This is a smooth mathematical model, not a survey - real holes, bars, and drop-offs will differ. Community sonar (C-MAP Genesis) overlays where recorded. Not for navigation.LakeList assistant

Historical volunteer-monitoring record for this lake.
Last sampled Aug 1992Volunteer monitoring 1974–1992
DNR volunteers monitored this lake for about 18 years, ending in 1992. In 1992 the water showed murky water (~2.7 ft Secchi), elevated algae (chlorophyll ~16.7 µg/L), and elevated nutrients (phosphorus ~42.7 µg/L). After 34 years without samples, these readings describe the lake as it was, not as it is.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 1992 | 2.7 ft (3) | 16.7 µg/L (3) | 42.7 µg/L (3) |
| 1974 | — | — | 40.0 µg/L (1) |

Depth FAQ
How deep is Sherwood Lake?
Sherwood Lake is 9 feet deep at its deepest point and averages about 3 feet, according to Wisconsin DNR records.
Is there a free depth map of Sherwood Lake?
Yes. LakeList publishes a free interactive depth contour map of Sherwood Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Sherwood Lake depth map come from?
The interactive depth contours are derived from LakeList depth model. Each contour set passes a visual QA review against the source document before it is published. The depths are a modeled estimate calibrated to the lake's documented maximum depth - not a survey, and not for navigation.
