Swede Lake Deep

On the LakeGrade rubric Swede Lake Deep fails the cutoffs — a TSI of — and persistent algal pressure put it in the bottom tier.

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 Deep ranks 112 of 128 in Cook County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Swede Lake Deep — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Swede Lake Deep, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
