Unnamed Lake -Deep Hole

On the scoring rubric Unnamed Lake -Deep Hole grades a D: clarity at 5.7 ft and phosphorus readings still being added keep it in the lower bracket for Oneida County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At only 8 ft deep, Unnamed Lake -Deep Hole is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. The lake is compact at 3 acres, with partial shoreline records and little volume to buffer nutrient inputs. Unnamed Lake -Deep Hole ranks 119 of 134 in Oneida County — at the lower end of the locally monitored distribution.

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