You appear to have an unnatural river situation. Unless I am misreading it, the Aniyle River in Anub'Volthrak splits in two and goes on to flow into the ocean in two widely separated spots. That doesn't happen. Oh, now I see another one up in the Evenflow, but at least there's a city there that suggests it might be a canal bridging two tributaries for trade to Bodi.

Rivers start in the highlands and flow to the sea. As they do, they join up. They don't split, except around islands (the size of which is generally quite small) or in deltas (where they flow in multiple channels that change rather quickly) which take up a very small part of the river where it flows over flat ground into the sea.
