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.

Depth FAQ
How deep is Slim Lake?
Slim Lake is 42 feet deep at its deepest point and averages about 22 feet, according to Wisconsin DNR records.
Is there a free depth map of Slim Lake?
Yes. LakeList publishes a free interactive depth contour map of Slim Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Slim 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.
