Little Kettle Lake

Little Kettle Lake earns an F: phosphorus readings still being added and clarity at 3.3 ft signal heavy nutrient loading from the surrounding watershed.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within the 33 graded lakes of Carlton County, Little Kettle Lake sits at rank 33, near the bottom of the county list.

Little Kettle Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Little Kettle Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
