Presumably, one expects to find you well - bringing you to the watering hole! (6)
I believe the answer is:
dowser
'hole' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for dowser that I've seen before include "One who searches for underground water" , "He uses a divining-rod" , "Detector of underground water" , "Israel/Jordan lake" , "Drowse like water-seeking man" .)
