Latest individual samples: Secchi 2.5 ft (2026-07-11).
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 contextThe report is specific to Tainter Lake, with some walleye spring electrofishing effort extending into the lower Red Cedar River. Every metric retains its report-stated gear and location scope rather than combining netting, river and lake electrofishing rates.
The 2022 comprehensive spring survey found abundant walleye, smallmouth bass and yellow perch with strong size structure, lower northern pike and largemouth bass abundance, moderate bluegill and black crappie abundance, and fast-growing panfish supported by natural reproduction.
- Spring walleye values include both Tainter Lake and the lower Red Cedar River where explicitly stated by the report.
- DNR recommended habitat and water-quality work, continued five-year monitoring, and consideration of northern pike and panfish regulation changes with public input.

Depth FAQ
How deep is Tainter Lake?
Tainter Lake is 37 feet deep at its deepest point and averages about 14 feet, according to Wisconsin DNR records.
Is there a free depth map of Tainter Lake?
Yes. LakeList publishes a free interactive depth contour map of Tainter 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 Tainter 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.
