Millicent Lake

On the LakeGrade rubric, Millicent Lake pulls an A: clarity at 75.5 ft and phosphorus readings still being added put it in the top bracket for Wisconsin. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI value of 15 puts Millicent Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. 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. Millicent Lake sits at rank 29 of 55 in Bayfield County, in the lower half of the local distribution.

Millicent Lake has no invasive species recorded in Wisconsin state databases as of 2021, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Millicent Lake, 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.
