A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade.

Common questions
What fish are in Upper Cullen Lake?
Minnesota DNR surveys at Upper Cullen Lake average 11.37 largemouth bass per unit of sampling effort (CPUE) across 10 surveys. The most recent is a Targeted Survey dated September 2, 2021. Length samples in the latest survey that recorded them ran 2–19 inches. Minnesota DNR lists 14 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 Upper Cullen Lake last surveyed?
The most recent fisheries survey on file for Upper Cullen Lake is dated September 2, 2021. 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 Upper Cullen Lake stocked?
No stocking record for Upper Cullen Lake appears in the Minnesota DNR material on file. That is not the same as a confirmed unstocked lake: it means no stocking document was published for it in the records this page draws on.
Does the water-quality grade tell me how Upper Cullen Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Upper Cullen 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.
