Rode around a river (4)

I believe the answer is:

oder

'a river' is the definition.
(River Oder in central Europe)

'rode around' is the wordplay.
'around' indicates an anagram.
'rode' with letters rearranged gives 'ODER'.

(Other definitions for oder that I've seen before include "German river that empties into the Baltic Sea" , "River that, with the Neisse, forms the German-Polish border" , "East European river" , "European banker" , "flowing water" .)

I've seen this clue in The Irish Independent.
