Little Armstrong Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Little Armstrong Lake average 5.23 largemouth bass per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated July 9, 2018. Length samples in the latest survey that recorded them ran 5–16 inches. In St. Louis County, Minnesota, Little Armstrong Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Water clarity averages 15.5 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.
Species recorded at Little Armstrong Lake
2 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.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Little Armstrong Lake — official chemistry is on file, not a letter, and the water-quality trend over 6 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Little Armstrong Lake?
Minnesota DNR surveys at Little Armstrong Lake average 5.23 largemouth bass per unit of sampling effort (CPUE) across 2 surveys. The most recent is a Standard Survey dated July 9, 2018. Length samples in the latest survey that recorded them ran 5–16 inches. Minnesota DNR lists 2 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 Little Armstrong Lake last surveyed?
The most recent fisheries survey on file for Little Armstrong Lake is dated July 9, 2018. 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 Little Armstrong Lake stocked?
No stocking record for Little Armstrong 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 Little Armstrong 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 Little Armstrong Lake — official chemistry is on file, not a letter, and the water-quality trend over 6 years of monitoring is stable. 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.
