Survey results in full
Minnesota DNR's Standard Survey on August 27, 2018 caught 8.00 walleye per gill net at Guernsey Lake.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Guernsey Lake’s water-quality measurements separately, and the water-quality trend over 2 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Guernsey Lake?
Minnesota DNR's Standard Survey on August 27, 2018 caught 8.00 walleye per gill net at Guernsey Lake. Minnesota DNR lists 16 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 Guernsey Lake last surveyed?
The most recent fisheries survey on file for Guernsey Lake is dated May 3, 2024. 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 Guernsey Lake stocked?
Minnesota DNR publishes a stocking history for Guernsey 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 Guernsey Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Guernsey Lake’s water-quality measurements separately, and the water-quality trend over 2 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.
