Rose Lake FishingAWater-quality grade A
Minnesota DNR surveys at Rose Lake average 2.63 northern pike per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated August 8, 1991. In St. Louis County, Minnesota, Rose Lake carries an overall water-quality grade of A.

Stocking at Rose Lake
No stocking record for Rose 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.

From the 1991-08-08 survey
WAE POPULATION IS WELL BELOW STATE AND LOCAL AVERAGES. SPAWNING AREAS ARE NOT PRESENT. PRESENT WAE POPULATION IS NOT REPRESENTED BY THE 1988 FINGERLING STOCKING (4/LB) AND IS LIKELY THE RESULT OF STOCKING BY RESIDENTS (PERSONNEL COMMUNICATION). SOME LARGE NOP ARE PRESENT, HOWEVER, LACK OF SPAWNING AREAS KEEP…

Common questions
What fish are in Rose Lake?
Minnesota DNR surveys at Rose Lake average 2.63 northern pike per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated August 8, 1991. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Rose Lake last surveyed?
The most recent fisheries survey on file for Rose Lake is dated August 8, 1991. 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 Rose Lake stocked?
No stocking record for Rose 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 Rose Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Rose Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 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
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.
