The Narraguagus River is a river located in the U.S. state of Maine with its mouth in the Narraguagus Bay of the Gulf of Maine. It flows through the town of Cherryfield and was formerly well known for its sport fly fishing for Atlantic salmon. This was a traditional highlight of late spring with anglers gathering from afar for the Memorial Day weekend fishing kick-off. The native salmon run has unfortunately been much reduced due to many different factors.
