Turtle Lake East End

On the LakeGrade rubric Turtle Lake East End fails the cutoffs — a TSI of — and persistent algal pressure put it in the bottom tier. 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. Turtle Lake East End ranks 126 of 128 in Cook County — at the lower end of the locally monitored distribution.

Turtle Lake East End has no invasive species recorded in Minnesota state databases as of 2025, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Turtle Lake East End, 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.
