DNR fisheries survey

Minnesota DNR's Standard Survey on August 6, 2019 caught 1.33 walleye per gill net at Good Lake.

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

From the 2025-08-07 survey

Temperature and dissolved oxygen measurements were collected from the deepest basin in Good Lake on August 7th, 2025. This was done to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee, the most sensitive coldwater species present in this…
