Historical volunteer-monitoring record for this lake.
Last sampled Aug 2011Volunteer monitoring 2009–2011
DNR volunteers monitored this lake for about 2 years, ending in 2011. Its final monitored summers showed hazy water (~3.5 ft Secchi) in 2009, high algae (chlorophyll ~71 µg/L) in 2011, and high nutrients (phosphorus ~97 µg/L) in 2011. After 15 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 2015, but LakeList holds no readings after 2011 — check the station reports for anything newer.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
