Every named reservoir in the Adirondack Park — flood-control basins, drinking-water sources, and the impoundments anchoring the southern watersheds.
Upper Reservoir is a five-acre impoundment in the Lake George region — small enough that most passing drivers wouldn't register it as a destination, functional enough that it sits on the map as a named water rather than a ditch with a gate valve. No fish data on file, no trail system radiating out from the shoreline, no camps or lean-tos in the DEC database. It's the kind of water that exists for infrastructure or private holdover purposes rather than recreation — a placeholder in the directory until someone who knows it better sends in the details.
