The Obra is a 164 km long left tributary of the Warta in the Polish Voivodeship of Greater Poland . It rises south of Jarocin ( Jarotschin ) and flows into the Warta at Skwierzyna ( Schwerin an der Warthe ). There is a connection to the upper reaches of the Warta via the 25.7 kilometer long Moschiner Canal , which branches off at the city of Mosina ( Moschin ).
The towns of Krzywiń ( Kriewen ), Kościan ( Kosten ), Zbąszyń ( Bentschen ), Trzciel ( Tirschtiegel ), Międzyrzecz ( Meseritz ) and Skwierzyna ( Schwerin ) are located on the Obra .
In the period between the two world wars, the German-Polish border roughly followed the chain of lakes in the middle reaches.
