Lk Superior .02 Mi N of Dutchman Creek Mouth Lake
Douglas County, WisconsinLimited DataEutrophic
Lk Superior .02 Mi N of Dutchman Creek Mouth Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
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. Lk Superior .02 Mi N of Dutchman Creek Mouth Lake ranks 35 of 40 in Douglas County — at the lower end of the locally monitored distribution.
No invasive species are currently listed at Lk Superior .02 Mi N of Dutchman Creek Mouth Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Lk Superior .02 Mi N of Dutchman 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.
