I disagree.  Water flow direction is recorded by the direction of the
way, same as steps "up" direction is recorded by the direction of the
way.  Oneway is not required for flow direction, though "reverse way
direction" might be.

Oneway should be used for movement / navigation restrictions.

Oneway as a flow indicator is incorrect.
