The 25 Biggest Lakes in New York

• Ranked by surface area computed from USGS National Hydrography Dataset (NHD) lake polygons — consistent federal geometry, not state-documented acreage; figures can differ modestly from traditionally cited ones.
• The Great Lakes and Lake Champlain are excluded — Champlain spans New York, Vermont, and Québec, so its full surface would overstate a New York ranking.
• Lakes whose mapped polygon could not be confidently matched are excluded rather than guessed.
• Lakes under 50 acres are excluded from rankings.
• Public access inventories are not yet tracked for New York here, so access is never shown or ranked.

Every number on this page comes from the same public agency records that power each lake's profile, and the list is recomputed as that data updates — it cannot silently go stale the way a hand-written top-10 does.
