Forbach-Herrenwies - Herrenwieser Schwallung

Flumes are facilities that were once used for rafting. The water was dammed on the mountain side. On the valley side, the wood to be rafted was deposited in the "raft room". When the weirs were opened quickly, the wood was swept up and transported down into the valley on the surge of water. The raftsmen had to repeatedly loosen wedged logs. A not entirely harmless spectacle that attracted many onlookers at the time.

The surge was built in 1844 to replace a wooden predecessor, but was only used for just over 10 years.

On the valley side, a footpath leads to the banks of the stream. An idyllic spot that also offers a great view of the imposing structure.
