About Winooski River
The Winooski is northern Vermont's big-river trout fishery, and one of the few trout streams in the state you can walk to from a downtown sidewalk. It runs roughly 90 miles from Cabot down through Montpelier and Waterbury to Lake Champlain at Burlington, but the productive fly water is the freestone middle — about 50 miles from the reaches around Marshfield and Plainfield down to Richmond, where it slows and warms into a smallmouth river. Through Montpelier and Waterbury it's a 50-to-80-foot-wide freestone stream of riffles, runs, and pools over gravel and cobble — not technical spring-creek water, but honest wading water that rewards a nymph rig most of the season. Wild and stocked brown trout and rainbow trout hold the upper and middle reaches, and the state drops two-year-old fish and broodstock into the Waterbury trophy stretch, so a 16-to-22-inch fish is a real possibility (and a 26-incher isn't a fantasy) — though these are put-grow-take stockers, not a wild trophy population.
Below the Huntington confluence the river becomes a genuinely different fishery: smallmouth bass, fallfish, and carp take over, with a fall run of landlocked salmon and steelhead pushing in out of Lake Champlain to the well-known Salmon Hole below the Winooski One dam. You can fish trout near Montpelier in the morning and swing streamers for smallmouth near Richmond the same afternoon. The honest catch is temperature, not low water: the middle and lower river runs warm through summer and regularly tops 70 degrees by mid-July, so the trout fishing is really a late-May-through-late-June and a mid-September-through-mid-October game, with August fishable only when a cool spell drops water temps back into the 60s. Flows swing hard on a snowmelt regime — big and off-color in April, thin by August.
One practical note on reading the water: the two USGS gauges tell very different stories. The Essex Junction gauge (04290500) sits low in the system with a 1,044-square-mile drainage and reads far higher than the fishable trout reaches upstream — everyday summer flow there runs 700 to 1,050 CFS. Use the Montpelier gauge (04286000) as your reference for the wadeable trout water, where roughly 150 to 400 CFS is comfortable wading. Access is the river's quiet strength: state and town fishing-access areas at Montpelier, Waterbury, Bolton, Richmond, and Colchester Point put you on the water with parking, and Route 2 and River Road shadow the river for miles. The dams through the corridor — Winooski One, Bolton, Middlesex — are run-of-river hydro operated by Green Mountain Power, so they shape access and character but don't stage the flow the way a storage dam would.
