Alice Lake
Otter Tail County, MinnesotaLimited DataHypereutrophic
On the LakeGrade rubric Alice Lake fails the cutoffs — a TSI of 87 and persistent algal pressure put it in the bottom tier. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
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 97 graded lakes of Otter Tail County, Alice Lake sits at rank 97, near the bottom of the county list.
Alice Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Alice Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Alice Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
