The second pic shows the way things would go as is. The river snakes around and heads north but there is this huge bay sitting so close...it looks like a perfect place for a river to empty out in. The third map shows how I think things should go. It's purely my own opinion, though, so do what you will with that. Now that I look at this thing as a thumbnail, it looks a lot like Europe and my idea of the scale could be way off so you could have rivers doing anything if this, in fact, is meant to be Europe-like.
