Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Hague Brook drains a quiet fold of forest in the Brant Lake region — not a destination stream, but the kind of wooded tributary that feeds the watershed without much fanfare. No stocked fish, no marked trailheads, no lean-tos in the immediate corridor; it's backcountry by virtue of being neither accessed nor promoted. The brook likely holds wild brookies in its headwater stretches if the gradient and cover are right, but you'd be fishing on intuition and bushwhack rather than any published beta. Best known, if at all, as a line on the topo between nearby ponds and the hamlet of Hague to the east.
