Methodology

How this list is built

Ranked by the official maximum depth in Minnesota DNR LakeFinder records; where none is published, the deepest mapped contour from MN DNR survey bathymetry stands in (contours can slightly understate depth, never overstate it).
Only lakes with published Minnesota DNR survey bathymetry on LakeList can rank (about 1,500 lakes). Deep border waters without a published DNR depth record — Saganaga Lake among them — are not listed rather than guessed at.
Lakes under 50 acres — or without a confidently matched USGS NHD polygon for acreage — are excluded from rankings.
Public access inventories are not yet tracked for Minnesota here, so access is never shown or ranked.
