From Wisconsin DNR / Citizen Lake Monitoring readings at Harris Lake - Center- Main Body Of Lake.
Last sampled Aug 2025Volunteer monitoring since 1991
Through 2025, very clear, low-algae water — summer clarity of 16.1 ft puts it among the clearest tenth of monitored Wisconsin lakes.
Based on July–August volunteer averages from 2023–2025; each value shows its own year.40Oligotrophic5-yr summer TSI
Very clear, low-nutrient water — often deep, with limited plant growth.

Latest individual samples: Secchi 18 ft (2023-08-27), chlorophyll-a 1 µg/L (2025-08-30), and total phosphorus 14 µg/L (2018-06-20).
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 Harris Lake?
Harris Lake is 57 feet deep at its deepest point and averages about 24 feet, according to Wisconsin DNR records.
Is there a free depth map of Harris Lake?
Yes. LakeList publishes a free interactive depth contour map of Harris 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 Harris 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.
