Species recorded at Lewis Lake

Stocking at Lewis Lake
No stocking record for Lewis Lake appears in the Minnesota 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.

Minnesota DNR's Targeted Survey on July 18, 2022 caught 0.22 northern pike per trap net at Lewis Lake. Length samples in the latest survey that recorded them ran 19–22 inches.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Lewis Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Lewis Lake?
Minnesota DNR's Targeted Survey on July 18, 2022 caught 0.22 northern pike per trap net at Lewis Lake. Length samples in the latest survey that recorded them ran 19–22 inches. Minnesota DNR lists 11 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 Lewis Lake last surveyed?
The most recent fisheries survey on file for Lewis Lake is dated July 18, 2022. Survey intervals vary by lake and by species; a gap of several years between surveys is normal and does not mean the record is missing.
Is Lewis Lake stocked?
No stocking record for Lewis Lake appears in the Minnesota 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 Lewis Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Lewis Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is stable. 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 Minnesota waters comes from MDH, 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.
