Wp22-T4a Lake

Wp22-T4a Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Wisconsin average. 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.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. 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-T4a Lake ranks 37 of 40 in Douglas County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Wp22-T4a Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Wp22-T4a 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.
