Anna Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Anna Lake average 11.56 northern pike per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated July 6, 1989. In Crow Wing County, Minnesota, Anna Lake has no letter grade — the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Water clarity averages 11.5 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.
Stocking at Anna Lake
No stocking record for Anna 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 surveys at Anna Lake average 11.56 northern pike per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated July 6, 1989.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Anna Lake — official chemistry is on file, not a letter, and the water-quality trend over 6 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Anna Lake?
Minnesota DNR surveys at Anna Lake average 11.56 northern pike per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated July 6, 1989. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Anna Lake last surveyed?
The most recent fisheries survey on file for Anna Lake is dated July 6, 1989. 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 Anna Lake stocked?
No stocking record for Anna 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 Anna 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 Anna Lake — official chemistry is on file, not a letter, and the water-quality trend over 6 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.
