Latest individual samples: Secchi 25 ft (2026-06-26), chlorophyll-a 1 µg/L (2025-08-27), and total phosphorus 10 µg/L (2023-08-23).
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 Blue Lake?
Blue Lake is 49 feet deep at its deepest point and averages about 25 feet, according to Wisconsin DNR records.
Is there a free depth map of Blue Lake?
Yes. LakeList publishes a free interactive depth contour map of Blue Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Blue 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.
