Best bluegill lakes in Wisconsin
4075 Wisconsin waters hold bluegill, 148 mapped with real state-agency depth surveys. Ranked below by size and depth-data quality — open any water to see exactly where to fish it: depth contours, scored spots with plain-English reasons, seasonal windows and bait picks. The classic panfish. Shallow cover in summer, deeper weed edges otherwise.

What Wisconsin's 2026 forecast adds
Wisconsin DNR highlights Montello Lake after a spring electrofishing survey produced 349 bluegill per mile, a density above 90% of comparable Wisconsin lake surveys. Forty-four percent of captured fish were at least 6 inches and the largest measured 8.7 inches. The forecast also confirms one public boat launch. This current population evidence is useful, but it is separate from DepthScout's map ranking.

How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish bluegill in Wisconsin
- Spring 1–6 ft — Bedding colonies on sandy shallow flats — sight-fish the light spots.
- Summer 4–15 ft — Weed edges and dock shade; bigger 'gills hold slightly deeper.
- Fall 6–18 ft — Schools tighten on remaining green weeds and first drops.
- Winter 10–25 ft — Soft-bottom basins with invertebrates; finesse presentations.
