Survey results in full
Minnesota DNR's Targeted Survey on May 3, 2016 caught 0.12 walleye per trap net at Mandall Lake.

Common questions
What fish are in Mandall Lake?
Minnesota DNR's Targeted Survey on May 3, 2016 caught 0.12 walleye per trap net at Mandall Lake. Minnesota DNR lists 5 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 Mandall Lake last surveyed?
The most recent fisheries survey on file for Mandall Lake is dated May 3, 2016. 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 Mandall Lake stocked?
No stocking record for Mandall 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 Mandall Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Mandall Lake’s water-quality measurements separately, and the water-quality trend over 6 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 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.
