Resin found occasionally in rising creek by moat (5)
I believe the answer is:
amber
'resin' is the definition.
(amber is a type of resin)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for amber that I've seen before include "Yellow, translucent fossil resin" , "Ornamental fossil resin" , "gemstone" , "Stone" , "Honey-yellow colour" .)
