Two subjects that are inextricably linked/bonded together

I'm doing a piece where I am trying to state that a place is linked/bonded together with a river tightly. Just using "linked/bonded" as a term seems weak, is there any phrase to replace them that showcases that the two subjects have to be together, that each individual may fail if separated.

Solution 1:

Two options are yoked and entwined.

From Merriam-Webster:

entwined: To become twisted together or around

Example: Now a new documentary will look at the history of this genre, in which the pastoral is routinely entwined with the painful.

yoked: to join as if by a yoke

Example using the place/river:

• The place is yoked to the river.
• The place is entwined with the river.
