The Vöckla is a river in Upper Austria. It rises on the Mondseeberg northeast of Mondsee and flows approximately 47 km away at the World Premiere Ager. The catchment area of the river is 446 km ², the average flow at the mouth 8.8 m³ / sec

Course

The Vöckla derived from several source streams on the Mondseeberg in the area of ​​bog moss Wild in the municipality of deep trench and first flows north. At a length of about 2 km, it forms the border between Upper Austria and Salzburg, otherwise it runs entirely in District Vöcklabruck. For Franken market it changes its direction to the east, and Voecklamarkt Timelkam happens. In Strasbourg (municipality Timelkam ) the Vöckla meets almost on the Ager, the rivers are only 200 meters apart. Both, however, change their direction by almost 180 °, the Vöckla turns north, flowing through Vöcklabrucker opens only below Vöcklabruck in the Schalchhamer Au in the Ager.

Inflows

The most important tributaries are the Fornacher Redlbach shortly before Voecklamarkt, Franks Burger Redlbach after Voecklamarkt and Ampflwang Bach and the drought Ager at Timelkam.

Economic use

In many cases, the water is discharged into the Vöckla a mill stream. The steam power plant Timelkam, earlier, now powered by brown coal with natural gas, used cooling water from the Vöckla.

Environment

Is now intervened heavily in the natural course and water balance of the Vöckla particular through regulatory and numerous weirs. The original meandering course is visible only in a few places. In the upper reaches in the communities deep ditch and Zell am Moos Vöckla runs still relatively natural with one dominated by willows and ash woodland shore. In the further course can still be single natural sections with accompanying woody banks and smaller riparian forests, which are mainly formed as ash Nauen, as well as gray alder and willow Nauen.

Fauna

The Vöckla belongs to the trout region, mainly fish species are brown trout, grayling and rainbow trout. In the upper reaches and its tributaries the stone cancer is still relatively common.

Water quality

The water quality is affected by intensive agricultural use and industrial and commercial enterprises in the catchment. In the upper reaches, the Vöckla grade I to II, in the lower course grade II. The cooling water usage by the power plant Timelkam has in the past often lead to excessive heating of the Vöckla in the winter months and thus damage to the fish.

Name

The river's name first appears around 790 in the Notitia Arnonis as Feckelisaha and Fechilaha on. Attempts are often made to derive the name from the Celtic, for example, from aha ( Ache river) and fehil (fish ) or foecke ( Torch ), the latter based on torches that were lit as a signal fire on top of hills.
