River in Grünklosterberg

This is a small river in the area of Grünklosterberg, which is a part from the High Fens, a large Nature Reserve in Belgium. I couldn't find a name of this river but it's one of te rivers who leads to the reservoir Wesertall Sperre near Eupen (Belgium). Characteristic for this river is it's dark (almost black) water with high acidity.
