Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Falls Brook drains a small watershed in the Indian Lake township — one of dozens of minor tributaries feeding the Cedar River Flow system or flowing directly into Indian Lake itself. Without DEC fish surveys or documented access points, it exists in that middle register of Adirondack streams: named on the USGS quad, likely fishable for native brookies if you're willing to bushwhack, but absent from trail registers and campsite logs. In a region defined by bigger water — Indian Lake proper, the Cedar River corridor, the Moose River Plains — Falls Brook is the kind of stream you stumble across while heading somewhere else, note the name on the map, and keep moving.
