Depth FAQ
How deep is Julia Lake?
Julia Lake is 45 feet deep at its deepest point and averages about 18 feet, according to Wisconsin DNR records.
Is there a free depth map of Julia Lake?
Yes. LakeList publishes a free interactive depth contour map of Julia Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Julia Lake 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.
