Rescued from incredibly deep river (9)

I believe the answer is:

reprieved

'rescued' is the definition.
(reprieving is a kind of rescuing)

'incredibly deep river' is the wordplay.
'incredibly' is an anagram indicator.
'deep'+'river'='deepriver'
'deepriver' anagrammed gives 'REPRIEVED'.

'from' is the link.

I've seen this clue in The Independent.
