Wisconsin DNR fisheries surveys
Wilson Lake FishingBWater-quality grade B
Wisconsin DNR rates Panfish and Largemouth Bass as abundant on Wilson Lake. In Iron County, Wisconsin, Wilson Lake carries an overall water-quality grade of B. Water clarity averages 11.0 feet of visibility, and there is one public boat landing. The survey figures on this page are Wisconsin DNR's own; the water-quality grade comes from EPA Water Quality Portal samples. Neither is a forecast of today's bite.
Species recorded at Wilson Lake
5 species on the Wisconsin DNR list for this lake. A species on the list has been recorded here; it does not mean it is catchable today or in every part of the lake.
How abundant each species is
Wisconsin DNR rates abundance from its own survey record rather than publishing a catch rate per species. The ratings below are theirs.
| Species | Abundance |
|---|---|
| Panfish | Abundant |
| Largemouth Bass | Abundant |
| Musky | Common |
| Northern Pike | Common |
| Smallmouth Bass | Present |
Stocking at Wilson Lake
No stocking record for Wilson Lake appears in the Wisconsin DNR material on file. That is an absence in the published record, not a confirmation that the lake is unstocked — some waters are managed as naturally reproducing and never appear in a stocking list at all.
Survey results in full
Wisconsin DNR rates Panfish and Largemouth Bass as abundant on Wilson Lake.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Wilson Lake B from EPA Water Quality Portal chemistry, and the water-quality trend over 7 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Wilson Lake?
Wisconsin DNR rates Panfish and Largemouth Bass as abundant on Wilson Lake. Wisconsin DNR lists 5 species for the lake in total. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Wilson Lake last surveyed?
No survey date is recorded for Wilson Lake beyond the results themselves. Wisconsin DNR publishes the underlying documents, which carry the sampling dates.
Is Wilson Lake stocked?
No stocking record for Wilson Lake appears in the Wisconsin DNR material on file. That is not the same as a confirmed unstocked lake: it means no stocking document was published for it in the records this page draws on.
Does the water-quality grade tell me how Wilson Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Wilson Lake B from EPA Water Quality Portal chemistry, and the water-quality trend over 7 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
A water-quality grade is not a consumption advisory. Mercury and PCB advice for Wisconsin waters comes from WI DNR/DHS, and it is issued per species and per size class — a lake can grade well and still carry a meal limit on larger predator fish.
