Methodology

How this list is built

  • 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.
  • Reservoirs count — most of Indiana's biggest water is impounded (Monroe, Patoka, Brookville).
  • Lake Michigan is excluded — this list ranks inland lakes.
  • 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 Indiana here, so access is never shown or ranked.
