Historical volunteer-monitoring record for this lake.
Last sampled Sep 2020Volunteer monitoring 2013–2020
DNR volunteers monitored this lake for about 7 years, ending in 2020. Its final monitored summers showed crystal clear water (~16.5 ft Secchi) in 2020, low algae (chlorophyll ~2.7 µg/L) in 2019, and low nutrients (phosphorus ~17 µg/L) in 2019. After 6 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 2023, but LakeList holds no readings after 2020 — check the station reports for anything newer.
