Common questions
What fish are in Schwappauf Lake?
Minnesota DNR's Standard Survey on August 4, 1992 caught 2.50 northern pike per gill net at Schwappauf Lake. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Schwappauf Lake last surveyed?
The most recent fisheries survey on file for Schwappauf Lake is dated August 4, 1992. 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 Schwappauf Lake stocked?
No stocking record for Schwappauf 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 Schwappauf Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Schwappauf Lake’s water-quality measurements separately, and the water-quality trend over 2 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.
