Minnesota DNR fisheries surveys · latest June 16, 2022
Species recorded at Stewart Lake
7 species on the Minnesota 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.
Stocking at Stewart Lake
No stocking record for Stewart 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.

Survey results in full
Minnesota DNR's Targeted Survey on June 16, 2022 caught 8.94 walleye per hour of electrofishing at Stewart Lake. Length samples in the latest survey that recorded them ran 7–15 inches.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Stewart Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2022-06-16 survey
A night electrofishing survey was completed on Stewart Lake on June 16th 2022 to determine if Largemouth Bass are present.

Common questions
What fish are in Stewart Lake?
Minnesota DNR's Targeted Survey on June 16, 2022 caught 8.94 walleye per hour of electrofishing at Stewart Lake. Length samples in the latest survey that recorded them ran 7–15 inches. Minnesota DNR lists 7 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 Stewart Lake last surveyed?
The most recent fisheries survey on file for Stewart Lake is dated June 16, 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 Stewart Lake stocked?
No stocking record for Stewart 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 Stewart Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Stewart Lake’s water-quality measurements separately, and the water-quality trend over 6 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 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.
