Lake Alice

Lincoln County, WisconsinEutrophic

Lake Alice sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. 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. Lake Alice ranks 15 of 19 in Lincoln County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Lake Alice — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Lake Alice, which usually reflects a lack of formal fisheries survey work rather than an empty lake. 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.
