Near Harwich on Cape Cod, the Herring River is popular with fly fishermen for herring fishing. This river is formed by several lakes and ponds emptying in and thru the salt marsh areas. The river feeds into Nantucket Sound. Each spring herring migrate from the ocean into this creek. The herring make their way up the river and swim up a man made fish ladder into the Harwich reseviour. Then keep going up the small stream in several more ponds and finally up into Long pond or they spawn all along the way.
During these spring runs and annual migration of herring , the striped bass and bluefish predator species will chase the herring from the ocean up into the creeks making for fantastic estuary fly fishing. This occurs from May 15th thru the month of June. And in some years the runs can start earlier in March depending on weather and water temperatures.
Following the herring migration, the main game species come upstream including striped bass and bluefish. These species can also be found on other Cape Cod rivers including Scortons Creek, Paines Creek, Pamet River, Bass River, Muddy Creek, Quivet Creek and Mashpee River.
Overall, Herring River is the 3rd most popular fly fishing river of all 5 fly fishing spots in Massachusetts.
