Voltz Lake

Voltz Lake sits at the top of the Wisconsin DNR grading rubric with an A, a mark reached by the cleanest lakes in Wisconsin. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

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. A maximum depth of 24 ft puts Voltz Lake in the middle of Wisconsin's depth distribution. The lake is compact at 61 acres, with partial shoreline records and little volume to buffer nutrient inputs. Among the 13 graded lakes in Kenosha County, Voltz Lake ranks 3 — in the top quartile locally.

Voltz Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery is bass-led, with 4 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
