Dix Lake

Dix Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Lake County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. 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 Lake County's 142 graded waters, Dix Lake sits at rank 13, near the top of the local distribution.

Dix Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Dix Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Dix Lake — most use is by shoreline residents and their guests. 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.
