About this Water
- Tailwater
- Best months: Year-round; peak May–June and Sept–Nov
The Farmington River in northwestern Connecticut is New England's premier tailwater trout fishery — cold releases from Otis and West Branch dams support a wild brown trout fishery in what would otherwise be a Connecticut River tributary too warm to hold trout. The Permanent Trout Management Area (PTMA) from Riverton through New Hartford offers the highest-quality water: catch-and-release wild browns, technical hatch fishing, and consistent year-round conditions. Hendrickson and Sulphur emergences define the spring/early-summer dry-fly calendar. Tricos through August offer the most demanding small-fly fishing in the East.
The Farmington's PTMA section produces wild brown trout densities estimated at over 2,000 fish per mile — the highest documented for any Connecticut river and competitive with the East's most famous tailwaters.
January Outlook
January on the Farmington River tailwater — the Barkhamsted Reservoir release keeps the river open and fishable year-round. Midge and Baetis nymph fishing in the catch-and-release section near New Hartford produces brown trout through Connecticut winter.
Productive Patterns
- Zebra Midge
- Baetis Nymph
- RS2
- Soft Hackle Midge
Tips
The Farmington's tailwater character is its greatest asset in winter. The reservoir release keeps water temperatures consistent and the river open. Midge nymphing in the slower pools of the C&R section produces consistent winter brown trout. One of New England's best winter tailwaters.
Water Notes
Regulated flows 200–400 cfs from Barkhamsted Reservoir. Water 44–50°F. Open all year. Winter midge fishing excellent.
February Outlook
February tailwater fishing on the Farmington. The regulated release from Barkhamsted Reservoir keeps the river from freezing and maintains consistent fishing conditions. Midge hatches on mild afternoons.
Productive Patterns
- Zebra Midge
- RS2
- Baetis Nymph
- WD-40
Tips
February is quiet on the Farmington but productive for winter midge specialists. The C&R section above New Hartford provides the best access. Fish the seams and pools near the tailout sections where midges concentrate.
Water Notes
200–400 cfs. Water 44–50°F. Regulated tailwater. One of CT's few winter fishing options.
March Outlook
March brings early Baetis hatches to the Farmington as New England slowly warms. The tailwater keeps conditions ahead of the freestone streams. Early risers appear by mid-month in favorable years.
Productive Patterns
- Blue Winged Olive
- Baetis Nymph
- Zebra Midge
- Soft Hackle Emerger
Tips
March on the Farmington is the transition from winter to spring. Early Baetis hatches begin by mid-March in mild years. The tailwater section fishes weeks earlier than surrounding freestone rivers. A great early-season destination.
Water Notes
250–500 cfs. Water 46–52°F. Early Baetis activity beginning. Tailwater advantage over freestone rivers.
