Methodology

How this list is built

Ranked strictly by documented maximum depth from DNR lake records. No estimates, no hearsay depths.
Lakes without a documented maximum depth are excluded rather than guessed at.
Lakes under 50 acres — or without documented acreage — are excluded from rankings.
Public access is shown for every lake but never affects the ranking — a deep lake ranks whether or not you can launch on it.
