Canoeing locale (4)
I believe the answer is:
'canoeing locale' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lake that I've seen before include "Mere - organic pigment" , "A pigment; a body of water" , "E.g. Huron" , "Superior, for instance" , "Superior maybe < that's red" .)
