Dads Lake

Vilas County, WisconsinLimited DataMesotrophic

Dads Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. Dads Lake reaches 15 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 52 acres, Dads Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Dads Lake sits at rank 113 of 191 in Vilas County, in the lower half of the local distribution.

No invasive species are currently listed at Dads Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 3 documented species across the lake's records. 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.
