From Wisconsin DNR / Citizen Lake Monitoring readings at Connors Lake - Deepest Spot.
Sampled Jun 2026Volunteer monitoring since 2007
Clear, low-algae water — summer clarity of 11.4 ft puts it among the clearest quarter of monitored Wisconsin lakes.
Based on July–August volunteer averages from 2023–2025; each value shows its own year.42Mesotrophic5-yr summer TSI

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 Connors Lake?
Connors Lake is 82 feet deep at its deepest point and averages about 38 feet, according to Wisconsin DNR records.
Is there a free depth map of Connors Lake?
Yes. LakeList publishes a free interactive depth contour map of Connors Lake at a typical 10-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Connors 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.
