Wolf Lake

Wolf Lake sits at the top of the Wisconsin DNR grading rubric with an A, a mark reached by the cleanest lakes in 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.

A TSI value of 31 puts Wolf Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. Wolf Lake is unusually deep for Wisconsin at 58 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. The lake is compact at 42 acres, with partial shoreline records and little volume to buffer nutrient inputs. Wolf Lake ranks 3 of 20 in Adams County, putting it in the upper tier of locally monitored lakes.

Eurasian watermilfoil is established at Wolf Lake, which can dampen recreational access and pressure the native plant community. The fishery is bass-led, with 4 documented species across the lake's records. A documented public access point at Wolf Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
