Methodology

How this list is built

Ranked strictly by documented surface acres from DNR lake records.
Flowages and reservoirs count — they are lakes in the DNR's books, and some of the state's biggest water is impounded.
Lakes without documented acreage are excluded rather than estimated.
Lakes under 50 acres — or without documented acreage — are excluded from rankings.
Public access is shown for every lake but never affects the ranking.

Source data: Wisconsin DNR lake and monitoring records as aggregated by LakeList. Figures reflect the most recent documented values, not new surveys — verify access and rules before you go. Lake outlines are shoreline shapes from LakeList and the USGS National Hydrography Dataset; they illustrate a lake's form and are not depth or navigation charts.
