House where river meets bay (5)
I believe the answer is:
cover
'house' is the definition.
'river meets bay' is the wordplay.
'river' becomes 'r'.
'meets' says to put letters next to each other.
'bay' becomes 'cove' (I've seen this before).
'r' put after 'cove' is 'COVER'.
'where' is the link.
(Other definitions for cover that I've seen before include "Shroud" , "Encompass" , "(Put) lid (on) - fielding position - insurance" , "Conceal, screen" , "Deal with" .)
