The source of the river begins above Walbrzych, in the Wałbrzych Mountains, on the northern slopes of the Sylvan Massif, near the old Glinik.

The Walbrzych segment is partially channeled and flows under the city, visible on the surface only from the Old Spa district.

The river is heavily polluted with sludge from sedimentation tanks and flotation coal coking at Walbrzych mines.

The river discolouration from pollution is a heavy dark brown giving off a slight chemical odour.

The source of the pollution is near Legnicka Road, where the polytechnic college is situated (Politechnika Wrocławska w Wałbrzychu).
