Historical volunteer-monitoring record for this lake.
Last sampled Sep 2020Volunteer monitoring 2019–2020
DNR volunteers monitored this lake for about 1 years, ending in 2020. In 2020 the water showed slight haze water (~6.5 ft Secchi), elevated algae (chlorophyll ~17.5 µg/L), and high nutrients (phosphorus ~72 µg/L). After 6 years without samples, these readings describe the lake as it was, not as it is.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2020 | 6.5 ft (2) | 17.5 µg/L (2) | 54.0 µg/L (1) |
| 2019 | 4.8 ft (2) | 17.0 µg/L (2) | 38.0 µg/L (1) |

Depth FAQ
How deep is Mauthe Lake?
Mauthe Lake is 23 feet deep at its deepest point and averages about 12 feet, according to Wisconsin DNR records.
Is there a free depth map of Mauthe Lake?
Yes. LakeList publishes a free interactive depth contour map of Mauthe 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 Mauthe 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.
