Halverson Lake

On the scoring rubric Halverson Lake grades a D: clarity at 3.0 ft and 51 µg/L of phosphorus keep it in the lower bracket for Polk County. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. 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 20 graded lakes of Polk County, Halverson Lake sits at rank 17, near the bottom of the county list.

Halverson Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Halverson Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Halverson 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.
