Wisconsin · ranked by public data
Water quality leads this review. Summer algae carries the most weight, followed by beach advisories and closures, phosphorus and clarity. Beach experience matters, but cannot rescue weak or missing health evidence.
115 official DNR public-beach lakes reviewed. 8 clear the lake-level evidence gates; 7 have no occurrence found in the required swimmer's-itch sources. Evidence reviewed 2026-07-24.
Methodology · version 2026.07-v3
The score is deliberately health-first and fail-closed. Missing required evidence can exclude a lake; it is never treated as clean water or zero closures.
Modeled July–August water temperature is context only and earns zero points. The estimate is not a measured current temperature.
The evidence list
Top candidates are shown in detail; the remaining audited lakes are in the compact table.
Numeric statewide ranks remain unpublished. Only 7 lakes currently clear every evidence gate and the occurrence-free top-10 rule. Research scores are shown for comparison; an exclusion always overrides a score.

Always check official conditions on the day you swim. Notices may cover algae blooms, bacteria, spills, heavy rain, turbidity, dangerous currents, high water or local closures. A research score is not a live safety clearance.
Coverage and limits
The audit is complete, but only 7 lakes currently satisfy the stricter occurrence-free top-10 rule. LakeList will not fill the list with weaker evidence just to publish ten names.
No occurrence appeared for the exact lake or beach in the required sources checked through 2026-07-24. It does not prove an incident never happened.
Exact Beach Health site identity was resolved for 81 lakes, an exact DNR water-quality station for 64, and exact-beach advisory history for 81. Unresolved records remain visible but cannot rank.
Statewide cohort: Wisconsin DNR Find A Lake, Public Beach = Yes. Scores are LakeList's reproducible interpretation of cited public evidence, not a Wisconsin DNR endorsement.
