Latest individual samples: Secchi 7 ft (2025-08-10), chlorophyll-a 4 µg/L (2026-06-13), and total phosphorus 15 µg/L (2023-07-21).
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 Lake of the Pines?
Lake of the Pines is 39 feet deep at its deepest point and averages about 17 feet, according to Wisconsin DNR records.
Is there a free depth map of Lake of the Pines?
Yes. LakeList publishes a free interactive depth contour map of Lake of the Pines 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 Lake of the Pines 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.
