Traun origin is called the source waters of the Traun in the Dead Mountains above Grundlsee .

The origin of the Traun is a spring ( 933  m above sea level ) and a waterfall, which is located in the valley that runs eastwards from Bad Aussee via Grundlsee. You come from a rock face below the Elm  ( 2128  m above sea level ). The waterfall then pours into the Kammersee at the southern foot of the wall . Regardless of the fact that the Traunquelle is named as such (and the river with Altausseer Traun north of Altaussee and the Kainischtraun on the Dachstein has two further source rivers), water still comes from the east from the Kammerboden (Kote 854  m above sea level just under one Kilometers into the valley). Officially, however, the Traun origin is mapped as the main strand of the body of water.

The spring in the karst of the Dead Mountains only flows intermittently and also falls dry in summer and winter, as does the channel from the bottom of the chamber. The source of the Traunursprung usually only pours around 20 second liters (l / s).

The Kammersee self draining underground further into the Toplitzsee , however, a breakthrough was made in the 16th century to the Holztrift a Klaus Wehr (was open only to wake rafts stimulus) to allow. This is always dry today. From a hydrographic point of view, the Traun-Ursprung body of water encompasses the entire water path to the shores of the Toplitzsee, i.e. it runs through the Kammersee, only the run to the lake is named on maps.

Below is the Grundlsee , the actual spring water of the (Grundlseer) Traun , the 2 kilometer long stream between Toplitzsee and Grundlsee is called Toplitzbach . The Traun then changes special names several times until it is consistently called “Traun”.

The wall of the Traun origin consists of stable Dachstein reef limestone , the source is a real fissure source . Above the karst plateau of the Dead Mountains, mainly Tressensteinkalk and Plassenkalk , there are other lakes, namely the Vorderer and Hinterer Lahngangsee and the Elmsee , (superficially) drainless trough lakes. The Elmsee drains safely to the source of the Traun, the Lahngangseen - and the Dreibrüdersee in the basin behind - rather via Vorderbach and Hinterbach directly into the Toplitzsee. Two important speleological objects can be found here with the salt furnace cave and the Elm cave system - the second is heavily water-bearing, but since it is entered from the two wind holes between Lahngang and Elmgrund, the exact discharge has not yet been researched. The catchment area extends from the White Wall to the Rotgschirr , roughly along the state border, north of the Spitzmandl into Upper Austria.

The complex flow conditions of the Traun origin - and also of the other Traun spring areas, the Traun is one of the larger Alpine rivers that come directly from the Limestone Alps - is a much studied research field in karst hydrography. The question of the “real” source of the Traun was discussed again and again. The fact that the Traun origin is actually named as the source of the Traun is now naturalized.
