Trillium Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Trillium Lake average 4.60 northern pike per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated June 24, 2002. Length samples in the latest survey that recorded them ran 12–33 inches. In Cass County, Minnesota, Trillium Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Water clarity averages 11.2 feet of visibility. The survey figures on this page are Minnesota DNR's own; the water-quality grade comes from EPA Water Quality Portal samples. Neither is a forecast of today's bite.
Species recorded at Trillium Lake
8 species on the Minnesota DNR list for this lake. A species on the list has been recorded here; it does not mean it is catchable today or in every part of the lake.
Stocking at Trillium Lake
No stocking record for Trillium Lake appears in the Minnesota DNR material on file. That is an absence in the published record, not a confirmation that the lake is unstocked — some waters are managed as naturally reproducing and never appear in a stocking list at all.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Trillium Lake — official chemistry is on file, not a letter, and the water-quality trend over 4 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE means more abundant in standardized sampling. This is not a weekly bite report.

Common questions
What fish are in Trillium Lake?
Minnesota DNR surveys at Trillium Lake average 4.60 northern pike per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated June 24, 2002. Length samples in the latest survey that recorded them ran 12–33 inches. Minnesota DNR lists 8 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 Trillium Lake last surveyed?
The most recent fisheries survey on file for Trillium Lake is dated June 24, 2002. 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 Trillium Lake stocked?
No stocking record for Trillium 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 Trillium Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Trillium Lake — official chemistry is on file, not a letter, and the water-quality trend over 4 years of monitoring is improving. 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.
