Lough found in Eastern Europe (4)

I believe the answer is:

erne

'lough' is the definition.

'in eastern europe' is the wordplay.
'in' indicates a hidden word.
'ERNE' can be found hidden inside 'eastern europe'.

'found' acts as a link.

(Other definitions for erne that I've seen before include "Flier" , "Lough of the North" , "bird of prey" , "Fish-eating sea eagle" , "Irish river - sea eagle" .)

I've seen this clue in the Irish Times (Crosaire) and the Irish Times.
