Wp22-T3a Lake
Douglas County, WisconsinLimited DataEutrophic
On the scoring rubric Wp22-T3a Lake grades a D: clarity at 5.4 ft and phosphorus readings still being added keep it in the lower bracket for Douglas County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
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. Within the 40 graded lakes of Douglas County, Wp22-T3a Lake sits at rank 38, near the bottom of the county list.
Wp22-T3a 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-T3a 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.
