Carman Lake

On the scoring rubric Carman Lake grades a D: clarity at 5.9 ft and phosphorus readings still being added keep it in the lower bracket for Becker County.

At a TSI of 52, Carman 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 93 graded lakes of Becker County, Carman Lake sits at rank 89, near the bottom of the county list.

No invasive species are currently listed at Carman Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Carman Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Carman Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
