DNR water check
Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Jul 2015
The last DNR samples for this lake are from 2015, when the water showed very low algae (chlorophyll ~2 µg/L) and low nutrients (phosphorus ~12 µg/L). After 11 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 2024, but LakeList holds no readings after 2015 — check the station reports for anything newer.
