Wp22-T1b Lake

Douglas County, WisconsinLimited DataMesotrophic

Wp22-T1b 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. 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 Douglas County's 40 graded lakes, Wp22-T1b Lake ranks 22 — below the local median, though not at the bottom.

No invasive species are currently listed at Wp22-T1b Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Wp22-T1b 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.
