Common questions
What fish are in Triangle Lake?
Minnesota DNR's Standard Survey on July 20, 2020 caught 9.89 walleye per gill net at Triangle Lake. Length samples in the latest survey that recorded them ran 7–28 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 Triangle Lake last surveyed?
The most recent fisheries survey on file for Triangle Lake is dated July 20, 2020. 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 Triangle Lake stocked?
Minnesota DNR publishes a stocking history for Triangle 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.
Do the water-quality readings tell me how Triangle Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Triangle Lake’s water-quality measurements separately. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
Water-quality readings are 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 with clear, low-nutrient water can still carry a meal limit on larger predator fish.
