Wp22-T2a Lake
Douglas County, WisconsinLimited DataMesotrophic
On the LakeGrade scale Wp22-T2a Lake grades a B, with clarity at 10.8 ft and phosphorus readings still being added placing it above the Wisconsin median. 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. Wp22-T2a Lake sits at rank 25 of 40 in Douglas County, in the lower half of the local distribution.
Wp22-T2a Lake has no invasive species recorded in Wisconsin state databases as of 2022, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Wp22-T2a 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.
