Clear, low-algae water — summer clarity of 10.8 ft is clearer than most monitored Wisconsin lakes.
Based on July–August 2025 averages across 8 volunteer readings.39Oligotrophic5-yr summer TSI
Very clear, low-nutrient water — often deep, with limited plant growth.

Latest individual samples: Secchi 14.3 ft (2026-06-26), chlorophyll-a 1 µg/L (2026-06-22), and total phosphorus 12 µg/L (2024-08-26).
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 Little Cedar Lake?
Little Cedar Lake is 56 feet deep at its deepest point and averages about 13 feet, according to Wisconsin DNR records.
Is there a free depth map of Little Cedar Lake?
Yes. LakeList publishes a free interactive depth contour map of Little Cedar 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 Little Cedar 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.
