| Species | Abundance |
|---|---|
| Panfish | Abundant |

Stocking at Iola Lake

Common questions
What fish are in Iola Lake?
Wisconsin DNR rates Panfish as abundant on Iola 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 Iola Lake last surveyed?
No survey date is recorded for Iola Lake beyond the results themselves. Wisconsin DNR publishes the underlying documents, which carry the sampling dates.
Is Iola Lake stocked?
No stocking record for Iola 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.
Do the water-quality readings tell me how Iola Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Iola Lake’s water-quality measurements separately, and the water-quality trend over 7 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
Water-quality readings are 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 with clear, low-nutrient water can still carry a meal limit on larger predator fish.
