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 2015Volunteer monitoring 2001–2015
DNR volunteers monitored this lake for about 14 years, ending in 2015. Its final monitored summers showed murky water (~1.5 ft Secchi) in 2015, moderate algae (chlorophyll ~10 µg/L) in 2001, and moderate nutrients (phosphorus ~22 µg/L) in 2001. After 11 years without samples, these readings describe the lake as it was, not as it is.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2015 | 1.5 ft (1) | — | — |
| 2001 | 13.1 ft (1) | 10.0 µg/L (1) | 22.0 µg/L (1) |
