Land in the water (4)

I believe the answer is:

isle

This clue is a double definition.

'land' is the first definition.
(isle is a kind of land)

'in the water' is the second definition.
(I've seen this before)

(Other definitions for isle that I've seen before include "Dogs, for example" , "somewhere surrounded by water" , "being impossible without water" , "'There is an ..., a bonny ...' (rugby anthem in the South)" , "Insular place" .)

I've seen this clue in The Globe and Mail, The Daily Mail, the Evening Standard, the LA Times and The Wall Street Journal.
