Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
Newcomb River drains the southwestern corner of the High Peaks Wilderness — a dark-water flow that runs north from the outlet of Lake Harris through a forested corridor before joining the Hudson River near the hamlet of Newcomb. The river sees light paddling traffic in the spring when flows are up, but it's mostly a thoroughfare for anglers working the pools and riffles between the lake and the confluence. The shoreline is state land for most of its length, with access tied to the back roads and informal pull-offs that skirt the flow rather than any maintained trailhead. It's quiet water in a working corner of the park — more transit than destination.
Newcomb River drains northeast out of Harris Lake and Rich Lake, flowing roughly parallel to NY-28N through the town of Newcomb before joining the Hudson River near the hamlet. It's a quiet, meandering run through mixed hardwood and conifer — more of a working drainage than a destination river, though paddlers occasionally float sections in high water during spring runoff. The river corridor is undeveloped for most of its length, passing through a mix of state land and private forest holdings. Access is limited to road crossings and informal put-ins where the highway comes close to the water.
