Wheeler North Lake

Kandiyohi County, MinnesotaHypereutrophic

On the LakeGrade rubric Wheeler North Lake fails the cutoffs — a TSI of 82 and persistent algal pressure put it in the bottom tier. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

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 Kandiyohi County's 35 graded lakes, Wheeler North Lake ranks 26 — below the local median, though not at the bottom.

No invasive species are currently listed at Wheeler North Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Wheeler North Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. 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.
