The Oderbruch is a landscape located at the Oder river in eastern Germany on the Polish border, with a small part also in Poland. It extends from the towns Oderberg and Bad Freienwalde in the north to Lebus in the south, in the county of Märkisch-Oderland in the state of Brandenburg. The Oderbruch is about 60 km long and its width varies from 12 to 20 km for a total area of some 920 km2. It is a slightly inclined plane descending from 14 m in the southeast to just one meter above sea level in the northwest. The German name Oderbruch comes from Middle High German brouch meaning a marshy ground, swamp or moor, while the Polish name refers to Bad Freienwalde.
