Wisconsin DNR fisheries surveys
Species recorded at Lake Tomah
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 |
|---|---|
| Panfish | Common |
| Largemouth Bass | Common |
| Northern Pike | Common |
Stocking at Lake Tomah
No stocking record for Lake Tomah 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.

Common questions
What fish are in Lake Tomah?
Wisconsin DNR lists Panfish as common on Lake Tomah. 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 Lake Tomah last surveyed?
No survey date is recorded for Lake Tomah beyond the results themselves. Wisconsin DNR publishes the underlying documents, which carry the sampling dates.
Is Lake Tomah stocked?
No stocking record for Lake Tomah 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 Lake Tomah fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Lake Tomah’s water-quality measurements separately, and the water-quality trend over 4 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
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.
