Fairbanks Lake

Beltrami County, MinnesotaLimited DataMesotrophic

On the LakeGrade scale Fairbanks Lake grades a B, with clarity readings still being added and 22 µg/L of phosphorus placing it above the Minnesota median.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. 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. Fairbanks Lake sits at rank 61 of 92 in Beltrami County, in the lower half of the local distribution.

Fairbanks Lake has no invasive species recorded in Minnesota state databases as of 2020, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Fairbanks 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.
