Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2023 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.
Survey indicatorsValues keep their source unit and method; unlike measures are not scaled or compared.
Management contextLake-specific May 2023 survey using 20 fyke-net nights and four miles of electrofishing. Every metric remains a relative-abundance or sample size-structure observation.
DNR documented high walleye, northern-pike, largemouth-bass, black-crappie and bluegill catch rates, good walleye and muskellunge size structure, and generally small panfish.
- Sparse raster figure pages 2-3 are retained in the hash-verified source but are not used for promoted values; every metric comes from page-numbered narrative on pages 4-6.
- No fish counts or whole-water abundance values are derived from rounded CPUE and effort.
- Weather and moving ice forced crews to relocate several nets; source CPUE values are retained as printed.

Depth FAQ
How deep is Lost Land Lake?
Lost Land Lake is 21 feet deep at its deepest point and averages about 12 feet, according to Wisconsin DNR records.
Is there a free depth map of Lost Land Lake?
Yes. LakeList publishes a free interactive depth contour map of Lost Land Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Lost Land Lake depth map come from?
The interactive depth contours are derived from C-MAP Genesis community sonar (derived). Each contour set passes a visual QA review against the source document before it is published. The depths are derived from community sonar recordings (C-MAP Genesis Social Map, used with permission), with gaps between recordings interpolated; not for navigation.
