From Wisconsin DNR / Citizen Lake Monitoring readings at Shawano Lake - Deep Hole.
Sampled Jun 2026Volunteer monitoring since 1988
Somewhat hazy water — summer clarity of 6.5 ft is lower than most monitored Wisconsin lakes.
Based on July–August volunteer averages from 2021–2025; each value shows its own year.54Eutrophic5-yr summer TSI
Nutrient-rich, greener water — more algae and plant growth, common in shallower lakes.

Latest individual samples: Secchi 8 ft (2026-06-20), chlorophyll-a 2 µg/L (2026-05-26), and total phosphorus 32 µg/L (2023-07-19).
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 Shawano Lake?
Shawano Lake is 40 feet deep at its deepest point and averages about 9 feet, according to Wisconsin DNR records.
Is there a free depth map of Shawano Lake?
Yes. LakeList publishes a free interactive depth contour map of Shawano 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 Shawano 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.
