Well, now you get to meet one of the Guild's river police officers (me!) so pull over and show your license and registration...
Your map features an impossible river system - I see you haven't read the thread Gidde, pointed out in your introduction thread. Your rivers are doing things that would never happen in the real world, or in a believeable fantasy world.
First of all a delta close to the mouth of the river is the only time a river forks downstream, and river deltas are fairly rare in the world - only the largest rivers have them and only when extensive flatlands near the mouth force the river to drop sediment into the water and create multiple channels to drain into the sea.
Otherwise rivers never fork downstream. Forks occur when two rivers join to form a single larger channel heading for the sea. You've got four different downstream forks - everyone of them, a river violation.
This means your lake should only have one river exiting from it (as in your map), but only one river reaching the sea from that. Your lake could have several rivers feeding it, but only one exiting it. You could place other rivers that don't rely on the lake as the source, with rivers joining in the forks and reaching the sea.
Please read both of these threads on river systems to get a full primer on what you need to know to avoid such violations in the future!

Lots more to learn, but getting your rivers right is your first priority!
