DNR water check
Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Sep 2000Volunteer monitoring 1976–2000
DNR volunteers monitored this lake for about 24 years, ending in 2000. In 2000 the water showed clear water (~14 ft Secchi), very low algae (chlorophyll ~1.5 µg/L), and low nutrients (phosphorus ~16.5 µg/L). After 26 years without samples, these readings describe the lake as it was, not as it is.

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2022 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 contextA 2022 Spring Electrofishing II survey assessed Cedar Lake bass and panfish; northern pike were survey by-catch.
