DNR water check
Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Sep 2020Volunteer monitoring 2019–2020
DNR volunteers monitored this lake for about 1 years, ending in 2020. In 2020 the water showed clear water (~11.9 ft Secchi), very low algae (chlorophyll ~2.5 µg/L), and low nutrients (phosphorus ~17 µg/L). After 6 years without samples, these readings describe the lake as it was, not as it is.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2020 | 11.9 ft (2) | 2.5 µg/L (2) | 17.0 µg/L (1) |
| 2019 | 13.5 ft (3) | 3.0 µg/L (2) | — |

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2014 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 contextKorth Lake (WBIC 325400) only
Human-reviewed catch, CPUE, length, size-structure and growth metrics for exact Korth Lake.
- Historical survey snapshot; not current regulations or navigation guidance.
- Stocking histories, regulations, recommendations, comparison-water values and unsupported chart-only values were excluded.
