Common questions
What fish are in Perch Lake?
Minnesota DNR surveys at Perch Lake average 13.49 largemouth bass per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated June 27, 2016. Length samples in the latest survey that recorded them ran 5–16 inches. Minnesota DNR lists 10 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 Perch Lake last surveyed?
The most recent fisheries survey on file for Perch Lake is dated June 27, 2016. 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 Perch Lake stocked?
Minnesota DNR publishes a stocking history for Perch 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.
Does the water-quality grade tell me how Perch Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Perch Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
A water-quality grade is 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 can grade well and still carry a meal limit on larger predator fish.
