Papoose Lake

On the scoring rubric Papoose Lake grades a D: clarity at 6.0 ft and phosphorus readings still being added keep it in the lower bracket for Lake County.

At a TSI of 51, Papoose Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. 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 142 graded lakes of Lake County, Papoose Lake sits at rank 130, near the bottom of the county list.

Papoose 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 Papoose 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.
