Wisconsin DNR fisheries survey
Fish population 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.
Survey indicatorsValues keep their source unit and method; unlike measures are not scaled or compared.
Management contextLake-specific late-spring whole-shoreline electrofishing across 1.95 miles.
DNR found moderate bluegill abundance, moderate-high largemouth-bass abundance with improved size structure and a modest pumpkinseed sample.
- The pumpkinseed table prints stock-size CPUE as 66 fish/mile, which cannot reconcile with a 20-fish catch over 1.95 miles; that value is excluded rather than corrected.
- Historical 2015 values and 2026-27 regulations are excluded.
- The next early-spring electrofishing survey is explicitly scheduled for 2034.

Depth FAQ
How deep is South Harper Lake?
South Harper Lake is 32 feet deep at its deepest point and averages about 11 feet, according to Wisconsin DNR records.
Is there a free depth map of South Harper Lake?
Yes. LakeList publishes a free interactive depth contour map of South Harper Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the South Harper 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.
