Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
The Goodnow River drains northwest out of the Goodnow Flow — a damned pond on the south edge of the Santanoni Preserve — and winds through mixed hardwood and wetland before joining the Hudson River near the hamlet of Newcomb. It's a shallow, tea-colored flow through low country, more corridor than destination, threading between the High Peaks wilderness to the east and the open timber tract west of Long Lake. No designated access or formal put-ins on record, but sections of the river pass close to seasonal logging roads and cross under NY-28N south of Newcomb — primarily a route for through-paddlers connecting Goodnow Flow to the Hudson or for locals scouting beaver sign in spring. Brook trout likely present in the cooler headwater stretches, but the river itself stays off most fishing maps.
