Hunters Lake

Waukesha County, WisconsinOligotrophic

On the LakeGrade rubric, Hunters Lake pulls an A: clarity at 32.8 ft and 16 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's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. Hunters Lake reaches 36 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake is compact at 54 acres, with partial shoreline records and little volume to buffer nutrient inputs. Hunters Lake ranks 6 of 48 in Waukesha County, putting it in the upper tier of locally monitored lakes.

Hunters Lake is on the Wisconsin infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. 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.
