Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
The Poultney River runs along the western edge of the Adirondack Park boundary in the Brant Lake region — more drainage corridor than destination water, and one of the quieter flows in a district better known for its lakes. It marks a transition zone: east toward the core lake country, west toward farmland and the Vermont line. No official fish data on record, but small Adirondack tributaries in this drainage class typically hold wild brook trout in the headwater stretches if the gradient and canopy are right. Access depends on town roads and private landholdings; check with the town clerk or local anglers before assuming you can walk in.
