Stocking at Fraser Lake
No stocking record for Fraser 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.
Survey results in full
Minnesota DNR's Standard Survey on September 16, 1986 caught 1.00 lake trout per gill net at Fraser Lake.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Fraser Lake’s water-quality measurements separately, and the water-quality trend over 5 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2025-08-03 survey
Temperature and dissolved oxygen measurements were collected from the deepest basin in Fraser Lake on August 3rd, 2025. This was done to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Trout, the most sensitive coldwater species present in this lake (Cisco, also…

Common questions
What fish are in Fraser Lake?
Minnesota DNR's Standard Survey on September 16, 1986 caught 1.00 lake trout per gill net at Fraser Lake. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Fraser Lake last surveyed?
The most recent fisheries survey on file for Fraser Lake is dated August 3, 2025. 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 Fraser Lake stocked?
No stocking record for Fraser 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.
Do the water-quality readings tell me how Fraser Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Fraser Lake’s water-quality measurements separately, and the water-quality trend over 5 years of monitoring is declining. 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.
