Upper TMA — Route 318 Bridge to Route 219 Bridge
The Upper Trout Management Area is the crown jewel of Farmington River fishing — a 3.5-mile flies-only catch-and-release stretch that begins roughly a mile above the Route 318 Bridge in Riverton and runs downstream to the Route 219 Bridge in New Hartford. This is the section that most serious fly anglers travel to fish, with holdover brown trout that have seen every pattern and demand precise presentations. The TU has documented trout densities here that rival some western tailwaters. The bottom-draw release from Colebrook Reservoir keeps water temperatures consistently in the 50s year-round, suppressing summer heat and preventing winter freeze. Access via Route 44 with multiple pull-offs and a riverside trail system.
💧 Ideal flow: 150 to 400 CFS for comfortable wading and dry fly presentation. The river becomes more difficult to wade above 500 CFS. Check the Riverton gauge before making the drive — flows are generally stable but can fluctuate after significant rain events in the watershed.

Lower TMA — New Hartford Catch and Release Section
The Lower TMA below Route 219 offers additional catch-and-release water with somewhat less pressure than the upper section. The river here has a slightly different character — wider in places with longer flats that demand stealthy presentations and longer leaders. The Still River enters just downstream and the confluence area is worth targeting as the mixing of temperatures can concentrate fish. This section has excellent access along the Farmington River Trail. The lower TMA allows two trout per day outside of the C&R boundary — check current regulations carefully as they vary by section.
💧 Ideal flow: similar to the upper section, 150 to 400 CFS fishes well. The lower river is slightly more forgiving at higher flows due to the wider character but the flat water sections require low and clear conditions for dry fly success.

Riverton — Below Goodwin Dam
The first mile below Goodwin Dam in Riverton is classic deep tailwater — cold, consistent flows and the highest holdover trout density on the river. This stretch sees more pressure than the TMA sections due to easy access from the village of Riverton but rewards early morning visits when fishing can be exceptional. The pocket water immediately below the dam holds fish year-round. The Farmington River Anglers Association maintains this section and has invested heavily in habitat improvement.
💧 Ideal flow: this section fishes across a wider range than the TMA due to the deeper character. Good fishing from 100 CFS to 600 CFS. Winter midge fishing is consistent here even at low flows when the TMA sections are technical.

About Farmington River Fishing
The West Branch of the Farmington River is the most celebrated trout fishery in Connecticut and one of the finest tailwater fisheries in the entire Northeast. Cold bottom-draw releases from Colebrook Reservoir keep the river in the 50-degree range year-round, creating ideal trout habitat through Riverton, Pleasant Valley, and New Hartford. Trout Unlimited has documented population densities in the Trout Management Areas that rival some western Blue Ribbon streams — an extraordinary achievement for a river less than two hours from midtown Manhattan. The river draws anglers from across the Northeast and mid-Atlantic who know that the combination of cold stable tailwater, abundant insect life, and selective pressured fish makes the Farmington one of the most technically demanding and rewarding trout rivers on the East Coast.
Best Time to Fish Farmington River
Year-round fishing in the Trout Management Areas. Early season from February through April produces consistent midge and BWO activity with large holdover browns available in the deep pools. The Hendrickson hatch in late April and May is the signature spring event — one of the most prolific in the Northeast on this river. Sulphur hatches from late May through June bring fish to the surface in reliable evening sessions. Summer is surprisingly productive given the cold tailwater — terrestrial fishing with ants and beetles is excellent through July and August when most other Northeast rivers are too warm. September and October bring Isonychia and fall BWO hatches. Winter midge fishing on the lower river is consistent through December and January.
Species
Wild and holdover brown trout dominate the TMA sections — fish that have survived multiple seasons develop exceptional selectivity and average significantly larger than stocked fish. Rainbow trout are also present and some sections receive stocking outside the TMA boundaries. Brook trout exist in smaller numbers in the upper tributaries. The holdover browns in the Riverton section grow to 20 inches and larger. The river is stocked from April through October in non-TMA sections with a standard trout season.
Access and Regulations
Upper TMA: Route 318 Bridge to Route 219 Bridge — flies only, catch and release, year-round. Lower TMA: varies by section, check current regulations. Non-TMA sections receive stocking with standard harvest regulations. Connecticut fishing license required. The Farmington River Trail provides excellent walking access throughout the best water. Multiple parking areas off Route 44 in Riverton and New Hartford.
Live River Data
Streamflow data is pulled in real time from the USGS National Water Information System. The Farmington River runs on relatively stable bottom-draw reservoir releases. The Riverton gauge provides upstream conditions and the Unionville gauge provides downstream readings. Check both before planning a trip to understand the full picture of conditions through the TMA sections.
