Historical volunteer-monitoring record for this lake.
Last sampled Aug 1997
The last DNR samples for this lake are from 1997, when the water showed hazy water (~3.9 ft Secchi) and moderate nutrients (phosphorus ~28 µg/L). After 29 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 2022, but LakeList holds no readings after 1997 — check the station reports for anything newer.

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 2024 survey combining early-spring fyke netting/electrofishing for walleye, later fyke netting for muskellunge and late-spring electrofishing for bass and panfish.
DNR found low-density adult walleye, bluegill, largemouth-bass, pumpkinseed and yellow-perch populations; black crappie abundance was high and muskellunge density moderate.
- Qualitative density and size-structure statements are not converted into numeric metrics.
- White sucker presence is retained only in narrative because no exact count was reported.

Depth FAQ
How deep is Spider Lake?
Spider Lake is 25 feet deep at its deepest point and averages about 12 feet, according to Wisconsin DNR records.
Is there a free depth map of Spider Lake?
Yes. LakeList publishes a free interactive depth contour map of Spider Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Spider 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.
