Fish population survey
Structured LakeList extraction from the 2014 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 Delton (WBIC 1295400) only
Human-reviewed 2014 abundance, population, catch-rate, length, age and size-structure metrics for Lake Delton.
- Historical survey snapshot; not current regulations or navigation guidance.
- Only explicit fish-population observations and estimates were promoted; stocking rows, management targets, regulations and unsupported chart-only values were excluded.
- Metric source pages, survey years, methods, raw units and exact report-waterbody scope are retained.

Where does the Lake Delton 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.
