Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
The West Branch Ausable is New York's most celebrated trout stream, holding brown, rainbow, and brook trout under catch-and-release regulations in its managed stretches. Technical water that demands wading skill and artificial-lure discipline — this is an advanced fishery, not a learning ground.
The West Branch Ausable River runs north from the High Peaks through Lake Placid village, paralleling NY-86 and Wilmington Notch Road before joining the East Branch downstream near Au Sable Forks. It's the drainage for the northwest face of the range — everything coming off Whiteface, Esther, and the back side of Cascade pours into this corridor — and the flow moves fast after rain or snowmelt. The river runs through town, under bridges, past the Olympic ski jumps, accessible but not wild until you're upstream of the village or deep into the notch. Kayakers and anglers know the West Branch as a cold-water system; rafters wait for spring runoff and head for the lower gorge sections.
The West Branch Ausable River drains the northwest flank of the High Peaks — fed by tributary streams off Marcy, Colden, and the MacIntyre Range — and meets the East Branch at Ausable Forks to form the main stem that cuts north toward Lake Champlain. It's a whitewater river in spring, a boulder-garden trout stream by midsummer, and the primary drainage for the Lake Placid / Wilmington corridor. Access is scattered: Old Military Road parallels stretches of the upper river south of Lake Placid, and Wilmington Notch offers roadside pull-offs where NY-86 shadows the water downstream. Anglers work the pocket water for brookies and browns; kayakers scout the Wilmington section in May.
The West Branch Ausable River drains the northwestern High Peaks — most notably the slopes of Whiteface, Esther, and the Sentinel Range — before meeting the East Branch downstream near Ausable Forks. Above Lake Placid the river runs cold and tight through boreal forest, accessible primarily via the Whiteface Mountain Memorial Highway corridor and Wilmington Notch; below the village it widens and warms as it bends north through farmland and second-growth hardwoods. The West Branch sees consistent stocking and natural reproduction of brook and brown trout, with the upper stretches holding wild brookies in the pocket water above Highway drops. Spring runoff turns the river into a churning freight train by mid-April; by late June it's wadeable and fishable again.
