Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Kelso Brook runs through the Schroon Lake region — a tributary water in a part of the Park better known for its lakefront villages and summer camps than its backcountry streams. Without stocked fish or mapped trail access, it's the kind of brook that appears on the quad but stays off most paddlers' and anglers' radars. These minor tributaries do their work quietly: they feed the larger watersheds, hold native brookies in their headwater stretches when conditions allow, and occasionally turn up as bushwhack reference points for hunters and winter trackers. Check DEC stream corridor easements if you're planning to explore it on foot.
