The tile you're looking for is on position 9 22. (I believe) I also put it in the screen shot so you could see where its at. It's next to the sand tile. The little grass tile with the corner in it.

The problem with your rivers isnt about forks in the river and branching off. It's the river its self is straight. The river should twist and turn. If you look at a river it is never straight. There is always river bends and what not where the river turns. It needs to be curved and not striaght like an L

Look at the screen shots for what I mean. (I juse used any old tile to show the curving motion of how a river might look compaired to what you have.)
