Wisconsin DNR fisheries surveys
Potato Lake FishingCWater-quality grade C
Wisconsin DNR rates Northern Pike as abundant on Potato Lake. In Washburn County, Wisconsin, Potato Lake carries an overall water-quality grade of C. Water clarity averages 9.9 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 Potato Lake
3 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 |
|---|---|
| Northern Pike | Abundant |
| Largemouth Bass | Common |
| Panfish | Present |
Stocking at Potato Lake

Common questions
What fish are in Potato Lake?
Wisconsin DNR rates Northern Pike as abundant on Potato Lake. Wisconsin DNR lists 3 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 Potato Lake last surveyed?
No survey date is recorded for Potato Lake beyond the results themselves. Wisconsin DNR publishes the underlying documents, which carry the sampling dates.
Is Potato Lake stocked?
No stocking record for Potato 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 Potato Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Potato Lake C from EPA Water Quality Portal chemistry, and the water-quality trend over 3 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.
