The Salmon Falls River joins the Cochecho River near Dover, New Hampshire, to form the Piscataqua River.[2]

It provides hydroelectric power at the New Hampshire towns of Milton, North Rochester, East Rochester, New Hampshire, Somersworth, and Rollinsford, and in Maine at Berwick and South Berwick. The final three miles of the river, from South Berwick to the Piscataqua, are tidal.

Local Abenaki Indians called the river Newichawannock (New-ik-a-WAN-nok), meaning "river with many falls". See Newichawannock Canal
