Shishebogama Lake
Oneida County, WisconsinMesotrophic
On the LakeGrade rubric, Shishebogama Lake pulls an A: clarity at 10.0 ft and 14 µg/L of phosphorus put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. 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. Shishebogama Lake ranks 31 of 134 in Oneida County, putting it in the upper tier of locally monitored lakes.
No invasive species are currently listed at Shishebogama Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Shishebogama Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
