🚧 Herrenwieser Schwallung

The Herrenwieser Schwallung is a splash dam, built in 1844–47 of bunter sandstone, near Herrenwies in the Black Forest, which impounds the waters of the Schwarzenbach stream into a pond. In the days of timber rafting it was periodically opened and washed the fallen logs or timber rafts downstream into the valley. Today the dam acts as a bridge over the Schwarzenbach.
