Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Notch Brook drains east into the Schroon Lake basin — a named tributary in the state gazetteer but not a water you'll find marked on most trail maps or mentioned in guidebooks. It likely carries seasonal flow from higher ground in the eastern Adirondacks, feeding into the broader Schroon watershed that eventually reaches the Hudson. Without documented access or fish data, this is cataloged water rather than destination water — the kind of stream that exists in the drainage network but sees more use by deer and seasonal paddlers than by anglers or hikers. If you know this brook by name, you're either studying hydrology or you own land along it.
