Latest individual samples: Secchi 71 ft (2025-07-20), chlorophyll-a 13 µg/L (2025-08-23), and total phosphorus 21 µg/L (2023-06-21).
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 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 late-spring fyke-net adult-muskellunge estimate.
DNR estimated 80 adult muskellunge, or 0.4 adult fish per acre, with balanced size structure.
- The public PDF does not print a source waterbody ID; target WBIC 2301800 comes from the exact LakeList queue match and is used only as a migration gate.
- Other species are listed without exact counts and are excluded.

Depth FAQ
How deep is Echo Lake?
Echo Lake is 25 feet deep at its deepest point and averages about 9 feet, according to Wisconsin DNR records.
Is there a free depth map of Echo Lake?
Yes. LakeList publishes a free interactive depth contour map of Echo Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Echo Lake depth map come from?
The interactive depth contours are derived from LakeList depth model. Each contour set passes a visual QA review against the source document before it is published. The depths are a modeled estimate calibrated to the lake's documented maximum depth - not a survey, and not for navigation.
