Water goddess? (4)

Ross

I believe the answer is:

isis

I believe this clue is a double definition.

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

'goddess?' is the second definition.
(Egyptian god)

(Other definitions for isis that I've seen before include "banker in Oxford" , "Revered figure" , "Oxfordshire river" , "Egyptian deity" , "A dark blue flower" .)

I've seen this clue in the Evening Standard.
