Responding about water (4)

I believe the answer is:

pond

'water' is the definition.
(pond is a kind of water)

'responding about' is the wordplay.
'about' says the answer is hidden in the clue.
'POND' is hidden in the letters of 'responding'.

(Other definitions for pond that I've seen before include "Himalayan country" , "Small body of water" , "Small area of still water" , "Pool of still water" , "Small lake" .)

I've seen this clue in The Mirror.
