Help With River Paths?

[Aerneth]

Hi everyone. So I'm working on the third try at my first map using Ascension's Atlas tutorial and it's looking great so far. Unfortunately the mountains, while looking good, have formed in a way to make mapping a river rather interesting. Perhaps someone could suggest a way I could incorporate a waterway without violating the laws of the River Police? I've attached a picture of the offending area in question. The area almost surrounded by mountains (circled by red) is going to be heavily forested and where the river(s) will be coming from. The red arrow is the path I would think the river would flow. I was thinking maybe a lake, but where would it drain to? Just for a sense of scale, the continent itself is about 2,000 miles (~3219 km) wide. Thanks in advance.
