Latest individual samples: Secchi 8 ft (2025-07-26), chlorophyll-a 5 µg/L (2025-08-25), and total phosphorus 23 µg/L (2024-08-23).
Secchi clarity is how deep a black-and-white disk stays visible from the surface — more feet means clearer water.
Chlorophyll-a is an algae pigment; higher values signal more algae in the water column.
Total phosphorus is a nutrient that feeds algae and aquatic plants. It is not a weed survey — depth, bottom type, water movement, and management change the actual lake experience.

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 Spooner Lake assessment used spring fyke nets and late-spring electrofishing to evaluate northern pike, largemouth bass, and panfish.

Depth FAQ
How deep is Spooner Lake?
Spooner Lake is 17 feet deep at its deepest point and averages about 7 feet, according to Wisconsin DNR records.
Is there a free depth map of Spooner Lake?
Yes. LakeList publishes a free interactive depth contour map of Spooner Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Spooner Lake depth map come from?
The interactive depth contours are derived from C-MAP Genesis community sonar (derived). Each contour set passes a visual QA review against the source document before it is published. The depths are derived from community sonar recordings (C-MAP Genesis Social Map, used with permission), with gaps between recordings interpolated; not for navigation.
