This place needs a name

The Kisaralik River is disconnected here. Seems like an obvious fix but satellite differs drastically from the map so I don't want to affirm any other errors that might be here.

presumably these two unnamed rivers flow into the Kisaralik River?

If so they should connect to it, see https://waterwaymap.org/#map=16.22/60.783948/-160.68498&tiles=planet-grouped-ends to understand why
