Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
East Inlet feeds the eastern shore of Fourth Lake in the Fulton Chain — a small tributary system that drains the forested slope between Inlet and the lake's main basin. The stream runs quick and cold in spring, dropping through a series of shallow cascades before flattening into the lake near the Eagle Bay shoreline. It's the kind of connector water that fly anglers scout during brook trout season and paddlers notice as a landmark when navigating the north arm of Fourth Lake. No formal access points or trails follow the inlet, but it's visible from the water and marks the transition from the open lake to the quieter coves that buffer the channel route toward Fifth Lake.
