Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
The Great Chazy River drains north through Clinton County from its source near Lyon Mountain, cutting through farmland and forest before crossing into Quebec and emptying into Lake Champlain — one of the longer north-flowing systems in the northeastern Adirondacks. The upper stretches run through state forest land with seasonal trout fishing; the lower river opens up into agricultural corridor with roadside access off a patchwork of county routes. It's a working river more than a destination paddle — moderate gradient, occasional beaver work, and enough public road crossings to make it a decent day trip for anglers who know the stocking schedule. Spring runoff brings the best flows; by August it runs shallow and warm below the headwaters.
