Double Lake

On the LakeGrade rubric Double Lake fails the cutoffs — a TSI of 78 and persistent algal pressure put it in the bottom tier.

Hypereutrophic conditions mean the lake is operating at the upper end of the productivity scale, with all the bloom risk that implies. 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 6 graded lakes of Cottonwood County, Double Lake sits at rank 5, near the bottom of the county list.

Double Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Double Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Double Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
