Mi50b Lake

On the LakeGrade rubric, Mi50b Lake pulls an A: clarity readings still being added and phosphorus readings still being added put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Mi50b Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. 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 Door County's 11 graded lakes, Mi50b Lake ranks 6 — below the local median, though not at the bottom.

Mi50b 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 Mi50b 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.
