Swede Lake Inlet

Cook County, MinnesotaLimited Data

Swede Lake Inlet earns an F: phosphorus readings still being added and clarity at -324.8 ft signal heavy nutrient loading from the surrounding watershed. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

There is not yet enough seasonal data to settle the lake's trophic classification — the TSI window remains too narrow to call. 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. Swede Lake Inlet ranks 134 of 137 in Cook County — at the lower end of the locally monitored distribution.

Swede Lake Inlet has no invasive species recorded in Minnesota state databases as of 2021, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Swede Lake Inlet, 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.
