The will of Robert Livingston, dated 1728, refers to "a creek commonly called Anthony's kill.
In the short spring snowmelt season it is "a class II run with several named rapids."

At a later time the Mohawk became established in its present course, and the Anthony kill, draining the old channel as far back as the divide at the head of Ballston Lake, is the shrunken remnant of the much larger stream through whose erosive work the present relatively large valley was formed.
