Wiscobee Lake
Oconto County, WisconsinMesotrophic
On the LakeGrade rubric, Wiscobee Lake pulls an A: clarity at 18.9 ft and 22 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.
Mesotrophic conditions dominate at Wiscobee Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 40 ft puts Wiscobee Lake in the middle of Wisconsin's depth distribution. At 39 acres, Wiscobee Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Within the 66 graded lakes of Oconto County, Wiscobee Lake sits at rank 55, near the bottom of the county list.
An invasive species record — Chinese Mystery Snail — has been logged at Wiscobee Lake; Wisconsin DNR maintains the official infested-waters list. The fishery is bass-led, with 3 documented species across the lake's records. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
