This is a smooth mathematical model, not a survey - real holes, bars, and drop-offs will differ. Community sonar (C-MAP Genesis) overlays where recorded. Not for navigation.LakeList assistant

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2012 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 contextRainbow Flowage (WBIC 1595300) only
Human-reviewed catch, CPUE, population, length and size-structure metrics for exact Rainbow Flowage.
- Historical survey snapshot; not current regulations or navigation guidance.
- Stocking histories, regulations, creel/angler-use metrics, recommendations, comparison-water values and unsupported chart-only values were excluded.

Depth FAQ
How deep is Rainbow Flowage?
Rainbow Flowage is 28 feet deep at its deepest point, according to Wisconsin DNR records.
Is there a free depth map of Rainbow Flowage?
Yes. LakeList publishes a free interactive depth contour map of Rainbow Flowage at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Rainbow Flowage 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.
