Coming from garden, I leave flowing water (4)

I believe the answer is:

nile

'water' is the definition.
(Nile is an example)

'coming from garden i leave flowing' is the wordplay.
'coming from' indicates a hidden word.
'NILE' is hidden within 'garden i leave flowing'.

(Other definitions for nile that I've seen before include "Egypt's river" , "River of Egypt" , "River at Luxor" , "World's longest river" , "Current" .)

I've seen this clue in The Telegraph.
