Common questions
What fish are in Iverson Lake?
Minnesota DNR's Standard Survey on June 12, 1985 caught 4.00 walleye per gill net at Iverson Lake. Minnesota DNR lists 6 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 Iverson Lake last surveyed?
The most recent fisheries survey on file for Iverson Lake is dated June 12, 1985. 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 Iverson Lake stocked?
Minnesota DNR publishes a stocking history for Iverson 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 Iverson Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Iverson Lake’s water-quality measurements separately. Catch rate is not a swim clearance and is not a weekly bite report.

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.
