DNR fisheries survey

Minnesota DNR's Standard Survey on September 15, 1986 caught 4.00 lake trout per gill net at Wisini Lake.

A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Wisini Lake’s water-quality measurements separately, and the water-quality trend over 5 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.
