Little Kandiyohi Lake
Kandiyohi County, MinnesotaHypereutrophic
On the LakeGrade rubric Little Kandiyohi Lake fails the cutoffs — a TSI of 84 and persistent algal pressure put it in the bottom tier. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.
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. Little Kandiyohi Lake covers 1,237 acres alongside partial shoreline records, large enough that conditions can vary meaningfully between bays. Within the 35 graded lakes of Kandiyohi County, Little Kandiyohi Lake sits at rank 32, near the bottom of the county list.
No invasive species are currently listed at Little Kandiyohi Lake — the lake remains off the Minnesota infested-waters roster. 3 fish species are documented at Little Kandiyohi Lake, a mixed warm-water community typical for Minnesota lakes of this size. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
