Wolf Lake

On the LakeGrade rubric, Wolf Lake pulls an A: clarity at 27.9 ft and phosphorus readings still being added put it in the top bracket for Wisconsin. 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.

Trophically, Wolf Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. Wolf Lake reaches 17 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 22 acres, Wolf Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Among the 29 graded lakes in Portage County, Wolf Lake ranks 5 — in the top quartile locally.

Wolf Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Walleye are documented at Wolf Lake, one of 4 fish species on record for the lake. A documented public access point at Wolf Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
