North Twin Lake FishingNRNot rated for water quality
Minnesota DNR surveys at North Twin Lake average 8.20 largemouth bass per unit of sampling effort (CPUE) across 4 surveys. The most recent is a Standard Survey dated August 11, 2008. Length samples in the latest survey that recorded them ran 3–16 inches. In Itasca County, Minnesota, North Twin 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 13.5 feet of visibility, and there is one public boat landing. 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 North Twin Lake
No stocking record for North Twin 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 North Twin 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.

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 North Twin Lake?
Minnesota DNR surveys at North Twin Lake average 8.20 largemouth bass per unit of sampling effort (CPUE) across 4 surveys. The most recent is a Standard Survey dated August 11, 2008. Length samples in the latest survey that recorded them ran 3–16 inches. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was North Twin Lake last surveyed?
The most recent fisheries survey on file for North Twin Lake is dated August 11, 2008. 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 North Twin Lake stocked?
No stocking record for North Twin 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 North Twin 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 North Twin 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.
