Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
The Schroon River drains north from Schroon Lake through the town of Schroon Lake and eventually feeds the Hudson River near Warrensburg — a long, meandering corridor that defines the eastern edge of the Adirondack Park's lake country. Most paddlers know the river for its Class I–II spring runs below the lake outlet, accessible from several informal put-ins along US-9, though summer flows drop and turn the river into a shallow, rocky meander better suited to wading than boating. The stretch between Schroon Lake village and Riverbank is largely undeveloped and passes through mixed hardwood flats — quiet water when the lake gets crowded, and a decent bet for smallmouth bass in the deeper pools. Check flow levels before committing to a paddle; by August it's more creek than river.
