The Housatonic River, known to regulars as the Housy, flows south from the Berkshire Hills of Massachusetts through the limestone valleys of Litchfield County, Connecticut before eventually reaching Long Island Sound. The 10.4-mile Trout Management Area between Falls Village and Cornwall Bridge draws fly anglers from across the Northeast and is widely regarded as one of the finest trout streams in the eastern United States. The river is large enough to fish effectively from a drift boat, a quality that sets it apart from most eastern trout water and gives it a feel that locals compare to the big freestone rivers of Montana and Idaho. Deep pools, long riffles, pocket water, and limestone bluffs alternate through the valley, holding concentrations of brown and rainbow trout in the 14 to 18 inch range, with larger fish present throughout the catch-and-release sections.
May through mid-June is the prime window on the Housy, when Hendricksons, March Browns, Grey Fox, Brown Drakes, Sulphurs, and the famous blizzard caddis hatch overlap to produce some of the best dry fly fishing in New England. The TMA is open to trout fishing year-round, but summer temperatures regularly push above 70 degrees Fahrenheit from July through mid-September. Responsible anglers avoid targeting trout in warm water and focus on early morning sessions or switch to the river's excellent smallmouth bass fishery during hot afternoons. When temperatures drop back into the 60s in September, fall fishing can be outstanding through November, with the Isonychia hatch in September and October being one of the best dry fly events of the season. The White Fly and Alder Fly, two hatches rarely found on other Connecticut streams, produce spectacular surface action through October and November.
Brown and rainbow trout are the primary species throughout the TMA, with 9,000 fish stocked in spring averaging 8 to 17 inches and another 9,000 stocked each fall. Holdover fish from previous stockings grow to 18 inches and beyond, and the river produces a regular catch of 20-plus inch fish for anglers who know where to look. Brook trout occasionally appear near the cold tributary streams that enter the main river. During the summer closure, the Housatonic becomes one of Connecticut's best smallmouth bass fisheries, and a growing population of northern pike to 42 inches inhabits the slower, deeper sections downstream of the TMA.
The upper TMA is accessible throughout its length via Route 7 on the west bank and River Road on the east bank, with numerous pullouts and the Housatonic Meadows State Park campground providing base camp access. The lower three miles from Dun Rollin Pool to the Route 4 bridge are fly fishing only. The lower TMA at Bulls Bridge has limited access from Route 7 pullouts. The TMA is open to trout fishing year-round, and all trout must be caught and released throughout both TMA sections. The June 15 to September 15 closure applies only to thermal refuge areas within 100 feet of posted signs at specific tributary mouths, specifically Kent Falls Brook and Macedonia Brook, where trout congregate to escape warm water. Fishing is prohibited in these posted thermal refuges during that period. Spiked boots or studded wading sandals are strongly recommended on the river's slippery limestone bottom. A Connecticut fishing license is required for all anglers 16 and older.
The Housatonic River is a dam-influenced freestone stream. Flows were historically subject to unpredictable daily fluctuations from hydroelectric releases at the Falls Village Dam, but the river now runs at more natural levels. Checking current flow before any trip remains important, as flows above 600 CFS make wading the TMA difficult. Most anglers find the river most productive when flows are running below 400 CFS. Always check water temperature before fishing in spring and early summer, as temperatures approaching 68 degrees Fahrenheit signal stress conditions for trout and responsible anglers will stop fishing and wait for cooler conditions.
