The Millstone River begins in western Monmouth County and flows westward through northern Mercer County / southern Middlesex County, and northward through southern Somerset County, before draining into the Raritan River at Manville. Almost three quarters of its length is paralleled by the Delaware and Raritan Canal. Both the Millstone River and parallel canal provide drinking water to large portions of central New Jersey and provide recreational uses as well.
