Every named reservoir in the Adirondack Park — flood-control basins, drinking-water sources, and the impoundments anchoring the southern watersheds.
Butler Storage Reservoir is a working 13-acre impoundment in the Lake George region — utility infrastructure, not backcountry destination. No public access points, no DEC presence, no fish stocking records in the system. It exists in that category of Adirondack waters that appear on the map but serve a function other than recreation: municipal supply, private hydropower, or in this case storage for a local water district. If you're compiling a list of named waters in the Park, Butler goes on it — if you're planning a paddling trip, keep scrolling.
