DNR fisheries survey

Minnesota DNR's Standard Survey on June 24, 2024 caught 2.00 walleye per gill net at Horseshoe Lake.

A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Horseshoe 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.
