Common questions
What fish are in Langdon Lake?
Minnesota DNR's Standard Survey on July 6, 1993 caught 94.50 black bullhead per gill net at Langdon Lake. Length samples in the latest survey that recorded them ran 4–11 inches. Minnesota DNR lists 8 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 Langdon Lake last surveyed?
The most recent fisheries survey on file for Langdon Lake is dated July 6, 1993. 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 Langdon Lake stocked?
No stocking record for Langdon 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 Langdon Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Langdon 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.
