Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2024 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 2024 comprehensive early- and late-spring multi-gear assessment; each count, CPUE, size sample and population estimate retains its printed gear, cohort and uncertainty scope.
DNR documented high largemouth-bass abundance, excellent bluegill/yellow-perch size and growth, and an estimated 319 mature northern pike with exceptional size structure.
- The bluegill narrative total conflicts with the all-gear table; no total bluegill catch is promoted.
- The walleye narrative says three fish while the all-gear table says four; no walleye count or derived metric is promoted.
- The brown-trout electrofishing CPUE conflicts between narrative and table; only the coherent early-net CPUE is retained.
- Historical comparisons, creel estimates, stocking history, objectives and figure-only age values are excluded.

Depth FAQ
How deep is Devils Lake?
Devils Lake is 47 feet deep at its deepest point and averages about 30 feet, according to Wisconsin DNR records.
Is there a free depth map of Devils Lake?
Yes. LakeList publishes a free interactive depth contour map of Devils Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Devils Lake depth map come from?
The interactive depth contours are derived from LakeList depth model. Each contour set passes a visual QA review against the source document before it is published. The depths are a modeled estimate calibrated to the lake's documented maximum depth - not a survey, and not for navigation.
