Historical volunteer-monitoring record for this lake.
Last sampled Jul 2024Volunteer monitoring 1992–2024
DNR volunteers monitored this lake for about 32 years, ending in 2024. Its final monitored summers showed crystal clear water (~20 ft Secchi) in 2018, very low algae (chlorophyll ~1.5 µg/L) in 1997, and very low nutrients (phosphorus ~9 µg/L) in 2012. After 2 years without samples, these readings describe the lake as it was, not as it is.

Depth FAQ
How deep is Katherine Lake?
Katherine Lake is 30 feet deep at its deepest point and averages about 16 feet, according to Wisconsin DNR records.
Is there a free depth map of Katherine Lake?
Yes. LakeList publishes a free interactive depth contour map of Katherine 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 Katherine 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.
