Common questions
What fish are in Trestle Lake?
Minnesota DNR surveys at Trestle Lake average 13.90 largemouth bass per unit of sampling effort (CPUE) across 4 surveys. The most recent is a Standard Survey dated July 17, 2023. Length samples in the latest survey that recorded them ran 5–19 inches. Minnesota DNR lists 7 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 Trestle Lake last surveyed?
The most recent fisheries survey on file for Trestle Lake is dated July 17, 2023. 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 Trestle Lake stocked?
No stocking record for Trestle 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 Trestle Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Trestle Lake A from EPA Water Quality Portal chemistry. 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.
