About the Housatonic River Estuary

Anglers who know the Housatonic as a trout river in the northwest hills are often surprised to learn how good the other end of it is. Below Derby the river becomes tidal, and the last several miles between Stratford and Milford are a broad estuary of channels, mudflats and salt marsh that empties into Long Island Sound. The marshes around Nells Island are the heart of it. The combination of a large river mouth, extensive marsh, and the strong tidal currents of the western Sound makes this one of the most dependable striped bass estuaries in Connecticut, and it produces fish from the first warm weeks of spring until the water goes cold.

Striped bass are the fishery and the reason most people come. They hold on the channel edges, on the bars at the mouth and in the marsh drains on the falling tide, and the pattern is almost entirely a function of current rather than time of day. Bluefish arrive with the summer and will push bait to the surface across the flats. Summer flounder work the sandy channel edges, winter flounder use the deeper holes early and late in the season, scup fill the structure, and weakfish appear in some years in real numbers. Blue crabs are abundant through the summer and American eel and menhaden form much of the forage base. Small boats and kayaks reach the best of it; there is useful shoreline access at Stratford Point and in the state lands along the marsh.

The gauge near Nells Island reports water temperature and nothing else, which is exactly the right number for this water. Striper movement in a western Sound estuary tracks temperature closely: the first push comes as the shallows climb through the upper forties and fifties, the summer plateau sends the bigger fish to the deeper channel edges and the night tides, and the autumn cooling sets off the best fishing of the year as bait pours out of the marsh. Read the temperature, then fish the tide; the two together explain nearly everything that happens here.

Access

Stratford - the town at the river mouth, with launches, tackle and the most used shoreline access.
Nells Island - the marsh complex at the heart of the estuary and the gauge location.
Milford - the town on the east side of the mouth, with marinas and charter access.
Stratford Point - the shoreline access at the mouth, productive on the moving tide.
Derby - the head of tide upstream, where the estuary meets the river proper.
Long Island Sound - the open water beyond the mouth, with the bluefish and fluke fishing of the western Sound.
Short Beach - the Stratford shorefront access used by anglers working the bars on foot.

Seasons

Spring: the first striped bass push into the marsh and channel edges as the shallows warm, and winter flounder are available early.
Summer: steady and varied, with bluefish, fluke and scup joining the stripers and the night tides producing the larger bass.
Fall: the best fishing of the year, as bait leaves the marsh and stripers and bluefish feed hard on the outgoing tide.
Winter: cold and largely quiet, with the deeper holes holding fish and most of the estuary left alone until spring.
