Unnamed Lake
Langlade County, WisconsinLimited DataEutrophic
Unnamed Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Wisconsin average.
At a TSI of 57, Unnamed Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. At only 8 ft deep, Unnamed Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. At 8 acres, Unnamed Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Unnamed Lake ranks 29 of 32 in Langlade County — at the lower end of the locally monitored distribution.
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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
