There's no getting to the nearest bank from here (9)
I believe the answer is:
midstream
'bank from here' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for midstream that I've seen before include "Furthest from banks" , "Part-way through a course" , "centre" , "At halfway point in current" , "halfway across the water" .)
