Lk Superior .05 Mi N of Pearson Creek Mouth Lake
Douglas County, WisconsinLimited DataMesotrophic
Lk Superior .05 Mi N of Pearson Creek Mouth Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
A TSI near 48 places Lk Superior .05 Mi N of Pearson Creek Mouth Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. 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, Lk Superior .05 Mi N of Pearson Creek Mouth Lake ranks 26 — below the local median, though not at the bottom.
Lk Superior .05 Mi N of Pearson Creek Mouth 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 Lk Superior .05 Mi N of Pearson Creek Mouth Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
