Depth FAQ
How deep is Loon Lake?
Loon Lake is 9 feet deep at its deepest point, according to Wisconsin DNR records.
Is there a free depth map of Loon Lake?

Where does the Loon 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.
