What is shown here is the river modellized with OSM's common datamodel 
where a river is represented with a connected set of ways, some of them 
crossing trough lakes with a subjective path. What this simple datamodel 
doesn't show, is the complex water flow trough water bodies.

I guess you are free to replace the ways with your own subjective path 
if you feel like to.
