After passing through Almond Lake (where it receives a tributary from the north), and picking-up another tributary from the east-northeast, it becomes part of the county line, except for a small section entirely on Fulton/Milton side between Clarity Road and Hickory Flat Highway (SR 140), which may have been a former route for the river. There are also other places where the line diverges slightly to the west side of the river.
