Schwarzwasser Valley

The river Schwarzwasser rises on the Hinterer Fichtelberg (1206 m) in the Ore Mountains, initially flows in a westerly direction and bears the name Seifenbächel as far as the Czech border not far from Gottesgab (Boží Dar).
The Plattner artificial ditch (Blatensky přikop) branches off at the now defunct Neumühle, which once fed black water to the mines in the Platten mountain area (Horní Blatná) on the Plattenberg as impact water.
In the Czech Republic, the villages of Försterhäuser (Myslivny), Zwittermühl (Háje), Jungehengst (Luhy) and Brettmühl (Pila) were located on the river.
At Wittigsthal, a district of Johanngeorgenstadt, the black water flows back to Germany and takes in the Breitenbach (Blatenský potok) coming from Breitenbach (Potůčky).
On the further course of the black water, which now flows in a northerly direction, numerous hammer mills have been built since the 16th century because of the iron ore deposits that occur there. Zain hammers, equipment hammers and stick hammers were operated in Wittigsthal, Erlabrunn and Breitenhof.Source and further information
