Master uneven flow (6)

I believe the answer is:

stream

'flow' is the definition.
(I know that flow can be written as stream)

'master uneven' is the wordplay.
'uneven' is an anagram indicator.
'master' anagrammed gives 'STREAM'.

(Other definitions for stream that I've seen before include "flower" , "River - current" , "play in real time" , "Fly" , "One small river" .)

I've seen this clue in The Mirror.
