Every named reservoir in the Adirondack Park — flood-control basins, drinking-water sources, and the impoundments anchoring the southern watersheds.
Patterson Reservoir is a 35-acre impoundment in the town of Keene — municipal infrastructure, not backcountry destination. The reservoir serves as a local water supply, which typically means restricted access and no recreational use, though some ADK reservoirs allow seasonal fishing or shoreline hiking under posted rules. Without species data on file and no nearby trailheads or peaks within easy reach, this one sits firmly in the "pass-through view from the road" category. Check with the Town of Keene for current access policies if you're curious; most small municipal reservoirs in the Park keep a low profile by design.
