Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Ermine Brook runs through the Long Lake township in the central Adirondacks — a named tributary in a region where most flowing water either feeds Raquette River drainage or works its way toward the Forked Lake system. No public fish stocking records and no maintained trail access in the DEC inventory, which puts it in the category of seasonal drainage or local-knowledge water rather than a destination stream. The name suggests fur-trapping history — ermine (short-tailed weasel in winter coat) were prime pelts in the 19th-century Adirondack economy, and brooks often carried the names of what trappers pulled from the woods around them. If you're poking around the Long Lake backcountry and cross Ermine Brook, you're likely bushwhacking or on an unmarked logging trace.
