Bloke reportedly producing natural water feature (6)
I believe the answer is:
geyser
'natural water feature' is the definition.
(type of naturally occurring spring)
'bloke reportedly' is the wordplay.
'bloke' becomes 'geezer' (synonyms).
'reportedly' indicates a 'sounds like' (homophone) clue.
'geezer' is a homophone of 'GEYSER'.
'producing' acts as a link.
(Other definitions for geyser that I've seen before include "spouter!" , "Steaming spring" , "upsurge" , "A jet of hot water from natural spring" , "Fountain of hot water from natural spring" .)
