Management of river in Norfolk town adjoining a lake (8)
I believe the answer is:
disposal
'management' is the definition.
(disposal is a kind of management)
'river in norfolk town adjoining a lake' is the wordplay.
'river' becomes 'po' (Po is an example**).
'in' is an insertion indicator.
'norfolk town' becomes 'diss' (I've seen this before).
'adjoining' says to put letters next to each other.
'lake' becomes 'l'.
'po' placed within 'diss' is 'dispos'.
'dispos'+'a'+'l'='DISPOSAL'
'of' is the link.
(Other definitions for disposal that I've seen before include "Jettisoning" , "Availability for use" , "Deployment - management" , "arrangement" , "Scrapping" .)
