Historical volunteer-monitoring record for this lake.
Last sampled Sep 2018Volunteer monitoring 1993–2018
DNR volunteers monitored this lake for about 25 years, ending in 2018. Its final monitored summers showed slight haze water (~8.5 ft Secchi) in 2018, very low algae (chlorophyll ~2.5 µg/L) in 2018, and low nutrients (phosphorus ~16 µg/L) in 2017. After 8 years without samples, these readings describe the lake as it was, not as it is.

Depth FAQ
How deep is Rainbow Lake?
Rainbow Lake is 95 feet deep at its deepest point and averages about 37 feet, according to Wisconsin DNR records.
Is there a free depth map of Rainbow Lake?
Yes. LakeList publishes a free interactive depth contour map of Rainbow 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 Rainbow 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.
