Seasonal estimate. Checking current National Weather Service air temperatures…
Warmest water of the year. Fish hold deeper or feed in low light; swimming and watersports are at their best.
Estimates are modeled, not measured. Actual temperatures vary with depth, wind mixing, and recent weather — verify conditions before swimming, boating, or heading onto ice.
Wisconsin DNR fisheries survey
Structured LakeList extraction from the 2025 DNR fisheries survey. Population estimates, density, and catch-rate indices use different units, methods, and scopes, so each value is presented in its original form rather than normalized against a different measure.
DNR captured 25 fish species. Smallmouth bass were the dominant sport fish, bluegill the dominant panfish, nongame redhorse and common carp dominated the assemblage, and northern-pike electrofishing catches remained an imperfect population index.
