DNR water check
Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Aug 1985
The last DNR samples for this lake are from 1985, when the water showed hazy water (~5.9 ft Secchi), elevated algae (chlorophyll ~13 µg/L), and low nutrients (phosphorus ~16 µg/L). After 41 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 1986, but LakeList holds no readings after 1985 — check the station reports for anything newer.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
