drastically.

The flow is also used for generation of electric power. A portion of the stream for Amstetten is produced in a hydroelectric power plant Ybbs. In Kemmelbach just before the confluence with the Danube a modern hydroelectric power station was built, which produces electricity for the town of Ybbs and their environment. Power plants are located in Opponitz (Vienna electricity) and in Ybbsitz ( Gaissulz ), which is used to supply the company Riess since 1937.

Formerly a working channel was derived in order to produce in Ybbs electricity since the 1890s in Kemmelbach. Thus, the lower reaches of the Ybbs suffered particularly in the summer of water shortage. This works canal has now been decommissioned and filled along with the power plant.
