Floodgate (6)

Ross

I believe the answer is:

sluice

'floodgate' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for sluice that I've seen before include "Water flow control gate" , "really wet" , "Water drainage channel" , "Wash or rinse with a stream of water" , "Conduit for a rapid flow of water" .)

I've seen this clue in The Washington Post, the Universal and The Telegraph.
