Unnamed Lake
Oneida County, WisconsinLimited DataMesotrophic
Unnamed Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. 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.
Mesotrophic conditions dominate at Unnamed Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of just 12 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. The lake is compact at 2 acres, with partial shoreline records and little volume to buffer nutrient inputs. Unnamed Lake ranks 50 of 134 in Oneida County — solidly in the upper half of the local distribution.
Unnamed 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 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.
