Unnamed Lake
Oneida County, WisconsinLimited DataEutrophic
On the scoring rubric Unnamed Lake grades a D: clarity at 6.6 ft and phosphorus readings still being added keep it in the lower bracket for Oneida County. 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.
At a TSI of 50, Unnamed Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 154 acres, Unnamed Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Unnamed Lake ranks 136 of 140 in Oneida County — at the lower end of the locally monitored distribution.
Unnamed Lake has no invasive species recorded in Wisconsin state databases as of 2020, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Unnamed 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.
