Unnamed Lake
Vilas County, WisconsinLimited DataMesotrophic
Unnamed Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. Unnamed Lake reaches 26 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake is compact at 22 acres, with partial shoreline records and little volume to buffer nutrient inputs. Within the 202 graded lakes of Vilas County, Unnamed Lake sits at rank 182, near the bottom of the county list.
No invasive species are currently listed at Unnamed Lake — the lake remains off the Wisconsin 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. 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.
