Mt Maud Lake Inlet

On the scoring rubric Mt Maud Lake Inlet grades a D: clarity at 3.4 ft and phosphorus readings still being added keep it in the lower bracket for Cook County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

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. Within the 137 graded lakes of Cook County, Mt Maud Lake Inlet sits at rank 114, near the bottom of the county list.

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