About Farmington River (West Branch)
The West Branch of the Farmington is the best trout river in Connecticut and one of the few genuine tailwaters in New England. Cold water pulled from the base of Goodwin Dam — locals call it Hogback — keeps the reach below Riverton in the 50s all summer while the rest of the state's freestone rivers cook. On a mid-July afternoon the Riverton gauge was reading discharge in the low 100s CFS at roughly 49°F. That thermal refuge, plus a Trout Management Area established in 1988, is why the water from Riverton down through New Hartford holds the densest trout population in the state, including a genuine population of stream-bred wild browns mixed with holdovers that push past 20 inches.
It fishes as a technical dry-fly and tight-line river, not a chuck-and-duck freestone. Classic flat pools — Church Pool, the Boneyard, Greenwoods — sit between riffles and pockets, and the trout in them see enough pressure to get fussy about drift and tippet. This is one of the best-known Euro-nymphing rivers in the Northeast: a jig nymph or jig streamer on a tight-line rig is the default way most anglers pick apart the pocket water, while the pools reward long leaders and light presentations during a hatch. It's a wading river top to bottom — no float traffic in the TMAs — and hatches are the whole point. Hendricksons and red quills come in late April, a long sulphur run stretches from mid-May into late June, caddis carry through the summer, and tricos and white drakes (Isonychia included) run into August. Midges matter every single day, especially in the dead stretches between mayfly hatches.
The catch is that the tailwater is only as cold as the dam lets it be. Colebrook River Lake upstream and West Branch Reservoir at Goodwin drive the releases, and in a low-water year or a hot spell the reach warms enough that anglers carry a thermometer and stop fishing when it climbs toward the low 70s. Access is excellent and well-signed off Routes 20 and 44 through Peoples State Forest and Pleasant Valley, which also means crowds on a good hatch weekend. Below the confluence with the East Branch, the mainstem at Collinsville and Unionville warms fast and shifts toward holdover trout and smallmouth by midsummer — the cold-water fishery is really the West Branch above New Hartford.
