River flowing into Baltic Sea (4)

I believe the answer is:

oder

(Other definitions for oder that I've seen before include "German banker" , "European flower" , "School blazer insignia" , "River forming northern part of the German-Polish border" , "River flowing into the Baltic" .)

I've seen this clue in the Sydney Morning Herald.
