geography
Schmelzbachquelle
The Schmelzbach rises from a karst spring at the foot of the Blocksberg, on the northeastern outskirts of Peggau, at the entrance portal of the Lurgrotte , the largest stalactite cave in Austria. The spring water comes from the complex Lurbach system, which also includes the Lur grottos located under the karstified Tannebenkalkstock .
The 6.5 km long Lurbach sinks into stream shrinkage on the eastern end of the plateau near Semriach , flows through the Lurgrotten and, when the water level is high, partially emerges at the origin of the Schmelzbach. The main exit point, however, is the Hammerbach spring further south . The seeping Lurbach water can only arise in the Schmelzbach spring if this reaches a discharge of more than 200 liters per second.
Inside the cave, the Schmelzbach, which runs underground, flows along the guide path. He used to fall over several 7 m high rock cascades from the cave entrance. Around 1920, the cave spaces behind the entrance were drained for development, so that the stream today rises below the portal from an artificially created drainage tunnel, today's Schmelzbach spring. Since the 16th century, the head of the original outlet was used to operate the wheelworks and smelting furnaces , which gave the emerging stream its name.
course
After its source, the Schmelzbach runs westwards, crosses under the Bruck expressway and flows into the Mur after about 480 m from the left .
