White Lake
Langlade County, WisconsinOligotrophic
White Lake earns an A — every scored parameter (clarity and phosphorus) rates among the best monitored waters in Langlade County. clarity and phosphorus rate similarly, so there is no obvious single lever to pull on watershed management.
Trophically, White Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. White Lake reaches 42 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. White Lake covers 153 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. White Lake ranks 1 of 32 in Langlade County, putting it in the upper tier of locally monitored lakes.
White Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Walleye are documented at White Lake, one of 5 fish species on record for the 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.
