The Rothwasser (Polish Czerwona Woda , Czech Oldříšský potok ) is a right tributary of the Lusatian Neisse in the Czech Republic and Poland .
It rises in the Jizera Mountains foothills southeast of the village Dolní Oldřiš (Niederullersdorf) in the Czech Republic, which belongs to the municipality Bulovka (Bullendorf) . After about 2.5 km, the red water flows into Polish territory at Miedziane (Küpper).
The former town of Sulików (Schönberg) lies on its further course to the north-northwest . Below at Mała Wies Dolna (Nieder Halbendorf) the Linda (Polish Lipa) joins on the right.
The red water flows through Ujazd (Moys), a district of Zgorzelec (Görlitz), and flows into the Neisse after 22 km west of the village.
