Minnesota DNR surveys at Typo Lake average 3.92 walleye per unit of sampling effort (CPUE) across 7 surveys. The most recent is a Standard Survey dated June 14, 2016. Length samples in the latest survey that recorded them ran 7–23 inches.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Typo Lake F from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.
