Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Allen Brook runs through the heart of Lake Placid village — not wilderness, but the kind of working stream that shapes a town's layout and drains a compact network of upland ponds and wetlands north of Mirror Lake. It flows under Main Street, cuts through residential blocks, and eventually feeds the Chubb River system before joining the Ausable watershed. No fish data on record, and no backcountry access to speak of — this is village infrastructure, not a paddling or fishing destination. If you're walking Main Street after a heavy rain, you'll hear it surging under the pavement.
