oneway indicates that traffic is restricted from traveling the other 
direction. I suppose this might happen in a busy canal system, but on 
virtually any stream or river, it is in error.

Version 2 indicates that the direction of flow is southwards. Version 1 
indicated that the direction of flow was northwards. In addition, 
version 2 indicates that the direction of travel was southward.
