River Clyde emptied partly (3)

I believe the answer is:

dee

'river' is the definition.
(River Dee)

'clyde emptied partly' is the wordplay.
'partly' indicates a hidden word.
'DEE' is hidden within 'clyde emptied'.

(Other definitions for dee that I've seen before include "River name" , "Balmoral's river" , "Welsh/English river" , "Aberdeen's river" , "Name of many rivers" .)

I've seen this clue in The Times.
