It's a great lake (5)

I believe the answer is:

huron

'it's a great lake' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for huron that I've seen before include "Second largest of the Great Lakes" , "Great Lake" , "N. American lake" , "One of the Great Lakes of North America" .)

I've seen this clue in the Evening Standard.
