Every named river in the Adirondack Park — the Hudson, the Moose, the Raquette, the Sacandaga, and the rivers that drain the High Peaks.
Lake Lonely Outlet drains Lake Lonely — a small, relatively quiet lake north of Saratoga Springs — into the Great Sacandaga Lake reservoir system. The outlet itself is more of a connector stream than a destination, flowing through low-lying wetland and residential patches before joining the reservoir's northern reaches. No formal access points or public launch infrastructure on the outlet proper; paddlers who want to fish or explore this water typically launch from Lake Lonely itself and work downstream. Species data is sparse, but the outlet likely holds whatever warm-water residents (perch, pickerel, bass) move between the lake and the reservoir depending on season and water level.
