Little Thunder Flowage Fishing Map — 3 ft Deep, Spots (WI)

Target species

Species from state lake data, resolved by location. These species come from the Wisconsin DNR's own per-lake fish listing. Where the DNR reports a group rather than a species — “panfish”, “catfish”, “trout” — the specific species are resolved from Wisconsin's fish distribution by this lake's location, depth and habitat, so those are an informed estimate, not a per-species survey. The named gamefish (walleye, musky, bass, pike, sturgeon…) are the DNR's own listing. (The depth chart is a computer-generated estimate from the lake's real shoreline and the DNR's maximum depth — not measured contours.) How we estimate species →

Recommendations come from depth structure and seasonal species behavior. Treat them as a starting point, not a guarantee. Contours on this water are approximations. Never use for navigation. Always check local regulations.
