East Four-Legged Lake
Clearwater County, MinnesotaMesotrophic
On the LakeGrade scale East Four-Legged Lake grades a B, with clarity at 4.6 ft and 11 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. Within the 40 graded lakes of Clearwater County, East Four-Legged Lake sits at rank 34, near the bottom of the county list.
East Four-Legged 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 East Four-Legged Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
