DNR water check
Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Jun 2019Volunteer monitoring 2009–2019
DNR volunteers monitored this lake for about 10 years, ending in 2019. Its final monitored summers showed clear water (~10.8 ft Secchi) in 2018, low algae (chlorophyll ~4 µg/L) in 2019, and very low nutrients (phosphorus ~8.7 µg/L) in 2018. After 7 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 2022, but LakeList holds no readings after 2019 — check the station reports for anything newer.

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2024 DNR fisheries survey. Population estimates, density, and catch-rate indices use different units, methods, and scopes, so each value is presented in its original form rather than normalized against a different measure.
Survey indicatorsValues keep their source unit and method; unlike measures are not scaled or compared.
Management contextLake-specific summer fyke-net panfish survey; largemouth bass, northern pike and yellow perch retain nontarget scope.
DNR documented moderate bluegill abundance and low catch rates for black crappie and nontarget gamefish.
- Target WBIC 2908500 comes from the exact LakeList queue match but is not printed in the PDF; sourceWaterbodyIds therefore remains empty.
- Rock bass and walleye are listed without exact counts and are excluded.
