Those maps are not too bad for ones to start with. The first shows something we call "river violations" (hmm err, how would you say that in french... riviere interdits ???). We see this a lot here. If you look at the post above me by Steel General he has a badge of 'River Police' as part of a group of the guild to pick up those river problems. There are some notes about how rivers flow and when they split or join up.
