Dix Lake

Lake County, MinnesotaLimited DataOligotrophic

Dix Lake earns an A — every scored parameter (clarity) rates among the best monitored waters in Lake County.

Trophically, Dix 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 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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
