Head Lake

On the LakeGrade scale Head Lake grades a B, with clarity at 5.1 ft and 5 µg/L of phosphorus placing it above the Minnesota median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

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. Head Lake ranks 72 of 86 in Beltrami County — at the lower end of the locally monitored distribution.

Head Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Head Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
