Unnamed Lake
Wright County, MinnesotaLimited DataEutrophic
Unnamed Lake earns an F: phosphorus readings still being added and clarity at 1.6 ft signal heavy nutrient loading from the surrounding watershed.
At a TSI of 70, Unnamed 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 64 graded lakes of Wright County, Unnamed Lake sits at rank 51, near the bottom of the county list.
No invasive species are currently listed at Unnamed Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Unnamed Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Unnamed 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.
