Summer averages (July/August)
July/August means; counts in parentheses show how many samples went into each average.

Latest individual samples: Secchi 11 ft (2024-10-19).
Secchi clarity is how deep a black-and-white disk stays visible from the surface — more feet means clearer water.
Chlorophyll-a is an algae pigment; higher values signal more algae in the water column.
Total phosphorus is a nutrient that feeds algae and aquatic plants. It is not a weed survey — depth, bottom type, water movement, and management change the actual lake experience.

Depth FAQ
How deep is Fence Lake?
Fence Lake is 86 feet deep at its deepest point and averages about 37 feet, according to Wisconsin DNR records.
Is there a free depth map of Fence Lake?
Yes. LakeList publishes a free interactive depth contour map of Fence Lake at a typical 10-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Fence 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.
