Common questions
What fish are in Johanna Lake?
Minnesota DNR's Standard Survey on June 27, 2022 caught 1.00 walleye per gill net at Johanna Lake. 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 Johanna Lake last surveyed?
The most recent fisheries survey on file for Johanna Lake is dated June 27, 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 Johanna Lake stocked?
Minnesota DNR publishes a stocking history for Johanna Lake. It records which species were released, in what numbers and in which years — the source documents are linked further down this page. A lake can be stocked in some years and not others, so read the years rather than assuming an annual release.
Do the water-quality readings tell me how Johanna Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Johanna 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.
